Gibberellic acid (GA) inoita basa rakakosha mune dzakasiyana siyana dzemuviri maitiro ezvirimwa.Zvinokurudzira kupatsanurwa kwesero, kurebesa masero, kureba kwedzinde uye kukura kwe24.GA inokonzera kupatsanurwa kwesero uye kurebesa mupfuti apices uye meristems25.Kuchinja kweshizha kunosanganisirawo kuderera kwehunde, kukura kweshizha diki, uye ruvara rwegirinhi rwakajeka26.Zvidzidzo zvinoshandisa inhibitory kana stimulatory factors zvakaratidza kuti calcium ions kubva mukati mezvinyorwa zvinoshanda sechipiri vatumwa munzira yegibberellin inoratidzira mumhunga corolla27.HA inowedzera kureba kwechirimwa nekukurudzira kuumbwa kwema enzymes anokonzera kuzorora kwemadziro sero, senge XET kana XTH, inowedzera uye PME28.Izvi zvinoita kuti maseru akure sezvo sero madziro anozorora uye mvura ichipinda musero29.Kushandiswa kweGA7, GA3 uye GA4 kunogona kuwedzera hunde kureba30,31.Gibberellic acid inokonzeresa kureba kwedzinde muzvirimwa zvidiki, uye mumiti yerosette, GA inodzosa kukura kwemashizha uye kurebesa kweinternode32.Nekudaro, pamberi pedanho rekubereka, kureba kwehunde kunowedzera kusvika 4-5 nguva yehurefu hwayo hwepakutanga33.Maitiro eGA biosynthesis muzvirimwa anopfupikiswa muMufananidzo 9.
GA biosynthesis muzvirimwa uye mazinga e endogenous bioactive GA, schematic inomiririra zvirimwa (kurudyi) uye GA biosynthesis (kuruboshwe).Miseve ine ruvara rwemavara kuti ienderane nechimiro cheHA chinoratidzwa munzira yebiosynthetic;miseve yakatsvuka inoratidza yakadzikira mazinga eGC nekuda kwenzvimbo munzvimbo dzezvirimwa, uye miseve mitema inoratidza yakawedzera mazinga eGC.Muzvirimwa zvakawanda, zvakaita semupunga nemavise, GA yemukati inokwira kuzasi kana kuzasi kweshizha30.Zvakare, mimwe mishumo inoratidza kuti bioactive GA yemukati inodzikira semashizha akareba kubva pachigadziko34.Iwo chaiwo mazinga egibberellins mune idzi kesi haazivikanwe.
Kudyara kukura regulators zvakare kunokanganisa zvakanyanya huwandu uye nzvimbo yemashizha.Mhedzisiro yacho yakaratidza kuti kuwedzera kukwirisa kwezvinomera kukura regulator kwakakonzera kuwedzera kukuru munzvimbo yemashizha uye nhamba.Benzyladenine inonzi inowedzera calla mashizha ekugadzirwa15.Zvinoenderana nemhedzisiro yeongororo iyi, marapirwo ese akavandudza nzvimbo yeshizha uye nhamba.Gibberellic acid + benzyladenine ndiyo yaive yakanyanya kurapa uye yakakonzera huwandu hukuru uye nzvimbo yemashizha.Paunenge uchikura diki schefflera mumba, panogona kuve nekuwedzera kunoonekwa kwehuwandu hwemashizha.
GA3 kurapwa kwakawedzera internode kureba zvichienzaniswa benzyladenine (BA) kana pasina hormonal treatment.Mhedzisiro iyi ine musoro yakapihwa basa reGA mukusimudzira kukura7.Kukura kwetsinde kwakaratidzawo mhedzisiro yakafanana.Gibberellic acid yakawedzera kureba kwedzinde asi yakadzikira dhayamita.Nekudaro, kushandiswa kwakasanganiswa kweBA neGA3 kwakawedzera kureba kwehunde.Kuwedzera uku kwaive kwakakwira zvichienzaniswa nemiti inobatwa neBA kana isina hormone.Kunyange zvazvo gibberellic acid uye cytokinins (CK) inowanzokurudzira kukura kwechirimwa, mune dzimwe nguva dzine migumisiro yakasiyana pamaitiro akasiyana35.Semuenzaniso, kushamwaridzana kusina kunaka kwakaonekwa mukuwedzera kwe hypocotyl urefu mumiti inobatwa neGA uye BA36.Kune rimwe divi, BA yakawedzera midzi vhoriyamu (Tafura 1).Kuwedzera midzi nekuda kweExogenous BA yakashumwa mumiti yakawanda (semuenzaniso Dendrobium neOrchid marudzi)37,38.
Mishonga yose yehomoni yakawedzera nhamba yemashizha matsva.Kuwedzera kwechisikigo munzvimbo yeshizha uye kureba kwedzinde kuburikidza nemishonga yakasanganiswa kunodiwa nekutengesa.Nhamba yemashizha matsva chiratidzo chakakosha chekukura kwezvinomera.Iko kushandiswa kwemahomoni exogenous hakuna kushandiswa mukugadzirwa kwekutengesa kweLiriodendron tulipifera.Zvisinei, kukura-kukurudzira migumisiro yeGA neCK, inoshandiswa mukuenzanisa, inogona kupa ruzivo rutsva mukuvandudza kurimwa kwechirimwa ichi.Zvinoshamisa, iyo synergistic mhedzisiro yeBA + GA3 kurapwa yaive yakakwira kupfuura iyo yeGA kana BA inopihwa yega.Gibberellic acid inowedzera nhamba yemashizha matsva.Sezvo mashizha matsva achikura, kuwedzera huwandu hwemashizha matsva kunogona kuderedza kukura kwemashizha39.GA yakanzi inonatsiridza kutakurwa kwe sucrose kubva kunyura kuenda kune kunobva nhengo40,41.Uye zvakare, kushandiswa kwekunze kweGA kune zvinomera zvisingaperi zvinogona kusimudzira kukura kwenhengo dzezvinomera semashizha nemidzi, nekudaro kudzivirira shanduko yekukura kwezvinomera kusvika pakubereka42.
Mhedzisiro yeGA pakuwedzera chirimwa yakaoma nyaya inogona kutsanangurwa nekuwedzera kwe photosynthesis nekuda kwekuwedzera kweshizha nzvimbo43.GA inonzi yakakonzera kuwedzera kwemashizha eMaze34.Zvigumisiro zvakaratidza kuti kuwedzera kweBA ku200 mg / L kunogona kuwedzera urefu uye nhamba yematavi echipiri uye midzi yemidzi.Gibberellic acid inopesvedzera maitiro emasero akadai sekusimudzira kupatsanurwa kwesero uye kurebesa, nekudaro kunatsiridza kukura kwezvinomera43.Pamusoro pezvo, HA inowedzera mudhuri wesero nekuita hydrolyzing starch kuita shuga, nekudaro ichidzikisa mukana wemvura yesero, zvichiita kuti mvura ipinde muchitokisi uye pakupedzisira ichitungamira kusero elongation44.
