The genetics of drought tolerance in conifers

Web9 Apr 2024 · It is also important to note that logging degrades forest genetics by indiscriminately removing trees that may be resilient to drought, disease, insects, and fire. Among the criticisms of the Hagmann paper by Baker and co-authors is that most fire research and interpretation of historical forest conditions is based on fire scar studies. Web25 Feb 2024 · On the foreseen climate change context, breeding toward drought tolerance is necessary in order to ameliorate plant performance. Therefore, the aim of this work was to study the reproduction mechanisms of the strawberry tree, obtain new genetic combinations by hybridization, and select genotypes more tolerant to drought stress.

Web31 May 2024 · Genes associated with drought tolerance in plants have also been identified by assessing variation in gene expression in controlled experiments, including water-deficit stress treatments of genotypes with varying tolerance to aridity. WebBecause nursery stock had run short of native western red-cedar, project leaders chose to substitute a closely related conifer sourced from Oregon and northern California: incense cedar. This species is more drought-tolerant than western red-cedar, but all wild populations occur southward of Washington state.

WebThe use of genetics to improve drought tolerance and provide yield stability is an important part of the solution to stabilizing global production. That is why the devel-opment of maize varieties with enhanced tolerance to drought stress and higher water use efficiency (WUE) has become a high priority goal for major breeding programs, WebDrought is one of the major abiotic stresses seriously affecting cotton yield. At present, the main cotton-producing areas in China are primarily arid and semiarid regions.
