Eli nqaku liye lahlaziywa ngokuhambelana neenkqubo zokuhlela zeSayensi X kunye nemigaqo-nkqubo.Abahleli bagxininise ezi mpawu zilandelayo ngelixa beqinisekisa ukunyaniseka komxholo:
Uphononongo lwakutsha nje olwenziwa ngabaphandi beYunivesithi yaseOhio State luveze ubudlelwane obuntsonkothileyo phakathi kwabalawuli bokukhula kwezityalo kunye nokumelana ne-creeping bentgrass kuxinzelelo olwahlukeneyo lokusingqongileyo, olufana nobushushu kunye noxinzelelo lwetyuwa.
I-Creeping bentgrass (i-Agrostis stolonifera L.) luhlobo lwengca ye-turfgrass esetyenziswa kakhulu nexabiseke ngokwezoqoqosho esetyenziswa kakhulu kumabala egalufa kulo lonke elaseMelika.Entsimini, izityalo zihlala zisesichengeni soxinzelelo oluninzi ngaxeshanye, kwaye ufundo oluzimeleyo loxinzelelo lusenokungonelanga.Uxinzelelo olunjengoxinzelelo lobushushu kunye noxinzelelo lwetyuwa kunokuchaphazela amanqanaba e-phytohormone, nto leyo inokuchaphazela amandla esityalo ukunyamezela uxinzelelo.
Izazinzulu zenze uluhlu lwezilingo zokuqinisekisa ukuba amanqanaba oxinzelelo lobushushu kunye noxinzelelo lwetyuwa anokuthi abe nefuthe elibi kwimpilo ye-creeping bentgrass, kunye nokuvavanya ukuba ukusetyenziswa kwabalawuli bezityalo kunokuphucula impilo yezityalo phantsi koxinzelelo.Baye bafumanisa ukuba izilawuli ezithile zokukhula kwezityalo zinokuphucula ukunyanyezelwa koxinzelelo lwe-creeping bentgrass, ngakumbi phantsi kobushushu kunye noxinzelelo lwetyuwa.Ezi ziphumo zibonelela ngamathuba okuphuhlisa izicwangciso ezintsha zokunciphisa iziphumo ezibi zoxinzelelo lwendalo kwimpilo ye-turf.
Ukusetyenziswa kwezilawuli ezithile zokukhula kwezityalo kwenza kube lula ukukhulisa ukukhula kunye nophuhliso lwe-creeping bentgrass naphambi koxinzelelo.Oku kufunyenweyo kunesithembiso esikhulu sokuphucula umgangatho we-turf kunye nozinzo phantsi kweemeko ezahlukeneyo zokusingqongileyo.
Olu phononongo luqaqambisa ukusebenzisana okuxhomekeke omnye komnye phakathi kwabalawuli bokukhula kwezityalo kunye noxinzelelo lokusingqongileyo, kuqaqambisa ukuntsokotha kwephysiology ye-turfgrass kunye nokubanakho kweendlela zolawulo ezilungiselelweyo.Olu phando lukwabonelela ngezimvo ezisebenzayo ezinokuthi zibe luncedo ngokuthe ngqo kubaphathi be-turfgrass, i-agronomists, kunye nabachaphazelekayo bendalo.
Ngokutsho kombhali-mbhali u-Arlie Drake, uprofesa oncedisayo wezolimo kwiYunivesithi yaseClark State, "Kuzo zonke izinto esizibeka phezu kweengca, bendisoloko ndicinga ukuba izilawuli zokukhula zilungile, ngakumbi i-HA synthesis inhibitors.Ikakhulu kuba banendima, hayi ukulawula ukukhula ngokuthe nkqo. ”
Umbhali wokugqibela, uDavid Gardner, unjingalwazi wesayensi ye-turf kwiYunivesithi yaseOhio State.Isebenza ikakhulu ekutshatyalalisweni kokhula kwingca kunye nemihombiso, kunye noxinzelelo lwefiziyoloji efana nomthunzi okanye uxinzelelo lobushushu.
Ulwazi oluthe vetshe: U-Arlie Marie Drake et al., Iimpembelelo zokulawula ukukhula kwezityalo kwi-creeping bentgrass phantsi kobushushu, ityuwa kunye noxinzelelo oludibeneyo, i-HortScience (2023).I-DOI: 10.21273/HORTSCI16978-22.
