南充地区野生葎草构件性状多样性分析

为南充地区种质资源优质品种的选育提供实践指导和奠定理论基础，试验通过对4个葎草Humulus scandens种群的叶、茎、花序等构件的性状进行测定和分析，结果说明:不同葎草种群构件性状与数量呈现多样性，叶柄长、叶半径的变异系数分别为43.9% 和27.54%；其二级茎变异系数分别为86.33%、91.46%、76.36%和51.20%；三级茎的变异系数分别为81.83%、66.44%、52.35%和26.82%；节间长的变异系数分别为38.17%、49.77%、32%和48.34%；花序长、花序高度、小花数、花序半径、小花半径等都表现出较大的差异性。

Asexual reproduction component and its diversity of wild Humulus scandens in Nanchong

The asexual reproduction components of 4 populations of Humulus scandens in Nanchong of Sichuan Province were studied and the results showed the coefficient of variation(cv) of petiole length and the leaf radius were 43.9% and 27.54% respectively.The adult plants had a great difference in cv between their second-level stem,the third-level stem and the node segment length.For the 4 populations,the cv of second-level stem were 86.33%,91.46%,76.36% and 51.20% respectively;as the third-level stem,they were 81.8...
