Dabeecadda kiimikada, hawlaha iyo hababka codsiga ee IAA 3-indole acetic acid

DoorkaIAA 3-indole acetic acid

Loo isticmaalo sidii kicinta koritaanka dhirta iyo reagent gorfaynta. IAA 3-indole acetic acid iyo walxaha kale ee auxin sida 3-indoleacetaldehyde, IAA 3-indole acetic acid iyo ascorbic acid ayaa si dabiici ah u jira. Horudhaca 3-indoleacetic acid ee biosynthesis ee dhirta waa tryptophan. Shaqada aasaasiga ah ee auxin waxay ku jirtaa nidaaminta koritaanka dhirta. Ma aha oo kaliya kor u qaadida korriinka laakiin sidoo kale waxay leedahay saameynta joojinta koritaanka iyo sameynta xubnaha. Auxin ma aha oo kaliya inay ka jirto xaalad xor ah gudaha unugyada dhirta, laakiin sidoo kale waxay si adag ugu xidhnaan kartaa makromolecules noolaha iyo noocyada kale ee auxin. Waxa kale oo jira auxin samayn kara dhismayaal leh walxo gaar ah, sida indole-acetylasparagine, indole-acetyl pentose acetate iyo indole-acetylglucose, iwm

Heerka gacanta, auxin wuxuu kicin karaa kala qaybinta unugyada cambium; Kicin kordhinta unugyada laanta oo joojiya koritaanka unugyada xididka; Kor u qaad kala soocidda unugyada xylem iyo phloem, fududeeyaan xididdada gooyn, iyo nidaaminta morphogenesis ee callus.

Auxin waxa ay door ka ciyaaraa min birta ilaa bislaanshaha miraha ee heerarka xubinta iyo dhammaan dhirta. Joojinta iftiinka cas ee dib-u-celinta ee auxin ee xakamaynta dhererka mesocotyl ee geedo; Marka indoleacetic acid u wareejiyo dhinaca hoose ee laanta, geotropy ee laanta ayaa dhacda. Marka indoleacetic acid loo wareejiyo dhinaca hadhsan ee laanta, phototropism ee laanta ayaa dhacda. Indoleacetic acid waxay keentaa awoodda sare; Dib-u-dhac abuurka caleen; Auxin lagu dabaqo caleemaha waxay joojisaa daadinta, halka auxin lagu dabaqo dhamaadka u dhow lakabka kala go'ay waxay kor u qaadaysaa daadinta. Auxin waxay kor u qaadaa ubaxa, waxay kicisaa horumarinta miraha aan jinsiga ahayn, waxayna dib u dhigtaa bislaanshaha miraha.

Habka isticmaalka eeIAA 3-indole acetic acid

1. Qooyi

(1) Inta lagu jiro xilliga ubaxa buuxa ee yaanyada, ubaxyada waxaa lagu qooyay xal 3000 milligaraam litirkiiba si ay u abuuraan miraha parthenogenic iyo goob midhaha yaanyada, samaynta midho yaanyo aan abuur lahayn iyo kordhinta heerka dejinta midhaha.

(2) Qooynta xididku waxay kor u qaadaa xididada dalagyada sida tufaaxa, fersken, isteroberi, miraha liinta, canabka, kiwis, strawberries, poinsythia, carnations, chrysanthemums, roses, magnolias, rhododendrons, dhirta shaaha, metasequoia glyptostroboides, iyo kobcinta xididdada soo koraya taranka dhirta. Guud ahaan, 100-1000mg/L ayaa loo isticmaalaa in lagu qooyo salka gooyn. Noocyada u nugul xididada, feejignaanta hoose ayaa loo isticmaalaa. Noocyada aan sahlanayn in la rujiyo, isticmaal feejignaan yar oo sarreeya. Wakhtiga qoolashadu waa qiyaastii 8 ilaa 24 saacadood, oo leh feejignaan sare iyo wakhti gaaban oo qooyn ah.

2. buufin

Chrysanthemums (ka hooseeya wareegga iftiinka 9-saac), ku buufinta xal 25-400mg / L hal mar waxay joojin kartaa muuqaalka burooyinkeeda ubaxa waxayna dib u dhigi kartaa ubax.
