不同温度、光照和覆土厚度对百里香种子萌发的影响

EFFECT OF DIFFERENT TEMPERATURE、IRRADIATION AND THICKNESS OF COVERING SOIL ON THE GERMINATION OF Thymus serpyllum L.var.asiaticus seeds

本文主要研究了在恒温15℃、20℃、25℃、30℃不同处理下,温度对百里香种子萌发的影响,以及15℃/20℃、20℃/25℃变温条件下百里香种子的萌发情况。并采用发芽率、发芽指数、活力指数、始发芽天数、发芽天数等指标对百里香种子发芽效果进行了评价。结果表明,随着温度从15℃升高到25℃,百里香种子发芽率、发芽指数、活力指数均上升。15℃~25℃是百里香的最适发芽温度区间,20℃/25℃是最适发芽温度条件。在不同光照情况下,25℃是最适发芽温度,16h光照/8h黑暗是百里香种子发芽的最佳光照条件,昼夜变温条件下更有利于百里香种子萌发。覆土厚度不应超高0.5 cm。储藏1 a的百里香种子发芽率可达86%,种子活力较高。

This article major studied under different constant temperature 15°C,20°C,25°C,30°C conditions,Thymus serpyllum L.var.asiaticus seed s germination,and under 15°C to 20°C,20°C to 25°C changing temperature conditions,Thymus serpyllum L.var.asiaticus seed s germination.And by using germination percentage,germination index,vitality index,the beginning germination days and germination days of Thymus serpyllum L.var.asiaticus,the results were evaluated.The results show that as the temperature increased from 15°C ...
