测定种子发芽率所用的种子,要从经过风选以后的种子中采1取,一般分为四组进行,以避免取样的误差。大粒种子每粗50粒,共200粒;小粒种子每组100粒,共400粒。根据种子的大小,选择适当的发芽器皿(发芽床),如在玻璃皿、菜碟里垫上纱布、脱脂棉、砂子、毛头纸等。这些用具要预先用开水消毒,避免在发芽试验中被杂菌感染。待冷凉后,将种子整齐地排列在上面, Seeds used to determine the germination rate of the seed, after the wind through the seed after mining 1 take, generally divided into four groups, to avoid sampling errors. Large seeds Each coarse 50, a total of 200; small seeds of 100 per group, a total of 400. According to the size of the seeds, select the appropriate germination vessels (germination bed), such as in glass dishes, dishes pad gauze, absorbent cotton, sand, feather paper. These utensils should be pre-disinfected with boiling water to avoid infection by miscellaneous bacteria in the germination test. To be cool, the seeds neatly arranged above,
