Zowongolera kukula kwa zomera zimaphatikizapo mitundu yambiri, iliyonse ili ndi ntchito yakeyake komanso kuchuluka kwa ntchito. Zotsatirazi ndi zina zowongolera kukula kwa Zomera ndi mawonekedwe ake omwe amawonedwa kuti ndi osavuta kugwiritsa ntchito komanso ogwira mtima:

Zowongolera kukula kwa zomera (PGRs) ndi mankhwala opangidwa mwaluso omwe ali ndi zotsatira zofanana za thupi komanso mawonekedwe ofanana ndi mahomoni omera. Zowongolera kukula kwa mbewu ndi m'gulu lalikulu la mankhwala ophera tizilombo ndipo ndi gulu la mankhwala ophera tizilombo omwe amawongolera kukula ndi kukula kwa mbewu, kuphatikiza mankhwala opangidwa ofanana ndi mahomoni achilengedwe achilengedwe ndi mahomoni otengedwa kuchokera ku zamoyo.

Auxin ndi indole-3-acetic acid, yokhala ndi formula ya maselo C10H9NO2. Ndilo timadzi tambiri tomwe tinapezeka tolimbikitsa kukula kwa mbewu. Mawu achingerezi amachokera ku mawu achi Greek auxein (kukula). Chopangidwa choyera cha indole-3-acetic acid ndi kristalo woyera ndipo sichisungunuka m'madzi. Amasungunuka mosavuta mu zosungunulira organic monga ethanol ndi ether. Imakhala ndi okosijeni mosavuta ndipo imasandulika kukhala ofiira owala, ndipo ntchito yake yokhudzana ndi thupi imachepetsedwa. Indole-3-acetic acid muzomera ikhoza kukhala yomasuka kapena yomangidwa (yomangidwa).

Kusiyana kwa ntchito: 24-epibrassinolide ndi 97% yogwira, pomwe 28-homobrassinolide ndi 87% yogwira. Izi zikuwonetsa kuti 24-epibrassinolide ili ndi ntchito yayikulu pakati pa ma brassinolides opangidwa ndi mankhwala.
