Abstract

LiCl inhibits the nyctinastic closure of folioles of excised leaves and enhances their opening, if there are 3 h before the light is switched off or on; the minimal concentration for significant effects on closure is 3·10(-4) M, and on opening 3·10(-3). The use of chlorides of other cations and other Li salts showed specificity of the lithium for the closure movement, the effect being reversed by KCl and NaCl. For the opening movement the Li effect is less specific. These results are compared to those obtained in other phenomena.

摘要

LiCl 抑制切叶闭合运动，如果在关灯或开灯前 3 小时给予，LiCl 会促进切叶的开放；对切叶闭合运动有显著影响的最小浓度为 3·10(-4) M，对切叶开放运动的最小浓度为 3·10(-3) M。其他阳离子的氯化物和其他 Li 盐的使用表明，Li 对闭合运动具有特异性，该效应可被 KCl 和 NaCl 逆转。而对于开放运动，Li 的作用则不那么特异。这些结果与在其他现象中获得的结果进行了比较。
