S-Abscisic Acid (S-ABA) tau pom tias muaj cov txiaj ntsig zoo ntawm cov txiv hmab txiv ntoo qab zib, xim, thiab kev txhim kho zoo. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawm rau txhawm rau anthocyanin thiab txhawb cov xim. Txawm li cas los xij, nws cov txiaj ntsig ntawm kev txhim kho cov suab thaj thiab txo cov kua qaub yog cov ntsiab lus ntawm kev tshawb fawb sib txawv:
Cov teebmeem tseem ceeb
Xim Enhancement: S-Abscisic Acid ua rau kom cov tshuaj anthocyanin ntau ntxiv. Tam sim no qhov no yog kev pom zoo hauv zej zog kev kawm. Ntau qhov kev tshawb fawb tau lees paub tias kev siv exogenous ntawm S-Abscisic Acid tuaj yeem txhim kho qhov kev qhia ntawm anthocyanin synthesis ntsig txog cov noob (xws li VvCHS, VvUFGT, thiab VvDFR) hauv daim tawv nqaij, thaum kawg ua rau tag nrho cov ntsiab lus anthocyanin hauv daim tawv nqaij. Qhov no muaj feem xyuam rau ntau yam thiab ua rau cov xim sib sib zog nqus thiab ntau yam xim txiv hmab txiv ntoo, zoo daws qhov teeb meem ntawm cov xim tsis zoo.
S-Abscisic Acid Sugar Enhancement and Acid Reduction: Cov teebmeem tsis sib xws. Feem ntau cov kev tshawb fawb tau lees paub tias exogenous S-Abscisic Acid ib leeg... Acid kev kho mob tuaj yeem ua rau kom cov ntsiab lus txo cov suab thaj thiab cov dej soluble, thaum txo cov ntsiab lus titratable acid, txhim kho cov piam thaj-acid piv, thiab txhim kho cov txiv hmab txiv ntoo tsw.
Mechanism of Action: S-Abscisic acid yog ib qho tseem ceeb endogenous hormone regulating grape ripening thiab xim hloov. Nws txhawb nqa cov piam thaj sib xyaw ua ke los ntawm kev tswj cov piam thaj hauv kev thauj mus los, thaum ib txhij ua kom muaj kev qhia ntawm cov noob tseem ceeb hauv txoj hauv kev anthocyanin synthesis, thaum kawg txhawb ripening thiab txhim kho zoo. (International kev tshawb fawb tshawb fawb).
Kev ceev faj rau kev siv: Nws raug nquahu kom txau cov txiv hmab txiv ntoo thaum cov txiv hmab txiv ntoo tau mus txog 20% -30% ripening, nrog rau qhov pom zoo kom pom zoo ntawm 100-200 mg / L. Txau cov bunches zoo dua li txau cov nplooj. Kev siv ntau dhau tuaj yeem ua rau dull thiab tsis muaj xim ntawm daim tawv nqaij, ua rau tsis zoo rau qhov zoo nkauj.
