S-abscisic Acid imatha kukulitsa kukana kwa tirigu ku chilala, matenda, ndi kuzizira, pomwe imalimbikitsanso kukula kwa mizu yachiwiri ndikuwonjezera kuchuluka kwa tillerla.
Pochita ngati chomera "stress-resistance inducer," mankhwalawa amathandizira kuti majeremusi azitha kupirira kupsinjika pamene tirigu akumana ndi chilala, kutentha pang'ono, kapena kupsinjika kwa matenda. Pansi pa chilala, asidi abscisic imapangitsa kutsekedwa kofulumira kwa stomata kuchepetsa kutuluka kwa madzi; Panthawi imodzimodziyo, imayang'anira kufotokozera kwa majini monga P5CS kulimbikitsa kudzikundikira kwa proline ndikusunga ma cell osmotic balance. Kafukufuku wasonyeza kuti kugwiritsa ntchito kwakunja kwa S-abscisic Acid kumathandizira tirigu kukhalabe ndi madzi ochuluka a masamba pamavuto a chilala, kukulitsa mphamvu ya photosynthetic ndi 26.9%.
Kugwiritsa ntchito foliar kwa 50-100 ppm S-abscisic Acid musanayambe kupsinjika ndi kutentha pang'ono kungapangitse kaphatikizidwe ka mapuloteni osakanizidwa ndi kuzizira komanso kumapangitsa kuti khungu likhale lolimba la lipid, potero kuchepetsa kwambiri chiwerengero cha chlorosis ndi kufa kwa mbande chifukwa cha kuzizira kozizira. Kuonjezera apo, poyambitsa njira zowonetsera za salicylic acid (SA) ndi jasmonic acid (JA), abscisic acid imalimbitsa chitetezo cha mthupi cha tirigu, kumawonjezera mphamvu zake zodzitetezera kumatenda monga choipitsa ndi mizu yowola.
Ponena za malamulo a kukula, kuchepa kwa abscisic acid (1-2 mg·kg⁻¹) kungalimbikitse mapangidwe a mizu yachiwiri mu tirigu, potero kumawonjezera mphamvu yake ya madzi ndi zakudya zowonjezera. Kugwiritsa ntchito masamba kwa 1–2 ppm S-abscisic Acid pa nthawi yobiriwira kumalimbikitsa kutembenuka kwa tiller, kumawonjezera kuchuluka kwa mathila abwino, ndikukulitsa kuchuluka kwa mbewu, zomwe zimapangitsa kuti makutu apangidwe kwambiri komanso zokolola zambiri.
Pogwiritsira ntchito, tikulimbikitsidwa kupopera 1-2 ppm S-abscisic Acid pa tirigu wa dzinja kapena nthawi yolima kapena yolima, kuyika kawiri pakadutsa masiku 7; Kapenanso, chithandizo cham'mbuyo chokhala ndi 50-100 ppm chitha kugwiritsidwa ntchito chisanafike chimfine kuti chiwonjezere kupsinjika.
