Abstract
The impact of different pollination modes on fruit yield and quality of wild and cultivated types of jamun (Syzygium cumini) showed that wild type of jamun had higher fertilization rates and better fruit retention under hand pollination, whereas open pollination showed improved fruit weight and quality parameters like total soluble sugars and phenol content. In contrast, cultivated types (GKVK-1 and GKVK-2) exhibited superior fruit set and pulp content under open pollination. Bagging consistently resulted in lowest fruit retention and quality among wild and cultivated types. Fruit biochemical parameters such as sugars and phenolics were generally highest in open-pollinated fruits in cultivated types, while wild types had slightly better performance under hand pollination. The findings underscore the importance of pollinator activity and suggested different pollination management for wild and cultivated types to optimize fruit yield and quality.
