Prohexadione-Ca yog ib tug tshiab cog kev loj hlob regulator muaj peev xwm ntawm precisely tswj cov nroj tsuag qhov siab thiab branching morphology nyob rau hauv horticultural qoob loo. Nws cov txheej txheem ntawm kev nqis tes ua thiab kev siv cov teebmeem tau raug lees paub hauv ntau qhov kev tshawb fawb pom zoo.
Mechanism ntawm Action
Selective Inhibition of Gibberellin (GA₁) Synthesis: Prohexadione calcium feem ntau inhibits biosynthesis ntawm gibberellin (GA₁), uas cuam tshuam nrog qia thiab nplooj elongation, tsis cuam tshuam rau GA₄, uas txhawb paj thiab txiv hmab txiv ntoo txoj kev loj hlob, yog li ua tiav "tswj cov txiv hmab txiv ntoo ntau dhau lawm."
Regulating Endogenous Hormone Balance: Los ntawm kev nce qib ntawm cov tshuaj tiv thaiv kev ntxhov siab xws li cytokinins thiab abscisic acid (ABA), nws txhawb nqa lub paj tawg paj, kev loj hlob hauv paus, thiab txhim kho photosynthetic efficiency.
Tsis muaj residue, Environmentally Friendly: Ib nrab-lub neej luv luv (<24 teev hauv av), degrades rau CO₂, dej, thiab calcium ntsev, ua rau nws muaj kev nyab xeeb rau kev cog qoob loo.
