water deficit stress is the most important environmental constraint for growth, yield and productivity of crops, including the oil seed crops. this study was aimed at studying the influence of differing irrigation régimes on growth, chlorophyll , proline and some antioxidants content along with grain yield, yield components and oil content of sesame genotypes using a 4-replicate split plot rand...

in order to evaluate the morphological changes of rice seedlings (variety of neda and fajr) under salinity management in 1394 was conducted in islamic azad university, ayatollah amoli. this factorial experiment in a completely randomized design with two genotypes (varieties neda and fajr) in four salinity levels (zero, 40, 80 and 120 mm sodium chloride) and was performed in triplicate. results ...

Iron deficiency in plants is caused by a low availability of iron in the soil, and its main visual symptom is leaf yellowing due to a decrease in chlorophyll content, along with a reduction in plant growth and fruit quality. Foliar sprays with Fe compounds are an economic alternative to the treatment with expensive synthetic Fe-chelates applied to the soil, although the efficacy of foliar treat...

We estimated the light use efficiency (LUE) via vegetation canopy chlorophyll content (CCCcanopy) based on in situ measurements of spectral reflectance, biophysical characteristics, ecosystem CO 2 fluxes and micrometeorological factors over a maize canopy in Northeast China. The results showed that among the common chlorophyll-related vegetation indices (VIs), CCCcanopy had the most obviously e...

studying the physiological responses of linseed genotypes to water deficit stress may be helpful in recognizing the linseed resistance mechanisms to the latter stress factors. therefore, a split plot rcbd field experiment was conducted with three replications to explain interrelations of leaf chlorophyll, proline and soluble carbohydrates content and grain yield of six linseed genotypes under t...

Vegetation monitoring is one of the essential applications of remote sensing. Regarding agricultural lands, a primary goal is crop state assessment throughout the growing season. Remote sensing techniques make use of multispectral data to estimate plant biophysical and biochemical characteristics by implementing quantitative relationships between crop growth variables and spectral properties. C...
