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...

Selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. The present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. For this purpose an experiment was c...

in order to study the effect of different water potential on anethum graveolens l. an experiment was conducted. this study was carried out based on completely randomized design with three replications. in this experiment, morpho-physiological characteristics were assessed under hydroponic. stress was established with peg 6000, and drought potentials were: 0 (control), -1.5, -2, -2.5 and -3 bar....

The in-chlorophyll centre waveband (ICCW) (640-680 nm) is the specific chlorophyll (Chl) absorption band, but the reflectance in this band has not been used as an optimal index for non-destructive determination of plant Chl content in recent decades. This study develops a new spectral index based solely on the ICCW for robust retrieval of leaf Chl content for the first time. A glasshouse experi...

this study investigated the relationships between nutrients and chlorophyll, a concentration in the international alma gol wetland. chlorophyll a is the major photosynthetic pigment in lots of phytoplanktons and has been used as a trophy index in aquatic ecosystems. water samples were collected fortnightly from five stations in the wetland during summer and autumn. chlorophyll-a ranged between ...

This study was conducted to assay the effects of methanol foliar application (0, 10, 20 and 30% v/v) and bed cover (control, white and black covers) on yield and some physiological traits of marigold as a factorial based on RCBD. The results revealed the significant interaction effects of bed cover and methanol foliar application on chlorophyll a content and plant height. The highest plant heig...

water deficit, ultraviolet radiation and carbon dioxide enrichment are the most important environmental factors in global climate change. this research was conducted in tarbiat modares university, research greenhouse and the objective of that was to study the effects of three levels of carbon dioxide (500, 900 and 1300 ppm), uv-radiation (uv-a, b and c with intensity of 18, 25 and 40 µw.cm2 res...
