Abstract

Aim . Study of the structure of intra‐ and interpopulation variability of Salvia canescens C.A. Mey. along an altitudinal gradient. Material and Methods . To study the morphological traits of Salvia canescens, a generative shoot was used as a «module». In four geographically isolated populations of the species, one generative shoot from 30 individuals was taken. 11 signs were taken into account on the shoots. Statistical analysis of the obtained data was carried out using the Statistica 5.5 program. The levels of variation were assessed according to G.M. Zaitsev. Results . The structure of intra‐ and interpopulation variability of S. canescens, a characteristic representative of mountain‐xerophyte vegetation and an endemic of the Greater Caucasus, was studied. According to the data obtained, the mean values of most of the studied traits of S. canescens increase with altitude. The variability of the studied traits of the species, both intra‐ and interpopulation, has an average and high levels. Most of the traits of S. canescens are positively correlated with each other at the p≤0.05 level. All traits, except for the number of internodes and leaves, are in a positive significant correlation (p≤0.001; p≤0.01) with height above sea level. The results of one‐way ANOVA and regression analyses showed significant differences between populations for most traits of the generative shoot. The maximum differentiation of populations was noted according to the traits «mass of stems» and «mass of inflorescences». Conclusions . The intra‐ and interpopulation variability of the morphological traits of Salvia canescens revealed along the altitudinal gradient is due to the ecological conditions of the species' habitat. The variability of the traits and the increase in the parameters of the generative sphere reflect the adaptation of the species along the altitudinal gradient.

俄罗斯达吉斯坦地区丹参(Lamiaceae)自然居群形态特征的变异
的目标。鼠尾草种群内和种群间变异结构的研究。沿高度梯度的材料和方法。为研究鼠尾草(Salvia canescens)的形态特征,以生芽为“模块”。在四个地理上孤立的种群中,从30个个体中采集了一个生殖芽。拍摄时考虑了11个迹象。使用Statistica 5.5程序对所得数据进行统计分析。变异程度是根据扎伊采夫的说法进行评估的。结果。本文研究了大高加索地区典型的山地旱生植物canescens的种群内和种群间变异结构。根据所获得的数据,所研究的黑松大部分性状的平均值随着海拔的升高而增加。所研究的物种性状在种群内和种群间的变异性均为平均和高水平。在p≤0.05水平上,黑松大部分性状之间呈显著正相关。除节间数和叶片数外,其余性状均呈显著正相关(p≤0.001;P≤0.01)。单因素方差分析和回归分析结果显示,种群间生殖芽的大部分性状存在显著差异。根据“茎质量”和“花序质量”的性状,可以观察到种群的最大分化。结论。鼠尾草(Salvia canescens)种群内和种群间形态特征在海拔梯度上的变异与生境的生态条件有关。这些性状的变异和生殖圈参数的增加反映了物种在海拔梯度上的适应性。
