Plant kukura regulator: S-abscisic acid
S-abscisic acid ine physiological mhedzisiro yakadai sekukonzera bud dormancy, kudonha kwemashizha uye kuvharidzira kukura kwesero, uye inozivikanwawo se "dormant hormone".
Yakawanikwa muna 1960 uye yakatumidzwa zvisizvo nekuti yaive nechokuita nekudonha kwemashizha emiti. Zvisinei, zvino yava kuzivikanwa kuti kudonha kwemashizha emiti nemichero kunokonzerwa ne ethylene.
S-abscisic acid chigadzirwa chakasvibirira chakasvibirira,S-abscisic asidhi chisikwa chinokura chirimwa chinoshanda.
Ichi chinhu chakasikwa chinowanikwa mumiti. Izvo zvakasikwa zviri mumichero, miriwo uye zviyo zvinodyiwa nevanhu uye zvakachengeteka kuvanhu uye zvakatipoteredza.
Izvo zvigadzirwa zvinoshandiswa mukugadzira maitiro eabscisic acid tekinoroji zvese zvisina muchetura uye zvisingakuvadze zvekurima uye parutivi zvigadzirwa. Inowanikwa kuburikidza nekuvirisa hutachiona, pasina kuwedzera kwezvinhu zvinokuvadza kana zvinhu, uye hapana chepfu muchimiro chayo chemakemikari.
Kushandiswa kweS-abscisic acid
1.S-abscisic acid inhibitor inoshanda yekumera kwembeu
S-abscisic acid inogona kushandiswa kuchengetedza mbeu nekuchengetedza kumera.
2. S-abscisic acid inogona kukurudzira kuunganidzwa kwezvinhu zvekuchengetedza mumbeu nemichero, kunyanya kuunganidza mapuroteni ekuchengetedza uye shuga.
Kushandisa abscisic acid mumatanho ekutanga embeu nekukura kwemichero kunogona kuzadzisa chinangwa chekuwedzera goho rezvirimwa zvezviyo nemiti yemichero.
3. S-abscisic acid inogona kuwedzera kutonhora uye kutonhora kwemiti.
S-abscisic acid inogona kushandiswa kubatsira zvirimwa kuramba tembiricha yakaderera uye kukuvadzwa kwechando mukutanga kwechirimo uye kurima mbesa dzembesa dzine chando chakasimba.
4. S-abscisic acid inogona kuvandudza kusanaya kwemvura uye munyu-alkali kushivirira kwemiti.
S-abscisic acid ine kukosha kwakanyanya kwekushandisa mukubatsira vanhu kuramba kusanaya kwemvura kwakawanda, kugadzira nekushandisa minda yepakati uye ine goho rakaderera, uye kudyara masango.
5. S-abscisic acid ndiyo yakasimba kukura inhibitor.
S-abscisic acid inogona kutadzisa kukura kwezvirimwa zvese kana nhengo dzakasarudzika. Mhedzisiro yeABA pakukura kwechirimwa inopesana neiyo yeIAA, GA, uye CTK, uye inodzivirira kupatsanurwa kwesero uye kurebesa. Inhibit kurebesa uye kukura kwenhengo dzakadai sebud sheaths, matavi, midzi, uye hypocotyls.
6. Kushandiswa kweS-abscisic acid mumaruva emubindu
Sezvo S-abscisic acid (ABA) inogona kukurumidza kuvhara mapores makuru emashizha, inogona kushandiswa kuchengetedza maruva, kuwedzera nguva yemaruva (musimboti wekuchengetedza maruva), kutonga nguva yemaruva, uye kukurudzira midzi (horticultural regulation).
Maitiro ekushandisa S-abscisic asidhi musanganiswa
1. S-abscisic acid + auxin
Kunyanya kukurudzira kudzika midzi uye kusadyara mbeu mushure mekudyara madzinde, kana seedling cuttings, nezvimwe.
2. Ethylhexyl + S-abscisic acid, S-abscisic acid + gibberellin
Basa racho nderekudzora kukura kwakasimba uye kuwedzera chiyero chekuisa michero.
3. Anti-agonist + S-abscisic acid
Wedzera kunwisa kwezvinovaka muviri, kusimudzira kukura kwembesa, kuwedzera huwandu hwese hwezvinhu zvakaoma, uye kunatsiridza kusatonhora, kusanaya kwemvura, kusabatwa nezvirwere, uye kudzivirira kwezvipembenene.
Yakawanikwa muna 1960 uye yakatumidzwa zvisizvo nekuti yaive nechokuita nekudonha kwemashizha emiti. Zvisinei, zvino yava kuzivikanwa kuti kudonha kwemashizha emiti nemichero kunokonzerwa ne ethylene.
S-abscisic acid chigadzirwa chakasvibirira chakasvibirira,S-abscisic asidhi chisikwa chinokura chirimwa chinoshanda.
Ichi chinhu chakasikwa chinowanikwa mumiti. Izvo zvakasikwa zviri mumichero, miriwo uye zviyo zvinodyiwa nevanhu uye zvakachengeteka kuvanhu uye zvakatipoteredza.
Izvo zvigadzirwa zvinoshandiswa mukugadzira maitiro eabscisic acid tekinoroji zvese zvisina muchetura uye zvisingakuvadze zvekurima uye parutivi zvigadzirwa. Inowanikwa kuburikidza nekuvirisa hutachiona, pasina kuwedzera kwezvinhu zvinokuvadza kana zvinhu, uye hapana chepfu muchimiro chayo chemakemikari.
