摘要
以中国农业科学院郑州果树研究所葡萄资源圃中保存的342个葡萄品种的成熟叶片为试材,采用度量性状与非度量性状相结合的调查方法,研究了供试葡萄品种的叶宽等9个度量性状和叶片形状等8个非度量性状,以期为进一步建立葡萄种质资源叶片性状数据库奠定基础。结果表明:现有栽培葡萄品种的叶片形状主要为楔形和五角形;9个度量性状具有明显的变异性,且与长度有关的度量性状变异系数均大于16.51%;主成分分析表明与长度有关的度量性状为第一主成分,与角度有关的为第二主成分,与比值有关的为第三主成分,累计贡献率达到77.186%。
The 342 grape varieties leaves in the grape resources of Zhengzhou Fruit Research Institute of CAAS were used as experimental materials,9 metric traits(e.g.leaf width) and 8 non-metric traits(e.g. leaf shape) of the leaves of 342 grape varieties from Zhengzhou Fruit Research Institute of CAAS were investigated by using the method of combining metric and non-metric traits,in order to lay a foundation for the further establishment of leaf traits database of grape germplasm resources.The results showed that the leaf shape of the leaves of common grape varieties was mainly wedge-shaped and pentagonal;all nine metric traits had significant variability and the coefficient of variation related to length was more than 16.51%;principal component analysis showed that the measurement character related to length was the first principal component,the second principal component related to angle and the third principal component related to ratio,and the cumulative contribution rate reached 77.186%.
