Mafotokozedwe Akatundu
Paclobutrazol ndi chowongolera kukula kwa mbewu za triazole chomwe chinapangidwa m'zaka za m'ma 1980 ndi inhibitor ya endogenous gibberellin synthesis.Itha kuchedwetsa kukula kwa mbewu, kuletsa kutalika kwa tsinde, kufupikitsa ma internodes, kulimbikitsa kulima mbewu, kukulitsa kukana kwa mbewu ndikuwonjezera zokolola.Zinawonjezeranso ntchito ya indoleacetic acid oxidase ndikuchepetsa kuchuluka kwa IAA yokhazikika mu mbande za mpunga.Mwachionekere chimafooketsa mpunga, mmera pamwamba kukula kupambana, amalimbikitsa mbali Bud (Tiller) kukula.Maonekedwe a mbande anali aafupi, amphamvu ndi olima, ndipo masamba anali obiriwira.Mizu yokhazikika bwino.Kafukufuku wa anatomical anasonyeza kuti Paclobutrazol akhoza kupanga maselo a muzu, tsamba m'chimake ndi tsamba la mpunga mbande zing'onozing'ono ndipo selo wosanjikiza aliyense chiwalo kuchuluka.Zotsatira za kufufuza kwa tracer zimasonyeza kuti Paclobutrazol akhoza kutengedwa ndi mbewu za mpunga, masamba ndi mizu.Ambiri a Paclobutrazol omwe amatengedwa ndi masamba amakhalabe m'gawo loyamwa ndipo samatulutsidwa kunja.Kutsika kwa Paclobutrazol kumawonjezera mphamvu ya photosynthetic ya masamba a mbande ya mpunga ndipo kuchuluka kwakukulu kunalepheretsa photosynthetic bwino.Kupumira kwa mizu kunawonjezeka, kupuma kwa nthaka ndi kumtunda kunachepa, kukana kwa Stomata kunawonjezeka, ndipo kutuluka kwa tsamba kunachepa.
Paclobutrazol ndi oyenera mpunga, tirigu, chiponde, mtengo wa zipatso, fodya, kugwiririra, soya, maluwa, udzu ndi mbewu zina.
●Biochemistry:
Imalepheretsa gibberellin ndi sterol biosynthesis motero kuchuluka kwa magawo a cell.
●Kachitidwe:
Zowongolera zakukula kwa zomera zimatengedwa kupita ku xylem kudzera m'masamba, tsinde, kapena mizu, ndikusamutsira ku ma meristem ang'onoang'ono.Zimapanga zomera zophatikizika komanso zimakulitsa maluwa ndi zipatso.
●Zogwiritsa:
Amagwiritsidwa ntchito pamitengo ya zipatso kuti alepheretse kukula kwa vegetative ndi kukonza zipatso;
pa zokongoletsera zobzalidwa mphika ndi mbewu zamaluwa (monga chrysanthemums, begonias, freesias, poinsettias ndi mababu) kuti alepheretse kukula;
pa mpunga kuonjezera ulimi, kuchepetsa malo ogona, ndi kuonjezera zokolola;
pamasamba kuti muchepetse kukula;ndi pa mbewu za udzu kuti muchepetse kutalika ndi kupewa malo okhala.
Itha kugwiritsidwa ntchito ngati tsinde la masamba, ngati dothi lonyowa, kapena jekeseni wa thunthu.Ali ndi ntchito yolimbana ndi mildew ndi dzimbiri.
●Phytotoxicity:
Non-phytotoxic, ngakhale imakulitsa kubiriwira.Mawanga ena adziwika pamasamba a periwinkle pa kutentha kwakukulu.
●Kulongedza mu 25KG / Chikwama
