Abstract

Virginia mallow (Sida hermephrodita Rushby), Malvaceae family, is a perspective perennial herb able to yield a biomass crop through the last two decades. In our previous studies, we examined two factors relating to seed germination percent and seed germination power during our research: the influence of hot water treatment and the effect of exogenous or endogenous infection of seed. Following these recognition we modifi ed our technique, in such a way that we fractionated the seeds based on their fresh weight / or relative density before we carried out the treatment. When we fi ltered the fl oating seeds on the surface of water, the hot water treatment was performed considerably better on the sink seeds after separation. Therefore, by this special priming process we were able to reach 80% germination capacity of Virgina mallow seeds under laboratory conditions (26 oC without illumination). From all nurseries tray methods preliminary results, it is clear that, Sida seeds, which were treated with these methods, gave the best growing rate for industrial uses.

Highlights

The European Commission presented an action plan to reduce the insecurity of investors by evaluating the physical and economic availability of different biomass types, including wood and wood residues, waste and agricultural crops, and by determining priorities regarding the biomass types in use and ways of developing them, as well as by pointing out measures to be taken in order to enhance this
From 2003 we have studied our Sida germplasm collection at Future Biomass Plants Garden of the Centre of Agriculture, University of Debrecen (Debrecen, Hungary)
Seed pretreatment by Floated Seed Priming Technique (FSPT). It could be found detailed information about Hot Water pre-treatment Method (HWT) and its influence on germination and contamination rate in our previous study (Kurucz et al, 2013). This HWT protocol was complemented with a simple seed priming step to fractionate them based on their specific weight, and or imbibition / permeability characteristic

Summary

Introduction

The European Commission presented an action plan to reduce the insecurity of investors by evaluating the physical and economic availability of different biomass types, including wood and wood residues, waste and agricultural crops, and by determining priorities regarding the biomass types in use and ways of developing them, as well as by pointing out measures to be taken in order to enhance this. This action plan is connected with consumer information campaigns about the benefits of biomass and bioenergy (Pszczółkowska et al, 2012). It is well documented that, biomass is a renewable resource and refers to any material having recent biological origin, such as plant materials, agricultural crops, and even animal manure. Biomass can be defined as any plant-derived organic matter (Kaur et al, 2014). Biomass available for energy on a sustainable basis includes herbaceous and woody energy crops, agricultural food and feed crops, agricultural crop wastes and residues, wood wastes and residues, aquatic plants, and other waste materials including some municipal wastes. Biomass is a very heterogeneous and chemically complex renewable resource. Owing to its natural abundance, sustainability, and often low cost, biomass is a potential alternative to nonrenewable energy sources for production of chemicals (Kaur et al, 2014)
