Hydraulic conductance exerts a strong influence on many aspects of plant physiology, namely: transpiration, CO2 assimilation, growth, productivity or stress response. However we lack full understanding of the contribution of root or shoot water transport capacity to the total water balance, something which is difficult to study in trees. Here we tested the hypothesis that whole plant hydraulic ...

The effect of four water salinity levels (0.75, 5, 10 and 15 dS.m -1 ) on growth indices and physiological parameters in some wild pistachio (P. atlantica, P. atlantica subsp. kurdica, P. atlantica subsp. mutica and P. atlantica subsp. cabulica) were investigated under greenhouse conditions. Leaf dry weight was reduced to about 30-54% at ECw 10 dS.m -1 . Chemical analysis of shoot and root indi...

in order to investigate the effects of salicylic acid on some growth and stomatal characteristics of calendula plant, a factorial experiment was conducted based on completely randomized design with five replications in the research greenhouse of shahid bahonar university of kerman in 2013. salt stress levels including 1, 3, 5, 7 and 9 mmhos/cm were applied to the soil and salicylic acid solutio...

This study describes the variation in the mean relative shoot Ca content within the angiosperms at the ordinal level. Data were derived from studies in the literature in which the shoot Ca content of two or more species had been compared, and from a hydroponic experiment in which plants were selected to represent the relative number of species within each angiosperm order. Across all angiosperm...

Turfgrass nutrient uptake may be differentially affected by different salts. The objective of this study was to compare nutrient uptake in tall fescue (Festuca arundinacea Schreb.) as affected by carbonate, chloride, and sulfate under iso-osmotic, iso-Na+ strength conditions. 'Tar Heel II' and 'Wolfpack' cultivars were subjected to NaCl, Na2CO3, Na2SO4, CaCl2, NaCl+ CaCl2, Na2CO3+ CaCl2, and Na...

A greenhouse experiment was performed to investigate growth and physiological responses to water depth in completely submerged condition of a wetland plant Carex schmidtii Meinsh., one of the dominant species in the Longwan Crater Lake wetlands (China). Growth and physiological responses of C. schmidtii were investigated by growing under control (non-submerged) and three submerged conditions (5...

A factorial completely randomized block design experiment with three replications was carried out in greenhouse to evaluate cereal genotypic variation in phosphorus (P) acquisition and utilization efficiency in a calcareous soil with low available P (4.6 mg P kg-1 soil) and high total P (1260 mg P kg-1 soil). Treatments consisted of eight bread wheat (Triticum aestivum L.), three durum wheat (T...
