Usually in Northern hemisphere blooming in mangoes start

Usually in Northern hemisphere, blooming in mangoes start from late January and 1st flush arises in February–March (Mukherjee and Rao, 1943). Besides the variations regarding flowering time in different mango growing areas of the world, there are extensive variations with respect to different cultivars/varieties growing under similar conditions in the same areas. Therefore, it appears that initiation of mango blooming is a specific varietal trait (Mukherjee and Rao, 1943). Generally, each panicle bears 300–4000 PI-103 and in some cases it may even bears 9000 flowers. Furthermore, 600–6,000 numbers of panicles per tree has been reported (Iyer and Degani, 1997). Lower panicle portion bears less number of perfect flowers, as compared to terminal portion (Mukherjee and Rao, 1943). Usually, under normal conditions approximately 66% flowers remains unpollinated which is a major drawback of low fruit set percentage and it\'s also genotype specific trait. In grafted varieties about 3–35% flowers are pollinated under natural conditions (Mukherjee and Rao, 1943).
