Seedling test and genetic analysis of white poplar hybrid clones

Forestry Studies in China, 2008
Cross breeding strategies are very efficient for gaining new and superior genotypes. Ninety-eight new white poplar hybrid clones produced from 12 cross combinations within the Section Leuce Duby were studied using genetic analysis and seedling tests.

Foliar Response of Six Clones of Hybrid Poplar

Phytopathology, 1978
After exposure to simulated acid rain at pH levels from 2.7 to 3.4, lesions of several types were produced on foliage of six clones of Populus spp. hybrids. The types of adaxial leaf surface lesions were observed at low magnification by scanning electron microscopy, and via leaf histology. On two clones, galls resulting from hyperplasia and hypertrophy

Distribution of Recent Photosynthates in Saplings of Two Hybrid Poplar Clones

Communications in Soil Science and Plant Analysis, 2010
The distribution of recent photosynthates in 1-, 2-, 3-, and 4-year-old saplings of two hybrid poplar clones (Populus balsamifera × deltoides ‘Northwest’ and P. deltoides × petrowskyana ‘Walker’) was studied using the carbon dioxide (13CO2) pulse-labeling technique in summer 2005.

Stomatal control of water use efficiency in poplar clones and hybrids

Canadian Journal of Botany, 1984
Water use efficiency (WUE, the ratio of dry matter produced to water used in transpiration) was studied in 17 poplar clones and hybrids. Although WUE could not be predicted from the poplar group alone, water efficiency was found to vary in different poplar genotypes.

Phytoextraction and Accumulation of Boron and Selenium by Poplar (Populus) Hybrid Clones

International Journal of Phytoremediation, 1999
ABSTRACT There has been much interest recently in central California for reusing drainage water to grow trees. A sand-culture study was conducted to investigate the accumulation of boron (B) and selenium (Se) in eight hybrid poplar (Populus) clones irrigated with synthetic agricultural effluent containing increasing levels of chloride salt, B, and Se ...

Selection for Both Growth and Wood Properties in Hybrid Poplar Clones

Forest Science, 2003
Abstract To better understand the genetic control of growth and wood properties in hybrid poplar (Populus spp.), genetic relationships of selected wood properties with growth traits were examined in a 3-yr-old clonal trial located in Windsor and St-Ours, southern Quebec, Canada.

Energy feedstock characteristics of willow and hybrid poplar clones at harvest age

Biomass and Bioenergy, 2003
Abstract Woody biomass feedstock produced from willow and hybrid poplar can be converted into bioenergy via thermochemical and biochemical processes. Variation in key properties that relate to the quality of biomass feedstock and determine its value for energy conversion were determined at rotation age (3 years), in 30 willow and seven hybrid poplar ...

The effects of flooding on several hybrid poplar clones in Northern China

Agroforestry Systems, 2006
The ecophysiological, morphological, and growth characteristics of 14 poplar clones were studied during 37 days of flooding and a 13-day recovery period. Cuttings were subjected to three soil water regimes, viz. drained (control), shallow flooding to 10 cm above the soil, and deep flooding to a depth of 120 cm.

RESPONSE OF A HYBRID POPLAR CLONE TO SOIL ACIDIFICATION AND LIMING

Canadian Journal of Soil Science, 1985
Unrooted hybrid poplar cuttings were grown in a greenhouse at varying soil pH. The soil was a loamy fine sand (pH 5.7) collected from an Ap horizon of a forest tree nursery. The pH was adjusted over a wide range by incorporating different rates of powdered lime or elemental sulfur.
