growth, leaf gas exchange, and chlorophyll fluorescence responses of two cultivars of salix integra thunb. to waterlogging stress
salix integra thunb. is a shrub distributed in china along the huai river riparian zone, and plays an important role in water and soil conservation. s. integra shrub land is easily submerged during july to october due to the flooding of huai river. in order to characterize the physiological mechanisms of waterlogging tolerance of s. integra and to help rationally select waterlogging-tolerant sp...
متن کاملAssessing the Effects of Water Deficit on Photosynthesis Using Parameters Derived from Measurements of Leaf Gas Exchange and of Chlorophyll a Fluorescence
Water deficit (WD) is expected to increase in intensity, frequency and duration in many parts of the world as a consequence of global change, with potential negative effects on plant gas exchange and growth. We review here the parameters that can be derived from measurements made on leaves, in the field, and that can be used to assess the effects of WD on the components of plant photosynthetic ...
متن کاملChlorophyll Fluorescence Parameters and Chlorophyll Content in Mangrove Species Grown in Different Salinity
Leaf chlorophyll fluorescence parameters as well as chlorophyll content were compared in three dominant mangrove species grown in two zones with different salinity in the Bhitarakanika National Park. The accumulation of dry matter and chlorophyll content in leaves decreased under high saline conditions. Quantification and de-convolution of chlorophyll fluo-rescence transient into several phenom...
متن کاملhazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Chlorophyll Fluorescence: A Novel Method to Screen for Herbicide Resistance
The susceptibility to Terbacil of six randomly selected strawberry cultivars (‘Aromas’, ‘Chambly’, ‘Harmonie’, ‘Kent’, ‘La Clé des Champs’ and ‘Seascape’) was analysed using chlorophyll florescence (CF) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. Terbacil was applied at one of five rates...
