TL;DR: Willows have been shown to be promising for Cd phytoextraction, and the intensity of visible phytotoxicity symptoms on the leaves increased from 3 to 50M and then decreased at higher concentrations, whereas at 100M, S. viminalis exhibited strong stress symptoms, whereas 200M impaired survival.

TL;DR: Irrespective of glyphosate applications, concentrations of shoot macro- and micronutrients were found lower in the near-isogenic GR-cultivars compared to their respective non-GR parental lines.
Abstract: Although glyphosate-resistant (GR) technology is used in most countries producing soybeans (Glycine max L.), there are no particular fertilize recommendations for use of this technology, and not much has been reported on the influence of glyphosate on GR soybean nutrient status. An evaluation of different cultivar maturity groups on different soil types, revealed a significant decrease in macro and micronutrients in leaf tissues, and in photosynthetic parameters (chlorophyll, photosynthetic rate, transpiration and stomatal conductance) with glyphosate use (single or sequential application). Irrespective of glyphosate applications, concentrations of shoot macro- and micronutrients were found lower in the near-isogenic GR-cultivars compared to their respective non-GR parental lines Shoot and root dry biomass were reduced by glyphosate with all GR cultivars evaluated in both soils. The lower biomass in GR soybeans compared to their isogenic normal lines probably represents additive effects from the decreased photosynthetic parameters as well as lower availability of nutrients in tissues of the glyphosate treated plants.

TL;DR: A linear relationship was found between E and g(plant) for the stomatal control of transpiration and the significance of temperature for tree water transport.
Abstract: The effects of temperature on root and shoot hydraulic conductances (g(shoot) and g(root)) were investigated for Quercus robur L. saplings. In a first experiment, conductances were measured with a High Pressure Flow Meter on excised shoots and detopped root systems. The g(root) and g(shoot) increased considerably with temperature from 0-50 degrees C. Between 15 degrees C and 35 degrees C, g(shoot) and g(root) varied with water viscosity. In a second experiment, the impact of temperature-induced changes in g(root) on sapling transpiration (E) and leaf water potential (psileaf) was assessed. Intact plants were placed in a growth cabinet with constant air and variable soil temperatures. E increased linearly with soil temperature but psileaf remained constant. As a consequence, a linear relationship was found between E and g(plant). The results illustrate the significance of g(plant) for the stomatal control of transpiration and the significance of temperature for tree water transport.

TL;DR: In this paper, Halopyrum mucronatum (L.) Stapf was grown in 0, 90,180, and 360 mol m−3 NaCl in a sand culture using a sub-irrigation method.
Abstract: Halopyrum mucronatum (L.) Stapf. is a perennial grass found on the coastal dunes of Karachi, Pakistan. Halopyrum mucronatum plants were grown in 0, 90,180, and 360 mol m‐3 NaCl in a sand culture using a sub‐irrigation method. Fresh and dry weight of roots and shoots peaked at 90 mol m‐3 NaCl. A further increase in salinity inhibited plant growth, ultimately resulting in plant death at 360 mol m‐3 NaCl. The relative growth rate of plants was highest between 60 and 90 days after final salinity concentrations were reached. Maximum succulence was noted in 90 mol m‐3 NaCl. Water potential and osmotic potential of plants became more negative with an increase in salinity, while plants lost turgor with increasing salinity. Time of harvest did not have any significant effect on the water relations of plants. Sodium (Na) and chloride (Cl) content of plants increased with an increase in salinity, while calcium (Ca), magnesium (Mg), and potassium (K) content decreased. Glycinebetaine content of shoots increa...

TL;DR: This work examined the effect of a PVS2 cryoprotection protocol on the water content and phase behavior of mint and garlic shoot tips using differential scanning calorimetry and quantified the extent that ethylene glycol and dimethyl sulfoxide components permeate into shoot tips and replace some of the water.
