Photosynthetic responses of different varieties of wheat to high temperature. I. Effect of growth temperature on development and photosynthetic performance


, : Photosynthetic responses of different varieties of wheat to high temperature. I. Effect of growth temperature on development and photosynthetic performance. Journal of Experimental Botany 40(215): 625-631

Both fast and slow chlorophyll fluorescence kinetics were used to assess the differential heat sensitivity of ten wheat (Triticum aestivum L.) varieties commonly grown in northern, temperate or (sub-) tropical climate zones. No consistent differences between the groups were found. Studies on the role of growth temperature in modulating the response of photosynthesis to heat stress were carried out on two of the varieties, APU (Finnish) and K65 (Indian), the former being more sensitive to heat stress. Growth and development of these varieties were similar under both cool (13 degrees C day, 10 degrees C night) and warm (30 degrees C day, 25 degrees C night), regimes. The cool-grown plants exhibited higher rates of net CO2 exchange than the warm-grown plants when expressed on a chlorophyll basis and, in both regimes, photosynthesis declined with age prior to reduction in chlorophyll content. Net CO2 exchange in leaves of K65 showed greater sensitivity to short-term heat stress than APU when plants were grown under the cool regime. Plants grown under the warm regime exhibited an upward shift in the optimum temperature for net CO2 exchange in both varieties, with K65 showing somewhat superior performance at high temperature compared with APU. Stomatal aperture was essentially unaffected by assay temperature during these measurements.
