The aim of this study was to investigate whether the composite photosynthetic bacterial inoculant PS21 alleviate the damage inflicted on wheat seedlings by tetrabromobisphenol A (TBBPA). The biochemical characteristics of wheat seedlings were analysed through laboratory simulation after co-treating seedlings with PS21 and 0, 5, 10, 20, 40, 80 and 100 mg kg-1 TBBPA, respectively. The results sho...

to find the protective role of exogenous nitric oxide (no) on salinity-stressed rice seedlings, a crd-based factorial experiment with three replications was conducted in agronomy laboratory of the faculty of agricultural sciences, university of guilan, in 2012. the experimental design consisted of healthy and vigorous seedlings of two rice cultivars, khazar and goohar, the last already known as...

Salt-soluble protein extraction, important in forming meat emulsions, is dependent on several factors including species of the protein source. The purpose of this experiment was to quantify the amount of salt-soluble proteins in various muscles of three species commonly used in meat products beef, pork, and chicken. Pork and beef serratus ventralis muscles (dark) and the semitendinosus muscles ...

this research was conducted at the agricultural college of tehran university in 2005 to analyze the effect of use of cytokinin as well as of calcium on durability of rose (illona cultivar). cuttings were taken from rose biennial mother plants, then treated by cytokinin of 0, 0.1, 1and10 micromole per liter and calcium of 0,10,20 and 30 milimole per liter. cut flowers, after harvest, were kept i...

The essential oil of Rosa damascena Mill. is one of the most valuable and important base material in the flavor and fragrance industry. It has also some medicinal properties. The aim of this study was to determine the correlation between anthocyanin and essential oil content of Damask rose petals in 6 important Damask rose growing in some locations of Iran i.e. Meimand, Layzangan, Shiraz Eram B...

Salicylic acid (SA) is a naturally occurring plant hormone that has positive effects on growth and tolerance to biotic and abiotic stresses, especially salinity in plants. To evaluate the effects of SA and salt stress on some morphological and physiological traits and quantitative activities of antioxidant enzymes on thyme (Thymus vulgaris), was conducted a factorial pot experiment based on com...

the influence of water deprivation on potted grape (vitis vinifera l.) was investigated. leaf mass area (lma) and biochemical responses, including chlorophyll, total protein, peroxidase activity, soluble carbohydrates, photosynthesis and stomatal conductance were assessed in leaves of ‘sahani’ and ‘bidane sefid’ grape cultivars subjected to progressive drought (soil water potentials of: -0.2, -...
