ABSTRACT: Wood plastic composites (WPCs) were produced from different mixtures (up to 45% by weight) of poplar (Populus alba L.) and pruning branches of black locust (Robinia pseudoacacia) species wood flours, polypropylene (53 wt%), and maleic anhydride-grafted polypropylene (MAPP, 2 wt%). Weight loss (WL), flexural strength (MOR), flexural modulus (MOE), notched impact strength (IS), water absorption (WA), and thickness swelling (TS) of WPCs after 24 h immersion in distilled water were determined before and after incubation with white-rot fungus (Trametes versicolor) for 7 weeks. The MOR and MOE increased with an increase of poplar wood in the WPC. The notched IS decreased with an increase of black locust wood and poplar wood in the WPC. The weight loss of WPCs exposed to white-rot fungus was minimal for the WPCs with a high amount of black locust pruning branches flour. The MOR and MOE declined after the incubation with fungus. Fungal decay had a significant influence on the notched IS. Furthermore, the results indicated that the WA and TS of white-rotted WPCs for all the WPC formulations were significantly higher than those of un-rotted WPCs.

ABSTRACT: Grasses (Poaceae) are among the most important and widely cultivated plants. Identification of grass species using morphological characters is a difficult task for nonspecialists, and it is not always an accurate method. DNA-based molecular markers have been widely used as an alternative towards more accurate identification of plant species. The molecular method that can be effective for large-scale identification of grass species, however, must satisfy requirements for specific amplification of DNA and reveal enough variability to distinguish species. The goal of this study was to evaluate the ability of pyrosequencing to detect SNP polymorphisms for an optimal discrimination of grass species. PCR amplifications and the sequencing of 19 fragments of chloroplast genes were performed using a pooled DNA template of 32 British native grass species to be identified and chloroplast DNA-specific universal primers. Based on amplicon size and sequence variance, the 6 most variable loci (psbE&F, rbcL.1, ndhF.1, ndhF.2, ndhF.3, and clpP&rps12) were selected to be targeted for pyrosequencing of the species analyzed. The pyrosequenced regions contained sufficient polymorphisms to allow the complete diagnosis of all species analyzed, except for Elymus caninus and Elytrigia repens, which had identical sequences unique from the remaining species. When targeted loci were pyrosequenced in representative species of the 2 economically important grass genera Festuca L. (8 species) and Poa L. (11 species), all species in each genus could be separated. Should the SNP markers developed here proved to be species-specific, they can provide a valuable tool for reliable diagnosis of grasses and applications (e.g., forensic botany) moving forward.
