Embryo abortion in mango fruit linked to hormone levels, impacting fruit size.
The study looked at how hormones in mango fruit affect embryo development. They found that the critical period for embryo growth is around 20-30 days after fertilization. Differences in hormone levels between normal and aborted embryos affect fruit size. Higher levels of IAA and ABA were seen in aborted embryos, while lower levels of GA3 and ZT were found. Normal embryos had higher GA3 and ZT levels, which are important for development. Lower ratios of (GA3+IAA+ZT)/ABA in embryos and pulp led to smaller, seedless fruit. Overall, hormone levels play a crucial role in mango embryo development and fruit size.
