摘要

对不同年份在托雷湖地区采集的麻黄标本材料的研究揭示了其花粉粒的形态变异性。花粉粒假珠心和柱状（脊）数量的发展与生长季节的温度和湿度值之间存在反比关系。在潮湿的季节，植物产生的花粉粒只有很少的假珠心。在干燥和凉爽的生长季节，假珠心的数量会增加。

Variability of Ephedra dahurica Turcz. Pollen as an Indicator of Humidity for the Modern Climate of Southeastern Transbaikalia

Abstract

The study of herbarium materials of the Ephedra dahurica Turcz. collected in the Torey Lakes region in different years has revealed the morphological variability of its pollen grains. An inverse relationship has been established between the development of the number of pseudosulci and plicae (ridge) of pollen grains and the values of temperature and humidity during the growing season. During wet seasons, the plant produces pollen grains with few pseudosulci. The number of pseudosulci increases during dry and cool growing seasons.
