I-S-abscisic Acid inokomeleza ngokubonakalayo ukuxhathisa kwengqolowa kwimbalela, kwizifo, nengqele, ngeli lixa ikwakhuthaza ukukhula kweengcambu okwesibini kunye nokwandisa inani lezixhobo zokuhlakula ezisebenzayo.
Isebenza njengesityalo "inducer-resistance inducer," le nto iyenza isebenze ngokukhawuleza ukubonakaliswa kofuzo lokuxhathisa uxinezeleko xa ingqolowa idibana nembalela, ubushushu obuphantsi, okanye uxinzelelo lwezifo. Ngaphantsi kweemeko zesomiso, i-abscisic acid ibangela ukuvalwa ngokukhawuleza kwe-stomata ukunciphisa ukuhamba kwamanzi; ngaxeshanye, iphakamisa ukubonakaliswa kwezakhi zofuzo ezifana ne-P5CS ukukhuthaza ukuqokelela kweproline kunye nokugcina ibhalansi ye-osmotic yeselula. Uphononongo lubonise ukuba ukusetyenziswa kwangaphandle kwe-S-abscisic Acid kwenza ukuba ingqolowa ikwazi ukugcina amanzi amagqabi aphezulu phantsi koxinzelelo lwembalela, oko konyusa impumelelo yephotosynthetic ngaphezulu kwe-26.9%.
Ukusetyenziswa kwe-Foliar ye-50-100 ppm S-abscisic Acid ngaphambi kokuvezwa kuxinzelelo oluphantsi lobushushu kunokubangela ukuhlanganiswa kweeprotheni ezichasayo ezibandayo kunye nokuphucula ukuqina kwe-membrane ye-lipid, ngaloo ndlela kuncitshiswe kakhulu amaxabiso e-chlorosis kunye nokufa kwezithole okubangelwa ngumonakalo womkhenkce. Ngaphaya koko, ngokuvula iindlela zokubonisa i-salicylic acid (SA) kunye ne-jasmonic acid (JA), i-abscisic acid ixhasa ukhuseleko lwenkqubo lwengqolowa, iphucula amandla ayo okuzikhusela kwizifo ezinje ngokubola kunye nokubola kweengcambu.
Ngokubhekiselele kulawulo lokukhula, ukugxininiswa okuphantsi kwe-abscisic acid (1-2 mg·kg⁻¹) kunokukhuthaza ukubunjwa kweengcambu zesibini kwingqolowa, ngaloo ndlela kuphuculwe amandla ayo okufumana amanzi kunye nokuthatha izondlo. Ukusetyenziswa kwe-Foliar ye-1–2 ppm S-abscisic Acid ngexesha lenqanaba lokuhlaza kukhuthaza ngokufanelekileyo ukuguqulwa kwamathayili, ukwandisa inani lee-tillers ezisebenzayo, kunye nokwandisa ubume bezityalo, ekugqibeleni kukhokelela kumazinga aphezulu okwenziwa kweendlebe kunye nokwanda kwezivuno.
Ekusetyenzisweni okusebenzayo, kuyacetyiswa ukuba kutshizwe nge-foliar 1–2 ppm S-abscisic Acid kwingqolowa yasebusika nokuba kuphambi kwenqanaba lokuluhlaza okanye ngexesha lokuqala lokuhlakula, uyigalele kabini ngezithuba zeentsuku ezisi-7; ngenye indlela, unyango olwenziwayo olune-50–100 ppm lunokusetyenziswa ngaphambi kokufika kwamaza abandayo ukomeleza ukuxhathisa koxinzelelo.
