Abstract
There is little scientific information on the response of C3 plants such as table beet (Beta vulgaris L.) under future scenarios caused by climate change. The present study aimed to evaluate the effect of CO2 concentration on the morphometric, physiological variables, and yield of table beet plants exposed to different CO2 concentrations. The research was conducted in the experimental greenhouse built by the Automation and Control Research Group at the University of Pamplona. An experiment was carried out under controlled conditions with a completely randomized design to evaluate the influence on the morphometric, physiological, and yield variables of beet plants under different CO2 concentrations. High CO2 concentration had a significant influence on plant height and the number of leaves at the end of the cultivation cycle, while leaf surface area and plant leaf area were significantly influenced at the beginning of the cultivation cycle, but not at 45 days. Conversely, the chlorophyll index was lower at 45 days for the high CO2 concentration treatment. Although no significant differences were observed in the green weight of the leaf area and leaf dry matter, there was a marked and significant difference in yield levels, indicating that the accumulation of reserves in beet plants was influenced by the higher CO2 concentration.
