S-Abscisic Acid (S-ABA) yeej pab tau cov txiv pos nphuab ripen thiab qab zib, thaum tseem ua rau cov anthocyanin tsub zuj zuj thiab qab zib cov ntsiab lus. Cov kev tshawb fawb tso cai tau txheeb xyuas nws cov txheej txheem ntawm kev txiav txim:
1. Mechanism of Action
Kev tswj cov piam thaj ntau ntxiv: Kev tshawb fawb los ntawm pab pawg kws tshaj lij ntawm Beijing University of Agriculture tau lees paub tias S-Abscisic Acid (S-ABA) ncaj qha tswj cov piam thaj sib xyaw thaum cov txiv pos nphuab siav dhau los ntawm FaRIPK1-FaTCP7-FaSTP13 / FaSPT molecular module. Thaum lub sij hawm txiv hmab txiv ntoo ripening, S-Abscisic Acid qib nce, relieving inhibition ntawm cov piam thaj thauj noob qhia los ntawm cov teeb liab transduction, activating qab zib cab cov noob caj noob ces, thiab ncaj qha txhawb qab zib tsub zuj zuj ntawm cov txiv hmab txiv ntoo. Qhov no molecularly txheeb xyuas lub luag haujlwm tseem ceeb ntawm ABA hauv kev nce cov ntsiab lus ntawm strawberry qab zib.
Txhawb nqa Anthocyanin Accumulation: S-Abscisic Acid tuaj yeem txhim kho cov synthesis thiab tsub zuj zuj ntawm anthocyanins, thaum tib lub sijhawm tswj hwm qhov sib npaug ntawm cov tshuaj hormones endogenous, yog li txhawb cov txiv pos nphuab xim thiab thaum ntxov ripening, uas ua rau ntau yam xim thiab ua tiav cov xim hloov. Qab Zib lawv tus kheej kuj tuaj yeem ua raws li cov neeg ua ntej thiab cov cim qhia txog cov khoom siv rau anthocyanin synthesis, pab ntxiv rau hauv anthocyanin tsub zuj zuj thiab synergistically txhim kho xim hloov.
2. Daim Ntawv Thov Tus Nqi S-Abscisic acid yog ib qho ntawm tsib yam tshuaj endogenous loj hauv cov nroj tsuag. Dhau li ntawm kev txhim kho xim thiab qab zib, nws tseem tuaj yeem ua rau tib lub sijhawm txhim kho kev ntxhov siab ntawm cov txiv pos nphuab (kev tiv thaiv drought, txias tsis kam, ntsev thiab alkali tsis kam, thiab txo cov tshuaj tua kab thiab chiv puas), txo cov tshuaj tua kab siv, thiab ua kom ruaj khov yields thaum txhawb nqa strawberry zoo txhim kho.
