application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. therefore, scientists are searching for alternatives to antibiotics nowadays. medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. in this paper, the benefits of...

Total number of pollen, pollen recognition, fructose, glucose, sucrose and moisture were examined in 41 honey samples collected Ayder Plateau August 2012. Following the recognition samples, 36 taxa detected. Castanea sativa Miller. was found all a dominant. The total (TPN-10 g) 10g varieted between 3438 87056. It has been determined that normal dominant pollen. content ranged 16.4-20.9%. In fru...

Review article] Botanists have likened the impact of Phytophthora cinnamomi in Australian plant communities to that of the last ice age, which affected a large number of plant families, genera and species within these families. Phytophthora cinnamomi affects the floristics and structure of many unique plant communities. We discuss the impact of this pathogen and our current knowledge of its bio...

In this study, pollen grains were sampled by using a Lanzoni trap (Lanzoni VPPS 2000) in atmosphere of Bursa in 1999 and 2000. During two years. a total of 13,991 pollen grains/m3 which belonged to 59 taxa and unidentified pollen grains were recorded. A total of 7.768 pollen grains were identified in 1999 and a total of 6.223 in 2000. From these taxa, 36 belong to arboreal and 23 taxa to non-ar...

This paper examines the first year results from a silvicultural study of American, hybrid (BC2F3) and Chinese chestnut seedlings (Castanea spp. Mill.) on the Daniel Boone National Forest in southeastern Kentucky. After one year, no significant differences in growth were found among the silvicultural treatments. Hybrids and Chinese seedlings added significantly more height growth than the Americ...

ABSTRACT A three-generation American chestnut x Chinese chestnut pedigree was used to construct a genetic linkage map for chestnut and to investigate the control of resistance to Endothia parasitica (chestnut blight fungus). DNA genotypes for 241 polymorphic markers (eight isozymes, 17 restriction fragment length polymorphisms [RFLPs], and 216 random amplified polymorphic DNAs [RAPDs]) were ass...
