Gibberellic Acid GA3 waa nidaamiye korriin dhireed ballaaran oo si weyn loogu isticmaalo geedaha miraha. Waxay leedahay saamaynta dardargelinta koritaanka iyo horumarinta dhirta iyo kor u qaadida ballaarinta unugyada. Waxaa badanaa loo isticmaalaa in lagu kiciyo parthenocarpy, ilaalinta ubaxa iyo miraha.

Hormoonka koritaanka dhirta waa nooc ka mid ah sunta cayayaanka loo isticmaalo si loo xakameeyo koritaanka iyo korriinka dhirta. Waa xarun synthetic ah oo leh saameyn hormoonnada dhirta dabiiciga ah. Waa taxane gaar ah oo sunta cayayaanka ah. Waxay nidaamin kartaa koritaanka iyo horumarinta dhirta marka qadarka codsigu ku habboon yahay

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
