Yiziphi izilawuli zokukhula kwezitshalo ezikhuthaza ukuvuthwa kokuqala kwezitshalo?
.
Izilawuli zokukhula kwezitshalo ezikhuthaza ukuvuthwa kusenesikhathi kwezitshalo ikakhulukazi zihlanganisa lezi zinhlobo ezilandelayo:
I-Gibberellic Acid (GA3):
I-Gibberellic Acid iyisilawuli sokukhula kwezitshalo esine-spectrum esibanzi esingakhuthaza ukukhula nokuthuthukiswa kwezitshalo, sizenze zisheshe zivuthwe, zandise isivuno, futhi zithuthukise ikhwalithi. Ilungele izitshalo ezinjengokotini, utamatisi, izihlahla zezithelo, amazambane, ukolweni, ubhontshisi wesoya, ugwayi nelayisi.
I-Forchlorfenuron (CPPU/ KT-30):
I-Forchlorfenuron inomsebenzi we-cytokinin, ongakhuthaza ukuhlukaniswa kwamaseli, ukuhlukaniswa, ukwakheka kwezitho, nokuthuthukisa i-photosynthesis, ngaleyo ndlela kukhuthaze ukukhula kweziqu, amaqabunga, izimpande, nezithelo. Ekutshaleni ugwayi, kungakhuthaza i-hypertrophy yamaqabunga futhi kwandise isivuno; ezitshalweni ezifana nama-eggplant, ama-apula, notamatisi, kungakhuthaza ukuthela futhi kwandise isivuno.
I-Sodium Nitrophenolates (Atonik):
I-Atonik iyisilawuli sokukhula kwezitshalo esine-spectrum esibanzi esingakhuthaza ukugeleza kwe-cell protoplasm, sithuthukise ubungqabavu bengqamuzana, sisheshise ukukhula nokuthuthuka kwezitshalo, sikhuthaze ukuqhakaza kwezimbali kanye nezithelo, sikhulise isivuno, futhi sithuthukise ukumelana nokucindezeleka. Ilungele izitshalo ezihlukahlukene, njengama roses nezimbali.
I-1-Naphthyl Acetic Acid (NAA):
I-NAA iyisilawuli sokukhula kwezitshalo esine-spectrum esibanzi, esinobuthi obuphansi esingakhuthaza ukwakheka kwezimpande nezimpande ezizayo, sivimbele ukwehla kwezithelo, futhi sikhulise izinga lokumiswa kwezithelo. Emazingeni aphezulu, ingavuthwa; ekugxilweni okuphansi, kungakhuthaza ukwanda kwamaseli nokuhlukana.
I-Ethephon:
I-Ethephon iyisilawuli sokukhula kwezitshalo esine-organophosphorus esetshenziswa kakhulu ukukhuthaza ukuvuthwa kwezithelo nokubala imibala, ukukhuthaza ukuchitheka kwamaqabunga nezithelo, futhi kwandise ingxenye yezimbali zabesifazane noma izitho zabesifazane. Ivame ukusetshenziselwa ukuvuthwa izithelo.
Lezi zilawuli zikhuthaza ukukhula nokuthuthukiswa kwezitshalo ngokusebenzisa izindlela ezahlukene, ngaleyo ndlela kufinyelele umphumela wokuvuthwa kwangaphambi kwesikhathi. Lapho usebenzisa, kuyadingeka ukukhetha isilawuli esifanele kanye nokugxilisa ingqondo ngokuya ngesitshalo esithile kanye nesigaba sokukhula ukuze uqinisekise umphumela omuhle kakhulu.
