Auxin na Gibberellin

Igenzura ryikura ryibimera muri rusange rigabanyijemo ibyiciro bitanu: auxins, gibberelline, cytokinine, aside abcisic na Ethylene. Uyu munsi ndavuga cyane cyane kumikorere ya auxin na gibberellin

(1) Auxin

Auxin mu bimera ikorwa cyane cyane mumashami mashya, amababi akiri mato no gukura insoro, kandi ifite ibiranga ubwikorezi bwa polar. Auxin igenzura umuvuduko wo kwaguka kwingirabuzimafatizo igira ingaruka ku gukomera kwurukuta rwakagari, igatera kurambura ingirabuzimafatizo, kandi iyo itwarwa hepfo kumurasa, irashobora gutuma igabanywa ryimikorere ya selile na stem cambium, kandi bikanabuza gukura kuruhande. amababi. iterambere, kandi rifite n'ingaruka zo gukumira gusaza. Auxin ikoreshwa cyane mugutezimbere imizi yo gutema ibiti byimbuto, kumera indabyo no kunaniza imbuto, kandi ikoreshwa cyane mukurinda kugabanuka kwimbuto mbere yo gusarura no kugenzura ko abahinzi bamera.

(2) Gibberellins

Gibberelline mu bimera ikorwa cyane cyane mumababi akiri mato, insoro zikiri nto n'imizi, kandi nta kiranga bigaragara cyo gutwara polar. Iyo gibberelline ishyizwe hanze kubiti byimbuto, kugenda kwayo nabyo ni bibi kandi imikorere yayo ifite aho igarukira. Igikorwa nyamukuru cya gibberellin ni: guteza imbere kuramba kwamashami mashya yibiti byimbuto, bityo bigatuma imikurire mishya ikura; guca ukubiri n'imbuto n'imbuto, guteza imbere kumera kw'imbuto n'imbuto; kubuza gushiraho indabyo no kugabanya indabyo; Koresha hamwe na vitamine kugirango wirinde imbuto zikiri nto kugwa no guteza imbere kwaguka kwimbuto. Byongeye kandi, gibberelline nayo igira ingaruka zo gutinda kwera imbuto.
