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...

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...

Hybrid poplar (Populus spp.) is an important biomass crop being evaluated for cellulosic ethanol production. Predictions of poplar growth, rotation period, and soil carbon sequestration under various growing conditions, soils, and climates are critical for farmers and managers planning to establish short-rotation forestry (SRF) plantations. In this study, we used an ecoinformatics workflow, the...

This study aimed to compare the hydraulic characteristics of different vitalities of Populus euphratica to reveal the differences in their water use strategies and water consumption to provide useful data to scale water use of riparian poplar forests in the lower reaches of the Tarim River, Northwestern China. Our results showed that the sapwood area of P. euphratica could be estimated based on...

The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...

Fourier transform infrared (FTIR) imaging offers the opportunity to analyse the chemical composition of wood spatially resolved. To illustrate the potential of FTIR imaging for wood analysis, the lignin distribution in cross sections of beech and poplar wood was analysed and the spatial resolution compared. Additionally, the ratio of guaiacyl/syringyl lignin in a poplar wood section was compute...

The aim of this work was to study the colonization of indigenous arbuscular mycorrhizal fungi (AMF) species in fine-roots of poplar clones. Roots of 7 poplar clones were sampled from a 1-year-old trial established at an industrial site strongly polluted with heavy metals at Balatonfuzfo, Hungary. The poplar clones have shown variable degrees of colonization by AMF, suggesting differential host ...
