Waxyaabaha kiimikada
Alaabta saafiga ah waa crystal cad, alaabta warshaduhu waa budo cad.Mp 233 ~ 235 ℃.Waxay ku milmi kartaa khamriga, ketone, ester iyo dareerayaasha kale ee organic iyo fosfooraska acid xal pH 6.3, laakiin way adagtahay in lagu milmo ether, chloroform, benzene iyo biyaha.Ku samee buug-kimiko cusbo leh potassium iyo ion sodium kuna milmi biyaha.Adag Gibberellin waa mid xasiloon, muddo dheer lagu kaydiyo xaaladaha qalalan iyo xaaladaha xiran ma guuldareysan doono;Xalka biyuhu waa mid aan degganayn, kaydinta muddada-gaaban ee heerkulka hooseeya ma fashilmi doono, heerkul sarreeya ayaa si dhakhso ah u burburaya;Xaaladaha acidic ama daciifka ah ayaa aad u deggan, xaaladaha alkaline waa kuwo aan degganeyn.
Hormoonka dhirta
Gibberellin waa nooc ka mid ah hormoonnada dhirta leh qaab dhismeedka giraanta alkane ee gibberellin, kaas oo kor u qaadi kara koritaanka dhirta.Waxay u jirtaa qaabab kala qaybsanaan iyo kuwo isku xidhan labadaba.Waxaa jira ugu yaraan laba ama in ka badan oo nooc oo GIBberellins ah oo ku jira dhirta, gibberellins kala duwan ayaa loo beddeli karaa midba midka kale.Caleenta Buuga Kiimikada, burooyinkeeda, xididdada iyo unugga da'da yar ee iniinaha aan qaan-gaarin ayaa ah meelaha ugu muhiimsan ee la isku qurxiyo ee GIBberellin.Waxay leedahay saameyn nafsi ah sida kor u qaadida elongation stem, soo saaridda lichen iyo ubaxa dhirta maalin-dheer ee xaaladaha maalin-gaaban, jebinta hurdada, kor u qaadida goob miro, parthenogenesis iyo qaybinta unugyada iyo kala duwanaanta.
isticmaal
Xakamaynta koritaanka dhirta oo aad waxtar u leh.Waxay kor u qaadi kartaa koritaanka dalagga iyo horumarka, qaan-gaarnimada hore, hagaajinta tayada, kordhinta wax-soo-saarka;Waxay si dhakhso ah u jebin kartaa hurdada abuurka, digriiga iyo nalalka waxayna kor u qaaddaa biqilka;Waxa uu yarayn karaa buug-yaraha Kiimikada buqaha, ubaxa, bollka, luminta miraha, kordhinta heerka dejinta midhaha ama samaynta miro-la'aanta.Waxaa loo isticmaali karaa bariiska, sarreenka, suufka, geedaha miraha, khudaarta iyo dalagyada kale, waxay kor u qaadaan koritaanka, biqilka, ubaxa, miraha
Guryaha Jirka
Miisaanka molecular:346.4g/mol;Qaab jireed:Crystalline adag.Barta dhalaalka: 223-225ºC (decomp.);pKa:4.0;Solubility: Biyaha dhexdiisa 5 g/l (heerkulka qolka).Ku milmay methanol, ethanol, acetone, iyo alkalis aqueous;wax yar oo ku milma diethyl ether iyo ethyl acetate.Aan lagu milmin chloroformPotassium, sodium, iyo ammonium cusbada: Si diyaar ah ugu milmay biyaha ( cusbada potassium 50; Xasilloonida: Gibberellic acid qalalan ayaa degan heerkulka qolka, laakiin si tartiib tartiib ah u mara hydrolysis ee xalal aqueous ama aqueous-alkolada, DT50 (20ºC) c. 14 d (pH). 3-4), 14d (pH 7).
