Tengani ma brassinolides angapo monga zitsanzo:
24-epibrassinolide:
Kuyang'ana pa kulimbikitsa kukula kwa mizu ndi kukulitsa kukana kwa mbewu, makamaka pansi pamikhalidwe yovuta monga chilala ndi mchere, zimatha kupititsa patsogolo kupulumuka ndi zokolola za mbewu. Ikhoza kulimbikitsa magawano ndi kutalika kwa maselo a mizu, kuonjezera malo a mizu, ndi kupititsa patsogolo kuyamwa kwa madzi ndi zakudya. Kwa mbewu zomwe zili mu siteji ya mbande, kugwiritsa ntchito 24-epibrassinolide kumatha kulimbikitsa kukula kwa mizu mwachangu ndikuyala maziko olimba akukula mtsogolo.

28-homobrassinolide:
Zimagwira makamaka pakukula kwa tsinde ndi masamba, zimalimbikitsa kugawanika kwa maselo ndi kutalika, kumapangitsa kuti zomera zikhale zamphamvu, masamba ochuluka komanso okulirapo, potero kumapangitsa kuti photosynthetic iwonongeke. Ikhoza kulimbikitsanso kukula kwa zipatso, kuonjezera zokolola ndi khalidwe. Amagwiritsidwa ntchito kwambiri muzomera monga masamba ndi zipatso, ndipo amatha kuwonjezera zokolola komanso mtengo wamtengo wapatali.

28-epihomobrassinolide:
Zili ndi zotsatira ziwiri zolimbikitsa kukula komanso kukulitsa kukana kupsinjika. Izo osati kulimbikitsa tsinde ndi masamba kukula, komanso kusintha kukana kwa mbewu kuti chokhwima mapangidwe. Ngakhale kupititsa patsogolo zokolola ndi ubwino wa mbewu, kungathenso kupititsa patsogolo mphamvu ya mbewu kulimbana ndi matenda ndi tizilombo towononga tizilombo, kuchepetsa kugwiritsa ntchito mankhwala ophera tizilombo, ndikutsatira ndondomeko ya ulimi wobiriwira.

Kugwiritsa ntchito sayansi kungapindule kwambiri
Njira zogwiritsira ntchito Brassinolide makamaka ndi kupopera mbewu mankhwalawa ndi kuthirira mizu. Kupopera mbewu kwa foliar kumayamwa mwachangu ndipo kumagwira ntchito mwachangu, komwe kuli koyenera pamikhalidwe yomwe kufunikira kowonjezera zakudya mwachangu kapena kuthana ndi zovuta zadzidzidzi. Kuthirira kwa mizu ya dothi kumayamwa pang'onopang'ono ndipo kumakhala ndi zotsatira zokhalitsa, zomwe ndizoyenera kulimbikitsa kukula kwa mizu ndi kupititsa patsogolo kupirira kupsinjika kwa mbewu.

Kusankha njira yogwiritsira ntchito kumadalira mtundu wa mbewu, siteji ya kukula ndi zosowa zenizeni. Mwachitsanzo, pa mbeu zomwe zatsala pang'ono kubzala, kuthirira kwa mizu ya nthaka kungagwiritsidwe ntchito kulimbikitsa kukula kwa mizu; pa nthawi ya kukula kwa mbeu, kupopera mbewu mankhwalawa kwa masamba kungagwiritsidwe ntchito kulimbikitsa kukula kwa tsinde ndi masamba ndi kukulitsa zipatso; kwa mbewu zomwe zikudwala tizirombo ndi matenda kapena zovuta, kupopera mbewu mankhwalawa kungagwiritsidwe ntchito powonjezera zakudya mwachangu ndikuchepetsa kupsinjika.
