Reports that glyphosate applied during April or May in hybrid poplar plantations usually results in tree growth increases and that later summer applications often result in tree damage, growth loss, or mortality.

We studied the impact of glyphosate tolerance on weed control and tree growth in field-grown transgenic poplars. Using Agrobacterium-mediated transformation, we produced 94 transgenic transformation events in four hybrid genotypes (three Populus trichocarpa × P.

deltoides and one of P. trichocarpa × P. nigra). Genetic variation and genetic relatedness have been studied at the molecular level in only a limited number of Populus species, but an excellent example is an on‐going study of P. nigra, the native European poplar, where plants from across widely differing European climates have been collected and grown in several European lar genetic analysis has been employed to determine Cited by: Stand density directly affects the distribution of ecological factors such as light, heat, and water in forest communities and changes the diversity and structure of undergrowth species, thereby affecting soil health.

Fine roots can provide water and nutrients to plants rapidly in the fierce competition of soil resources, so as to get rid of environmental factors. This study examined the fine Cited by: 2.

Resorption efficiencies of these experiments ranged from 35 to 52% for the willow hybrids and 0–32% for the hybrid poplar, compared to the near 50% reported in the literature for deciduous forest ecosystems (Aerts, ; Vergutz et al., ) and 23–60% reported for hybrid poplar plantations (Brown and van den Driessche, ).

However, there is limited understanding of the climatic sensitivity (e.g., degree of drought tolerance) of hybrid by: In poplar, a glyphosate tolerance transgene, CP4, was stable for over 8 years under field conditions and nearly all instability was observed during in vitro growth only.

Glyphosate tolerance in birdsfoot trefoil was identified in plants from the cultivar Leo, plants regenerated from tolerant callus, and selfed progeny of plants regenerated from callus.

In temperate and boreal regions, perennial trees arrest cell division in their meristematic tissues during winter dormancy until environmental conditions become appropriate for their renewed growth.
