Mawu Oyamba

Gibberellin GA3 ndiye wowongolera kukula kwa mbewu omwe amagwiritsidwa ntchito kwambiri pazaulimi, nkhalango ndi ulimi ku China.
Ntchito zakuthupi za gibberellin GA3 makamaka zikuphatikizapo: kusintha chiwerengero cha maluwa achikazi ndi achimuna mu mbewu zina, kulimbikitsa parthenocarpy, kufulumizitsa kukula kwa zipatso ndi kulimbikitsa chikhalidwe cha zipatso;Kusweka kwa mbeu, kumera msanga kwa mbeu, kufulumizitsa kutalika kwa tsinde ndi kutsetsereka kwa mbewu zina;Kukulitsa chigawo cha masamba ndikufulumizitsa kukula kwa nthambi zazing'ono kumathandizira kudzikundikira kwa metabolites mu phloem ndikuyambitsa cambium;Kuletsa kusasitsa ndi senescence, kuwongolera lateral bud dormancy ndi mapangidwe a tuber.

Kugwiritsa ntchito

2.1 Kuti zotsatira zake zikhale zotani?
Ntchito yodziwika kwambiri ya gibberellin ndikufulumizitsa kukula kwa maselo (gibberellin imatha kuchulukitsa zomwe zili mu auxin muzomera, ndipo auxin imayang'anira kukula kwa cell).Zimalimbikitsanso kugawanika kwa maselo.Itha kulimbikitsa kukula kwa cell (koma sizimayambitsa acidization ya khoma la cell).Kuphatikiza apo, gibberellin imatha kuletsa kusasitsa, lateral bud dormancy ndi kukalamba, Physiological function of tuber mapangidwe.
2.2 Zogwiritsidwa ntchito pa mbewu ziti?
Gibberellin ndi yoyenera kwa mbewu zotsatirazi: thonje, phwetekere, mbatata, mtengo wa zipatso, mpunga, tirigu, soya ndi fodya kulimbikitsa kukula, kumera, maluwa ndi fruiting;Itha kulimbikitsa kukula kwa zipatso, kusintha kuchuluka kwa mbeu, komanso kukhala ndi zokolola zambiri pa thonje, masamba, mavwende ndi zipatso, mpunga, feteleza wobiriwira, ndi zina zambiri.
2.3 Mlingo ndi kagwiritsidwe ntchito

Zolemba

1. gibberellic acid ndi yaying'ono m'madzi kusungunuka, sungunulani ndi mowa pang'ono kapena Baijiu musanagwiritse ntchito ndikuchepetsani ku ndende yomwe mukufuna.
2. Mbeu zosabala za mbewu zothiridwa ndi gibberellic acid zimachuluka, kotero sikoyenera kugwiritsa ntchito mankhwala m'munda wosungidwa.
