Acide S-abscisic Acide nikintu cyiza, gisanzwe gikomoka kumikurire yikimera gishobora kuzamura neza amapfa no kurwanya ibigori. Byongeye kandi, byoroshya kongera umusaruro muguhuza imikurire y’ibimera, kugabanya ugutwi, no kuzamura ubwiza bw’ingano.
Gukora nk'igihingwa "ibintu bidashobora guhangayikishwa," iyi ngingo ikora byihuse inzira yerekana ibimenyetso byerekana ABA mugihe ibigori bihuye nibibazo byamapfa. Iyi activation itera gufunga stomatal kugirango igabanye amazi mugihe kimwe icyarimwe iteza imbere imizi yimbitse kandi ikongerera ubushobozi bwo gufata amazi. Ubushakashatsi bwerekana ko kuvura hamwe na 2-3 mg · kg⁻¹ bishobora kongera cyane uburebure bwigihingwa, uburebure bwumuzi, hamwe nigikorwa cya catalase cyibiti by ibigori, bityo bigashimangira urufatiro rwabo rwo kurwanya amapfa.
Kubijyanye no kurwanya amacumbi, ikoreshwa rya Acide ya S-abscisic Acide irabuza kurambura interode ikabije kuruti, byongera imikurire yimitsi, kandi bitezimbere imbaraga zumukanishi. Uburyo bwibikorwa bukubiyemo kugenzura uburinganire hagati ya gibberelline ya endogenous na auxins, bityo bikagera ku ngaruka zifuzwa "gukura-kugenzura" (kurwanya-gukura). Byongeye kandi, S-abscisic Acide itezimbere ubwubatsi bwibimera mukugabanya uburebure bwamatwi; ibi bihindura hagati yikimera gikurura imbaraga, bikagabanya cyane ibyago byo gucumbika mugihe cyumuyaga cyangwa imvura.
Mu rwego rwo kuzamura ireme no kongera umusaruro, Acide S-abscisic ihuza uburinganire hagati yo gukura kw’ibimera n’imyororokere, byorohereza guhinduranya ibicuruzwa bya fotosintetike ku ngano. Iyi nzira iganisha ku kwiyongera k'umubare w'ingano ku gutwi n'uburemere bw'igihumbi igihumbi. Ibigeragezo byo mu murima byagaragaje ko gukoresha Acide S-abscisic Acide bishobora kongera umusaruro wibigori hejuru ya 5%, mugihe kandi bizamura ingano nuburemere bwibizamini, kandi bikagabanya kwandura.
Ibyifuzo bifatika byo gusaba:
Kwambara Imbuto / Kunyunyuza: Kunyunyuza imbuto muri mg 0.3–0.5 mg / L S-abscisic Acide ya Acide mumasaha 6-12 birashobora kunoza igipimo cyo kumera no kongera imbaraga zo kurwanya ingemwe.
Amabwiriza yo Gukura (Anti-overgrowth) kuri Stage yo gutera: Gukoresha amababi yumuti wa 1-2 ppm mugihe cyibabi rya 6-8 birashobora kubuza neza kurambura internode no kugabanya ugutwi.
Ibihe bikomeye-Kurwanya Ibihe: Koresha igisubizo cya 50-100 ppm ukoresheje gutera mugihe cyo guhuriza hamwe, cyangwa iminsi 3-5 mbere y’amapfa ateganijwe cyangwa ibihe by'ubushyuhe buke, kugirango bongere imbaraga muri rusange.
