fenugreek is one of the important medicinal plant that used in the pharmaceutical industry. in order to investigate the effects of salinity stress on relative water content, membrane stability, total chlorophyll, sodium, potassium, sodium to potassium ratio and proline, a factorial experiment was conducted in a completely randomized design with three replications in 2013. experimental treatment...

Introduction Chlorophyll, in various forms, is bound within the living cells of algae, phytoplankton, and other plant matter found in environmental water. Chlorophyll is a key biochemical component in the molecular apparatus that is responsible for photosynthesis, the critical process in which the energy from sunlight is used to produce life-sustaining oxygen. In general, the amount of chloroph...

in the present study, the effects of two arbuscular mycorrhizal fungi, glomus mosseae andglomus intraradices, alone and in combination, on the growth parameters, chlorophyll and the root-rot disease of pea (pisum sativum) caused by fusarium solani f.sp. pisi were evaluated under greenhouse conditions. eight different treatments in four replications were designed in randomized blocks. compared w...

Spatial and temporal variations in canopy structure and leaf biochemistry have considerable influence on fluxes of CO2, water and energy and nutrient cycling in vegetation. Two vegetation indices (VI), NDVI and Macc01, were used to model the spatio-temporal variability of broadleaf chlorophyll content and leaf area index (LAI) across a growing season. Ground data including LAI, hyperspectral le...

A comparison has been made between Signal I, the photo-electron spin resonance signal associated with the primary light conversion act in photosynthesis, and free-radical signals generated in various chlorophyll species in vitro. The esr signals obtained from chlorophyll.monomer, (Chl.L)(+.), chlorophyll dimer, (Chl(2))(+.), and chlorophyll oligomer, (Chl(2))(n) (+.), are broader than Signal I,...

Abstract Determination of chlorophyll content as an indirect method of estimating the productivity of vegetation represents a good way to gain an understanding of the photosynthetic regime of plants. Physiological investigations of chlorophyll and carotenoid content in the uppermost internode of several wheat cultivars were carried out at the outset of the flowering phase. The dependence of chl...
