0.03% S-abscisic acid (S-ABA) aqueous solution inogadzirisa kukura kwemupunga, inosimudzira kukura kwemidzi, inowedzera panicle uremu, uye inowedzera goho. Goho rakasimbiswa neruzhinji rinowedzera kubva pa7.8% kusvika 11.1%, paine mhedzisiro yakakosha inocherechedzwa pasi pemamiriro emunyu.
Maitiro Akakosha Ekuita
S-abscisic acid inozivikanwa se "growth-balancing factor" uye "stress-resistance inducing factor" yemupunga. Basa rayo guru rinoratidzwa nenzira mbiri:
Kukura Kwemitemo: Inodzikamisa endogenous hormone metabolism, inosimudzira kukura kwemidzi, inosimudzira kugona kwembeu kutora mvura nekudya, uye inosimudzira mbesa yakasimba. Iyo zvakare inoenzanisa kukura kwezvinomera uye kubereka, kusimudzira kuvandudzwa kwematiller anobereka uku ichideredza asingabereki.
Activation yeStress Resistance:Kuita senhume inokonzeresa kutaura kwekusagadzikana-kusagadzikana genes, inomisikidza immune system yemupunga yekushushikana-inopindura. Izvi zvinowedzera kushivirira pakusanaya kwemvura, tembiricha yakakwira, kutonhora, munyu, uye hosha, nekudaro kuderedza inhibition yekukura kunokonzerwa nenzvimbo dzakaipa uye kuve nechokwadi chegoho rakagadzikana.
Zvakananga Mhedzisiro dzeS-abscisic Acid paRice Roots uye Panicle Weight
Kukurudzira Kukudziridzwa kweMidzi: Kunyura kwembeu isati yadyarwa kunosimudzira kukura kwemidzi uye kunowedzera kugona kutora kudya. Izvi zvinopfupisa nguva yekudzikinura mushure mekudyara, zvichiita kuti madzinde apinde muchikamu chekukura nekukurumidza. Pasi pekunetseka kwemunyu, inochengetedza simba remidzi, zvichiita kuti irambe ichitora kudya kunovaka muviri.
Kuwedzera Panicle Weight uye Goho: Inovandudza chiyero chekuisa mbeu, inowedzera huremu hwe1,000-zviyo, inoderedza spikelet degeneration, uye inosimudzira kuzadza zviyo, zvinozotungamira kune goho rakakura. Ruzhinji rwekutsvagisa ruzivo runoratidza kuti pasi peyakajairika mamiriro ekurima, kushandiswa kweS-ABA pamupunga wehybrid kunogona kuwedzera goho ne7.8% -11.1%. Muminda ine munyu, inoderedza zvakanyanya mhedzisiro yemunyu pahuwandu hwepanicles inobereka uye chiyero chekuisa mbeu, nekudaro kuchengetedza kana kuwedzera goho-nekuwedzera kunopfuura 14% mune dzimwe nguva. Mirayiridzo yekushandisa S-abscisic acid (yekudzora kukura kwemupunga)
Ichi chigadzirwa chinonyanya kushandiswa kunyura mbeu yemupunga isati yadyarwa. Dhonza chigadzirwa kusvika ku1: 750-1: 1000 sezvakatsanangurwa, uye nyura mbeu panzvimbo yekushisa kwemaawa 24-36, kuve nechokwadi kuti chiyero chemvura chakakwana kuti chinyatsonyura. Mushure mekunyura, simbura mhodzi nemvura yakachena, wozoenderera mberi nemaitiro ekumera uye kudyara.
