Tsab xov xwm no tau raug tshuaj xyuas raws li Science X cov txheej txheem kho thiab cov cai. Cov neeg kho tau hais txog cov yam ntxwv hauv qab no thaum ua kom ntseeg tau tias cov ntsiab lus muaj kev ncaj ncees:
Tsis ntev los no, cov kws tshawb fawb ntawm Ohio State University tau qhia txog kev sib raug zoo ntawm cov nroj tsuag uas tswj kev loj hlob thiab kev tiv thaiv ntawm cov nyom bentgrass rau ntau yam kev ntxhov siab ntawm ib puag ncig, xws li cua sov thiab ntsev.
Cov nyom nyom uas loj hlob sai (Agrostis stolonifera L.) yog ib hom nyom uas siv dav thiab muaj nqis heev uas siv dav hauv cov chaw ua si golf thoob plaws Tebchaws Meskas. Hauv thaj teb, cov nroj tsuag feem ntau raug ntau yam kev ntxhov siab tib lub sijhawm, thiab kev tshawb fawb ywj pheej ntawm kev ntxhov siab yuav tsis txaus. Kev ntxhov siab xws li kev ntxhov siab kub thiab kev ntxhov siab ntsev tuaj yeem cuam tshuam rau cov theem phytohormone, uas tuaj yeem cuam tshuam rau cov nroj tsuag lub peev xwm los tiv taus kev ntxhov siab.
Cov kws tshawb fawb tau ua ntau yam kev sim los txiav txim seb qib kev ntxhov siab ntawm cua sov thiab kev ntxhov siab ntawm ntsev puas tuaj yeem cuam tshuam tsis zoo rau kev noj qab haus huv ntawm cov nyom bentgrass, thiab los soj ntsuam seb kev siv cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag puas tuaj yeem txhim kho kev noj qab haus huv ntawm cov nroj tsuag hauv qab kev ntxhov siab. Lawv pom tias qee cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag tuaj yeem txhim kho kev kam rau kev ntxhov siab ntawm cov nyom bentgrass, tshwj xeeb tshaj yog nyob rau hauv cua sov thiab kev ntxhov siab ntawm ntsev. Cov txiaj ntsig no muab cov sijhawm rau kev tsim cov tswv yim tshiab los txo cov teebmeem tsis zoo ntawm cov kev ntxhov siab ntawm ib puag ncig rau kev noj qab haus huv ntawm cov nyom.
Kev siv cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag ua rau nws muaj peev xwm ua kom zoo tshaj plaws kev loj hlob thiab kev txhim kho ntawm cov nyom bentgrass txawm tias muaj kev ntxhov siab. Qhov kev tshawb pom no muaj kev cog lus zoo rau kev txhim kho qhov zoo ntawm cov nyom thiab kev ruaj khov nyob rau hauv ntau yam xwm txheej ib puag ncig.
Daim ntawv tshawb fawb no qhia txog kev sib cuam tshuam ntawm cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag thiab cov teeb meem ib puag ncig, qhia txog qhov nyuaj ntawm kev ua haujlwm ntawm cov nyom turfgrass thiab lub peev xwm ntawm cov txheej txheem tswj hwm uas tsim nyog. Daim ntawv tshawb fawb no kuj muab cov kev nkag siab zoo uas tuaj yeem pab tau ncaj qha rau cov thawj coj nyom turfgrass, cov kws tshaj lij agronomists, thiab cov neeg koom nrog ib puag ncig.
Raws li tus sau ntawv Arlie Drake, tus pab xibfwb qhia txog kev ua liaj ua teb ntawm Clark State University, "Ntawm txhua yam khoom uas peb muab tso rau ntawm cov nyom, kuv ib txwm xav tias cov tshuaj tswj kev loj hlob zoo, tshwj xeeb tshaj yog HA synthesis inhibitors. Feem ntau vim lawv kuj muaj lub luag haujlwm, tsis yog tsuas yog tswj kev loj hlob ntsug xwb."
Tus sau kawg, David Gardner, yog ib tug xibfwb qhia txog kev tshawb fawb txog cov nyom ntawm Ohio State University. Nws ua haujlwm feem ntau rau kev tswj cov nyom hauv cov nyom thiab cov khoom dai kom zoo nkauj, nrog rau kev ntxhov siab ntawm lub cev xws li qhov ntxoov ntxoo lossis kev ntxhov siab kub.
