一、切胚法:将净度检验过的纯净种子,从中随机抽样数取4 00粒,重复四次,每次重复为1 00粒,浸泡软化(一般用60℃温水浸2小时)后,取出用双面刀片沿种沟纵切,使两片种子基本相等,然后将留下的半粒种子,切口向上,正齐排列于滤纸发芽床上,每床1 00片,加适宜的水,使种子与滤纸接触处有水膜出现为度,盖好盖置于室温下,一般经24小时后,即可得出发芽率。
First, the embryo cut method: The purity of the seeds have been tested, from which the number of random samples to take 4 00, repeated four times, each repeated for the 100, soaked softening (usually 60 degrees warm water immersion for 2 hours) Remove with a double-sided blade along the groin longitudinal cut, so that the two seeds are basically the same, and then leave half of the seeds, incision up, are aligned in the filter paper sprouting bed, bed 10000, add appropriate water, Seeds and filter paper contact at the water film appears as degrees, cover the lid placed at room temperature, generally after 24 hours, you can come to germination rate.
