ABSTRACT
The present investigation entitled “Influence of pollination levels on the fruit set, yield and quality of kiwifruit (Actinidia deliciosa Chev.)” was carried out in the experimental orchards of the Department of Fruit Science, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, District Solan (Himachal Pradesh). These studies were conducted to know the effect of different pollination levels on the fruit set and quality of kiwifruit. Flowers of cv. Allison was pollinated after manipulating the number of styles and retaining 1,2,4,6,8,10,14,16,20,24 and all styles. High fruit set was recorded irrespective of the number of styles pollinated. Fruit growth was measured at 15 days interval. Initially there was a rapid increase in fruit growth for 40 days and there after slowed down till harvest. When flowers with only one style were pollinated, minimum fruit weight and number of seeds were recorded. A proportionate increase in fruit weight and number of seeds was observed with increase in the number of styles and maximum fruit weight and number of seeds were recorded when flowers with all styles were pollinated. Both the staminate cultivars proved to be effective pollinizers for the commercial pistillate cultivars.
