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 کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولTemperature acclimation of photosynthesis and respiration: A key uncertainty in the carbon cycle-climate feedback
Earth System Models typically use static responses to temperature to calculate photosynthesis and respiration, but experimental evidence suggests that many plants acclimate to prevailing temperatures. We incorporated representations of photosynthetic and leaf respiratory temperature acclimation into the Community Land Model, the terrestrial component of the Community Earth System Model. These p...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولAcclimation 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...
