Eli nqaku liphononongwe ngokweenkqubo kunye nemigaqo-nkqubo yokuhlela yeSayensi X. Abahleli bagxininise ezi mpawu zilandelayo ngelixa beqinisekisa ukuthembeka komxholo:
Uphando lwakutshanje olwenziwe ngabaphandi beYunivesithi yaseOhio State lutyhile ubudlelwane obunzima phakathi kwabalawuli bokukhula kwezityalo kunye nokumelana kwe-creeping bentgrass kwiingcinezelo ezahlukeneyo zokusingqongileyo, ezinje ngoxinzelelo lobushushu kunye netyuwa.
I-Creeping bentgrass (Agrostis stolonifera L.) luhlobo lwe-turfgrass olusetyenziswa kakhulu nolunexabiso kwezoqoqosho olusetyenziswa kakhulu kwiindawo zegalufa kulo lonke elase-United States. Entsimini, izityalo zihlala zijongene noxinzelelo oluninzi ngaxeshanye, kwaye uphando oluzimeleyo loxinzelelo lusenokunganeli. Uxinzelelo olufana noxinzelelo lobushushu kunye noxinzelelo lwetyuwa lunokuchaphazela amanqanaba e-phytohormone, nto leyo enokuchaphazela amandla esityalo okunyamezela uxinzelelo.
Izazinzulu zenze uthotho lweemvavanyo ukuze zifumanise ukuba amanqanaba oxinzelelo lobushushu kunye noxinzelelo lwetyuwa anokuchaphazela kakubi impilo ye-creeping bentgrass, kwaye zihlole ukuba ukusetyenziswa kwezixhobo zokulawula ukukhula kwezityalo kunokuphucula impilo yezityalo phantsi koxinzelelo. Zifumanise ukuba izixhobo ezithile zokulawula ukukhula kwezityalo zinokuphucula ukunyamezela uxinzelelo lwe-creeping bentgrass, ingakumbi phantsi koxinzelelo lobushushu kunye netyuwa. Ezi ziphumo zibonelela ngamathuba okuphuhlisa amaqhinga amatsha okunciphisa iziphumo ezimbi zoxinzelelo lokusingqongileyo kwimpilo yengca.
Ukusetyenziswa kwezixhobo ezithile zokulawula ukukhula kwezityalo kwenza kube nokwenzeka ukuphucula ukukhula nophuhliso lwe-creeping bentgrass nokuba kukho izinto ezibangela uxinezeleko. Olu fumaniso lunesithembiso esikhulu sokuphucula umgangatho wengca kunye nokuzinza phantsi kweemeko ezahlukeneyo zokusingqongileyo.
Olu phononongo lubonisa unxibelelwano oluxhomekeke phakathi kwabalawuli bokukhula kwezityalo kunye nabaxinzeleli bokusingqongileyo, lugxininisa ubunzima be-physiology ye-turfgrass kunye nokukwazi kweendlela zolawulo ezilungiselelweyo. Olu phando lukwabonelela ngengqiqo esebenzayo enokuba luncedo ngokuthe ngqo kubaphathi be-turfgrass, iingcali zezolimo, kunye nabachaphazelekayo kwindalo.
Ngokutsho kombhali-mbhali u-Arlie Drake, uprofesa oncedisayo wezolimo kwiYunivesithi yaseClark State, “Kuzo zonke izinto esizibeka ezingcani, bendisoloko ndicinga ukuba abalawuli bokukhula balungile, ingakumbi izithinteli zokwenziwa kwe-HA. Ngokuyintloko kuba nazo zinendima, kungekuphela nje ekulawuleni ukukhula ngokuthe nkqo.”
Umbhali wokugqibela, uDavid Gardner, nguprofesa wesayensi yengca kwiYunivesithi yaseOhio State. Isebenza ikakhulu ekulawuleni ukhula kwiingca kunye nezinto zokuhombisa, kunye ne-physiology yoxinzelelo efana nomthunzi okanye uxinzelelo lobushushu.
