Total chlorophyll content changes under elevated CO2. Effects of different levels of carbon dioxide (CO2) and temperatures (oC) on total chlorophyll content (mg. g−1fresh weight) of the two germplasm of Bhut Jolokia subjected to different treatments. Different treatments given were: CTGT I (380 ppm CO2 + ambient temperature), CTGT II (550 ppm CO2 + 2 °C higher than ambient from flower bud initiation till maturity) and CTGT III (750 ppm CO2 + 4 °C higher than ambient from flower bud initiation till maturity), normal field conditions. Bars with different letters are statistically different from each other (n = 6)
