I-Prohexadione calcium iyisilawuli esinobuthi obuphansi, esingenazinsalela sokukhula kwezitshalo esiluhlaza esisetshenziswa kakhulu ezitshalweni zegramineous (njengerayisi, ukolweni, nebhali) ukuze kuthuthukiswe ukumelana nendawo yokulala futhi kunikeze izinzuzo eziningi ezihlanganisa isivuno esikhulayo kanye nekhwalithi ethuthukisiwe.
Indlela yokusebenza ye-Prohexadione calcium nezici:
1. Ukuvinjelwa kwe-gibberellin synthesis:Ngokuvimbela i-biosynthesis ye-gibberellins (ikakhulukazi i-GA₁) ezitshalweni, ilawula ukukhula kwe-stem ngokweqile, ifinyeze ama-internode, futhi iqinise iziqu, ngaleyo ndlela ithuthukise kakhulu ukumelana nendawo yokulala.
2. Ukukhuthazwa kokukhula kokuzala: Nakuba kuvimbela ukukhula kwezitshalo, akuvimbeli ukuhlanganiswa kwe-gibberellin ezinhlamvu nezithelo, okunenzuzo ekukhuliseni izinga lokumisa imbewu, isisindo sezinhlamvu eziyinkulungwane, kanye nesivuno.
3. Ukumelana nokucindezeleka okuthuthukisiwe: Kwenza ngcono ukungezwani kwezitshalo ezifweni (njenge-rice smut namachashaza amaqabunga), isomiso, amazinga okushisa aphansi, nokulimala kwe-herbicide.
4. Inobungani nemvelo:Isikhathi esifushane sokuphila (
