0.03% S-abscisic acid (S-ABA) aqueous tov zoo tswj cov nplej loj hlob, txhawb kev loj hlob hauv paus, nce panicle hnyav, thiab boosts yield. Kev txheeb xyuas pej xeem cov txiaj ntsig tau nce los ntawm kwv yees li 7.8% mus rau 11.1%, nrog cov txiaj ntsig tseem ceeb dua tau pom nyob rau hauv cov ntsev ntsev.
Core Mechanisms of Action
S-abscisic acid yog lub npe hu ua "kev loj hlob-ntsuas qhov tseem ceeb" thiab "kev ntxhov siab-ua haujlwm inducing factor" rau mov. Nws cov haujlwm tseem ceeb tshwm sim hauv ob txoj hauv kev:
Txoj Cai Loj Hlob: Nws sib npaug endogenous hormone metabolism, txhawb kev loj hlob hauv paus, txhim kho cov yub lub peev xwm nqus dej thiab cov as-ham, thiab txhawb nqa cov qoob loo zoo. Nws kuj sib npaug cov nroj tsuag thiab kev loj hlob ntawm cov me nyuam, txhawb txoj kev loj hlob ntawm cov khoom tillers thaum txo cov tsis muaj txiaj ntsig.
Ua kom muaj kev ntxhov siab: Ua raws li tus neeg xa xov xwm uas ua rau muaj kev cuam tshuam ntawm cov noob kev ntxhov siab, nws ua rau cov nplej cog cov kev ntxhov siab-tiv thaiv kab mob. Qhov no txhim khu kev ua siab ntev rau drought, kub kub, txias, salinity, thiab kab mob, yog li txo qhov kev loj hlob inhibition tshwm sim los ntawm ib puag ncig tsis zoo thiab ua kom ruaj khov yields.
Cov txiaj ntsig tshwj xeeb ntawm S-abscisic Acid ntawm Rice Roots thiab Panicle Nyhav
Txhawb kev loj hlob hauv paus: noob soaking ua ntej sowing ncaj qha txhawb kev loj hlob hauv paus thiab txhim kho cov peev xwm nqus cov as-ham. Qhov no shortens lub sij hawm rov qab tom qab transplanting, cia seedlings nkag mus rau lub zoo li qub theem sai sai. Nyob rau hauv ntsev kev nyuaj siab, nws tswj cov hauv paus vitality, kom ntseeg tau ntxiv nutrient uptake.
Nce Panicle Nyhav thiab Yield: Nws txhim kho cov noob-tso tus nqi, nce 1,000-grain hnyav, txo spikelet degeneration, thiab txhim kho cov nplej filling, thaum kawg ua rau ntau dua yields. Cov ntaub ntawv tshawb fawb pej xeem qhia tau hais tias nyob rau hauv ib txwm muaj kev cog qoob loo, kev siv S-ABA ntawm hybrid nplej tuaj yeem nce yields los ntawm 7.8% -11.1%. Hauv thaj chaw ntsev ntsev, nws txo qis qhov cuam tshuam inhibitory ntawm salinity ntawm tus naj npawb ntawm cov khoom lag luam panicles thiab cov noob-tso tus nqi, yog li khaws cia lossis nce cov qoob loo - nrog nce ntau tshaj 14% hauv qee kis. Cov lus qhia rau kev siv S-abscisic acid (rau regulating mov loj hlob)
Cov khoom no feem ntau yog siv rau soaking noob nplej ua ntej sowing. Dilute cov khoom mus rau ib tug concentration ntawm 1: 750-1: 1000 raws li tau teev tseg, thiab tsau cov noob ntawm ambient kub rau 24-36 teev, kom ntseeg tau tias cov dej theem yog txaus kom tag nrho submerge lawv. Tom qab soaking, yaug cov noob nrog dej huv, tom qab ntawd mus rau txheej txheem germination thiab sowing txheej txheem.
