Our main research subject is pollination and fertilization in Rosaceae - apple, pear, apricot, loquat and plum, are all cultivated in our region, the Upper Galilee. In Rosaceae self-pollen is rejected by the S-RNase-mediated gametophytic self-incompatibility (GSI) fertilization system. Therefor cross pollination between cultivars is essential for fruit set. We are studying the GSI mechanism, the flower physiology and pollination, including the addition of bumblebee, in related to yield quantity and fruit quality.
Lately we are also studying Avocado pollination and fertilization in order to further understand its fertilization system and identify new cultivars for the Israeli orchard.
Another area of our research is ripening of climacteric fruits. The research focuses on the molecular and physiological impact of the agent MCP1 which inhibits ethylene response and thus prolongs storage.
