Variation of Fruit Characters of Walnut under Different Elevations
摘要
Abstract
Morphological characteristics of Santai Walnut (Juglans sigllata) fruits growing in 7 areas with different elevations in Dayao County, Yunnan Province were mearsured. The data were processed by Software Excel, DPS, and SPSS 10.0. Significant differences were found among the fruits obtained from different elevations, in which those from elevation of 1 800 to 2 100 exhibited excellent seed quality. The index of the single fruit kernel weight varied magnificently, from 2.2 to 7.8 g with the variation coefficient CV 11.67％ followed by shell thickness (0.5～1.2 mm, CV 11.36％), single fruit weight (6.1～14.3 g,CV9.67％). The variations of nut size and kernel percent varied minimally,from 2.8 to 4.0 cm (CV 4.46％) and 44.47％ to 61.30％ (CV 52％) respectively.关键词
