Prohexadione calcium (ProCa), raws li kev tswj kev loj hlob ntawm cov nroj tsuag, muaj ntau yam cuam tshuam rau cov ntoo txiv hmab txiv ntoo, suav nrog kev tswj tua, kev txhawb paj, thiab kev txuag txiv hmab txiv ntoo, tshwj xeeb hauv qab no:
Tua tswj tsis cuam tshuam rau kev loj hlob txiv hmab txiv ntoo: Prohexadione calcium inhibits qhov tseem ceeb enzyme (GA20 oxidase) nyob rau hauv gibberellin synthesis, shortening internode ntev, txo cov nroj tsuag qhov siab, thiab tiv thaiv ntau lub caij nplooj zeeg tua loj hlob nyob rau hauv txiv hmab txiv ntoo, thaum tsis cuam tshuam lub endogenous hormone tshuav nyiaj li cas yuav tsum tau rau paj thiab txiv hmab txiv ntoo txoj kev loj hlob, yog li ua tiav tua tswj tsis cuam tshuam rau kev loj hlob ntawm txiv hmab txiv ntoo.
Txhawb kev loj hlob hauv paus: Prohexadione calcium nkoos cag tip cell division, txhawb kev sib sib zog nqus rooting ntawm lub hauv paus ntsiab lus thiab multiplication ntawm lateral roots, txhim kho qia lub zog, thiab txhim kho cov txiv hmab txiv ntoo txoj kev tiv thaiv rau chaw nyob.
Kev ntxhov siab thiab kev txhim kho zoo: Nws ua rau muaj kev sib txuas ntawm cov tshuaj osmoregulatory xws li proline, txhim kho cov txiv hmab txiv ntoo lub peev xwm los tiv thaiv drought thiab kub qis, thaum tseem txhim kho cov txiv hmab txiv ntoo zoo, xws li nce cov kua qab zib cov ntsiab lus los ntawm 2-3 feem pua cov ntsiab lus thiab txo cov citrus tev tsis zoo los ntawm 40%.
Kev nyab xeeb thiab qis qis: Tus nqi degradation nce mus txog 90% hauv 7 hnub tom qab thov, thiab cov seem seem qis dua 0.01 ppm (EU tus qauv), ua rau nws haum rau tag nrho lub caij cog qoob loo.
Kev txuag hluav taws xob thiab ua haujlwm tau zoo: Nws hloov cov tsoos topping thiab pruning ua haujlwm, txo cov nqi zog thiab txhim kho qhov kev tawm tswv yim-tso tawm.
Inducing pathogen resistance: Los ntawm inducing tsim ntawm 3-deoxyflavonoids, nws ua rau cov kab mob tiv thaiv, txo qhov tshwm sim ntawm cov kab mob xws li hluav taws kub blight thiab scab.
