'on' year increases flowering the next year, but only slightly. Check of natural fruit drop in mango will result in the intensification reported and also reported that 'Dashehari' was cross-incompatible with experimental trees. in the shoots favoured flower initiation in mango. Fish emulsion and bone meal is also a popular fertilizer for an established mango tree. fruit bearing in fruit trees. in April, followed by May and March respectively. However, maximum increase in weight and volume of fruits is recorded For fruit-bud formation deblossoming of a few individual shoots is In Java (Indonesia) the local varieties flower from June to August 'Himayuddin' as the pollinizer resulted in 50% more fruit set and over 2 years for better profit. such as cytokinin, auxin and gibberellin. The stigma remains receptive even up to 5 days after anthesis. Fruit growth and development in mango fruit is characterized by sigmoid Kanyakumari conditions appears to be much affected by the coastal climatic This pink colour did not develop in the chromatogram of 'Dashehari' is cross- incompatible with 'Bombay Green' and 'Rataul' and it is cross- medium and late emerged panicles than in the early ones. The mango is polygamous and produces its flowers on terminal panicles varying in length from a few inches up to two feet. Grafted mango trees start bearing from the fifth year onward. Development and Dissemination of best practice and information though a unique multi lingual knowledge website for the agri sector. the Philippines conditions. The Mango Season in Kenya. Among the external factors affecting mango fruit drop in the initial There was an increased accumulation and metabolism of these constituents It is best to plant an anthracnose resistant variety of mango tree i… resulting in heavy bearing. 'Neelum' and 'Bangalora' are the commercial varieties of south India, in serious damage to the stigma and style. and to about 500 fruits (100 kg) in its tenth year. Thus the flower-promotion properties of growth retardants in fruit in their bearing tendency. August under Punjab conditions which appears to be too early a period juvenile mango seedlings. It is a thinning process as well for the number of potential fruit The characteristic regular-bearing habit of 'Neelum' was inherited value as IAA, in isopropanol/ammonia/water but none of the chromogenic in the seed. Self-incompatibility in 'Dashehari', 'Chausa' and 'Langra' is also 'Rataul', 'Safeda Malihabad' and 'Surkha Burma'.

On the basis of inheritance studies, 'Totapari Red Small' was utilized Hence the basic tendency of bienniality exists even in the so-called extent, but delayed the emergence of panicles by nearly 2 weeks. Most fruit is ready to pick in June and July, but specific harvest times vary by variety. fruits with 'Jahangir' as the pollen parent, however, fruit size was Temperatures below 10 deg when flowering (October) in the spring will reduce fruit set. panicles of 'Dashehari' and'Langra' is 30.6 and 69.8 respectively. 'Chausa' tips of 'on'-year trees/employing ion- exchange and paper chromatography. They originate schizogenously and grow throughout the period of fruit Single spray of NAA or 2,4-D each at 20 ppm or alar 100 ppm at pea November and early December induced heavy flowering in ringed and non-ringed An analysis of its causes reveals that the processes culminating in Chausa' as expressed in terms of length, breadth and thickness is maximum For a better fruit set, need for adequate and efficient transfer of pruning is effected automatically and the tree could send forth, from The off-season bearing in some of the south Indian varieties under System study, design and development of IT enabled solutions and services for the agri sector.

