This is a general review of the physiology of the hardening-off process, and of frost resistance as applied to Mediterranean woody species that are to be used for afforestation. The different sections of the paper look at bud dormancy, the hardening-off of Mediterranean species - including...

Agroforestry, as a topic to address the intersection of agronomy, ecology, genetics, and social sciences, obliges to rethink plant improvement. We propose to use the new term oïkosbreeding or Ecobreeding to emphasize the need of considering the whole ecosystem. The term refers to both place and...

Wild plant species related to our crops (crop wild relatives, CWR) are an indispensable genetic resource for plant breeding. At the same time, they are important components for ecosystems and for ecosystem services. Like many other species, they are increasingly threatened by climate and...

The oak-hickory and oak-pine forest types dominate much of the southern landscape. In the Blue-Ridge and Appalachian Mountains of western Virginia, oak as a percentage of total forest volume can be as high as 60 percent. Much of this forest type is represented by older aged cohorts with little...

Longleaf pine (Pinus palustris) seedlings grown from seeds collected from two seed orchards in 2014 showed evidence of hybridization with loblolly pine-as much as 80 percent had some stem elongation in the container nursery. This stem elongation, however, was not to the extent that has typically...
