Study On Biodiesel Energy Plant Germplasm Resources In Hebei Province

With the energy crisis and environment problem increasingly prominent,bio-diesel as an alternative to fossil fuels has received worldwide attention recently,and it has broad application prospects. Biodiesel energy plants are renewable andwon’t threaten food security, and they have great development potential. China islimited of arable land, but abundant of plant germplasm resources, therefore, clearingbiodiesel energy plant resources base and selecting good quality species is of greatsignificance for comprehensive development and utilization of biomass energy.Being based on the distribution characteristics of plant resources and literaturematerial consultation, systematically field investigation was carried out for oil plantsin Hebei province. Plant seeds were collected, then oil content and biodiesel qualityrelated indexes of acid value, iodine value, saponification value, fatty acidcomposition were measured. The biodiesel plants having development potential inHebei province were determined by comprehensive analysis. In addition, seedmorphology and introduction of key biodiesel plants were studied, in order toprovided reference for biodiesel plants in classification and cultivation. This studyreached the following conclusions:1.Biological oil energy plants in Hebei province were emphasis investigation,which belonged to74families,191genera and260species, and in which respectivelyaccounted for52.48%of families,23.26%of genera and11.97%of species, amongwhich temperate components had obvious advantages.55oil energy plants ofdevelopment potential were initially identified for further focused research on thebasis of field performance, production and distribution.2.Biodiesel related quality parameters of162kinds of plant seeds weredetermined. The oil contents ranged from0.37%~52.30%, acid value0.88~77.27mg/g, saponification value17.95~576.16mg/g, iodine value6.84~248.16g/100g.The components of oil fatty acid mainly were oleic acid, linoleic acid and linolenicacid, and linolenic acid contents of113kinds of seeds were less than12%, accounting for69.75%. According to biodiesel standards and field investigation,15kinds ofbiodiesel energy plant were tentatively identified in Hebei province, includingPhytolacca Americana L, Magnolia sieboldii K. Koch, Armeniaca sibirica (L.) Lam,P. davidiana (Carr.) Franch, Amygdalus triloba (Lindl.)Ricker, Cerasus humilis (Bge.)Sok, Cerasus tomentosa (Thunb.) Wall, Padus racemosa (Lam.) Gilib, Flueggeasuffruticosa (Pall.) Baill, Rhus typhina L, Euonymus maacki Rupr, Acer mono Maxim,Grewia biloba vra.parviflora (Hand.)Mazz, Elaeagnus multiflora Thunb, Daturastramonium L.3.There were complex diversity in seeds size, single grain weight, externalmorphology, color and surface ornamentation of the biodiesel plants, so thesecharacteristics could be used as the basis of energy plants taxonomy.4.Using the method of seeds, wild living plants and cutting,131kinds of47families biological oil energy plant were introduced. It was showed that key biodieselenergy plant had good performance and strong regional adaptability.
