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, -...

To explore the function of light-harvesting complex protein (LHCP) in Arabidopsis growth and development, the Leclere and Bartel seed collection was screened. In this collection randomly cloned cDNAs are expressed under the CaMV35S promoter. A pale green line has been identified and characterized in more details. Analysis of the inserted cDNA in the pale green line showed it encodes LHCB1 prote...

in this research, the effect of water stress on the soluble sugars, starch and proteins content of two different cultivars (kaka and jam) of chickpea (cicer arietinum) was studied. the results showed that the soluble sugars increased while starch decreased during the stress in shoot and root of both cultivars. increasing of soluble sugars and decreasing of starch hall a positive correlation wit...

Abstract Background As a biennial plant, Secale cereale L is usually harvested in the autumn northern part of China where temperature difference between day and night great disparity Through pot experiment, seedlings were cut to 2, 6 10 cm stubble height, simulated freeze-thaw (FT) stress (10/− 5 °C) was carried out after days regrowth. The physiological effects FT with different height reveale...

drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. to evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. cultivars with two-level white seedless and khosh...

frost in early spring is one of the limiting factors in the production of grape. chemicals offer useful approach to reduce low temperature-induced damages. different concentrations of salicylic acid including: 0 (control), 0.5, 1 and 2 mm were sprayed twice on 10 year-old ‘bidaneh sefid’ grape vines at full bloom stage and changes in leaf soluble carbohydrates, proline and protein levels were m...
