in this research, the bud and cane winter cold tolerance of 22 field-grown grapevine cultivars of kourdestan province agricultural and natural resources research and education center was evaluated at jan. and mar. stages in 2012. in these cultivars soluble carbohydrates and water content changes of buds and canes during dormant period also were measured. after exposure to different freezing tem...

Seasonal dynamics of total non-structural carbohydrates (TNC) in relation to the leaf-fruit ratio were measured over five years at different grapevine phenological stages in oneand two-year-old canes, trunks and roots of the cultivar 'Chasselas' (Vitis vinifera L.). Carbohydrates were mainly stored as starch in different parts of the grapevine during the growing season. Soluble carbohydrates re...

this experiment was conducted to study the effect of plastic mulch on the growth and some physiological characteristics of two strawberry cultivars (paros and queen elisa) under drought stress. a factorial experiment was performed based on randomized complete block design with four treatments, including mulch, without mulch, normal irrigation (control) and deficit irrigation (-10 bar) with thre...

To gain a better understanding of molecular and biochemical events involved in light intensity adaptations of Dunaliella salina, we studied the expression of phytoen synthase (psy) gene; pigments, carbohydrates, proteins and lipids accumulation under two light intensities. The cells were pre-cultured under 50 µmol photon m-2s-1 light intensity and then transferred to two different light intensi...

Betaglycan is an accessory receptor of members of the transforming growth factor-beta (TGF-beta) superfamily, which regulates their actions through ligand-dependent interactions with type II receptors. A natural soluble form of betaglycan is found in serum and extracellular matrices. Soluble betaglycan, prepared as a recombinant protein using the baculoviral expression system, inhibits the acti...

Plants are necessarily highly competitive and have finely tuned mechanisms to adjust growth and development in accordance with opportunities and limitations in their environment. Sugars from photosynthesis form an integral part of this growth control process, acting as both an energy source and as signaling molecules in areas targeted for growth. The plant hormone auxin similarly functions as a...
