Molecular and Genetic Approaches to Rust Resistance (Melampsora sp.) in Poplar (Populus sp.)

1996
Various Melampsora rust races are causing defoliations on susceptible cultivars in commercial poplar plantations. Genetic and molecular analyses of parents and families of a factorial mating design have been investigated to determine components of resistance to rust. One genomic area was revealed which was involved in qualitative resistance.

Tolerance of Poplar (Populus sp.) to Environmental Stresses II. Photosynthetic Characteristics of Poplar Clones Grown at Low and High Light Intensities

Journal of Plant Physiology, 1988
Summary Four poplar clones ( Populus sp., Beaupre, Raspalje, Fritzi Pauley and Robusta) were grown at low and high photon flux densities (PFD) and the photosynthetic characteristics of the leaves were examined and compared using photoacoustic and fluorometric techniques. The growth of all the clones (shoot length and leaf area) was markedly reduced

Ozone-induced necrosis and increased peroxidase activity in hybrid poplar (Populus sp.) leaves

Environmental and Experimental Botany, 1986
Abstract Peroxidase activity was assayed in leaves from two positions (nodes 5 and 15) along the stems of four clones of hybrid poplar ( Populus sp.) that had been fumigated with ozone at 0.15 μl/l for up to 6 weeks. Two clones were designated ozone-sensitive, and two were designated ozone-resistant according to the amount of ozone-induced injury ...

Biomass production of hybrid poplar (Populus sp.) grown on deep-trenched municipal biosolids

Ecological Engineering, 2008
Abstract Environmentally sustainable options for recycling municipal biosolids generated from wastewater treatment plants are needed. We measured the wood biomass production of a 50 ha hybrid poplar ( Populus spp.) tree farm where biosolids were applied at a rate of 380 metric tonnes per hectare in deep trench rows (46 cm deep, 107 cm wide, and 20 ...

Criconemoides Grassator N. Sp. From Yellow Poplar (Liriodendron Tulipifera) in West Virginia 1)

Nematologica, 1967
Soil and root samples from a native stand of yellow-poplar yielded Criconemoides axeste Fassuliotis & Williamson, 1959, and an undescribed representative of Criconemoides Taylor, 1936. The predominant species, C. grassator n. sp. differed from all the other representatives of the genus, except C.
