Agricultural practices determine the level of food production and, to great extent, the state of the global environment. During the last decades, the indiscriminate recourse to fertilizers as well as the nitrogen losses from land application have been recognized as serious issues of modern agriculture, globally contributing to nitrate pollution. The development of a reliable Near-Infra-Red Spec...

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...

Passive optical hyperspectral remote sensing of plant pigments offers potential for understanding plant ecophysiological processes across a range of spatial scales. Following a number of decades of research in this field, this paper undertakes a systematic meta-analysis of 85 articles to determine whether passive optical hyperspectral remote sensing techniques are sufficiently well developed to...

The present investigation envisages the in vivo measured laser induced chlorophyll florescence spectra of EMS (Ethyl methane sulphonate) treated safflower leaves. Seeds of safflower were treated with 0.5% EMS for three treatment durations (3h, 5h and 7h) to raise the populations. The effect of EMS treatment on chlorophyll content in the leaves was assessed using laser induced chlorophyll fluore...

Photosynthetic pigments in a warm core eddy of the East Australian Current were studied by In vjvo fluorometry, spectrophotometry and thin-layer chromatography. The Variosens i n sltu fluorometer gave only an approximate guide to the location and quantity of phytoplankton in the water column; spectrophotometric curve analysis revealed the presence of intact or detrital chlorophylls, and quantit...

Chlorophyll-protein complexes and electron transport activities were measured during iron nutrition-mediated chloroplast development in sugar beet (Beta vulgaris L. cv F58-554H1). Results showed that the chlorophyll-protein complexes associated with the reaction centers of photosystem I (CP1) and photosystem II (CPa) and the electron transport activities of these two photosystems per leaf area ...

abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...

Chlorophyll a concentration and nutrient concentrations were measured at depths along water columns under aerated and ...
