Basa reIAA 3-indole acetic acid
Inoshandiswa semushonga wekusimudzira kukura kwemiti uye wekuongorora. IAA 3-indole acetic acid nezvimwe zvinhu zveauxin zvakaita se3-indoleacetaldehyde, IAA 3-indole acetic acid uye ascorbic acid zviripo zvakasikwa. Chinhu chekutanga che3-indoleacetic acid yekugadzira zvinhu mumiti itryptophan. Basa guru reauxin riri mukudzora kukura kwemiti. Haingosimudziri kukura chete asiwo ine simba rekudzivisa kukura uye kuumbwa kwenhengo. Auxin haisipo chete mumahara mukati memasero emiti, asiwo inogona kusungirirwa zvakasimba kuma macromolecules ezvipenyu nemamwe marudzi eauxin. Kunewo auxin inogona kuumba macomplex ane zvinhu zvakakosha, zvakaita seindole-acetylasparagine, indole-acetyl pentose acetate uye indole-acetylglucose, nezvimwewo. Iyi ingave nzira yekuchengetedza auxin mukati memasero uye zvakare nzira yekubvisa chepfu yeauxin yakawandisa.
Padanho remasero, auxin inogona kukurudzira kupatsanurwa kwemasero ecambium; Kukurudzira kureba kwemasero ebazi uye kudzivirira kukura kwemasero emidzi; Kukurudzira kusiyana kwemasero exylem nephloem, kubatsira kudzika midzi kwezvidimbu, uye kudzora morphogenesis ye callus.
Auxin ine basa kubva pakukura kwembeu kusvika pakukura kwemichero panhengo nemuti wese. Kudziviswa kwe auxin nechiedza chitsvuku kunogona kudzoserwa mukudzora kurebeswa kwemesocotyl mumbeu; Kana indoleacetic acid ikatamira kudivi rezasi rebazi, geotropy yebazi inoitika. Kana indoleacetic acid ikaendeswa kudivi remumvuri rebazi, phototropism yebazi inoitika. Indoleacetic acid inokonzera kutonga kwepamusoro; Kunonoka kwemashizha; Auxin inoshandiswa pamashizha inodzivirira kudonha kwemashizha, nepo auxin inoshandiswa kumucheto wepedyo wechikamu chakaparadzaniswa ichikurudzira kudonha kwemashizha. Auxin inokurudzira kutumbuka kwemaruva, inokurudzira kukura kwemichero yemhando imwe chete, uye inononoka kuibva kwemichero.
Nzira yekushandisaIAA 3-indole acetic acid
1. Kunyikisa
(1) Munguva yakazara yemaruva ematomatisi, maruva anonyikwa mumusanganiswa we3000 milligrams pa litre kuti matomatisi abereke uye agadzire michero, zvichiita kuti michero yematomatisi isina mbeu iwedzere uye kuwedzera mwero wekukura kwemichero.
(2) Kunyikwa kwemidzi kunokurudzira midzi yezvirimwa zvakaita semaapuro, mapichisi, mapeya, michero yecitrus, mazambiringa, kiwis, mastrawberry, poinsythia, carnations, chrysanthemums, roses, magnolias, rhododendrons, tii plants, metasequoia glyptostroboides, uye poplar, uye kunokonzera kuumbwa kwemidzi inobatsira, zvichikurumidzisa mwero wekubereka kwezvirimwa. Kazhinji, 100-1000mg/L inoshandiswa kunyikwa pasi pezvidimbu. Kune mhando dzinokurumidza kunyikwa, huwandu hushoma hunoshandiswa. Kune mhando dzisingaremi kunyikwa, shandisa huwandu hwakanyanya. Nguva yekunyikwa inenge maawa masere kusvika makumi maviri nemana, nehuwandu hwakawanda uye nguva pfupi yekunyikwa.
2. Kupfapfaidza
Kune chrysanthemums (dziri pasi pechiedza chemaawa mapfumbamwe), kupfapfaidza mushonga we25-400mg/L kamwe chete kunogona kudzivirira kuoneka kwemabukira emaruva uye kunonoka kutumbuka kwemaruva.
