Konishi(1956)有系统地研究了生长素及其代谢作用对于植株开花形成和茎伸长的效应.从抽苔植株茎扦条的顶端至基部切割其韧皮部,其IAA或者NAA的运输总量比丛生植株的多.当植株在长日照状态时,其基部生长素的总量和生长索扩散的数量逐渐地增高.植株在长日照处理后不久,IAA氧化酶的活力下降.他断定,抽苔植株的生长和素含量比丛生植株的多,是由于减少了IAA氧化酶的活力.他还报道,大约在2个月内每天喷布IAA,诱导了丛生植株抽苔和花蕾形成.Liverman和Lang(1956)应用IAA处理在长光周期初期条件下的植株,也得到类似的结果,但植株开花的反应较弱.
Konishi (1956) systematically studied the effect of auxin and its metabolism on the flowering and stem elongation of plants.The total amount of IAA or NAA transport in the phloem was cut from the top of the bolting plant to the base of the bolting plant When the plants were in the state of long sunshine, the amount of auxin in their basal part and the number of their growth symbiosis gradually increased.The activity of IAA oxidase decreased after the plants were treated with long sunshine.He concluded that bolting Plant growth and content are much more than those in the cluster plant due to reduced IAA oxidase activity. He also reported that IAA was sprayed on a daily basis within about 2 months, inducing bolting and bud formation in tufted plants. Liverman and Lang (1956) The application of IAA to plants grown at the initial photoperiod stage also yielded similar results, but plants responded poorly to flowering.
