叠氮化物、羟胺与氰化物已是公认的种子催芽剂。在大多数情况下,用化学催芽剂打破种子休眠时,常出现高活力种子,用化学催芽剂处理后,往往仍有一部分不能发芽,但调节催芽培养液的酸碱度,使 pH 达最适点时,可以得到最佳的催芽效果。还发现后熟不仅提高种子对化学催芽剂的敏感性,同时减弱催芽活性对 pH 的依赖性。又发现长时间在清水中吸涨的休眠种子对催芽剂的敏感性降 Azide, hydroxylamine and cyanide have been recognized as seed germination agents. In most cases, the use of chemical sprouting seeds to break dormancy, the seeds often appear high vigor, chemical sprouting agent treatment, often still can not germinate, but the regulation of the acidity of the germination culture medium, the pH of the most appropriate point , You can get the best germination effect. It has also been found that ripening not only increases the sensitivity of the seed to the chemical sprouting agent but also reduces the pH-dependent dependency of the germination activity. Also found that prolonged suction in the clear water dormant seeds on the sensitivity of the germination
