Prohexadione calcium ndi kawopsedwe kakang'ono, wopanda zotsalira za zomera zobiriwira zomwe zimagwiritsidwa ntchito kwambiri muzomera za gramineous (monga mpunga, tirigu, ndi balere) kukulitsa kukana kwa malo okhala ndikupereka maubwino angapo kuphatikiza zokolola zambiri komanso kuwongolera bwino.
Prohexadione calcium imagwirira ntchito ndi mawonekedwe:
1. Kuletsa kwa gibberellin kaphatikizidwe: Mwa kuletsa biosynthesis ya gibberellins (makamaka GA₁) muzomera, imayendetsa kukula kwa tsinde, kufupikitsa internodes, ndi kulimbikitsa zimayambira, motero kumapangitsa kwambiri kukana kwa malo ogona.
2. Kulimbikitsa kukula kwa uchembere: Ngakhale kulepheretsa kukula kwa zomera, sikulepheretsa kaphatikizidwe ka gibberellin mumbewu ndi zipatso, zomwe zimapindulitsa pakukula kwa mbeu, kulemera kwa chikwi, ndi zokolola.
3. Kumathandiza kupirira kupsinjika: Kumathandiza kuti mbeu zisagonje ku matenda (monga mpunga wabodza ndi mawanga a masamba), chilala, kutentha pang'ono, ndi kuwonongeka kwa udzu.
4. Kusamalira chilengedwe: Theka la moyo waufupi (<24 maola m'nthaka), metabolites ake ndi carbon dioxide ndi madzi, ndipo alibe mphamvu pa mbewu zotsatira.
