Impact of Higher Carbon Dioxide Concentrations and Elevated Temperatures on the Growth of Field Bindweed (Convolvulus arvensis L.) in Turkey
(Tarbiat Modares Univ, 2024) Karaman, Y.; Tursun, N.; Uludag, A.
Field bindweed (Convolvulus arvensis L.) is one of the worst weeds in Turkey as well as worldwide. Climate change, with increasing temperature and concentrations of greenhouse gases and unpredictable extreme weather events, has been among the foremost problems of the world. The effect of climate change on crop husbandry and weeds is to be investigated. The effect of rising temperature and CO2 on different populations of C. arvensis was studied under greenhouse conditions in the Malatya Province of Turkey, in 2019. For this study, the weed seeds were collected from 14 provinces throughout Turkey during 2018. Two temperature regimes (day/night 26/16 degrees C and 29/19 degrees C) and two CO2 levels (400 +/- 50 and 800 +/- 50 ppm) were used. Plant aboveground length, root length, and dry weights of root, aboveground parts, and total plant were not affected by temperature, CO2, and seed source. However, seed source affected root length differently depending on temperature and root length, and root dry weight as affected by CO2 level. In addition, seed source and temperature showed significant effect on measured parameters, while no significant effect was determined for CO2.
