妃子笑荔枝果实性状与结果母枝的相关性

Correlation Between Characteristics of Litchi Fruit (Litchi chinensis Sonn.) and Its Bearing Branches

分析了妃子笑荔枝(LitchichinensisSonn.cv.Feizixiao)果实性状与结果母枝性状的相关性。结果表明:妃子笑结果母枝叶篷数与其长度呈正相关;果实个数与枝产量、果纵径呈正相关,与核纵径呈负相关;枝产量、果实个数、果纵径、果横径均与结果母枝直径呈正相关;且以上相关均达极显著水平。当结果母枝的直径在0.80～1.01 cm时,其枝产量随之增加。

The results showed that there was a positive correlation between the length of bearing branches and the number of leaf whorl. The number of fruits were positively correlated with the yield of each branch and the vertical diameter of a fruit but negatively correlated with the vertical diameter of fruit stone. The yield and number of each branch, the vertical diameter and the transverse diameter of fruit showed significant positive correlation with the size of the bearing shoots. The yield of each branch increased along with the diameter of bearing shoots (0.80～1.01 cm in diameter).
