Knowledge regarding the origin and maintenance of hybrid zones is critical for understanding the evolutionary outcomes of natural hybridization. To evaluate the contribution of historical contact vs. long-distance gene flow in the formation of a broad hybrid zone in central and northern Georgia that involves Aesculus pavia, A. sylvatica, and A. flava, three cpDNA regions (matK, trnD-trnT, and t...

Plants produce several chemically diverse bioactive substances that may influence the growth and development of other organisms when released into environment in a phenomenon called allelopathy. Several these allelopathic species also have reported medicinal properties. In this study, potential effects more than hundred plants from Cambodia were tested using dish pack method. The bioassay metho...

Abstract The species diversity and safety of a 70-year-old collection tree shrub introduced in the arboretum Dzhanybek Research Station, located rainfed conditions semi-desert Northern Caspian region, was studied. created on hydromorphic meadow-chestnut soils mesodepression relief 1953. At present stage, 75 belonging to 23 families 43 genera have been identified arboretum. It analyzed that most...

Ecological aspects of abandoned lands can be determine from many aspects, including the family diversity and ability to absorb water. This study aims important value index based on tree water (infiltration rate permeability) land after traditional gardens. The vegetation survey trees with a diameter at breast height (DBH) >5 cm was carried out 10 sub-plots each measuring 20 m × m. Infiltrati...
