| 摘 要： | 为了研究土壤养分对蝴蝶花的花形态可塑性的影响，在田间实验中对蝴蝶花进行了高、中、低养分（N、P、K）水平处理。实验表明，随着土壤养分水平的增加，外轮花瓣长和宽、内轮花瓣长和宽、雌蕊长、雄蕊长、花冠直径均逐渐增加。花各组成部分的形态大小间相关性显著（P=0．05）。结合花部形态特征对环境异质性的生态适应意义，对实验结果进行了讨论。

| Abstract: | To study the influence of soil nutrient level on plasticity of floral characteristics in Iris japonica Thunb.,The experiment was carried out under high, medium,low levels of N,P,K. The experiment indicated that the length and width of outer petal, inner petal, the pistil and stamen length and the corolla diameter increased with the increase of soil nutrient level. Correlation between every two components of the flower was significant at 0. 05 level. The results were discussed in the context of adaptation of plants to environmental heterogeneity. |