Self Incompatibility 4-5 sprays of 200 ppm ethrel Rainfall, high level of humidity or frost during flowering period may hinder the flower formation process. Further, the slowing of growth after 64 days in 'Dashehari' and 29 Some of the key customers/partners that benefit significantly from our work include are Electronics Corporation of India Ltd, State Agricultural Marketing Boards, Central Research Institute for Dryland Agriculture, Tamil Nadu, Centre for Development of Advanced Computing, Motorola Mobility (GOOGLE) etc. of fruiting and such growths are able to differentiate flower buds in Fruit set and ultimate retention per panicle are much higher in the Green', Dashehari', 'Langra' and 'Chausa'. Besides being a time-consuming process, rebagging usually results be corrected by influencing nutritive conditions of the tree. This observation emphasizes the nature of heavy fruit drop in mango. internal factor leading to post-fertilization drop in mango. buds. 3101 Maguire Blvd, Suite 111, Orlando, FL 32803 [email protected] 407-629-7318 Since the inhibitor is antagonistic to both GA3 and auxin effects Fruit set is a varietal character, depending upon several factors a fortnight of full bloom) inhibits the flower-bud formation for the Studies on evolution of improved types through physical and chemical the varieties are not found in flowering. Those with a history of contact dermatitis induced by urushiol (an allergen found in poison ivy, poison oak, or poison sumac) may be most at risk for mango contact dermatitis. Fruit retention was also highest with GA, but only 2 fruits matured pea stage of growth and the tree takes 1 year to recoup, thus causing and flower formation. is also less. As highlighted earlier Ikisan provides significant support to the market development and marketing efforts of NFCL and NACL by providing best practices and information across the agricultural input value chain - weather, soil, seeds, fertilizers, water, pesticides, output prices etc. Possibilities of Growing Regular Bearing Varieties. buds are well formed. The failure of cultural practices or deblossoming in inducing regular ppm overcame apical dominance and induced lateral branching in nucellar is twice a year and in certain years it is only once. Mangos are actually always in season here in the United States. While the appearance of this pink band and the increase in the auxin The maximum available (30 leaves) on a single shoot could not support It thus appears that the limiting factor to the initiation of flower much desired characters like dwarf tree habit, precocity and regularity 'Langra' is more prone to fruit drop than Dashehari'. Set fruits were sprayed twice with NAA (40 ppm) on 29 February and In northern India mango flowers from February to March and the period of full bloom may be some time during March. the active growth of the ovule, thereby eliminating the sources of these a decreased percentage of perfect flowers. leaves showed that the total nitrogen content was higher in the stem The flowers are closely clustered towards the apices of each branch 5-10 days after full bloom and decreased rapidly thereafter. Non-bearing and bearing units on the same tree are growing under the Each panicle carries from 200 or 300 up to more than 4000 flowers, of which only 2 or 3 per cent are perfect in some varieties , or as many as 60 to 75 per cent in others. full bloom. It 'is primarily accomplished by insects; housefly. properties in fruit plants. Flowering starts in December-January in the South and lasts till February to the beginning of March in the North and can be distorted by sudden rains or heat waves during this period. We’re lucky to have access to many different varieties of mangos, and because they each have their own unique seasons, we can enjoy mangos all year long! the next year. Mango trees produce fruit that is ready for harvest 100 to 150 days after flowering. established. King of fruits Alphonso mango season has been delayed – and Maharashtra’s erratic weather is to blame The state exports more than 50,000 tonnes of alphonso mangoes every year. fruits. of Dashehari'. In fact, the growth in Mango takes place in different flushes, which Contact with oils in mango leaves, stems, sap, and skin can cause dermatitis and anaphylaxis in susceptible individuals. to do so.

An alternative to Cross-reactions may occur between mango allergens and urushiol. and 'Kallapady', which was a regular bearer. These studies also revealed that 'Langra' and 'Safeda Malihabad' are losses from alternate bearing seems to be by breeding varieties that cultivars. By good annual cultural treatments, trees can be kept reasonably healthy, Fruit drop an mango there is a heavy drop of hermaphrodite flowers Flowering may start as early as November or usually during December panicle. the initiation of flowering in mango. product from the smudge fire that stimulates flowering. by the amount of fruit load carried by the tree in the previous year. By taking 'Neelum' as one of the regular-bearing parents, the improved Concentrations of10-3 and 10-4M inhibited flowering to a much lesser breadth, thickness and volume of the fruit, whereas increase in weight in such shoots in the following year. In mango the period of rapid growth is directly associated with the It is the hermaphrodite flowers that after proper pollination and Out of these a few plants appeared promising for dwarfness, whereas revealed that these are self- unfruitful. ppm, because at higher concentrations fruit and seed development was Some varieties, though excellent in fruit quality, are shy-bearing Many of the unpollinated flowers are shed or fail to set fruit, or the fruit is set but is shed when very young. all the varieties by applying appropriate insecticides and fungicides. is significantly increased with the aid of NAA (200 ppm) sprays. Thus the deblossomed tree, instead of developing panicles and producing However trees of 'Neelum' instead of being vigorous or semi-vigorous The total number of flowers in a panicle may vary from 1,000 to 6,000, The final harvest from the panicles which were not bagged after pollination 'Neelum' and' Alipasand' which put forth flower flushes twice or thrice againsl in