The Behaviour for SRC Willow Inger in Experimental Trial Ghilad, Romania

Abstract

The use of bioenergy are increasing in many European countries and an important role will be played by biomass produced in willow SRC. Short Rotation Coppice (SRC) willow was developed in Sweden in 1970 and it is cultivated for the production of wood chips. In Romania there are not more than 800 hectares, half of them are in Banat area. In this context assessing the biomass yield in the different experimental trial are very important. Research have been made in three SRC willow experimental trials established in Ghilad, Timis County, Romania. The material consist in willow Inger. All three trails have been established in the year 2011 but harvested in different years. Measurements and observation were made on 15 plants at the end of the 2014 season. One plant from each experimental trial has been harvested and then weight in order to establish their aboveground and underground biomass. Research highlight significant differences according with a number of shoots per stump and shoot diameter according with harvested year. According with stump age and the number of harvests, significant differences were established for quantitative character diameter. There also have been put in evidence the differences between the aboveground and underground biomass for different willow age. This screening about biometric characteristic and aboveground biomass showed high value for willow SRC harvested every year. We have to notice that any economic aspect have not been evaluated

Adaptive potential and productivity of two Salix viminalis L. clonal varieties grown in North Central Bulgaria

“…commercial willow varieties investigated in an experiment in south-western Slovakia. The increase in shoot number at the subsequent rotations found in our study is in line with the observations on willow re-sprouting by Tsanov (1965aTsanov ( , 1974a, Demo et al (2013), Hernea et al (2015), Miller (2018. In agreement with our results, Miller (2018) registered a shoot number increase by 50 to 100% after coppicing, while Tsanov (1965a) recorded tripling of Salix viminalis sprout number and a four-fold increase for Salix rubra.…”

“…The genus Salix comprises 330-500 species, appearing in several life forms: upright trees, shrubs, prostrate plants or groundcovers, with the majority of taxa occurring as shrubs (Dickmann & Kuzovkina, 2014). Willows have shown to possess numerous advantages for cultivation such as fast growth, remarkable capacity of vegetative regeneration, very high sprouting capacity, high productivity, short rotation cycle, broad genetic base, low economic investments after establishment (Hernea et al, 2015). The species of willow (Salix spp.)…”

Productivity of Short-Rotation Poplar Crops: A Case Study in the NE of Romania

“…The hybrid poplar cover grew in Romania, reaching more than 73,000 ha, with approximately 2600 hectares of biomass short-rotation crops [40]. By comparison, hybrid willow crops cover only 800 hectares [46]. Romania has great potential in Eastern Europe for developing SRWCs.…”

Evaluation of the Behavior of Some Genotypes of Salix sp. in the Conditions of Sandy Soils

“…volume weight and mechanical solidity. These parameters depend on used material, its structure, water content and compacting pressure (Weger et al, 2016) In Romania, willow short rotation coppice has been developed from 2005, exclusively on agricultural, non-forest land, about 800 ha of willow and Inger is the most cultivated commercial Swedish clone in Romania (Hernea et al, 2015), but a few experimental trials clone have been made in order to test the capacity of willow clones to adapt in different sites condition.…”
