S-abscisic Acid chinhu chakachena, chakangobva pachirimwa chinodzora kukura kwechirimwa chinokwanisa kukwidziridza kusanaya kwemvura uye kusamira zvakanaka kwechibage. Uyezve, inofambisa kuwedzera kwegoho nekugadzirisa kukura kwezvinomera, kuderedza kuisa nzeve, nekuvandudza kunaka kwezviyo.
Ichiita sechirimwa "stress-inducible factor," chinhu ichi chinokurumidza kumisa nzira dzechiratidzo dzeABA kana chibage chasangana nekusanaya kwemvura. Iyi activation inokonzeresa kuvharwa kwe stomatal kuderedza kubuda kwemvura panguva imwe chete ichisimudzira kudzika kwemidzi kupinza uye kuwedzera mvura yekukwira kwemvura. Ongororo dzinoratidza kuti kurapwa ne2–3 mg·kg⁻¹ kunogona kuwedzera kureba kwechirimwa, kureba kwemidzi, uye kuita catalase kwembeu dzechibage, nokudaro kusimbaradza hwaro hwehupenyu hwadzo hwekusanaya kwemvura.
Nezvekupokana kwekugara, iyo exogenous application yeS-abscisic Acid inhibits yakawandisa internode elongation muhunde, inosimudzira vascular bundle development, uye inovandudza stem mechanical simba. Maitiro ayo echiito anosanganisira kudzora chiyero pakati peendogenous gibberellins uye auxins, nekudaro kuwana inodiwa "kukura-inotonga" (anti-overgrowth) mhedzisiro. Uyezve, S-abscisic Acid inogadzirisa zvivakwa zvemiti nekudzikisa kureba kwekuiswa kwenzeve; izvi zvinoshandura pakati pechirimwa chegiravhiti pasi, zvichideredza zvakanyanya njodzi yekugara panguva yemhepo kana kunaya kwekunze.
Panyaya yekuvandudzwa kwemhando uye kukwidziridzwa kwegoho, S-abscisic Acid inoronga kuenzana pakati pekukura kwezvinomera uye kubereka, zvichifambisa kutamiswa kwezvigadzirwa zvephotosynthetic kuenda kuzviyo. Iyi nzira inotungamirira kukuwedzera kwehuwandu hwezviyo pahura uye huremu hwezviyo. Miedzo yemumunda yakaratidza kuti kushandisa zvine hungwaru kweS-abscisic Acid kunogona kuwedzera goho rechibage neinodarika 5%, ukuwo ichivandudza kukora kwezviyo nekuyera huremu, uye kuderedza kuitika kwekuumbwa.
Zvishandiso Zvinokurudzira:
Kupfekedza Mbeu/Kunyura: Kunyura mhodzi mune 0.3–0.5 mg/L S-abscisic Acid solution kwemaawa 6–12 kunogona kuvandudza kumera uye kuwedzera kusimba kwembesa.
Growth Regulation (Anti-overgrowth) at Seedling Stage: Foliar kushandiswa kwe1–2 ppm solution panguva yemashizha 6–8 kunogona kuvharira kurebesa kweinternode nekudzikisa kuiswa kwenzeve.
Nguva Dzakaoma Kushushikana-Kuramba: Isa mhinduro ye50-100 ppm kuburikidza nekupfapfaidza panguva yekubatana, kana mazuva matatu kusvika mashanu kusati kwaitika kusanaya kwemvura kana kuderera kwekushisa, kusimbisa simba rechirimwa rekudzivirira kusagadzikana.
