Correlation analysis among main branch characters in Xanthoceras sorbifolia
In order to study bearing habit of Xanthoceras sorbifoliaBunge and provide theory basis for its pruning, length, basal diameter and tip diameter of mother branch were measured, and number of shoots, fertile floret, infertile floret, and fruitlet, single fruit weight, fruit width, burliness quantity and seed weight were counted. The results showed that the correlation coefficient of the number of bearing shoots is the largest among all mother branch characters, up to 0.567,so fruit quantity was closely related with number of bearing shoots. The fertile floret, tip diameter and basal diameter of bearing branch had significant correlation with the number of fruitlet, up to 0.823,0.669,0.534,showing that vigorous branch can set more fruit. The relationship between yield and diameter of bearing shoots and mother branches showed that bearing shoots with top diameter over 4mm,basal diameter over 5 mm and mother branches with top diameter over 7 mm,basal diameter over 9 mm could set fruit effectively, These results had great significance for developing a reasonable program for pruning.
