Imiterere y'imiti, imikorere n'uburyo bwo kuyikoresha ya aside asetiki ya IAA 3-indole

Uruhare rwaaside asetiki ya IAA 3-indole

Ikoreshwa nk'ikintu gitera imbaraga mu gukura kw'ibimera no kubisesengura. IAA 3-indole acetic aside n'ibindi bintu bya auxin nka 3-indoleacetaldehyde, IAA 3-indole acetic aside na aside ascorbic bibaho mu buryo busanzwe. Imbere ya aside 3-indoleacetic mu gukora biosynthesis mu bimera ni tryptophan. Akamaro k'ibanze ka auxin ni ukugenzura imikurire y'ibimera. Ntabwo itera imbere gusa ahubwo igira ingaruka zo kubuza imikurire no gushinga ingingo. Auxin ntabwo ibaho gusa mu ngirabuzimafatizo z'ibimera, ahubwo ishobora no guhuzwa cyane na macromolecules y'ibinyabuzima n'ubundi bwoko bwa auxin. Hariho kandi auxin ishobora gukora complexes hamwe n'ibintu byihariye, nka indole-acetylasparagine, indole-acetyl pentose acetate na indole-acetylglucose, nibindi. Ubu buryo bushobora kuba uburyo bwo kubika auxin mu ngirabuzimafatizo ndetse n'uburyo bwo gukuraho uburozi bwa auxin ikabije.

Ku rwego rw'uturemangingo, auxin ishobora gukurura igabanyuka ry'uturemangingo twa cambium; Itera imbaraga uburebure bw'uturemangingo tw'amashami no kubuza ikura ry'uturemangingo tw'imizi; Itera imbere itandukaniro ry'uturemangingo twa xylem na phloem, yoroshya imizi y'ibice, kandi ikagenzura imiterere ya callus.

Auxin igira uruhare kuva ku mbuto kugeza ku gukura kw'imbuto haba ku rwego rw'ingingo ndetse no ku gihingwa cyose. Kubuza auxin mu buryo bugaragara mu kugenzura uburebure bwa mesocotyl mu mbuto; Iyo aside indoleacetic yimutse ijya hasi ku ishami, imiterere y'ishami irahinduka. Iyo aside indoleacetic yimuwe ku ruhande rw'ishami rufite igicucu, ishami rihinduka phototropism. Aside indoleacetic itera imbaraga nyinshi; Itinda gusaza kw'amababi; Auxin ishyirwa ku mababi ibuza gushwanyuka, mu gihe auxin ishyirwa ku mpera y'urwego rwacitse itera gushwanyuka. Auxin itera indabo, itera iterambere ry'imbuto zidafite igitsina, kandi igatinda kwera kw'imbuto.

Uburyo bwo gukoreshaaside asetiki ya IAA 3-indole

1. Kuroba

(1) Mu gihe cyose cy’indabyo z’inyanya, indabyo zijugunywa mu gipimo cya miligarama 3000 kuri litiro kugira ngo inyanya zibyare imbuto ziturutse ku gice cy’imbuto, zigakora imbuto z’inyanya zidafite imbuto kandi zikongera umuvuduko w’imbuto.

(2) Gutera imizi mu bimera nka pome, peaches, pears, imbuto z'indimu, inzabibu, kiwis, strawberries, poinstythia, carnations, chrysanthemums, roza, magnolias, rhododendrons, icyayi, metasequoia glyptostroboides, na poplar, kandi bigatera ishingwa ry'imizi myiza, byihutisha umuvuduko wo kororoka kw'ibimera. Muri rusange, 100-1000mg/L ikoreshwa mu kuhira hasi ku biti. Ku moko akunda kubira imizi, hakoreshwa urugero ruto. Ku moko atoroshye kubira imizi, koresha urugero ruto. Igihe cyo kubira amazi ni amasaha 8 kugeza kuri 24, hamwe n'igihe gito cyo kubira amazi.

2. Gutera imiti

Ku bimera bya chrysanthemum (mu gihe cy'amasaha 9 y'urumuri), gutera umuti wa 25-400mg/L rimwe bishobora kubuza indabyo kugaragara no gutinda kurabya.
