Kuri ubu hari ibyiciro bitanu bizwi bya phytohormone, aribyo auxin, Acide Gibberellic Acide GA3, Cytokinin, Ethylene, na acide abcisic. Vuba aha, brassinosteroide (BRs) yamenyekanye buhoro buhoro nkicyiciro cya gatandatu cyingenzi cya phytohormone.

Brassinolide iraboneka mubyiciro bitanu byibicuruzwa:

(1) 24-trisepibrassinolide: 72962-43-9 C28H48O6

(2) 22,23,24-trisepibrassinolide: 78821-42-9

( 3) 28-epihomobrassinolide: 80843-89-2 C29H50O6

(4) 28-homobrassinolide: 82373-95-3 C29H50O6

(5) Brassinolide Kamere

1.Ibicuruzwa nibihingwa bitera endogenous auxin-itera ibintu, bigizwe nubwoko 5 bwibimera endogenous auxins harimo indoles nubwoko 2 bwa vitamine. Byakozwe hiyongereyeho exogenous, birashobora kongera ibikorwa bya synthase ya endogenous auxin mu bimera mugihe gito kandi bigatera synthesis ya endogenous auxin na gene imvugo, iteza imbere mu buryo butaziguye amacakubiri, kurambura no kwaguka, itera imvubu, kandi ifitiye akamaro imvubu. imizi mishya ikura hamwe na sisitemu yo gutandukanya sisitemu, iteza imbere gushinga imizi ya adventitive yo gutema.

INDOLE-3-BUTYRIC ACID POTASSIUM SALT (IBA-K) nigenzura ryimikurire yibihingwa biteza imbere imizi. Ikoreshwa cyane mugutezimbere imikurire yimizi ya capillary. Iyo uhujwe na acide acide ya Nafthalene (NAA), irashobora gukorwa mubicuruzwa bishinze imizi. INDOLE-3-BUTYRIC ACID POTASSIUM SALT (IBA-K) irashobora gukoreshwa mugukata imizi yingemwe, ndetse no kongeramo ifumbire mvaruganda, ifumbire mvaruganda itonyanga nibindi bicuruzwa kugirango biteze imbere imizi yibihingwa kandi bitezimbere ubuzima bwo gutema ibiti.
