Prohexadione calcium inzvimbo yakaderera-chepfu, inosarira-isina girinhi yekukura kwemiti inoshandiswa zvakanyanya muzvirimwa zvegramineous (semupunga, gorosi, uye bhari) kusimudzira kuramba kwekugara uye kupa akawanda mabhenefiti anosanganisira kuwedzera goho uye mhando yakavandudzwa.
Prohexadione calcium maitiro ekuita uye maitiro:
1. Inhibition yegibberellin synthesis:Nekudzivisa biosynthesis ye gibberellins (kunyanya GA₁) mumiti, inodzora kukura kwakanyanyisa, inopfupisa internodes, uye inosimbisa matanda, nokudaro kuvandudza zvakanyanya kuramba kwekugara.
2. Kukurudzira kukura kwekubereka: Nekudzivisa kukura kwezvinomera, hazvidziviriri gibberellin synthesis muzviyo nemichero, iyo inobatsira pakuwedzera kwembeu yekuisa chiyero, zviuru-zviyo kurema, uye goho.
3. Kuwedzera kusatya: Kunonatsiridza kusawirirana kwembesa kuzvirwere (semupunga wemupunga neshizha), kusanaya kwemvura, kuderera kwekushisa, uye kukuvara kwesora.
4. Kuchengetedza zvakatipoteredza:Nguva pfupi yehupenyu (<24 maawa muvhu), metabolites yayo carbon dioxide nemvura, uye haina simba pazvirimwa zvinotevera.
