实验室内进行了假俭草种子净度检验样品最低限量和发芽检验方法的研究,探讨了光照(以黑暗为对照)、温度(分别包括20℃恒温,15/25℃、20/30℃、20/35℃和25/35℃变温)和发芽床(分设纸上TP和砂中S)等因素对种子发芽的影响。结果表明:假俭草种子净度检验样品最低限量是3g,送验样最低量以及计数其它植物种子检验样品最低量均为30g;最佳萌发条件为20/30℃或20/35℃变温(16小时低温,8小时高温),高温时段设光照,和纸上(TP)发芽;发芽的初次和未次计数时间分别以第10天和第21天为宜;种子的幼苗发育可划分为单子叶植物子叶留土类型。
In the laboratory, the methods for determining the minimum grain size and germination of the centipede seed cleanliness test were studied. The effects of light (darkness), temperature (respectively 20 ℃, 15/25 ℃, 20/30 ℃, 20/35 ℃ and 25/35 ℃ temperature change) and germination bed (divided into paper on the TP and sand S) and other factors on the seed germination. The results showed that the minimum seedling size of the centipedegrass was 3g, the minimum amount of sample to be sent and the minimum amount of other plant seed samples were 30g. The best germination condition was 20/30 ℃ or 20/35 ℃ 16 hours low temperature, 8 hours high temperature), set the high temperature light, and the paper (TP) germination; germination of the first and un-counted time respectively on the 10th and 21st days is appropriate; seedling development can be divided into single Leaves leave the type of leaf cotyledons.
