Sunta yar, ma jiro hadhaaga korriinka koritaanka dhirta cagaaran - calcium prohexadione

Prohexadione waa nooc cusub oo maamulaha koritaanka dhirta ee cyclohexane karboksilic acid.Waxaa si wadajir ah u sameeyay Japan Combination Chemical Industry Co., Ltd. iyo BASF ee Jarmalka.Waxay joojisaa biosynthesis ee gibberellin ee dhirta waxayna samaysaa dhirta Waxa ku jira gibberellin waa la dhimaa, taas oo dib u dhigaysa oo xakameynaysa koritaanka lugta ee dhirta.Inta badan loo isticmaalo dalagyada badarka, sida sarreenka, shaciga, iska caabinta hoyga bariiska, waxa kale oo loo isticmaali karaa lawska, ubaxa iyo cawska si loo xakameeyo korriimadooda.

1 Hordhaca Alaabta

Magaca guud ee Shiinaha: procyclonic acid calcium

Magaca guud ee Ingiriisiga: Prohexadione-calcium

Magaca isku dhafan: calcium 3-oxo-5-oxo-4-propionylcyclohex-3-enecarboxylate

Lambarka gelitaanka CAS: 127277-53-6

Qaaciddada molecular: C10H10CaO5

Cufnaanta molecular qaraabo: 250.3

Qaab-dhismeedka:

Qalabka jirka iyo kiimikaad: Muuqashada: budada cad;barta dhalaalka> 360 ℃;cadaadiska uumiga: 1.74×10-5 Pa (20 ℃);octanol/qaybinta qaybinta biyaha: Kow lgP=-2.90 (20℃);cufnaanta: 1.435 g/ml;Joogtada Henry: 1.92 × 10-5 Pa m3mol-1 (calc.).Solubility (20 ℃): 174 mg/L oo biyo nadiif ah;methanol 1.11 mg/L, acetone 0.038 mg/L, n-hexane 0.003 mg/l, toluene 0.004 mg/L, ethyl acetateXasilooni: heerkulka deggan ilaa 180 ℃;hydrolysis DT50 <5 d (pH=4, 20℃), 21d (pH7, 20℃), 89 d (pH9, 25℃);Biyaha dabiiciga ah, sawir-qaadista biyaha DT50 waa 6.3 d, sawir-qaadista DT50 ee biyaha la miiray waxay ahayd 2.7 d (29～34 ℃, 0.25W/m2).

Sumaynta: Daawada asalka ah ee prohexadione waa sunta sunta ah ee hooseeysa.LD50 afka degdega ah (lab/dheddig) ee jiirku waa>5,000 mg/kg, LD50 ba'an (lab/dheddig) ee jiirka waa>2,000 mg/kg, iyo LD50 afka ba'an ee jiirka (lab/dheddig) waa > 2,000 mg/kg.Sunta neefsashada LC50 (4 saac, lab/dheddig)> 4.21 mg/L.Isla mar ahaantaana, waxay ku yar tahay sunta noolaha deegaanka sida shimbiraha, kalluunka, boodada biyaha, algae, shinida, iyo gooryaanka dhulka.

Habka ficilka: Iyada oo faragelinaysa isku-dhafka gibberellic acid ee dhirta, waxay yaraynaysaa maadada gibberellic acid ee dhirta, waxay xakameysaa koritaanka lugta, kor u qaadka ubaxa iyo miraha, waxay kordhisaa dhalidda, horumarinta nidaamyada xididka, waxay ilaalisaa xuubabka unugyada iyo xuubabka organelle, waxayna hagaajisaa. iska caabin walaaca dalagga.Si loo joojiyo koritaanka daaqsinka ee qaybta sare ee geedka oo kor loogu qaado koritaanka taranka.

2 Diiwangelinta

Marka loo eego baaritaanka Shabakadda Macluumaadka Cayayaanka ee Shiinaha, laga bilaabo Janaayo 2022, wadarta 11 alaabada calcium prohexadione ayaa laga diiwaan geliyay dalkayga, oo ay ku jiraan 3 daawooyin farsamo ah iyo 8 diyaargarow, sida ku cad Shaxda 1.

3 Rajada suuqa

Xakamaynta koritaanka dhirta cagaaran, calcium prohexadione waxay la mid tahay maamulayaasha koritaanka dhirta ee paclobutrasol, niconazole iyo trinexapac-ethyl.Waxay joojisaa biosynthesis ee gibberellic acid ee dhirta, waxayna door ka ciyaartaa dalagyada dwarfing, Doorka xakameynta koritaanka dhirta.Si kastaba ha ahaatee, prohexadione-calcium ma laha hadhaaga dhirta, wax wasakh ah kuma laha deegaanka, iyo saameyn yar oo ku saabsan dalagyada soo socda iyo dhirta aan bartilmaameedka ahayn.Waxaa la dhihi karaa waxay leedahay rajo codsi oo aad u ballaaran.
