Chemical properties
Pure product is white crystal, industry product is white powder.Mp 233 ~ 235 ℃.Inonyungudika mudoro, ketone, ester nemamwe organic solvents uye phosphoric acid buffer solution yepH 6.3, asi inonetsa kunyungudika muether, chloroform, benzene nemvura.Gadzira munyu Chemicalbook ne potassium uye sodium ions uye nyungudika mumvura.Gibberellin yakasimba inenge yakagadzikana, yakachengetwa kwenguva yakareba pasi pemamiriro akaoma uye akavharwa haazokundikani;Mushonga wemvura hauna kugadzikana, kuchengetedza kwenguva pfupi pane tembiricha yakaderera haizokundikane, kuderera kwekushisa kwakanyanya nekukurumidza;Asidhi kana kuti isina simba asidhi mamiriro akanyanya kugadzikana, alkaline mamiriro haana kugadzikana.
Plant hormone
Gibberellin imhando yemahomoni echirimwa ane alkane mhete chimiro chegibberellin, inogona kukurudzira kukura kwechirimwa.Inowanikwa mune zvese dissociative uye conjugated mafomu.Kune angangoita maviri kana anopfuura marudzi eGIBberellins mumiti, uye akasiyana gibberellins anogona kushandurudzwa kune mumwe nemumwe.Chemicalbook Mashizha, buds, midzi uye diki matishu embeu dzisati dzakura ndiwo makuru ekubatanidza nzvimbo dzeGIBberellin.Iine maitiro ehupenyu akadai sekusimudzira stem elongation, inducing lichen extraction uye maruva emiti yemazuva marefu pasi pemamiriro emazuva mapfupi, kuputsa dormancy, kukurudzira kuiswa kwemichero, parthenogenesis uye kupatsanurwa kwesero uye kusiyanisa.
use
Yakanyanya kushanda zvakanaka chirimwa kukura regulator.Inogona kukurudzira kukura nekukura kwezvirimwa, kukura kwekutanga, kuvandudza kunaka, kuwedzera goho;Inogona kukurumidza kuputsa dormancy yembeu, tubers uye bulbs uye kukurudzira kumera;Inogona kuderedza Chemicalbook shoma bud, ruva, boll, kurasikirwa muchero, kuwedzera michero yekumisikidza chiyero kana isina mhodzi kuumbwa.Inogona kushandiswa mupunga, gorosi, donje, miti yemichero, miriwo uye zvimwe zvirimwa, kukurudzira kukura kwayo, kumera, maruva, michero.
