Lesi sihloko sibuyekezwe ngokuhambisana nezinqubo nezinqubomgomo zokuhlela zeSayensi X. Abahleli bagcizelele lezi zimfanelo ezilandelayo ngenkathi beqinisekisa ubuqotho bokuqukethwe:
Ucwaningo lwamuva olwenziwe abacwaningi base-Ohio State University luveze ubudlelwano obuyinkimbinkimbi phakathi kwabalawuli bokukhula kwezitshalo kanye nokumelana kwe-bentgrass ekhasa phansi ezingcindezini ezahlukene zemvelo, njengokucindezeleka kokushisa nosawoti.
I-Creeping bentgrass (i-Agrostis stolonifera L.) uhlobo lwe-turfgrass olusetshenziswa kabanzi futhi oluwusizo kwezomnotho olusetshenziswa kabanzi ezinkundleni zegalofu kulo lonke elase-United States. Ensimini, izitshalo zivame ukuchayeka ezingcindezini eziningi ngesikhathi esisodwa, futhi ucwaningo oluzimele lwezingcindezi lungase lunganeli. Izingcindezi ezifana nokucindezeleka kokushisa kanye nokucindezeleka kosawoti zingathinta amazinga e-phytohormone, okungathinta ikhono lesitshalo lokubekezelela ukucindezeleka.
Ososayensi benze uchungechunge lwezivivinyo ukuze bathole ukuthi amazinga okucindezeleka kokushisa kanye nokucindezeleka kukasawoti kungayithinta kabi yini impilo ye-creeping bentgrass, kanye nokuhlola ukuthi ukusetshenziswa kwe-plant growth controls kungathuthukisa yini impilo yezitshalo ngaphansi kokucindezeleka. Bathole ukuthi ezinye i-plant growth controls zingathuthukisa ukubekezelela ukucindezeleka kwe-creeping bentgrass, ikakhulukazi ngaphansi kokucindezeleka kokushisa kanye nosawoti. Le miphumela inikeza amathuba okuthuthukisa amasu amasha okunciphisa imiphumela emibi ye-environmental stress empilweni yotshani.
Ukusetshenziswa kwezindlela ezithile zokulawula ukukhula kwezitshalo kwenza kube nokwenzeka ukuthuthukisa ukukhula nokuthuthukiswa kwe-bentgrass enwabuzelayo ngisho nalapho kukhona izinto ezibangela ukucindezeleka. Lokhu kutholwa kunesithembiso esikhulu sokuthuthukisa ikhwalithi yotshani kanye nokusimama ngaphansi kwezimo ezahlukene zemvelo.
Lolu cwaningo luqokomisa ukusebenzisana okuncikene phakathi kwabalawuli bokukhula kwezitshalo kanye nabacindezeli bemvelo, luqokomisa ubunzima be-physiology ye-turfgrass kanye nekhono lezindlela zokuphatha ezilungiselelwe. Lolu cwaningo luphinde lunikeze ukuqonda okusebenzayo okungazuzisa ngqo abaphathi be-turfgrass, izazi zezolimo, kanye nabathintekayo bezemvelo.
Ngokusho kombhali-mbhali u-Arlie Drake, uprofesa osizayo wezolimo eClark State University, “Kuzo zonke izinto esizifaka otshanini, bengilokhu ngicabanga ukuthi abalawuli bokukhula balungile, ikakhulukazi abavimbeli bokwenziwa kwe-HA. Ikakhulukazi ngoba banendima, hhayi nje ukulawula ukukhula okuqondile.”
Umbhali wokugcina, uDavid Gardner, unguprofesa wesayensi yotshani e-Ohio State University. Isebenza kakhulu ekulawuleni ukhula emagatsheni nasezindaweni zokuhlobisa, kanye ne-physiology yokucindezeleka njengomthunzi noma ukucindezeleka kokushisa.
Ulwazi olwengeziwe: U-Arlie Marie Drake nabanye, Imiphumela yabalawuli bokukhula kwezitshalo otshanini obuhambayo obugobile ngaphansi kokushisa, usawoti kanye nokucindezeleka okuhlangene, i-HortScience (2023). I-DOI: 10.21273/HORTSCI16978-22.
Uma uhlangabezana nokubhala iphutha, ukungalungi, noma ungathanda ukuhambisa isicelo sokuhlela okuqukethwe kuleli khasi, sicela usebenzise leli fomu. Ngemibuzo ejwayelekile, sicela usebenzise ifomu lethu lokuxhumana. Ukuze uthole impendulo ejwayelekile, sebenzisa isigaba sokuphawula komphakathi esingezansi (landela iziqondiso).
Impendulo yakho ibaluleke kakhulu kithi. Kodwa-ke, ngenxa yobuningi bemiyalezo, asikwazi ukuqinisekisa impendulo yomuntu siqu.
Ikheli lakho le-imeyili lisetshenziselwa kuphela ukutshela abamukeli ukuthi ngubani othumele i-imeyili. Ikheli lakho noma ikheli lomamukeli ngeke lisetshenziswe nganoma iyiphi enye injongo. Ulwazi olufakayo luzovela ku-imeyili yakho futhi ngeke lugcinwe kunoma yiliphi ifomu yi-Phys.org.
Thola izibuyekezo zamasonto onke kanye/noma zansuku zonke ebhokisini lakho lokungenayo. Ungazikhipha ohlwini nganoma yisiphi isikhathi futhi ngeke sabelane ngemininingwane yakho nabantu besithathu.
Senza okuqukethwe kwethu kufinyeleleke kuwo wonke umuntu. Cabanga ngokusekela umgomo weSayensi X nge-akhawunti ye-premium.
