摘要
通过发芽试验探讨温度、发芽床及光照等因素对扁穗雀麦Bromus cartharticus种子萌发的影响。试验设7种恒温(10、15、20、25、30、35和40℃)和2种变温(15/25℃,20/30℃)共9个处理;光照设黑暗(0)和光照(2000 1x)2个处理;发芽床设纸上(TP)、纸间(BP)、砂上(TS)和砂间(BS)4个处理。综合发芽率、发芽指数和活力指数,最后确定扁穗雀麦的最适发芽温度为25-30℃,发芽床选纸上发芽为好,对光照不敏感。
The influences of different temperatures, germinating beds and lights on the germination characteristics of Bromus cartharticus were discussed in germination test. The conditions of temperatures included seven constant temperatures (10,15, 20, 25, 30, 35 and 40 ℃) and two alternating temperatures (15/25 ℃ and 20/30 ℃), light treatments included darkness (0 1x) and 2 000 1x light intensity, and bed treatments were carried on the top of paper(TP), between of paper(BP), top of sand(TS) and between of sand(BS). The optimum seed germination temperature of B. cartharticus was 25-30℃, TP was the best bed and light insensitive.
