Dealing with fruit as your neighbor at times of climate change


Dealing with fruit as your neighbour at times of climate change


4th December 2019


Many fruit trees can naturally enter a biennial cycle of fruit production. In some crops farmers have useful procedures to reduce this tendency while in other crops we are still struggling for workable solutions. In apples, the presence of too many fruit inhibits summer flower induction in adjacent shoots while in olives, cold temperature winter induction of flowering is reduced if there is a ‘biochemical memory’ of many fruits harvested in the late fall. This involves several developmental processes including: natural fruitlet abscission in apples, cold winter flower induction in olives, and the molecular mechanism in which fruit load interferes with flower induction in both species. Here I will describe approaches and findings in our attempt to learn more about these processes.



Alon Samach is a molecular biologist studying developmental processes in plants.

His main current interests are the transition to flowering and fruitlet abscission in fruit trees, as well as breeding for new passionfruit cultivars.

His lab focuses on using experimental approaches to better understand processes such as alternate bearing in fruit trees and cold temperature induction of flowering in olives. His group also develops molecular markers for important traits in passionfruit breeding
