Abstract
There are few research results on the behavior of C3 plants such as pea (Pisum sativum L.) in future climate change scenarios. The objective of the present research was to evaluate the influence of CO2 concentration on morphometric and physiological variables, and pea yields under greenhouse conditions in Pamplona Norte de Santander. The research was carried out in an automated experimental greenhouse with two cubicles, one of which worked with a CO2 concentration of 1300 ppm. And in the other 600 ppm. Morphometric and physiological variables were evaluated up to 42 days after the plants of the Santa Isabel variety were planted and at 95 days the variables pod number, number of grains and grain weight were evaluated. Significant increases were verified in height, number of leaves, number of lateral shoots and leaf surface in the pea crop at an early stage of development, but not in stem diameter and chlorophyll index. A higher concentration of CO2 influenced an increase in the leaf area of pea plants in the initial stage of crop development, which was reflected in a greater number of pods, grain number and grain weight.
