贵州地区9个桑树耐旱材料产叶量与植物学性状之间的关系
Relationship between Leaf Yield and Botanical Characters of Nine Drought Tolerance Materials of Mulberry Trees in Guizhou Province
摘要
Abstract
The experiment was conducted with 9 mulberry drought-resistant materials including ZL10, HP11, HP8, DJ2, TSH, HCS, GSY12, DJ6 and HS32, 8 botanical characteristics including spring buds number, growth buds number, buds number of stopped growing, rate of growing buds, branch length of growing buds, spring branch length, leaves number per kilogram of spring and autumn, and also 6 yield indicators including leaf yield of growing buds, leaf yield per 1 m branch and plant leaf yield of spring and autumn, and plant leaf yield per year were investigated, aiming to find the main influencing factors of mulberry leaf yield through the correlation analysis between 14 indicators. The results showed that, in the nine mulberry varieties, the plant leaf yield per year had significant positive correlation with spring plant leaf yield, autumn leaf yield per 1 m branch, and autumn plant leaf yield, and the correlation coefficient were 0.850 (P＜0.01), 0.683 (P＜0.05), and 0.762 (P＜0.05), respectively. The autumn leaf yield per 1 m branch had a significant negative correlation with leaves number per kilogram of spring (P＜0.05) and autumn (P＜0.05), and autumn plant leaf yield also had a significant negative correlation with leaves number per kilogram of autumn (P ＜0.05). In conclusion, the less the leaves number per kilogram of spring and autumn was, the higher the spring leaf yield was, the higher the leaf yield per 1 m branch and plant leaf yield in autumn were, the plant leaf yield per year was also higher.关键词
