Isilawuli sokukhula kwezitshalo:S-abscisic acid
I-S-abscisic acid inemiphumela yempilo enjengokubangela ukuvuthwa kwehlumela, ukuchitheka kwamaqabunga kanye nokuvimbela ukukhula kwamaseli, futhi yaziwa nangokuthi "ihomoni elele".
Yatholwa cishe ngo-1960 futhi yaqanjwa ngephutha ngoba yayihlobene nokuwa kwamaqabunga ezitshalo. Kodwa-ke, manje sekuyaziwa ukuthi ukuwa kwamaqabunga ezitshalo nezithelo kubangelwa i-ethylene.
I-S-abscisic acid ingumkhiqizo oluhlaza ovumela imvelo,I-S-abscisic acid iyisithako esisebenzayo sokukhula kwesitshalo.
Le nto yemvelo ivame ukutholakala ezitshalweni. Ngokwemvelo kuqukethwe izithelo, imifino kanye nokusanhlamvu okudliwa abantu futhi kuphephile kubantu kanye nemvelo.
Izinto zokusetshenziswa ezisetshenziswa enqubweni yokukhiqiza ye-abscisic acid technical yonke ayiyona into enobuthi futhi ayinabungozi kwezolimo kanye nemikhiqizo eseceleni. Itholakala ngokuvutshelwa kwe-microbial, ngaphandle kokwengezwa kwezinto eziyingozi noma izinto, futhi azikho izakhi ezinobuthi ekwakhekeni kwayo kwamakhemikhali.
Ukusetshenziswa kwe-S-abscisic acid
I-1.S-abscisic acid iyisivimbeli esisebenzayo sokuhluma kwembewu
I-S-abscisic acid ingasetshenziselwa ukugcina imbewu kanye nokulondoloza ukuhluma.
2. I-S-abscisic acid ingakhuthaza ukuqoqwa kwezinto zokugcina imbewu nezithelo, ikakhulukazi ukuqoqwa kwamaprotheni okugcina kanye noshukela.
Ukusebenzisa i-abscisic acid ezigabeni zokuqala zokukhula kwembewu nezithelo kungafeza inhloso yokwandisa isivuno sezitshalo zokusanhlamvu nezihlahla zezithelo.
3. I-S-abscisic acid ingathuthukisa ukumelana nokubanda nesithwathwa kwezitshalo.
I-S-abscisic acid ingasetshenziswa ukusiza izitshalo ukumelana nezinga lokushisa eliphansi kanye nokulimala okubanda ekuqaleni kwentwasahlobo futhi kutshalwe izinhlobo zezitshalo ezintsha ezimelana namakhaza aqinile.
4. I-S-abscisic acid ingathuthukisa ukumelana nesomiso kanye nokubekezelela usawoti-alkali wezitshalo.
I-S-abscisic acid inenani eliphakeme kakhulu lokusetshenziswa ekusizeni abantu ukuthi bamelane nezimo zesomiso, ukuthuthukisa nokusebenzisa amasimu anesivuno esimaphakathi nesiphansi, kanye nokugawulwa kwamahlathi.
5. I-S-abscisic acid iyisivimbeli esiqinile sokukhula.
I-S-abscisic acid ingavimbela ukukhula kwezitshalo zonke noma izitho ezizimele. Umphumela we-ABA ekukhuleni kwezitshalo uphambene nalowo we-IAA, GA, ne-CTK, futhi uvimbela ukuhlukana kwamaseli nokwelulwa. Vimbela ukukhula nokukhula kwezitho ezinjengama-bud sheaths, amahlumela, izimpande, nama-hypocotyl.
6. Ukusetshenziswa kwe-S-abscisic acid ezimbalini zasengadini
Njengoba i-S-abscisic acid (ABA) ingavala ngokushesha izimbotshana eziyinhloko zamaqabunga, ingasetshenziswa ukulondoloza izimbali, ukwandisa isikhathi sokuqhakaza (isimiso sezinto ezigcina izimbali), ukulawula isikhathi sokuqhakaza, nokukhuthaza ukumila kwezimpande (umthethonqubo we-horticultural).
Ungayisebenzisa kanjani i-S-abscisic acid ngokuhlangana
1. I-S-abscisic acid + auxin
Ukukhuthaza ikakhulukazi ukumila kwezimpande kanye nokuncipha kwezithombo ngemuva kokutshala izithombo, noma ukusika izithombo, njll.
2. I-Ethylhexyl + S-abscisic acid, S-abscisic acid + gibberellin
Umsebenzi uwukulawula ukukhula okunamandla nokwandisa izinga lokumiswa kwezithelo.
3. I-Anti-agonist + i-S-abscisic acid
Khulisa ukumuncwa kwezakhamzimba, ukhuthaze ukukhula kwezithombo, wandise inani eliphelele lento eyomile, futhi uthuthukise ukumelana nokubanda, ukumelana nesomiso, ukumelana nezifo, nokumelana nezinambuzane.
