摘　　要：本研究表明生态条件对茎秆节间大维管束数具有影响，与对一次枝梗数、颖花数等的影响具有同向效应；稻株茎秆各节间大维管束数在水稻群体中具有连续变异，具有数量性状的特征；对穗颈节间大维管束数的影响始于秧田期，本田期环境直接影响穗颈节间维管束分化。The research showed that ecological condition was of influence on the number oflarge vascular bundles in culm and it similarly effected the number of the primary branches of pani-cle,In the colony of rice,the number of large vascular bundles of the internodes was of successivevariation and could be taken as a quantitative character.Begining from nersery period. the numberof large vascular bundles of the first internode was influenced and in field growth period. it wasdirectly done to the differentiation.
