Study the photosynthetic pigments and phenolic compounds of safflower in response to foliar application of melatonin under water deficit condition
In order to study the effect of melatonin foliar application on photosynthetic pigments’ composition, phenolic compounds and soluble sugars on plants grown from different seed quality of safflower under water deficit condition, two field trials were conducted at Aburaihan Campus, University of Tehran in 2017 and 2018 growing seasons. The experimantal design was split-factorial randomized comple...
متن کاملRegulation of Photosynthetic Rate of Two Sunflower Hybrids under Water Stress.
The effect of short-term water stress on photosynthesis of two sunflower hybrids (Helianthus annuus L. cv Sungro-380 and cv SH-3622), differing in productivity under field conditions, was measured. The rate of CO(2) assimilation of young, mature leaves of SH-3622 under well-watered conditions was approximately 30% greater than that of Sungro-380 in bright light and elevated CO(2); the carboxyla...
متن کاملTranscription factors and regulation of photosynthetic and related metabolism under environmental stresses.
BACKGROUND Environmental conditions, such as water supply, temperature and salinity, strongly affect plant growth and development. Extremes of these conditions (abiotic stresses) adversely affect many different mechanisms associated with plant responses and adaptation to stress: photosynthetic mechanisms, e.g. stomatal control of CO(2) diffusion, photosystem II repair, ribulose bisphosphate car...
متن کاملproficiency level and factors fostering reticence in efl learners
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
15 صفحه اولsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
