in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

background & aim: the pigments inside the leaf chloroplasts receive sunlight energy and transport it to photosynthesis reaction center. the most important of these pigments is chlorophyll. in this study, the pigments existence in medicinal plant, sumac (rhus coriaria l.), was investigated at biotechnology laboratory, isfahan university of technology. experimental: experiments were performed...

abstract a greenhouse experiment was conducted to study the effects of soil copper (cu) and salinity application on photosynthesis parameters, enzyme activity and anatomical structure of two pistachio cultivars. a factorial greenhouse experiment was carried out as completely randomized design with three replications. treatments consisted of four cu levels (0, 2.5, 5, and 7.5 mg kg-1soil as cuso...

Photosynthesis sustains virtually all life on planet Earth providing the oxygen we breathe and the food we eat; it forms the basis of global food chains and meets the majority of humankind's current energy needs through fossilized photosynthetic fuels. The process of photosynthesis in plants is based on two reactions that are carried out by separate parts of the chloroplast. The light reactions...

The growth of trees and other plants occurs through the interactive combination of photosynthesis and carbon (and other nutrient) assimilation. Photosynthesis enables the production of carbohydrate that can then be used in growing foliage, whereby photosynthesis is enabled. We construct a mathematical model of carbon uptake and storage, which allows the prediction of the growth dynamics of tree...

abstract three pear genotypes (nazkeh, lasoreh and qevilah), grown in 2l containers, were studied under four irrigation regimes in order to evaluate the leaf relative water content (rwc), photosynthesis, leaf gas exchanges and plant dry weight induced by water stress. control treatment everyday was irrigation. irrigation was practiced when soil water potential reached at -0.4, -0.8, and -1.2 mp...

Elements of C4 photosynthesis-a complex adaptation that increases photosynthetic efficiency-may have evolved first to correct an intercellular nitrogen imbalance, and only later evolved a central role in carbon fixation.