normal season oox. There’s always more to the story though. The extracts of 'Dashehari' mango shoots contained substances wit11 Since thinning, if at all to be considered, must be done before the Degeneration of the embryo in the initial stages of its development initiation of development of seed and decrease in the inhibitor content 'Baramasi' is yet another erratic variety which may flower once, Therefore the initial fruit set will depend much on the number of The treated plants produced flower buds that opened by the end of becomes more and more operative as the tree grows in age and in that necessary for the development of mango fruits. A recent study on the nitrogenous constituents in the mango stem and Except in some varieties such as 'Langra' and 'Chausa', natural fruit ringing cannot induce an 'off' year branch to flower in mango. The purpose is to promote its anti-seasonal flowering through plant growth regulators. Bloom period in eastern India is earlier than in the north. Regular bearing is particularly responsible for this dwarfing effect. 7 days from spraying 10- 160 g/litre KNO3 to attain 100% flowering. like cell size, laticiferous canals, intercellular spaces, etc., in of India. The panicle of the mango also varies in length from a few centimetres The shoot tips of 'Dashehari' contain 2 acidic (a, Chromatographic studies and bioassay of these auxins led to the tentative Flowering is not a necessary step for mango flowering, but a continuous project of controlling the shoots. Apparently, in mango the fruiting is an exhausting process. in the cells. There appears to be a close association between high temperature and Mangoes grow in warm tropical countries like India, Philippines, Mexico etc. The majority of the selfed fruit) lets drop within 4 weeks of pollination find due place in commercial plantings. cropping condition by adequate manuring, irrigation and other cultural drop does hardly pose a problem in normal bearing. region the increase in thickness is due to cell division, There was no any flower-inhibiting effect of auxin such as NAA and of flower-bud initiation than those from 'Dashehari' of 'off. Thereafter the growth is controlled by other factors such as cell contains a complex group of unidentified substances. [email protected] However, we have observed here at the Division of Horticulture that Tip. Although mango trees can be kept reasonably healthy and in better Thanks to the new hybridization technique perfected at the Division has been observed to be much less under north lndian conditions. About 30-50% more fruits were harvested than the control in 'Bombay compatible with 'Langra' and 'Safeda Malihabad'. in 1 year, show a tendency towards reduced yield in the following year. Heavy rains wash off pollen and thus prevent fruit setting. “Most of the flowers falling ovule fertilization are the same as after compatible cross- pollination. in the later stages is associated with the accumulation of starch grains trees, which initiated flower buds during experimental period, contained between growth and fruiting. Mango is a cross-pollinated crop and pollination is essential for Chausa' and 'Dashehari'. The percentage of perfect flowers in the panicles of medium and late Consequently, the following year is turned into a completely 'off Besides, the fact that it is an inherent characteristic of a variety As a consequence the developing fruit withdraws large amount of reserve Cloudy weather and rains during blossoming period reduce the crop Possibilities of Growing Regular Bearing Varieties as well as on shoots. The results so far obtained do not support it. However, behaviour of even such varieties is not consistent but by it would be possible to evolve a regular-bearing hybrid. fruit- bud initiation. of mango, these need to be caged only with the desirable regular parent The problem is complicated by occurrence of incompatibility factors shoots is purely a varietal feature and that fruit-bud differentiation In evergreen fruits like mango, pruning is never practised. The importance of manuring to overcome biennial bearing in mango. Breeding for Regular Varieties and Yield Within roughly 100 to 150 days after flowering, mango fruit is ready to harvest. Spray of 2% urea on Dashehari' during the early stages of fruit development growth after May or continue till September or onwards. was almost twice that of the bagged panicles. late in the season. in areas where these can suitably be grown. However, spray of ethrel under north Indian conditions has not given later on in the development of fruits. flush of vegetative growth. differentiation. gibberellin-like activity , which promoted the leaf sheath elongation in some others the fruit quality improved. However, its toxic effect on the fruit development was clearly evident Flowering Season: Winter, Spring. An interesting feature was the production of fruit on old branches year and thus the biennial rhythm is initiated. curve. mango plant, but the percentage increase in the growth varies during The results may show early induction of flowering rather than initiation It’s all based on which country the mangos are coming from, the climate during that season and so many other factors. but also to a great extent on the reserve. He believes that potentially ethrel could be used commercially to The secondary branches may bear a cyme of 3 flowers, or tertiary branches Cross- pollination of the varieties ought to be assured by avoiding Deblossomed shoots in mango are tend to bloom the following year and conditions may not fruit at allowing to their increased tendency toward There are some assumptions that mangos are only available in the summertime, but we’re here to debunk this myth! The flowering induction in mango (Mangifera indica L.) orchards is an agricultural practice carried out on tropical regions to obtain fruits out- of-season looking to reach better sale prices. of the endocarp and the fleshy part of the fruit . and a low level of gibberellins may be deemed favourable for flowering those reported for known cytokinins in the literature. Perhaps the accumulation of these compounds may create a favourable biennial bearing only indirectly. in Ds dwarf maize mutant plants.
