Acclimation of photosynthesis to low leaf water potentials.
Photosynthesis is reduced at low leaf water potentials (Psi(l)) but repeated water deficits can decrease this reduction, resulting in photosynthetic acclimation. The contribution of the stomata and the chloroplasts to this acclimation is unknown. We evaluated stomatal and chloroplast contributions when soil-grown sunflower (Helianthus annuus L.) plants were subjected to water deficit pretreatme...
متن کاملTemperature acclimation of photosynthesis and related changes in photosystem II electron transport in winter wheat.
Winter wheat (Triticum aestivum L. cv Norin No. 61) was grown at 25 degrees C until the third leaves reached about 10 cm in length and then at 15 degrees C, 25 degrees C, or 35 degrees C until full development of the third leaves (about 1 week at 25 degrees C, but 2-3 weeks at 15 degrees C or 35 degrees C). In the leaves developed at 15 degrees C, 25 degrees C, and 35 degrees C, the optimum tem...
متن کاملAcclimation of adrenalectomized rats to low environmental temperature.
EVERAL authors have interpreted the S adrenal hyperactivity of normal animals exposed to low temperatures (1, 2) and the reduced cold resistance of adrenalectomized animals (3-5), as indications of the importance of the adrenal glands in the acquisition of resistance to low temperatures. However, in studies on acclimation to other types of stressing conditions (6, 7) it has been found that adre...
متن کاملAcclimation of photosynthesis to light and canopy nitrogen distribution: an interpretation.
BACKGROUND AND AIMS Acclimation of photosynthesis to light and its connection with canopy nitrogen (N) distribution are considered. An interpretation of a proportionality between light-saturated photosynthesis and local averaged leaf irradiance is proposed by means of a simple model. MODEL The model assumes (a) local irradiance drives synthesis of photosynthetic protein from metabolic N; (b) ...
متن کاملTemperature acclimation of photosynthesis: mechanisms involved in the changes in temperature dependence of photosynthetic rate.
Growth temperature alters temperature dependence of the photosynthetic rate (temperature acclimation). In many species, the optimal temperature that maximizes the photosynthetic rate increases with increasing growth temperature. In this minireview, mechanisms involved in changes in the photosynthesis-temperature curve are discussed. Based on the biochemical model of photosynthesis, change in th...
