Mmekọrịta dị n'etiti ndị na-ahụ maka uto ihe ọkụkụ
1. Auxins na Gibberellins
Auxins na gibberellins na-egosipụta mmetụta mmekọrịta n'ịkwalite uto. Ịfesa osisi dị iche iche na ngwakọta nke gibberellins na auxins na ntinye kwesịrị ekwesị na-akwalite elongation stem; mmetụta nke ịgbasa auxins naanị adịghị akpọpụta karịa nke gibberellins. Ngwakọta nke abụọ ahụ na-arụpụta nsonaazụ kacha mma.
Auxins na gibberellins na-egosipụta mmekọrịta na-emegiderịta onwe ya gbasara ọdịiche mmekọahụ na kukumba. Mmegide a na-apụta ìhè n'ụzọ bụ isi na njikwa mmekọahụ nke ifuru: auxins na-akwalite ọdịiche nke ifuru nwanyị, ebe gibberellins na-akwalite ọdịiche nke ifuru nwoke. Dịka ọmụmaatụ, ọ bụrụ na a na-eji gibberellins agwọ osisi kukumba a na-agwọ ya na auxins, enwere ike ịkwụsị mmetụta nke auxins, na ntụgharị.
2. Auxins na cytokinins
Mmetụta mmekọrịta dị n'etiti auxins na cytokinin na-egosipụta na ogologo oge nke ọrụ cytokinin mgbe homonụ abụọ dị n'otu oge. Cytokinins nwere ike ịkwalite mbufe polar nke auxins, si otú a na-abawanye ọrụ auxin.
A na-ahụ mmegide dị n'etiti auxins na cytokinins na mmepe nke mpụta buds na osisi dicotyledonous: cytokinins na-akwalite mmepe mpụta, ebe auxins na-egbochi ya. N'ihe gbasara njikwa nke ịchịisi apical, oke cytokinin-to-auxin ruru na-akwado mmepe mpụta mpụta, ebe oke dị ala na-ejigide ikike apical. Otú ọ dị, ihe ndị dị ka kinetin, zeatin, na 6-BA nwere ike igbochi mmetụta na-akwalite uto nke auxins.
3. Auxin na ethylene
Auxins na-akwalite njikọ nke ethylene site n'ịkwalite ọrụ nke ethylene synthase; N'ihi ya, nnukwu mkpokọta auxins na-egbochi uto. Ethylene na-emetụta auxins site na igbochi njem polar ha na biosynthesis, yana site n'ịkwalite ọrụ nke auxin oxidase.
Auxins dị ukwuu na-ebute mmepụta ethylene; ozugbo ethylene kpalitere rute n'ókè ụfọdụ, ọ na-egbochi ọrụ auxin. Nke a na-egosipụta mmekọrịta nzaghachi n'etiti ha abụọ, ọ bụkwa kpọmkwem usoro "nzaghachi" a na-achịkwa uto osisi kwesịrị ekwesị. 4. Gibberellins na Abscisic Acid
Gibberellins na abscisic acid na-egosipụta mmekọrịta na-emegide: gibberellins nwere ike imebi nwa osisi ma ọ bụ dormancy mkpụrụ, ebe abscisic acid na-akwalite dormancy. Ha na-ekekọrịta otu ihe mmalite biosynthetic mana a na-emepụta ya n'okpuru ọnọdụ dị iche iche.
Auxins na gibberellins na-egosipụta mmetụta mmekọrịta n'ịkwalite uto. Ịfesa osisi dị iche iche na ngwakọta nke gibberellins na auxins na ntinye kwesịrị ekwesị na-akwalite elongation stem; mmetụta nke ịgbasa auxins naanị adịghị akpọpụta karịa nke gibberellins. Ngwakọta nke abụọ ahụ na-arụpụta nsonaazụ kacha mma.

2. Auxins na cytokinins
Mmetụta mmekọrịta dị n'etiti auxins na cytokinin na-egosipụta na ogologo oge nke ọrụ cytokinin mgbe homonụ abụọ dị n'otu oge. Cytokinins nwere ike ịkwalite mbufe polar nke auxins, si otú a na-abawanye ọrụ auxin.
