Isixazululo esingu-0.03% S-abscisic acid (S-ABA) silawula kahle ukukhula kwerayisi, sithuthukisa ukukhula kwezimpande, sikhulise isisindo sokwesaba, futhi sikhulise isivuno. Ukwenyuka kwesivuno okuqinisekiswe esidlangalaleni kusuka cishe ku-7.8% kuya ku-11.1%, okunemiphumela ebaluleke nakakhulu ebonwa ngaphansi kwezimo zokucindezeleka kukasawoti.
Izindlela Eziyinhloko Zesenzo
I-S-abscisic acid yaziwa ngokuthi "i-growth-bancing factor" kanye "nesici sokumelana nokucindezeleka" kwerayisi. Imisebenzi yayo eyinhloko ibonakala ngezindlela ezimbili:
Umthetho Wokukhula: Ilinganisa i-hormone metabolism, ikhuthaza ukukhula kwezimpande, ithuthukise ikhono lesithombo lokumunca amanzi nezakhamzimba, futhi ikhuthaze izithombo eziqinile. Iphinde ilinganise ukukhula kwezitshalo nokuzala, ikhuthaze ukuthuthukiswa kwamathila akhiqizayo kuyilapho inciphisa angakhiqizi.
Ukwenza kusebenze Ukumelana Nengcindezi:Kusebenza njengesithunywa esicupha ukuvezwa kwezakhi zofuzo ezimelana nengcindezi, kwenza kusebenze amasosha omzimba asabela ekucindezelekeni kwesitshalo selayisi. Lokhu kuthuthukisa ukubekezelela isomiso, amazinga okushisa aphezulu, amakhaza, usawoti kanye nezifo, ngaleyo ndlela kunciphisa ukuvimbela ukukhula okubangelwa izindawo ezimbi futhi kuqinisekiswe isivuno esizinzile.

Ukuthuthukisa Ukuthuthuka Kwezimpande: Ukucwiliswa kwembewu ngaphambi kokuhlwanyela kukhuthaza ukukhula kwezimpande futhi kuthuthukisa amandla okumunca izakhi. Lokhu kufinyeza isikhathi sokululama ngemva kokufakelwa kabusha, okuvumela izithombo ukuba zingene esigabeni esivamile sokukhula ngokushesha. Ngaphansi kokucindezeleka kukasawoti, igcina amandla ezimpande, iqinisekisa ukutholakala okuqhubekayo kwezakhi.
Ukwandisa Isisindo Sokuthuthumela Nokukhiqiza: Kuthuthukisa izinga lokusetha imbewu, kwandisa isisindo sezinhlamvu ezingu-1,000, kunciphisa ukuwohloka kwe-spikelet, futhi kuthuthukise ukugcwaliswa okusanhlamvu, ekugcineni kuholele ekuvuneni okuphezulu. Idatha yocwaningo lomphakathi ikhombisa ukuthi ngaphansi kwezimo ezijwayelekile zokulima, ukusetshenziswa kwe-S-ABA erayisini eliyingxubevange kungakhuphula isivuno ngo-7.8% -11.1%. Emasimini anosawoti omningi, wehlisa ngokuphawulekayo imiphumela evimbelayo yosawoti enanini lama-panicle akhiqizayo kanye nesilinganiso sokusetha imbewu, ngaleyo ndlela kugcinwe noma kukhuphule isivuno—ngokwanda okudlula u-14% kwezinye izimo. Imiyalo yokusebenzisa i-S-abscisic acid (yokulawula ukukhula kwerayisi)
Lo mkhiqizo usetshenziselwa ngokuyinhloko ukucwilisa imbewu yerayisi ngaphambi kokuhlwanyela. Nciphisa umkhiqizo ku-concentration ye-1:750–1:1000 njengoba kucacisiwe, bese ucwilisa imbewu endaweni yokushisa ye-ambient amahora angu-24-36, uqinisekise ukuthi izinga lamanzi lanele ukuwacwilisa ngokugcwele. Ngemva kokucwiliswa emanzini, hlambulula imbewu ngamanzi ahlanzekile, bese uqhubeka nokuhluma okujwayelekile kanye nezinqubo zokuhlwanyela.
