ASSISTED POLLINATION TECHNIQUES FOR IMPROVED FRUIT QUALITY DEVELOPMENT IN JACKFRUIT (ARTOCARPUS HETEROPHYLLUS LAM.)
Fruit deformation in jackfruit is common due to failure of some fruitlets to develop as a result of non-uniform outcrossing of its multicarpellar flowers which are anemophilous (wind-pollinated) with asynchronous stigmatic receptivity. This study was conducted to determine the effects of assisted pollination on fruit set and development in EVIARC Sweet jackfruit. Brushing off fresh pollen in the morning was found to be more effective than other pollen application techniques in improving fruit set and development. A high fruit set of up to 100% was obtained and typical fruit shape developed in contrast to naturally pollinated fruit which were slightly deformed. In addition, the number of fruitlets and seeds increased by more than 30% while the number of seeds per kg of fruit increased by 46%. Seedless fruitlets also increased by more than two-fold. The results indicate that assisted pollination could improve quality fruit development and increase edible yield.
