小麦种子发芽的适宜温度为20—25℃,而我省7、8月间的室内温度,一般为30—35℃。过去我们在大热天做小麦种子发芽试验,是找个阴凉的山洞,在山洞里发芽;或将种子播在阴湿的土壤中;或将种子埋在1尺左右深的地下发芽等。这些方法,有的限于条件,无法采用;有的只能使种子发芽率比一般方法所测的略高,并不能测出种子的真实发芽率。经过几年的摸索,我们试用简易控温法速测小麦种子发芽率,获得成功。
Wheat germination suitable temperature is 20-25 ℃, while in our province in July and August the room temperature, usually 30-35 ℃. In the past we did wheat seed germination tests on hot days to find shady caves that germinated in caves, sowed seeds in damp soil, or buried seeds in the ground at about 1 foot deep for germination. These methods, some limited conditions, can not be used; some can only make the seed germination rate slightly higher than the measured by the general method, and can not measure the true seed germination rate. After several years of exploration, we try the simple temperature control method of measuring the germination rate of wheat seeds, to be successful.
