Abstract

The inhibition of the growth of wheat seedlings by 2-chloroethyltrimethylammonium chloride (CCC) was strongly reduced by root application of acetylcholine (Ach). Ach was applied after uptake of CCC by the roots or by the leaves. Ach also stimulated growth of non-CCC-treated seedlings up to 30% when applied to the roots. Growth stimulation appeared to be dependent on pH of the medium and most effective at pH 4.5 and 6. At pH 7.5 Ach did not promote growth of wheat seedlings.

摘要

2-氯乙基三甲基氯化铵（CCC）对小麦幼苗生长的抑制作用，可被根系施用以乙酰胆碱（Ach）强烈削弱。Ach 可以在 CCC 被根系或叶片吸收后被施用。Ach 也可以刺激未经 CCC 处理的幼苗生长，根系施用时最高可达 30%。生长刺激似乎依赖于培养基的 pH 值，在 pH 值为 4.5 和 6 时效果最明显。在 pH 值为 7.5 时，Ach 不会促进小麦幼苗的生长。
