Abstract

Pea seedlings (cv. Alaska), were treated with two concentrations of (2-chloroethyl)trimethylammonium chloride (CCC) and choline chloride. Treatment with 1 mg/l CCC resulted in as much as a 150fold increase in endogenous gibberellin (GA) levels without there being any parallel stimulation of growth. Plants grown in 1,000 mg/l CCC were severely dwarfed but contained GA levels not significantly different from control plants grown in distilled water. CCC also retarded GA3-induced growth of pea seedlings. These effects appear to be CCC specific as the CCC analogue choline chloride affected neither the GA content of pea seedlings nor their response to GA3. The lack of correlation between endogenous GA levels and stem height suggests that in peas the predominant factor in CCC-induced inhibition of stem growth is not related to an effect of CCC on GA biosynthesis.

摘要

豌豆幼苗（品种 Alaska）用两种浓度的（2-氯乙基）三甲基氯化铵（CCC）和氯化胆碱处理。用 1mg/L CCC 处理可使内源赤霉素（GA）水平增加多达 150 倍，而没有任何平行的生长刺激。在 1000mg/L CCC 中生长的植物严重矮化，但 GA 水平与在蒸馏水中生长的对照植物没有显著差异。CCC 还延迟了 GA3 诱导的豌豆幼苗生长。这些影响似乎是 CCC 特异的，因为 CCC 类似物氯化胆碱既不影响豌豆幼苗的 GA 含量，也不影响它们对 GA3 的反应。内源 GA 水平与茎高之间缺乏相关性表明，在豌豆中，CCC 诱导的茎生长抑制的主要因素与 CCC 对 GA 生物合成的影响无关。
