I-S-Abscisic Acid (S-ABA) iboniswe ukuthi inemiphumela ecacile ekuthuthukiseni ushukela wamagilebhisi, umbala, kanye nokuthuthukiswa kwekhwalithi. Umsebenzi wayo oyinhloko ukukhulisa kakhulu ukuqoqwa kwe-anthocyanin nokukhuthaza umbala. Kodwa-ke, imiphumela yayo ekuthuthukisweni kukashukela kanye nokwehliswa kwe-asidi kube yisihloko semiphumela yocwaningo eyahlukene:
Imiphumela Ebalulekile
Ukuthuthukisa Umbala: I-S-Abscisic Acid inyusa kakhulu ukunqwabelana kwe-anthocyanin. Lokhu okwamanje kuyisivumelwano emphakathini wezemfundo. Ucwaningo oluningi luye lwaqinisekisa ukuthi ukusetshenziswa kwangaphandle kwe-S-Abscisic Acid kungalawula ngokuphawulekayo ukuvezwa kwezakhi zofuzo ezihlobene ne-anthocyanin synthesis (njenge-VvCHS, i-VvUFGT, ne-VvDFR) esikhumbeni samagilebhisi, ekugcineni kwandise inani eliphelele le-anthocyanin esikhumbeni. Lokhu kusebenza ezinhlotsheni eziningi futhi kuphumela ekujuleni kombala wamagilebhisi ojule kakhulu, okuxazulula ngempumelelo inkinga yombala ongemuhle.
I-S-Abscisic Acid Ukuthuthukiswa Koshukela kanye Nokunciphisa I-Acid: Imiphumela ayihambisani. Ucwaningo oluningi luqinisekisa ukuthi i-S-Abscisic Acid yangaphandle iyodwa... Ukwelashwa nge-asidi kungakhuphula okuqukethwe kokunciphisa ushukela kanye nezinto eziqinile ezincibilikayo, kuyilapho kunciphisa okuqukethwe kwe-asidi e-titratable, kuthuthukisa isilinganiso se-sugar-acid, kanye nokuthuthukisa ukunambitheka kwesithelo.
Indlela Yesenzo: I-S-Abscisic acid iyihomoni ewumongo elawula ukuvuthwa kwamagilebhisi kanye nokushintsha kombala. Ikhuthaza ukuqoqwa kukashukela oncibilikayo ngokulawula izinqubo ezihlobene nokuthutha ushukela, kuyilapho ngesikhathi esifanayo ivuselela ukuvezwa kwezakhi zofuzo ezibalulekile endleleni ye-anthocyanin synthesis, ekugcineni ikhuthaza ukuvuthwa nokuthuthukisa ikhwalithi. (Ucwaningo lwezemfundo lwamazwe ngamazwe).
Izinyathelo Zokusebenzisa: Kunconywa ukufafaza izixha zamagilebhisi lapho amagilebhisi esefike ku-20%–30% ekuvuthweni, ngokugxilisa okunconywayo kuka-100-200 mg/L. Ukufafaza ama-bunches kusebenza kakhulu kunokufafaza amaqabunga. Ukusetshenziswa ngokweqile kungase kubangele umbala wesikhumba samagilebhisi obumnyama futhi obuthakathaka, kube nomthelela omubi kwikhwalithi yokubukeka.
