Photosynthetic Pigments, Energy Distribution, Leaf Anatomy The complex anatomical structure of an intact leaf results in a distribution of photosynthetically active energy between photosynthetic pigments which is different from that observed in isolated chloroplasts. The variance is due mainly to scattering at the gas-liquid interface between cells and intercellular space which tends to increas...

Based on experimental observations made in photosynthetic organ— isms which lacked colored carotenoid pigments, a hypothesis was developed that these pigments could serve as protective agents against photosensi— tized oxidations. Over the last 20 years, many workers have confirmed this hypothesis and have extended the observations to non—photosynthetic bacteria, plants and animals. It has also ...

Extracellular UV-screening pigments gloeocapsin and scytonemin present in the exopolysaccharide (EPS) envelopes of extremophilic cyanobacteria of freshwater and marine environments were studied by Raman spectroscopy and compared to their intracellular photosynthetic pigments. This Raman spectral analysis of the extracellular pigment gloeocapsin showed that it shared Raman spectral signatures wi...

Salinity is one of the most important constrain affecting crop growth and productivity. Hence studying salinity at morphological and biochemical point of view has become the basis for understanding salinity and plant interactions. Under stress, plants survive by enhancing the osmolyte accumulation by complex metabolic activities. Present investigation deals with the effect of salinity on growth...

piriformospora indica, a cultivable root colonizing endophytic fungus of sebacinales, promotes plant growth and confers resistance against biotic and abiotic stress. the fungus has also the ability to colonize the roots of many varieties of plant species. the goal of present study was to clarify the colonization ability of p.indica in artichoke roots and the respond of plant to water stress. re...

biosynthesis of plant pigments is affected by environmental factors especially light intensity. an expriment was conducted to evaluate the effect of different light intensities on photosynthetic and non-photosynthetic pigments of two rose cultivars including ‘red one’ and ‘gulmira’ under greenhouse conditions. in this experiment, the effects of different light intensities including 240, 520 and...

field trials with ficus benjamina l.were conducted at the experimental farm of faculty of agriculture, university azad jiroft in 2012 growth seasons. the aim of this work is to study the effect of foliar application with gibberellic acid (ga3) and benzyladenine (ba) at 0, 100 and 200 mg.l-1 on the vegetative growth and photosynthetic pigments of ficus benjamina plants. the obtained results show...

Field trials with Dizigotheeca elegantissima were conducted at the experimental farm of Faculty of Agriculture, Azad University  Jiroft  in growth seasons of 2012 year. The aim of this work was to study the effect of foliar application of gibberellic acid [GA3] and benzyladenine [BA] at 0, 50, 100 and 150 mgL-1 on the vegetative growth and Photosynthetic pigments ...
