摘　　要：以河南省郑州市11株广玉兰优树新采收的果实和种子为材料,研究了广玉兰果实和种子的表型变异情况。结果表明:广玉兰果实和种子具有丰富的表型变异,不同优树间果实和种子表型差异显著;果长、果宽分别与种子数呈极显著正相关和显著正相关关系;果长、果宽与种子长度和种子宽度呈正相关关系,果长、果宽、种长及种宽是果实和种子的关键表型性状。The fruits and seeds were collected from 11 superior trees of Magnolia grandiflora in Zhengzhou City of Henan Province, and their phenotypic variations were studied. The result showed that the phenotypic variations of the fruits and seeds were diverse, and the phenotypic differences of fruits and seeds were significant between different superior trees;There was a very significant positive correlation between the fruit length and the seed number and a significant positive correlation between the fruit diameter and the seed number;The fruit length and diameter presented a positive correlation with the seed length and width; The fruit length and diameter and the seed length and width were key phenotypic characters of the fruits and seeds.
