Chikhalidwe cha mankhwala, ntchito ndi njira zogwiritsira ntchito IAA 3-indole acetic acid

Udindo waIAA 3-indole acetic acid

Ntchito ngati chomera kukula stimulant ndi kusanthula reagent. IAA 3-indole acetic acid ndi zinthu zina za auxin monga 3-indoleacetaldehyde, IAA 3-indole acetic acid ndi ascorbic acid zilipo mwachilengedwe. Kalambulabwalo wa 3-indoleacetic acid wa biosynthesis muzomera ndi tryptophan. Ntchito yaikulu ya auxin ndiyo kulamulira kukula kwa zomera. Sizimangolimbikitsa kukula komanso zimakhala ndi zotsatira zolepheretsa kukula ndi mapangidwe a ziwalo. Auxin samangopezeka m'malo omasuka mkati mwa maselo a zomera, komanso amatha kukhala omangidwa ku macromolecules achilengedwe ndi mitundu ina ya auxin. Palinso auxin yomwe imatha kupanga ma complexes okhala ndi zinthu zapadera, monga indole-acetylasparagine, indole-acetyl pentose acetate ndi indole-acetylglucose, etc. Ichi chikhoza kukhala mawonekedwe osungiramo auxin mkati mwa maselo komanso njira yowonongeka kuti athetse poizoni wa auxin wochuluka.

Pa mlingo wa ma cell, auxin ikhoza kulimbikitsa kugawanika kwa maselo a cambium; Kulimbikitsa elongation wa nthambi maselo ndi ziletsa kukula kwa mizu maselo; Limbikitsani kusiyanitsa kwa ma cell a xylem ndi phloem, kuwongolera mizu ya cuttings, ndikuwongolera mofogenesis wa callus.

Auxin imagwira ntchito kuchokera ku mbande kupita ku kukhwima kwa zipatso pamagulu onse ndi mulingo wa mbewu zonse. Kuletsa kuwala kofiyira kosinthika kwa auxin pakuwongolera kutalika kwa mesocotyl mu mbande; Pamene indoleacetic acid imasamukira kumunsi kwa nthambi, geotropy ya nthambi imachitika. Pamene indoleacetic acid imasamutsidwa kumbali yamthunzi wa nthambi, phototropism ya nthambi imapezeka. Indoleacetic acid imayambitsa kulamulira kwakukulu; Kuchedwetsa kuphuka kwa masamba; Auxin yogwiritsidwa ntchito pamasamba imalepheretsa kukhetsa, pomwe auxin yomwe imagwiritsidwa ntchito kumapeto kwa gawo lopatukana imathandizira kukhetsa. Auxin imalimbikitsa maluwa, imapangitsa kukula kwa zipatso zosagwirizana ndi amuna kapena akazi okhaokha, ndikuchedwetsa kukhwima kwa zipatso.

Njira yogwiritsira ntchitoIAA 3-indole acetic acid

1. Kumira

(1) Nthawi yonse ya maluwa a tomato, maluwawo amawaviikidwa mu njira ya 3000 milligrams pa lita imodzi kuti apangitse parthenogenic fruiting ndi zipatso za tomato, kupanga zipatso za phwetekere zopanda mbewu ndikuwonjezera kuchuluka kwa zipatso.

(2) Kuyika mizu kumalimbikitsa kumera kwa mbewu monga maapulo, mapichesi, mapeyala, zipatso za citrus, mphesa, kiwis, sitiroberi, poinsythia, carnations, chrysanthemums, roses, magnolias, rhododendrons, zomera za tiyi, metasequoia glyptostroboides, ndi mizu kufulumizitsa kuchuluka kwa kubereka kwa vegetative. Nthawi zambiri, 100-1000mg/L amagwiritsidwa ntchito kuviika m'munsi mwa cuttings. Kwa mitundu yomwe imakonda kuzula, ndende yotsika imagwiritsidwa ntchito. Kwa zamoyo zomwe zimakhala zovuta kuzizula, gwiritsani ntchito ndende yokwera pang'ono. Nthawi yonyowa ndi pafupifupi maola 8 mpaka 24, ndikuyika kwambiri komanso nthawi yayitali yonyowa.

2. Kupopera mbewu mankhwalawa

Kwa chrysanthemums (pansi pa kuwala kwa maola 9), kupopera mbewu mankhwalawa 25-400mg/L kamodzi kungalepheretse kuoneka kwa maluwa ndikuchedwa kuphuka.
