Physiological Effect
Kurudzira kurebesa uye kukura kwemadzinde
Iyo inonyanya kukosha physiological mhedzisiro yegibberellinic acid (gibberellin) ndeyekusimudzira kukura kwechirimwa, kunyanya nekuti inogona kukurudzira sero kureba. GA kukura kwekusimudzira kune zvinotevera maitiro:
1. Kukurudzira kukura kwemiti yose, kurapwa kweGA kunogona kukurudzira zvakanyanya kukura kwemiti yemiti, kunyanya kune dwarf mutant marudzi, sezvakaratidzwa mumufananidzo 7-11. Nekudaro, GA yakanga isina mhedzisiro yakakosha pakurebesa kwezvikamu zvakasarudzika, nepo IAA yakave nemhedzisiro yakakura pakurebesa kweakazvimiririra stem seg. Chikonzero nei GA ichikurudzira kurebesa kwezvirimwa zvidiki ndezvekuti zviri muGA mumhando diki zvakaderera pane izvo zviri mumarudzi akajairwa nekuda kwekuvharirwa kweiyo endogenous GA synthesis.
2. Kusimudzira internode elongation GA inonyanya kuita pane iripo internode elongation, pane kukurudzira kuwedzera kwenhamba yemanodhi.
3. Hapana inhibition effect ye superoptimal concentration Kunyange kana iyo GA yakanyanya kukwirira, inogona kuramba ichiratidza huwandu hwekusimudzira hunoita, iyo yakasiyana zvikuru nemamiriro ezvinhu apo auxin inokurudzira kukura kwemiti nekugadzirisa kwakanyanya.
4. Mhinduro yemarudzi akasiyana-siyana emiti uye marudzi kune GA yakasiyana zvikuru. Goho repamusoro rinogona kuwanikwa nekushandisa GA pamiriwo (celery, lettuce, leek), uswa, tii, ramie nezvimwe zvirimwa.
Induced maruva
Kusiyanisa kwemaruva emaruva mune zvimwe zvirimwa zvepamusoro kunokonzerwa nehurefu hwezuva (photoperiod) uye tembiricha. Semuyenzaniso, biennials inoda imwe nhamba yemazuva ekudzikira tembiricha kurapwa (kureva, vernalization) kuti ruva, zvikasadaro anoratidza rosette kukura pasina bolting maruva. Kana GA ikaiswa kune izvi zvidyarwa zvisina kuvharwa, maruva anogona kuitiswa pasina yakaderera tembiricha maitiro, uye mhedzisiro yacho iri pachena. Pamusoro pezvo, GA inogonawo kukonzera kutumbuka kwezvimwe zvidyarwa zvemazuva-refu panzvimbo yezvirimwa zvemazuva mazhinji, asi GA haina kusimudzira mhedzisiro yekusiyanisa maruva emichero yemazuva mapfupi. Semuenzaniso, GA inogona kukurudzira kutumbuka kwe stevia, iron tree uye cypress uye fir miti.
Break dormancy
Kurapa mbatatisi dzakarara ne 2 ~ 3μg·g GA dzinogona kuita kuti dzimere nekukurumidza, kuitira kuti dzizadzise zvinodiwa nekudyara mbatatisi kakawanda pagore. Kune mhodzi dzinoda mwenje uye yakaderera tembiricha kuti imere, senge lettuce, fodya, Perilla, puramu nembeu dzeapuro, GA inogona kutsiva mwenje uye yakaderera tembiricha kuti iparadze dormancy, nekuti GA inogona kukonzeresa synthesis yealpha-amylase, protease uye mamwe mahydrolases, uye kukonzera kuparara kwezvinhu zvakachengetwa mumbeu yekukura nekukura kwe embryo. Muindasitiri yekugadzira doro, kurapa mhodzi dzebhari dzisina kumera neGA dzinogona kukonzeresa kugadzirwa kwea-amylase, kukurumidza kuita saccharification panguva yekubika, uye kuderedza kushandiswa kwekufema kwekumera, nekudaro kuderedza mitengo.
Kurudzira kusiyanisa kwemaruva echirume
Chiyero chemaruva echirume chakawedzera mushure meGA kurapwa kwemiti ine muti wakafanana. Madzimai dioecious zvinomera, kana zvichibatwa neGA, zvichabudisawo maruva echirume. Mhedzisiro yeGA mune izvi inopesana neye auxin uye ethylene.
Physiological Effect
GA inogonawo kusimbisa kuunganidza kweIAA pane zvinovaka muviri, kusimudzira kugadzika kwemichero uye parthenocarpy yezvimwe zvirimwa, uye kunonoka mashizha senescence. Mukuwedzera, GA inogonawo kukurudzira kupatsanurwa kwesero uye kusiyanisa, uye GA inosimudzira kupatsanurwa kwesero nekuda kwekupfupisa kweG1 uye S zvikamu. Zvisinei, GA inodzivisa kuumbwa kwemidzi yeadventitial, iyo yakasiyana neauxin.
Kushandisa nzira
1. Kurudzira kuumbwa kwemichero kana michero isina mhodzi. Mwaya magaka nemvura inokwana 50-100mg/kg kamwe chete panguva yekutumbuka kwemaruva kuti muchero ugadzirwe uye uwedzere goho. Mazuva 7-10 mushure mekutumbuka, mazambiringa anonhuwira akasimuka akapfapfaidzwa ne200-500mg/kg yemvura kamwe chete kukurudzira kuumbwa kwematombo asina michero.
2. Kurudzira kukura kwekudya kwecelery mavhiki maviri isati yakohwewa, pfapfaidza mashizha ne50-100mg/kg mushonga wemvura kamwe chete; Mwaya mashizha 1-2 nguva mavhiki matatu musati makohwewa kuti madzinde nemashizha akure.
3. Soak tubers ne 0.5-1mg/kg solution ye30min usati wadyara mbatatisi kuti aparadze dormancy uye kukurudzira kumera; Kunyika mhodzi ne1mg/kg yemushonga wemvura usati wadyarwa unogona kukurudzira kumera.
4. Anti-kuchembera uye fresh-cheping effect Garlic moss ine 50mg/kg mushonga wemishonga ye10-30min, citrus green fruit period ine 5-15mg/kg mushonga mushonga pfapfaidza muchero kamwe, banana mushure mekukohwa ne10mg/kg mushonga sora muchero, magaka, mavise-watermelon-50mg mushonga wemushonga/50mg yemishonga kutsva-kuchengeta maitiro.
5. Gadzirisa maruva echrysanthemum vernalization stage ne 1000mg/kg liquid spray leaves, cyclamen bud stage ine 1-5mg/kg liquid spray buds inogona kukurudzira maruva.
6. Kuvandudza huwandu hwembeu yekurimwa kwembeu yehybrid, inowanzotangwa pa15% yemusoro waamai, uye kurapwa ne25-55mg/kg mushonga wemvura kamwechete kana katatu panopera 25%. Shandisa low concentration kutanga, then high concentration.
Nyaya dzinoda kutarisirwa
1. Gibberellic acid haina kunyungudika mumvura, inonyunguduka nedoro shoma kana doro isati yashandiswa, uye inonatsa nemvura kusvika kune inodiwa.
2. Mbeu dzisina kuberekwa dzezvirimwa dzakabatwa ne gibberellic acid dzakawedzera, saka hazvina kukodzera kushandisa mushonga mukudyara minda.
