Imiterere yimiti, imikorere nuburyo bukoreshwa bwa IAA 3-acide acetike

Uruhare rwaIAA 3-acide acetike

Ikoreshwa nkikura ryikimera itera kandi isesengura reagent. IAA 3-acide acetike ya indole nibindi bintu bya auxin nka 3-indoleacetaldehyde, IAA 3-acide acetike ya indole na acide acorbike ibaho mubisanzwe muri kamere. Ibibanziriza aside 3-indoleacetike ya biosynthesis mu bimera ni tripitofani. Igikorwa cyibanze cya auxin kiri mukugenzura imikurire yibihingwa. Ntabwo iteza imbere gukura gusa ahubwo ifite n'ingaruka zo kubuza gukura no gukora ingingo. Auxin ntabwo ibaho gusa mubwisanzure mu ngirabuzimafatizo, ariko kandi irashobora guhambirwa cyane na macromolecules yibinyabuzima nubundi bwoko bwa auxin. Hariho kandi auxin ishobora gukora inganda zifite ibintu byihariye, nka indole-acetylasparagine, indole-acetyl pentose acetate na indole-acetylglucose, nibindi.

Kurwego rwa selire, auxin irashobora gukangura igabana rya selile cambium; Shishikariza kurambura ingirabuzimafatizo z'ishami no kubuza imikurire y'uturemangingo; Teza imbere gutandukanya selile ya xylem na floem, koroshya imizi yibiti, kandi ugenzure morfogenezi ya callus.

Auxin igira uruhare kuva ingemwe kugeza gukura kwimbuto haba murwego rwibihingwa byose. Guhindura itara ritukura ribuza auxin mugucunga mesocotyl kuramba mu ngemwe; Iyo aside indoleacetike yimukiye kuruhande rwo hasi rwishami, geotropiya yishami ibaho. Iyo aside indoleacetike yimuriwe kuruhande rwigicucu cyishami, Phototropism yishami ibaho. Acide Indoleacetic itera kwiganza hejuru; Gutinda amababi ya senescence; Auxin ikoreshwa kumababi ibuza kumeneka, mugihe auxin ikoreshwa kumpera yegereyegere yatandukanijwe itera kumeneka. Auxin iteza imbere indabyo, itera iterambere ryimbuto zidahuje igitsina, kandi itinda kwera imbuto.

Uburyo bwo gukoresha bwaIAA 3-acide acetike

1. Kunywa

.

. Mubisanzwe, 100-1000mg / L ikoreshwa mukunyunyuza ibice. Kubwoko bukunda gushinga imizi, ikoreshwa ryibanze ryakoreshejwe. Kubinyabuzima bitari byoroshye gushinga imizi, koresha kwibanda hejuru gato. Igihe cyo gushiramo ni amasaha agera kuri 8 kugeza kuri 24, hamwe nibitekerezo byinshi hamwe nigihe gito cyo gushiramo.

2. Gutera

Kuri chrysanthemumu (munsi yamasaha 9 yumucyo wumucyo), gutera umuti wa 25-400mg / L rimwe birashobora kubuza kugaragara kumurabyo no gutinda kurabyo.
