Evaluation of the Factors that Affect The Lignin Content in The Reed Canarygrass (Phalaris arundinacea L.) in Latvia

Abstract

Abstract:In the production of granules from plants the cohesive substance lignin has a great importance, as it holds the granule together and does not allow it to disintegrate. The objective of this research was to evaluate the influencing factors of lignin content in reed canarygrass (Phalaris arundinacea L.) crop yield. In this research the varieties of reed canarygrass 'Marathon' and 'Bamse' were analysed for yields of first and second year. The lignin content of the samples was established by Classon's method. Arsenic (As), Cadmium (Cd), and Lead (Pb) and other chemical elements were established in the reed canarygrass samples with the spectrometer Optima 2100DV. The reed canarygrass second year crop yield was 3-4 times greater than the first year crop yield. A significantly correlation (p<0.05) was established in the first crop yield October samples between lignin and natrium (Na). Some correlation relationships are contradictory, which confirms that within the plant growth period the meteorological conditions are of great importance. Analysing the determining factors of lignin content it can be seen that they were influenced by the interaction of various factors -the sowing and growing period, the variety and the N-fertilizer rate application.

Italian Ryegrass (Lolium multiflorum Lam.) Fiber Fraction Content and Dry Matter Digestibility Following Biostimulant Application against the Background of Varied Nitrogen Regime

“…What is interesting is the fact that in the first study year lignin amount in plants was the same regardless of the rate of mineral fertilizer. The findings of this study concur with reports by Poisa et al [54] whose work revealed a significant relationship between nitrogen fertilizer level and the amount of lignin in plants.…”

Long‐term manure application for crop yield stability and carbon sequestration in subtropical region

“…Manure application might have improved lignin to cellulose ratio (L-C ratio) in roots and shoots of crops by augmenting N availability (Poisa et al 2011). Interestingly, L-C ratio of roots and shoots of both crops significantly influenced β-glucosidase activity.…”

Influence of Different Factors on Productivity of Reed Growths

“…Traditionally, wood is the most important type of biomass in Latvia [2], however lately it has become common to cultivate different energetic plants and to use them in energy production. One of the most suitable plants for energy extraction and saving is reed canarygrass (Phalaris arundinacea L.) [3,4,5] which is widely studied in the world and is suitable for energy extraction in the conditions of Latvia [6,7,8]. Besides, for energy extraction it is possible to use the biomass of hemp (Cannabis sativa L) [9,10], flax (Linum usitissimum L.) [11,12], different grain and straw [13,14] and other plants.…”
