Mangoes Fall Before Ripe Due to Stress
Mango trees sometimes drop their fruit before it's ripe, which is a big problem for farmers.
This happens because the trees get stressed from things like drought or heatwaves.
When this happens, the tree's hormones get out of balance, and it decides to drop the fruit to save itself.
Scientists are studying this to find ways to help the trees keep their fruit.
They're using special treatments that act like a pep talk for the trees, telling them to hold onto the fruit.
This could help farmers grow more mangoes and make sure people have enough to eat.
It's not just about mangoes, though.
Other fruits like apples and avocados have the same problem, so this research could help lots of different crops.
Mango trees drop fruit prematurely due to environmental stress, causing significant economic and environmental losses.
Stress disrupts the tree's hormonal balance, triggering a 'quit signal' that leads to fruit drop.
Researchers are studying the molecular pathways behind this signal to develop management tools.
Plant growth regulators applied during flowering can increase tree yield by up to 17% in trials.
Understanding and managing fruit drop could benefit a wide range of fruit crops globally as the climate changes.
