S-abscisic Acid tuaj yeem txhim kho cov qoob loo tiv thaiv kom qhuav, kab mob, thiab mob khaub thuas, thaum tseem txhawb nqa kev loj hlob hauv paus hauv paus thiab ua kom cov qoob loo zoo.
Ua raws li cov nroj tsuag "kev ntxhov siab-tiv taus inducer," cov tshuaj no sai sai ua rau kev nthuav qhia ntawm endogenous stress-resistance genes thaum nplej ntsib drought, tsis kub, los yog kab mob kev nyuaj siab. Nyob rau hauv drought tej yam kev mob, abscisic acid induces ceev ceev kaw ntawm stomata kom txo tau dej transpiration; ib txhij, nws upregulates cov kev qhia ntawm noob xws li P5CS los txhawb proline tsub zuj zuj thiab tswj cellular osmotic tshuav nyiaj li cas. Cov kev tshawb fawb pom tau hais tias exogenous daim ntawv thov ntawm S-abscisic Acid ua rau cov nplej kom tswj tau cov nplooj ntoos dej ntau dua nyob rau hauv kev ntxhov siab, ua kom cov photosynthetic efficiency ntau dua 26.9%.
Foliar daim ntawv thov ntawm 50-100 ppm S-abscisic Acid ua ntej raug rau qhov kub thiab txias kev ntxhov siab tuaj yeem ua rau cov synthesis ntawm txias-tiv taus proteins thiab txhim kho daim nyias nyias lipid stability, yog li txo tus nqi ntawm chlorosis thiab yub tuag los ntawm kev puas tsuaj. Tsis tas li ntawd, los ntawm kev ua kom pom txoj hauv kev ntawm salicylic acid (SA) thiab jasmonic acid (JA), abscisic acid bolsters nplej lub cev tiv thaiv kab mob, txhim kho nws lub peev xwm tiv thaiv kab mob xws li blight thiab hauv paus rot.
Nyob rau hauv cov nqe lus ntawm kev loj hlob txoj cai, tsawg concentration ntawm abscisic acid (1-2 mg·kg⁻¹) tuaj yeem txhawb kev tsim cov hauv paus hauv paus hauv cov nplej, yog li txhim kho nws lub peev xwm rau dej thiab cov khoom noj khoom haus. Foliar daim ntawv thov ntawm 1-2 ppm S-abscisic Acid thaum lub sij hawm ntsuab-up theem zoo txhawb tiller hloov dua siab tshiab, nce tus naj npawb ntawm cov tillers zoo, thiab optimizes cov nroj tsuag pej xeem qauv, thaum kawg ua rau siab dua pob ntseg-tsim tus nqi thiab nce yields.
Nyob rau hauv daim ntawv thov, nws raug pom zoo kom foliar tshuaj tsuag 1-2 ppm S-abscisic Acid rau lub caij ntuj no hom qoob mog ua ntej lub ntsuab-up theem los yog thaum ntxov tillering theem, thov nws ob zaug ntawm 7-hnub intervals; Tsis tas li ntawd, kev kho mob preemptive nrog 50-100 ppm tuaj yeem siv ua ntej tuaj txog ntawm nthwv dej txias los txhim kho kev ntxhov siab.
