Intangiriro n'imikorere ya Plant auxin
Auxin ni indole-3-acide acide, hamwe na molekile ya C10H9NO2. Numusemburo wambere wavumbuwe kugirango uteze imbere imikurire. Ijambo ry'icyongereza rikomoka ku ijambo ry'Ikigereki auxein (gukura).
Ibicuruzwa byiza bya acide indole-3-acetike ni kirisiti yera kandi ntishobora gushonga mumazi. Byoroshye gushonga mumashanyarazi kama nka Ethanol na ether. Ihindurwamo byoroshye kandi ihinduka roza itukura munsi yumucyo, kandi ibikorwa byumubiri nabyo biragabanuka. Indole-3-acide acide mu bimera irashobora kuba muburyo bwubuntu cyangwa muburyo buboshye. Iyanyuma ni ester cyangwa peptide.
Ibigize aside irike-3-acetike yubusa mu bimera ni bike cyane, hafi microgramo 1-100 kuri kilo yuburemere bushya. Biratandukanye bitewe nahantu hamwe nubwoko bwinyama. Ibiri mubice bikura cyane mubice cyangwa ingingo nkikura ryimyanya ndangagitsina ni bike.
Auxins nyinshi yibimera nayo igira uruhare mukugabana selile no gutandukanya, gukura imbuto, gushinga imizi mugihe ufata ibiti na defoliation. Ibyingenzi bisanzwe mubisanzwe auxin ni β-indole-3-acide acide. Gukora ibihimbano bikura byikura ryibihingwa bifite ingaruka zisa zirimo brassinolide, cytokinin, gibberellin, acide acetike ya Naphthalene (NAA), DA-6, nibindi.
Uruhare rwa Auxin ni ebyiri: irashobora guteza imbere gukura no kubuza gukura;
irashobora kwihuta no kubuza kumera; irashobora gukumira indabyo n'imbuto gutonyanga n'indabyo zoroshye n'imbuto. Ibi bifitanye isano no kwiyumvisha ubukana bwa Auxin kubice bitandukanye byigihingwa. Muri rusange, imizi yibihingwa irumva cyane kuruta imizi. Dicotyledon irumva cyane kuruta monocots. Kubwibyo, ibigereranyo bya auxin nka 2-4D birashobora gukoreshwa nkibimera. Irangwa na kamere yayo yimpande ebyiri, zishobora guteza imbere gukura, kubuza gukura, ndetse no kwica ibimera.
Ingaruka itera Auxin igaragara cyane mubice bibiri: kuzamurwa no kubuzwa:
Auxin ifite ingaruka zo kuzamura:
1. Imiterere yindabyo zumugore
2. Parthenocarpy, gukura k'urukuta rw'intanga
3. Itandukaniro ryimitsi iva mumitsi
4. Kwagura amababi, gushinga imizi kuruhande
5. Gukura kwimbuto n'imbuto, gukira ibikomere
6. Kwigenga bisanzwe, nibindi
Auxin ifite ingaruka zo kubuza:
1. Gusiba indabyo,
2. Gusiba imbuto, gukuramo amababi akiri mato, gukura kw'ishami kuruhande,
3. Gushinga imizi, nibindi.
Ingaruka ya auxin kumikurire yikimera biterwa nubunini bwa auxin, ubwoko bwibimera, nigihingwa. bijyanye n'ingingo (imizi, uruti, amababi, nibindi). Muri rusange, kwibanda cyane birashobora guteza imbere imikurire, mugihe kwibanda cyane bishobora kubuza gukura cyangwa no gutera ibimera. Ibimera bya Dicotyledonous byumva Auxin kuruta ibimera bya monocotyledon; ibimera bikomoka ku bimera byumva cyane kuruta imyororokere; imizi yunvikana kurusha amababi, kandi amababi yunvikana kuruta ibiti, nibindi.
