Nowadays, heavy metal pollution has become a serious environmental problem on global scale. The heavy metals are non-biodegradable in nature, which can easily accumulate in the organisms of lower trophic level, and enter to the human body system through food chain. From this backdrop, the present experiment highlighted the effect of three heavy metals (Cr, Pb, and Mn) in different concentration...

A trial for estimating leaf chlorophyll content based on leaf reflectance was conducted for three major plant species in Daegu, South Korea. To estimate the chlorophyll content in a leaf, we measured the leaf elongation and related the leaf reflectance to its absorbance. Leaves of the target species were found to start elongating around the middle of April and continued elongation until the mid...

The use of fluorescence induction measurements in leaves infiltrated with 3-(3,4-dichlorophenyl)-1,1-dimethylurea has been evaluated as a routine method for estimation of the concentration of the reaction centers of photosystem II relative to total chlorophyll in a wide variety of plant species. The procedure is based on a simple theory that takes into account the attenuation of light in passin...

Response of winter wheat (Triticum aestivum L.) spectral reflectance characteristics to chlorophyll content in planting densities application rate. Bulg. J. Agric. Sci., 19: 1190-1197 The leaf chlorophyll content of wheat is one of important agronomic parameters to anal...

Twenty six accessions of grain Amaranth (Amaranthus hypochondriacus L.) were evaluated for salient biochemical and quantitative traits particularly reference to chlorophyll a and b, total chlorophyll, phenol content, leaf moisture, leaf protein content, test weight and yield plant. Genetic divergence and association among these traits were analysed. Chlorophyll a, chlorophyll b, total chlorophy...

rice (oryza sativa), a salt-sensitive species, has considerable genetic variation for salt tolerance within cultivars. to evaluate salinity effects on growth, chlorophyll content and ion uptake of two rice genotypes (ir29 and ir651, sensitive and tolerant respectively) accompany with two semi-tolerant iranian rice cultivars in a green house experiment were grown in normal condition till 6th lea...

The seasonal changes of leaf physiological traits and its relationship with abiotic factors (photosynthetic active radiation-PAR, leaf temperature-Tleaf, air temperature-Tair, Tleaf - Tair- ΔT) were studied on sugar beets grown under the semi-arid conditions of central Greece. Sugar beet (Beta vulgaris L.) cv Rizor was established in a Randomised Complete Block design experiment for two years (...
