Waxaa hadda jira shan qaybood oo la aqoonsan yahay oo ah phytohormones, kuwaas oo kala ah auxin, Gibberellic Acid GA3, Cytokinin, ethylene, iyo asiidh abscisic ah. Dhawaan, brassinosteroids (BRs) ayaa si tartiib tartiib ah loo aqoonsaday inay yihiin qaybta lixaad ee ugu weyn ee phytohormones.

Brassinolides waxaa lagu heli karaa shan qaybood oo kala duwan:

(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 dabiiciga ah

1. Badeecadani waa warshad soo saarta auxin-inducing factor, taas oo ka kooban 5 nooc oo ah auxins dhirta endogenous oo ay ku jiraan indoles iyo 2 nooc oo fitamiino ah. Formulated with exogenous dheeri ah, waxay kordhin kartaa waxqabadka auxin synthase endogenous ee dhirta waqti gaaban iyo in ay keento synthesis of auxin endogenous iyo muujinta hidda, si aan toos ahayn kor u qaybinta unugyada, elongation iyo ballaarinta, induces formation of rhizomes, iyo faa'iido leh koritaanka xidid cusub iyo nidaamka vascularization kala duwanaansho, kor u formation of xididdada adventitious ee gooyn.

INDOLE-3-BUTYRIC AACID BATAASIYAM CUSBADA (IBA-K) waa nidaamiye korriinka dhirta oo kor u qaada xididada dalagga. Inta badan waxaa loo isticmaalaa si kor loogu qaado koritaanka xididada xididada dalagga. Marka lagu daro Naphthalene acetic acid (NAA), waxaa laga samayn karaa alaab xidid. INDOLE-3-BUTYRIC AACID BOTASSIUM SALT (IBA-K) waxaa loo isticmaali karaa jarista xididada geedo, iyo sidoo kale in lagu daro bacriminta dareeraha, bacriminta waraabka faleebo iyo alaabooyin kale si kor loogu qaado xididada dalagga iyo hagaajinta heerka badbaadada gooyn.
