S-abscisic Acid inonyatso kumisa kushushikana-kupokana majini mumupunga, ichiwedzera zvakanyanya kushivirira kwayo mukusanaya kwemvura, kutonhora, uye salinity-alkalinity, uku ichikurudzira midzi yekuvandudza uye kuwedzera huwandu hweanoshanda tillers.
Ichiita se "stress-resistance inducer" muzvirimwa, chinhu ichi chinokonzeresa chirimwa chemupunga kudzivirira kushushikana kwemukati memuviri nekudzora kuenzana kwemahomoni endogenous. Pasi pekusanaya kwekusanaya kwemvura, S-abscisic Acid inokonzera kuvhara stomatal kuderedza kubuda kwemvura; panguva imwe chete, inosimudzira basa rema enzymes anodzivirira-senge superoxide dismutase uye catalase-kudzikamisa membrane lipid peroxidation kukuvara uye kuchengetedza photosynthetic chiitiko.
Munzvimbo dzakadzika-kupisa, inokonzera kusanganiswa kweprotein inotonhora uye inowedzera kugadzikana kwe membrane yesero, nokudaro kuderedza mazinga echlorosis uye pekugara kunokonzerwa nekukuvara kwechando.
Muvhu resaline-alkaline, S-abscisic Acid inoita kuti osmoregulation genes isimbise cellular osmotic kugadzirisa masimba, inovandudza zvakanyanya kukura kwesimba remupunga pasi pemamiriro emunyu.
Uyezve, S-abscisic Acid inosimudzira kuwedzera simba remidzi. Kurapa ne 0.5 mg/L kwakaratidzwa kuwedzera zvakanyanya simba remidzi mufodya; kana ikashandiswa zvakafanana kumupunga, inoratidza zvakafanana midzi-kusimudzira maitiro. Nezve mutemo wetiller, abscisic acid inoshanda zvakabatana ne strigolactones kudzvanya kuumbwa kwematiller asingashande uku ichikurudzira kuvandudzwa kwematiller anoshanda, nekudaro ichigonesa zvivakwa zvezvirimwa uye kuwedzera goho.
Mukushandisa, kunyura mbeu mumushonga we 0.3–0.4 mg/L kwemaawa 24 kusvika ku48 kunogona kuvandudza zvakanyanya kumera uye kunaka kwembesa; kupfapfaidza foliar panguva ye "shizha-uye-mumwe-moyo" kusvika "mashizha maviri-uye-mumwe-mwoyo" matanho anobatsira mukusimwa kwembesa uye inosimudzira kurima.
