摘要
本文分析了短蔓资源 1A5 33和商用品种“安农 2号”与“状元”的株型性状 ,结果表明 :1A5 33的节间长度、叶柄长度、蔓粗和柄蔓夹角均小于 2个商用品种 ,尤其是节间长度远远小于 2个商用品种 ,说明这些性状 ,尤其是节间长度性状有助于甜瓜株型改良。但 1A5 33的叶面积和单株产量低于商用品种 ,说明这 2个性状较差 。
In the paper, the plant type chatacters of short-internode resource 1A533 and 2 commercial varieties 'Anong No.2 'and 'Zhuangyuan' were analyzed. The results showed that the lenth of internode and leaf stalk, the size of stem and leaf stalk-stem angle in 1A533 were shorter or smaller than that of 2 commercial verieties, especially for the lenth of internode. The results indicated that thess characters in 1A533 were adapted to inprove plant type of melon. However, leaf area and yield per plant in 1A533 were smaller of lower than that of 2 commercial varieties. It indicated that these 2 characters in 1A533 need to improver by breeders.
