摘要
目的分析披麻草野生居群表型多样性。方法对12个居群植株叶片长、叶片宽、叶片数、叶基长度、叶基直径等5个性状进行测量,并测定居群土壤pH值和肥力指标。所得数据采用Excel和SPSS(19.0)软件进行描述性、单因素方差和LSD多重比较处理分析。结果披麻草变异系数最大的为叶基直径,最小的为叶基长度;叶片长、叶片宽、叶片长/叶片宽、叶数、叶基长度、叶基直径各项性状在各居群间均有极显著性差异(P<0.01)。全盐量、有效磷及速效钾含量在居群间并无一定的规律可循,地上部分表型特征不能作为全盐量、有效磷和速效钾的直观性指标。结论披麻草居群间的环境差异及个体间的小环境差异对披麻草生长过程中的形态变化产生很大的影响。
Objective:To study the wild population phenotypic diversity of Veratrum taliense Loes.Methods:Five characters such as leaf length,leaf width,leaf number,leaf base length and leaf base diameter of 12 population plants were measured,and the pH value and fertility index of the population soil were determined.The data obtained were analyzed by using Excel and SPSS(19.0)software for description,one-way variance and LSD multiple comparisons.Results:The largest coefficient of variation of Veratrum taliense Loe was leaf basal diameter,and the smallest was leaf basal length,and the leaf length,leaf width,leaf length-width ratio,leaf number,leaf basal length and leaf basal diameter had extremely significant differences(P<0.01)among the populations.There is no certain rule for the total salt content,available phosphorus and available potassium content among the populations,and the aboveground phenotypic characteristics cannot be used as visual indicators of the total salt content,available phosphorus and available potassium.Conclusion:The environmental differences among the populations and the small environmental differences among individuals of Veratrum taliense Loe have a great influence on the morphological changes during the growth of Veratrum taliense Loe.
