不同温度条件下亚高山草甸野生牧草种子发芽率和发芽势的研究

GERMINATION RATE AND ABILITY OF WILD FORAGE SEEDS IN SUBALPINE MEADOW UNDER VARYING TEMPERATURE CONDITIONS

本文对分布在亚高山草甸地区的20种野生牧草种子在不同的温度条件下进行的发芽试验予以报道。根据发芽率、起始发芽前所需时间、发芽历期选择了各种牧草种子的最适发芽温度。

Germination rate of the seeds of nineteen species of wild forages which are distributed throughout the subalpine regions have been tested under varying temperature conditions. Based on germination rate, time needed before germination and experienced for germination of these seeds, the optimal temperature for germination of each species of the forages had been chosen.
