IYunivesithi yaseYunivesithi, ePennsylvania — Ingqolowa yasebusika ikhuliswa kakhulu kwiifama zeenkukhu kummandla weMid-Atlantic eMelika ukuze kuveliseke iinkozo kunye neengca. Ingqolowa isetyenziswa njengokutya kwezilwanyana, kwaye ingca isetyenziswa njengomandlalo.Ukusetyenziswa kwabalawuli bokukhulainokunyusa isivuno sengqolowa ngokunciphisa ukukhula ngokuthe nkqo nokunciphisa umngcipheko wokuhlala, imeko enciphisa kakhulu isivuno sengqolowa. Nangona kunjalo, impembelelo yabalawuli bokukhula kwisivuno kunye nomgangatho wengca ayicacanga. Ke ngoko, iqela lophando elivela kwiYunivesithi yasePennsylvania State lenze uphando lokuvavanya iziphumo zokudibanisa abalawuli bokukhula kunye namazinga ahlukeneyo okusetyenziswa kwesichumiso se-nitrogen. Olu phononongo lwenziwe kuvavanyo lwentsimi yengqolowa yasebusika kwiZiko loPhando lwezoLimo laseRussell E. Larson kwiYunivesithi yasePennsylvania State.
"Abalimi abafuni ukuba ingqolowa ikhule kakhulu ize ihlale, nto leyo eyonakalisa iinkozo, ngoko ke abalimi abaninzi kudala beyisebenzisa."abalawuli bokukhula kwezityalo,"Utsho uDaniela Carrijo, uprofesa oncedisayo wemveliso yengqolowa kunye neengcali zokwandisa izityalo kwiKholeji yeSayensi yezoLimo kwiYunivesithi yasePennsylvania State. "Siyazi ukuba abalawuli bokukhula kwezityalo banokunciphisa umngcipheko wokuhlaliswa kwaye bandise isivuno sengqolowa, kodwa abalimi kunye nabanye abachaphazelekayo bafuna ukwazi impembelelo yabo kwisivuno kunye nomgangatho wengca. Le yiprojekthi enemiphumo ebonakalayo, kwaye sivavanye imveliso esetyenziswa rhoqo ebizwa ngokuba yi-triccyclazole ethyl ester ukuze sifumanise impembelelo yayo kwisivuno kunye nomgangatho wengca, nto leyo ikwabalulekile kwiifama ezixutyiweyo."
Kwiminyaka engaphezu kwemibini, abaphandi bavavanya iindibaniselwano ezilithoba zamanqanaba amathathu okusetyenziswa kwesichumisi se-nitrogen kunye nonyango lwe-tricyclazole ethyl ester ezintathu. Bafumanise ukuba i-tricyclazole ethyl ester inciphise ubude besityalo kodwa ayizange yonyuse ubukhulu besiqu. Unyango lwe-tricyclazole ethyl ester ezimbini lubangele ukwehla kwe-8% kwisivuno se-straw, ngelixa unyango olunye lunciphise isivuno se-straw nge-5%, nangona lo mahluko wawungabalulekanga ngokwezibalo. Bafumanise nokuba i-tricyclazole ethyl ester ayizange itshintshe umgangatho we-straw okanye ukufunxwa kwamanzi—oko kuthetha ukuba ayizange ichaphazele amandla e-straw okugcina amanzi, ngoko ke i-straw isenokusetyenziswa njengebhedi yezilwanyana. Abaphandi baxele ukuba ukuhlala akuzange kubonwe nakweyiphi na iploti yovavanyo, kwaye ukuba ukwanda kokusetyenziswa kwesichumisi se-nitrogen kuphucule umxholo weprotheyini yengqolowa.
"Iziphumo zethu zixubile—sifumanise ukuba i-tricyclazole ethyl ester inokunciphisa kancinci isivuno sengca, kodwa ayichaphazeli umgangatho wengca okanye isivuno sengqolowa," utshilo uCarrijo. "Abalimi abasebenzisa i-tricyclazole ethyl ester kufuneka bajonge izinto ezilungileyo nezingalunganga: inokunceda ukunciphisa ukuhla (ukuba oku kuyingxaki), kodwa inokunciphisa kancinci isivuno sengca. Olu tshintshiselwano lubaluleke kakhulu ukuba ingca yimveliso ebalulekileyo yefama kwaye isetyenziswa njengebhedi."
Umbhali wokuqala wolu phando, uLarissa Correa, wayengumntu ophandayo otyeleleyo kwiSebe leSayensi yeZityalo kwiYunivesithi yasePennsylvania State. Okwangoku ungumfundi ophumelele kwizifundo zobugqirha kwiYunivesithi yaseWisconsin-Madison. URonald Hoover, umlawuli wenkqubo edibeneyo kwiSebe leSayensi yeZityalo, naye uthathile inxaxheba kolu phando.
Olu phando luxhaswe yiSyngenta kunye ne-US Department of Agriculture's National Institute of Food and Agriculture.
