The moderating role of salicylic acid (SA) and putrescine (PUS) as plant growth regulators (PGRs), on the growth parameters and phytochemical and qualitative characteristics of strawberry fruit 'Selva' under osmotic stress was investigated under soilless culture. The osmotic potential (salinity) of the nutrient solution containing different NaCl concentrations (0, 7.5, 15, 30 and 45 mM) and fol...

Drought is one of the major environmental problems in agricultural field worldwide. The present study investigated the effects of water deficit caused by exogenous application of polyethylene glycol (PEG) on cabbage (Brassica oleracea var. capitata) grown in hydroponic culture. Root length, shoot length, dry weight, and relative water content of the seedlings significantly decreased in dose dep...

in order to study the effect of iron chelate (fe-eddha) on some biochemical characteristic of safflower (carthamus tinctorius l.) under two irrigation regimes, a field experiment was set up a split-plot based on randomized block design with four replication in 2011 in a research field of the faculty of agriculture at shahed university. in this study the main plots consisted of two levels of irr...

The correlation between the peroxidase activity, chlorophyll and soluble protein content as well as the changes in vascular bundle structure in Norway spruce (Picea abies L. Karst.) needles affected by cement dust were studied. In spite of the absence of any yellowing symptoms, a significantly lower chlorophyll con­ tent was measured in spruce needles affected by cement dust. Observed sieve cel...

in order to investigate the responses of sardari wheat ecotypes to drought stress, 12 spikes of sardari wheat were selected from different regions of kurdistan province and planted as head to row. in the second year, a split- plot factorial field experiment was conducted. in this experiment water stress and irrigation were considered as the levels of main factor and 12 sardari wheat ecotypes al...

The estimation of crop chlorophyll content could provide technical support for precision agriculture. Canopy spectral reflectance was simulated for different chlorophyll levels using radiative transfer models. Then with multiperiod measured hyperspectral data and corresponding chlorophyll content, after extracting six wavelet energy coefficients from the responded bands, an evaluation of soybea...

the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. limetta, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} were evaluated on sweet lime leaf chlorophyll content and mineral concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) in a completely randomized design of four replications. budded sweet lime on the above root...

The MERIS Terrestrial Chlorophyll Index (MTCI), a standard level 2 ESA product, provides information on the chlorophyll content of vegetation (amount of chlorophyll per unit area of ground). This is a combination of information on leaf area index (LAI, area of leaves per unit area of ground) and the chlorophyll concentration of those leaves. The MTCI correlates strongly with chlorophyll content...

this study was aimed to study the ways of removing dormancy period and accelerating pre-sowing tuber germination to provide simple tools to apply by farmers. for this purpose, intact tubers, exposed tubers to released ethylene and sliced tubers were examined in respect to germination characters, bud length, starch, anthocyanin and chlorophyll contents and amylase activity. relative amount of an...

The MERIS Terrestrial Chlorophyll Index (MTCI) is designed to monitor vegetation condition via an estimation of chlorophyll content. Its simplicity of calculation, suitability for automation and most importantly, sensitivity to all and notably, high values of chlorophyll content made it a suitable level-2 ESA product. This index effectively combines information on leaf area index and the chloro...
