S-abscisic acid nwere ike ime ka ọka wit na-eguzogide ụkọ mmiri ozuzo, ọrịa na oyi, ebe ọ na-akwalite mmepe mgbọrọgwụ nke abụọ yana ịbawanye ọnụ ọgụgụ ndị na-arụ ọrụ nke ọma.
Na-arụ ọrụ dị ka osisi "nrụgide-nguzogide inducer," ihe a na-eme ngwa ngwa na-eme ka ngosipụta nke mkpụrụ ndụ ihe nketa na-eguzogide nrụgide mgbe ọka wit zutere ụkọ mmiri ozuzo, obere okpomọkụ, ma ọ bụ nrụgide ọrịa. N'okpuru ọnọdụ ụkọ mmiri ozuzo, abscisic acid na-ebute mmechi ngwa ngwa nke stomata iji belata ntụgharị mmiri; n'otu oge, ọ na-akwalite okwu nke mkpụrụ ndụ ihe nketa dị ka P5CS iji kwalite mkpokọta proline ma nọgide na-enwe nguzozi osmotic cellular. Nnyocha e mere egosiwo na ngwa S-abscisic acid na-enyere ọka wit aka ịnọgide na-enwe mmiri akwụkwọ ndụ dị elu n'okpuru nrụgide ụkọ mmiri ozuzo, na-akwalite arụmọrụ photosynthetic site na 26.9%.
Ngwa foliar nke 50-100 ppm S-abscisic Acid tupu ikpughe na nrụgide dị ala nwere ike ime ka njikọ nke protein ndị na-eguzogide oyi ma kwalite nkwụsi ike nke lipid membrane, si otú a na-ebelata ọnụego chlorosis na ọnwụ mkpụrụ osisi kpatara site na mmebi oyi. Ọzọkwa, site n'ịgbalite ụzọ mgbaàmà nke salicylic acid (SA) na jasmonic acid (JA), abscisic acid na-akwado usoro mgbochi ọka wit, na-akwalite ikike nchebe ya megide ọrịa ndị dị ka blight na mgbọrọgwụ ire ere.
N'ihe gbasara nhazi uto, obere mkpokọta nke abscisic acid (1-2 mg·kg⁻¹) nwere ike ịkwalite nguzobe mgbọrọgwụ nke abụọ na ọka wit, si otú a na-eme ka ikike ya nweta mmiri na nri. Ngwa foliar nke 1-2 ppm S-abscisic Acid n'oge a na-acha akwụkwọ ndụ akwụkwọ ndụ na-akwalite ntụgharị nke tiller nke ọma, na-abawanye ọnụ ọgụgụ ndị na-arụ ọrụ nke ọma, ma na-eme ka nhazi ọnụ ọgụgụ nke osisi dịkwuo elu, n'ikpeazụ na-eduga n'ọnụ ọgụgụ ntị dị elu na ụbara mkpụrụ.
N'ime ngwa bara uru, a na-atụ aro ka ị fesa 1-2 ppm S-abscisic Acid na ọka wit oyi ma tupu oge agba akwụkwọ ndụ akwụkwọ ndụ ma ọ bụ n'oge ịmalite ịkụ mkpụrụ, na-etinye ya ugboro abụọ na etiti ụbọchị 7; N'aka nke ọzọ, a na-etinye usoro ọgwụgwọ nke nwere 50-100 ppm tupu ọbịbịa nke oyi oyi iji kwalite nguzogide nrụgide.
