Gibberellic acide (Ga3) Gutongana imbuto no kumera
Shira imbuto mumazi ashyushye kuri 30 ℃ hanyuma ubashizwe kumasaha 6 ~ 10. Nyuma yo kuzikuramo, ubash n'amazi meza, hanyuma ubashizwemo aside 10 ~ 20 ppm gibbellic (Ga3) kumasaha 2 ~ 3, hanyuma wombike n'amazi meza. Mu bihe byubushyuhe buke, nko mumajyaruguru, imbuto zirashobora kuvurwa nubushyuhe bwumye (I.e., ku bushyuhe buke (0 ~ 5 ℃) Munsi yimyaka 30) kumasaha agera kuri 60.
Mu bihe by'ubushyuhe bwinshi, nko mu majyepfo, imbuto zirashobora gufatwa n'ubushyuhe butose (I.e., ku bushyuhe bwinshi (25 ~ 30 ℃) kuri 6 ~ 10). Nyuma yo kumurongo, imbuto zirashobora kwozwa n'amazi meza kandi yabibwe. Ubu buryo burashobora guteza imbere impinga yimbuto ziyongera imbuto, ongera igipimo cyo kumera, hamwe nigihe cyo kumera gucika intege.
Kugirango wirinde imbuto zituruka ku byangiritse cyane no kwandura kubera ubushyuhe buke mu gihe cyo gushiramo, fungicide (nka Carbendazim, Thiophana-Methyl, n'ibindi) birashobora kongerwaho mugihe cyo kwamagana kwanduza kwamanuka. Kuva gibberellic acide (ga3) ihujwe mumazi, Gibberellin irashobora gushonga mubintu byamarika (nka acetone, ethanone, nibindi) kugirango ukoreshe.
