“…Different from annual average 18-20% set in biomasses of cocksfoot, switchgrass and ryegrass, 14-17% -tall fescue and reed canary grass, and the smallest different were set of lucerne -9%. These data corroborate the findings of other researchers: Pocienė and Kadžiulienė (2016) have reported that reed canary grass and tall fescue produced 106-122 GJ ha -1 .…”

The aim of the study was to evaluate six perennial grass species: lucerne (Medicago sativa L.), reed canary grass (Phalaris arundinacea L.), tall fescue (Festuca arundinacea Schreb.), cocksfoot (Dactylis glomerata L.), switchgrass (Panicum virgatum L.) and ryegrass (Lolium perenne L.), with a balanced composition of organic compounds and minerals, for their suitability for direct combustion in relation to grass species, chemical composition and growth stage. At the regrowth and heading / inflorescence emergence stages, the chemical composition of the biomass of the tested grass species was similar. Before regrowth in spring, the plants contained higher concentrations of carbon, lignin and cellulose and the smallest amounts of ash and nitrogen. Of all the grass species tested, the biomass of lucerne, tall fescue and particularly ryegrass was the most suitable for direct combustion, as it had the highest concentration of carbon (57.55%) and the lowest concentration of nitrogen (0.61%) and ash (4.48%). The findings suggested that the heating value of the biomass was determined by plant growth stage and chemical composition. It was the highest at the heading stage and before regrowth in spring. It was found that the biomass of lucerne produced the highest energy yield of 303 GJ ha-1 (a sum of two harvests). The biomass of tall fescue produced 185.2 GJ ha-1 , and that of cocksfoot-137.3 GJ ha-1. The biomass of reed canary grass produced a lower energy yield of 93.3 GJ ha-1. The analysis of the relationship between the heating value and chemical composition of the biomass showed a strong correlation between the heating value and acid detergent lignin (ADL) 0.548** (p < 0.01). The heating value was also found to positively correlate (p < 0.05) with cellulose (0.376*) and carbon (0.258*).

“…There are three major categories of perennial crops grown for biomass. These are short rotation woody crops (SRWCs) such as willow, poplar, eucalyptus, black locust; herbaceous crops such as Virginia mallow, willow-leaf sunflower, cup plant; grasses such as giant miscanthus, prairie cordgrass, switchgrass and giant reed [9][10][11]. Although such a large diversity of perennial crops offers the advantage of providing farmers with many choices, one has to possess sufficient knowledge in this regard.…”

Perennial crops harvested in short rotations provide substantial amounts of biomass. This study determined the survival rate, biometric features and yield of fresh and dry biomass of 15 willow genotypes (including seven varieties and eight clones), cultivated at two different sites in two consecutive three-year harvest rotations. The study revealed the very high impact of the genotype (81% of the total variance) on the willow yield. The harvest rotation, along with the genotype, had a significant impact on the plant survival rate and the number of shoots per stool. Willow biomass was mainly affected by the plant height, its survival rate and shoot diameter. The significantly highest fresh (106 Mg ha−1) and dry biomass yield (54.0 Mg ha−1) was obtained from the Żubr variety of S. viminalis, which distinguished this variety from the other genotypes. The mean yield for the best three and five genotypes was 13% and 17% lower, respectively, and the mean yield for the whole experiment was 37% lower compared to the mean yield of the best variety (Żubr). Therefore, the choice of a willow genotype is of key importance for successful willow production.

During the 1950s-1960s, the Merkys river basin, the largest protected area of Lithuania, underwent severe anthropogenic regulations. Within the Baltic States, the genetic diversity of Phalaris arundinacea populations is unknown and how they might be affected by anthropogenic activities such as river regulation. The objectives of this study were to compare molecular parameters (SSRs or microsatellite loci) within and among populations from natural river fragments with populations from regulated river parts. Study populations have greater genetic diversity within, rather than among, populations. The upstream portion of the Merkys basin populations had lower genetic diversity compared with further downstream. The mean number of polymorphic SSR loci was lower for populations from regulated parts of the river basin compared with natural ones. Main principle coordinate analysis revealed populations of regulated rivers at marginal positions. Bayesian clustering showed that current populations are admixtures of 3 distinct genetic groups, based on STRUCTURE analysis (K = 3 groupings) in geographic subdivisions of (a) downstream populations (Varėnė, Verseka, Upper Grūda, Lower Grūda, Upper Merkys, Lower Merkys), (b) upstream populations (Upper Šalčia, Beržė, Lower Šalčia, Visinčia, Lower Šaltykščia, Nedilė), and (c) the 2 regulated sites in the distinct geographic area of Taurupis and Upper Šaltykščia.P. arundinacea in the Merkys river basin does not all belong to a single, random-mating population encompassing its tributaries or among populations across its geographic scales. In several instances, river regulation might impair the genetic diversity of P. arundinacea populations.
