| 摘 要： | 以盆栽法对中国结缕草属4个种的64份野生种源的匍匐茎生长速度进行了研究.结果表明,结缕草属植物不同种源利用匍匐茎进行营养繁殖时,变异很大,匍匐茎总长度和地上部生物量的变异系数分别为78.97%和33.00%;不同种间的匍匐茎总长度存在显著的差异,而地上部生物量无显著差异;结缕草Zoysia japonica的种内变异最大,细叶结缕草Z.tenuifolia的种内变异最小.

| Abstract: | The stolon growth rate of 64 accessions of Zoysia including 4 species were studied.The results showed that abundant variation was existed in the total stolon length and aboveground biomass of different accessions of zoysiagrass with the coefficient of variation as 78.97% and 33.00%,respectively.Siginificant difference and non-significant difference was existed in the total stolon length and aboveground biomass among species.The variation of Z.japonica was the highest among 4 species,and that of Z.tenuifolia was the lowest among 4 species. |
