| 摘 要： | 在自然干旱条件下对桑树品种云桑1号、湘7920、湖桑32、育7-11、农桑8号、农桑9号夏伐后的夏秋季生长性能、产叶量等的测定分析表明:干旱会影响夏伐桑树的发芽数量、枝条长度、桑叶产量、叶质性状及产叶量,而且因品种不同,影响的程度有差异。品种受干旱影响的程度为:农桑8号>湘7920>云桑1号>农桑9号>育7-11>湖桑32。不同性状受干旱影响的程度是:枝条总长度>kg叶片数(叶片厚度)>枝条平均长度>单位条长产叶量>叶面积。综合比较,湖桑32号、育7-11在参试品种中较抗旱,湘7920虽然在干旱条件下的产量最高,但其重要性状指标的减少率也偏大,不宜作为抗旱品种。

| Abstract: | The results from determining the agronomical characters of Yunsang 1,Xiang 7920,Husang 32,Yu 7-11,Nongsang 8 and Nongsang 9 under the natural drought conditions after summer harvest,showed that the drought affected the germination quantity,branch length,leaf yield,leaf quality and leaf quantity.The degree of mulberry varieties affected by drought is Nongsang 8> Xiang 7920> Yunsang 1> Nongsang 9> Yu 7-11> Husang 32 and the degree of different agronomical characters affected by drought is total branch length> leaf quantity/kg> mean branch length> leaf yield(g/m)> leaf area.Husang 32 and Yu 7-11 are the mulberry varieties with the better drought resistance in the tested mulberry varieties by the integrated analysis. |
