Izidakamizwa zePaclobutrazole (Paclo)
I-Paclobutrazole (i-Paclo) iwubuthi obuphansi futhi ivimbela ukukhula kwezitshalo ngempumelelo kakhulu. Inesikhathi eside sokusebenza kahle kanye nohlobo olubanzi kakhulu lomsebenzi, futhi imunca kalula izimpande, iziqu namaqabunga ezitshalo.
I-Paclobutrazole (Paclo) isetshenziswa ezitshalweni ezihlukahlukene ezifana nerayisi, ukolweni, imifino, nezihlahla zezithelo. I-Paclobutrazole (i-Paclo) ivimbela ukukhula kwezitshalo ezibanzi. Ingavimbela ukuhlanganiswa kwama-gibberellins angapheli ezitshalweni futhi inciphise ukuhlukana nokwelulwa kwamaseli ezitshalo. Ngemva kokumuncwa izimpande, iziqu, namaqabunga, iyancipha, ithuthukise amagatsha, futhi izimpande ukuze kwandiswe okuqukethwe kwe-chlorophyll. Kungabambezela ukuguga kwamaqabunga futhi kuthuthukise ukumelana nokucindezeleka. Isetshenziswa kakhulu elayisi, ukudlwengula, ubhontshisi wesoya nezinye izitshalo ze-cereal ngokufafaza noma ukucwilisa imbewu.
Imiphumela enamandla yePaclobutrazole (Paclo)
I-Paclobutrazole (i-Paclo) iyisilawuli sokukhula kwezitshalo. Ngokuyinhloko ivimbela i-biosynthesis ye-gibberellins ezitshalweni, ibambezela ukukhula kwezitshalo, ilawula ukunwebeka kweziqu zezitshalo, ifinyeze i-internode yezitshalo, ikhuthaze ukulima kwezitshalo, futhi ingakhuthaza ukuhlukaniswa kwezimbali zezitshalo, ukwandisa ukumelana nokucindezeleka kwezitshalo, ukwandisa isivuno kanye neminye imiphumela.
I-1.I-Paclobutrazole (i-Paclo) ishintsha izinga lamahomoni angapheli
I-Paclobutrazole (i-Paclo) ingavimbela ukuhlanganiswa kwe-gibberellin, ibambezele ukukhula, ifinyeze i-internode, nezitshalo ezincane. Yehlisa ukwakheka noma i-metabolism ye-indole acetic acid, ikhuphule okuqukethwe kwe-abscisic engapheli yezitshalo, futhi ingalawula nokukhishwa kwe-ethylene kwezitshalo.
I-Paclobutrazole (i-Paclo) ingenza amaqabunga esitshalo abe luhlaza mnyama, akhulise okuqukethwe kwe-photosynthetic pigments njenge-chlorophyll, futhi andise i-nucleic acid kanye ne-protein content esitshalweni. Ingathuthukisa ikhono lokulwa nokuguga lezitshalo futhi yenze izitshalo zibe nobungqabavu obuqinile.
I-2.I-Paclobutrazole (i-Paclo) ithuthukisa ukumelana nokucindezeleka kwezitshalo
I-Paclobutrazole (i-Paclo) ingathuthukisa ikhono lezitshalo lokumelana nokucindezeleka kanye namagciwane e-pathogenic. Kungabangela amangqamuzana e-epidermal esitshalo ukuthi avuvuke, kubangele ukuthi i-stomata icindezele futhi icwiliswe, ibangele ukwanda kwe-stomatal ukumelana, inciphise ukuphefumula, futhi inciphise ukulahlekelwa kwamanzi. Ngokunciphisa ukulahlekelwa kwamanzi, ukucindezeleka kwamangqamuzana ezitshalo kuyehla, ukukhula okuvamile nokuthuthuka kungaqhubeka, futhi ikhono lesitshalo lokumelana nesomiso liyakhula.
Ukusetshenziswa kwe-Paclobutrazole (Paclo) kungathuthukisa ukumelana kwesitshalo ekulimaleni okubandayo kanye nokubanda. Ukusetshenziswa kwe-paclobutrazole kwandisa okuqukethwe kwe-hormone yokucindezeleka i-abscisic acid esitshalweni futhi kunciphisa umonakalo kulwelwesi lwamangqamuzana eqabunga olubangelwa ukushisa okuphansi.
I-3.I-Paclobutrazole (i-Paclo) ikhuthaza ukuhluma kwehlumela le-lateral nokukhula
I-Paclobutrazole (i-Paclo) ingavimbela ukubusa kwe-apical futhi ikhuthaze ukuhluma nokukhula kwama-lateral buds. Isibonelo, ukusetshenziswa kwe-Paclobutrazole (i-Paclo) kungabangela izithombo zelayisi ukuthi zilime kusenesikhathi noma zilinywe kaningi, izitshalo ziba mfishane, futhi isisekelo sesiqu siba sishubile.
I-4.I-Paclobutrazole (i-Paclo) inomphumela we-bactericidal
I-Paclobutrazole (i-Paclo) yaqala ukwenziwa njenge-fungicide. Inomsebenzi ovimbela ukulwa namagciwane angaphezu kwe-10 e-pathogenic afana ne-rape sclerotinia, i-wheat powdery mildew, i-rice sheath blight kanye ne-apula anthracnose. Ine-spectrum ebanzi ye-antibacterial properties futhi ingalawula notshani. Zilimaze, zenze ukhula lube luncane, lubambezele ukukhula kwalo, futhi lunciphise umonakalo.
5. Ukusetshenziswa kwePaclobutrazole (Paclo) ezihlahleni zezithelo
Lawula ukukhula kwegatsha kanye nezihlahla zezithelo ezincane; thuthukisa ukuhlukaniswa kwezimbali futhi ukwandise ivolumu yezimbali; lungisa izinga lokumisa izithelo; shintsha isikhathi sokuvuna ukuze uthuthukise izinga lezithelo; ukunciphisa ukuthenwa kwehlobo; kanye nokwenza ngcono isomiso kanye nokumelana namakhaza kwezihlahla zezithelo.
I-Paclobutrazole (Paclo) isetshenziswa ezitshalweni ezihlukahlukene ezifana nerayisi, ukolweni, imifino, nezihlahla zezithelo. I-Paclobutrazole (i-Paclo) ivimbela ukukhula kwezitshalo ezibanzi. Ingavimbela ukuhlanganiswa kwama-gibberellins angapheli ezitshalweni futhi inciphise ukuhlukana nokwelulwa kwamaseli ezitshalo. Ngemva kokumuncwa izimpande, iziqu, namaqabunga, iyancipha, ithuthukise amagatsha, futhi izimpande ukuze kwandiswe okuqukethwe kwe-chlorophyll. Kungabambezela ukuguga kwamaqabunga futhi kuthuthukise ukumelana nokucindezeleka. Isetshenziswa kakhulu elayisi, ukudlwengula, ubhontshisi wesoya nezinye izitshalo ze-cereal ngokufafaza noma ukucwilisa imbewu.
