摘要

本研究对亚高山千里光的形态变异进行了研究。(菊科),位于中欧塔特拉山脉海拔950米的斜坡上,重点是花的分配模式。在20个地点采集的200株植物中测量了15个形态特征,然后使用线性混合效应模型通过海拔对结果进行建模。植物地上生物量和高度随着海拔的升高而稳步下降;然而,最显著的特征是花分配模式的高度变化。低海拔植物的较小花头数量较多,花朵总数较低,而高海拔植物的较大花头数量较少,花朵总数较多。因此,平均单株花量随着海拔的升高而显著增加。有趣的是,外舌状花的宽度也随着海拔的增加而显著增加,增加了花头总周长的填充度。本研究结果证实,海拔是亚高山S.subalpinus营养和花性状变异的重要生态梯度。随后讨论了观测到的变化的可能原因,包括非生物和生物因素随海拔梯度的变化影响。

Patterns of floral allocation along an elevation gradient: variation in Senecio subalpinus growing in the Tatra Mountains

This study examined the morphological variation in Senecio subalpinus W.D.J. Koch. (Asteraceae) along a 950-m elevation gradient in the Tatra Mountains, Central Europe, with emphasis on floral allocation patterns. Fifteen morphological traits were measured in 200 plants collected in the field from 20 sites then the findings were modelled by elevation using linear mixed-effects models. Plant aboveground biomass and height decreased steadily with increasing elevation; however, the most distinctive feature was the elevational shift in floral allocation patterns. Low-elevation plants had greater numbers of smaller flower heads with a lower overall number of flowers, while high-elevation plants had smaller numbers of bigger flower heads and a greater overall number of flowers. Accordingly, the mean individual flower mass increased significantly with increasing elevation. Interestingly, the width of the outer ligulate flowers also increased considerably with increasing elevation, increasing the fill of the overall circumference of the flower head. Results of this study confirmed that elevation is an important ecological gradient driving variation in vegetative and floral traits of S. subalpinus. Possible causes of the observed variations are subsequently discussed, including the varying effects of both abiotic and biotic factors with elevation gradients.
