Abstract
ABSTRACT
The present study entitled “Statistical Investigation on influence of growth
characteristics on the production of Kiwifruit (Actinidia deliciosa Chev.)” was carried out
in Kiwi Block of Department of Fruit Science at the university campus (Dr Yashwant Singh
Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh) which was
established during 1985. Data were recorded on various growth characteristics (Plant height,
Vine girth, Vine spread, Number of bearing shoots per vine, Cane thickness, Number of leaves
per bearing shoot, Leaf area and Flower density) of Kiwifruit plant to assess their relative
contribution towards the yield. Kiwifruit yield was significantly and positively correlated with
number of bearing shoots per vine, vine girth, vine spread, plant height. The Kiwifruit growth
characteristics were subjected to principal components and factor analysis. Three out of nine
principal components were extracted for these growth characteristics of Kiwifruit which
explained 69.37 percent of the total variation of the original variables respectively. In case of
factor analysis in Kiwifruit, three basic factors were extracted for Kiwifruit plant which
explained 52.54 percent of total variation of the original variable. Most important characters
which contribute toward yield were plant height, vine girth and number of bearing shoots per
vine.
