Cov khoom siv tshuaj
Cov khoom ntshiab yog dawb siv lead ua, cov khoom lag luam yog cov hmoov dawb.Mp 233 ~ 235 ℃.Nws yog soluble hauv cawv, ketone, ester thiab lwm cov kuab tshuaj organic thiab phosphoric acid tsis haum cov tshuaj pH 6.3, tab sis nyuaj rau yaj hauv ether, chloroform, benzene thiab dej.Daim ntawv ntsev Chemicalbook nrog poov tshuaj thiab sodium ions thiab yaj hauv dej.Gibberellin cov khoom yog qhov ruaj khov, khaws cia rau lub sijhawm ntev hauv qhov chaw qhuav thiab kaw yuav tsis poob;Kev daws dej tsis ruaj khov, lub sij hawm luv luv cia ntawm qhov kub thiab txias yuav tsis poob, siab dua kub decomposition sai dua;Acidic los yog qaug zog acidic tej yam kev mob yog ruaj khov, alkaline tej yam kev mob tsis ruaj tsis khov.
Cov tshuaj hormones
Gibberellin yog ib hom nroj tsuag cov tshuaj hormones nrog lub alkane nplhaib qauv ntawm gibberellin, uas tuaj yeem txhawb kev loj hlob ntawm cov nroj tsuag.Nws muaj nyob rau hauv ob qho tib si dissociative thiab conjugated daim ntawv.Muaj tsawg kawg yog ob lossis ntau hom GIBberellins hauv cov nroj tsuag, thiab cov gibberellins sib txawv tuaj yeem hloov mus rau ib leeg.Chemicalbook Nplooj, buds, cov hauv paus hniav thiab cov ntaub so ntswg ntawm cov noob tsis paub tab yog lub ntsiab synthesis ntawm GIBberellin.Nws muaj cov teebmeem physiological xws li txhawb nqa qia elongation, inducing lichen extraction thiab flowering ntawm cov nroj tsuag ntev-hnub nyob rau hauv luv-hnub tej yam kev mob, rhuav dormancy, txhawb cov txiv hmab txiv ntoo teeb, parthenogenesis thiab cell division thiab sib txawv.
siv
Highly zoo cog kev loj hlob regulator.Muaj peev xwm txhawb cov qoob loo loj hlob thiab kev loj hlob, kev loj hlob ntxov, txhim kho zoo, nce yield;Nws tuaj yeem rhuav tshem cov dormancy ntawm cov noob, tubers thiab qhov muag teev thiab txhawb kev germination;Yuav txo tau Chemicalbook tsawg bud, paj, boll, txiv hmab txiv ntoo poob, nce txiv hmab txiv ntoo tus nqi los yog seedless txiv hmab txiv ntoo tsim.Yuav siv tau rau hauv nplej, nplej, paj rwb, txiv hmab txiv ntoo ntoo, zaub thiab lwm yam qoob loo, txhawb nws txoj kev loj hlob, germination, flowering, txiv hmab txiv ntoo.
Lub cev muaj zog
Molecular Luj: 346.4g / mol;Lub cev daim ntawv: Crystalline khoom.Melting point: 223-225ºC (decomp.);npo: 4.0;Solubility: Hauv dej 5 g / l (chav kub).Soluble hauv methanol, ethanol, acetone, thiab aqueous alkali;me ntsis soluble hauv diethyl ether thiab ethyl acetate.Insoluble hauv chloroform.Potassium, sodium, thiab ammonium ntsev: Yooj yim soluble nyob rau hauv dej (potassium ntsev 50; Stability: qhuav gibberellic acid yog ruaj khov nyob rau hauv chav tsev kub, tab sis maj mam undergoes hydrolysis nyob rau hauv aqueous los yog aqueous-alcoholic daws, DT50 (20ºC) c. 14 d (pH 3-4), 14 d (pH 7).
