Poplar belongs to the family Salicaeceae, order Salicales and group Amentiflorae (Dickmann and Stuart, 1983; Eckenwalder, 1996). There are 35 species of poplar currently recognized in the world; out of those, 6 Populus species are indigenous to India– P. alba, P. ciliata, P. euphratica, P. gamblei, P. glauca and P. laurifolia, and during past many clones of exotic species of poplar (P. deltoide...

In flat sedimentary plains in areas with a sub-humid climate, tree planting on grasslands and arable lands creates strong hydrological shifts. As a result of deep rooting and high water uptake of trees, groundwater levels drop and subsurface salt accumulation increases. Tree planting has expanded globally and in Hungary it reached rates of 15 000 ha year(-1), being focused mainly in the Great H...

Poplar-cotton agro-ecosystems are the main agricultural planting modes of cotton fields in China. With increasing acres devoted to transgenic insect-resistant poplar and transgenic insect-resistant cotton, studies examining the effects of transgenic plants on target and non-target insects become increasingly important. We systematically surveyed populations of both target pests and non-target i...

small diameter timbers have many used in wood and paper industries such as veneer and plywood, furniture industry, wood working and their particle for papermaking and particleboard. diameter of small diameter poplar is between 15 to 35 cm and poplar trees are planted in excess of 23 provinces of iran. small diameter poplar are visual graded to lumber of sawmill. since, small diameter poplars ar...

Poplar is not only an important resource for the production of paper, timber and other wood-based products, but it has also emerged as an ideal model system for studying woody plants. To better understand the biological processes underlying various traits in poplar, e.g., wood development, a comprehensive functional gene interaction network is highly needed. Here, we constructed a genome-wide f...

Important losses in poplar productivity occur because of susceptibility to microbial pathogens. To enhance disease resistance in susceptible genotypes, the gene coding for D4E1, a synthetic antimicrobial peptide consisting of 17 amino acid residues, was introduced into poplar (Populus tremula L. x Populus alba L.) via Agrobacterium-mediated transformation. Four kanamycin-resistant transformants...

Intercropping perennial legumes with trees can reduce Nitrogen (N) losses, due to the high amount of N accumulated in stable forms soil and permanent cover during whole year. Although cycling improvement mature agroforestry systems (AFS) was well documented, there is a lack knowledge regarding transition AF. In this work, we studied association two forage crops, namely ryegrass (Lolium multiflo...
