“…1). The P-phytoremediation capacity of willow has been already reported [46][47][48], and therefore, was not the focus of our study. However, we demonstrated here that the higher P concentration found in PO 4 3-fertilized plants may have a role in the plant's physiological responses to glyphosate.…”

HighlightsPhosphate increased glyphosate uptake and decreased its toxicity in willows PO 4 3-concentrations ≥ 200 mg l -1 doubled glyphosate uptake by willow roots PO 4 3-concentrations ≥ 200 mg l -1 increased antioxidant system activity PO 4 3-maintained photosynthesis rates by inducing reactive oxygen species scavenging 3 Abstract Phosphate (PO 4 3-) has been shown to increase glyphosate uptake by willow, a plant species known for its phytoremediation potential. However, it remains unclear if this stimulation of glyphosate uptake can result in an elevated glyphosate toxicity to plants (which could prevent the use of willows in glyphosate-remediation programs). Consequently, we studied the effects of PO 4 3-on glyphosate uptake and toxicity in a fast growing willow cultivar (Salix miyabeana SX64). Plants were grown in hydroponic solution with a combination of glyphosate (0, 0.001, 0.065 and 1 mg l -1 ) and PO 4 3-(0, 200 and 400 mg l -1 ). We demonstrated that PO 4 3-fertilization greatly increased glyphosate uptake by roots and its translocation to leaves, which resulted in increased shikimate concentration in leaves. In addition to its deleterious effects in photosynthesis, glyphosate induced oxidative stress through hydrogen peroxide accumulation.Although it has increased glyphosate accumulation, PO 4 3-fertilization attenuated the herbicide's deleterious effects by increasing the activity of antioxidant systems and alleviating glyphosateinduced oxidative stress. Our results indicate that in addition to the glyphosate uptake, PO 4 3-is involved in glyphosate toxicity in willow by preventing glyphosate induced oxidative stress.

“…50% of willow cultivations are fertilized with municipal sewage, and on the remaining cultivations, mineral fertilization with a dose of ca. 100 kg·ha -1 N is used, while in Canada, an equivalent of fertilization of 100-150 kg·ha -1 N is recommended taking into consideration organic fertilization [17]. Willow absorbs the largest quantities of nitrogen in the period from April to October, and does it most intensely from May to July [18].…”

The purpose of the present paper was an assessment of the successive impact of fertilization with nitrogen on the regrowth dynamics of the shoots of 10 genotypes (three clones and seven varieties) of basket willow (Salix viminalis L.) in the 9th and 10th year of cultivation. In 2008- 2015, mineral nitrogen fertilization was applied in the whole experiment in four doses. The measurements of height and thickness of willow shoots, of the quantity of live and dead shoots in the snag and live and dead snags on the plot were performed in the experiment realized in 2016-2017. Biometric measurements showed that increased mineral nitrogen fertilization in the year of its application intensified shoots growth in height and thickness, yet in the successive impact, in the 9th and 10th year of willow vegetation weakening of shoot regrowth in height and thickness is observed, and the number of live shoots in the snag and live snags on the plot have reduced. In particular, negative successive impact of the nitrogen fertilization on the willow canopy architecture was demonstrated on the objects that were mowed twice in the first 4-year rotation and on the varieties that do not tolerate this treatment.

“…The caloric value of bark is less favorable than that of wood and bark produces a higher amount of ash (Klasnja et al 2002;Feng et al 2013). The latter is related to the inorganic substances (Fengel and Wegener 1983), which can cause damage to wood boilers via corrosion or blockage of the burner gate (Feng et al 2013;Guidi et al 2013). Moreover, the particulate matter and NOx emissions produced by the combustion of bark is higher than with wood.…”

Short-rotation coppices have potential to be the future source of raw materials for many applications in the wood and paper industries. It is important to establish methods and products to handle their waste biomass. In this paper, the properties of bast fibers extracted from the bark of willow trees (Salix spp.) were evaluated for potential future use in the production of natural fiber-polymer composites. The anatomy of the fibers was investigated through optical and electron microscopy. The thermogravimetric analysis of these fibers showed that the major mass loss occurs at 257 °C. The density of the fibers was measured with a gas pycnometer (1.19 ± 0.2 g/cm 3 ). The chemical analysis showed that willow bark fibers have a composition similar to willow wood. As an indicator of mechanical properties, single willow bast fibers were characterized by tensile tests. The results revealed values for tensile strength (307.6 ± 130.1 MPa) and Young's modulus (16.9 ± 8.4 GPa) that are comparable to some commonly used natural fibers. The overall results showed that willow bast fibers have the required mechanical properties as well as thermal stability for application in reinforcement of polymers.
