Establishing provenance, viability-testing standards and enhanced germination for seed production of wiregrass in Florida

 Final report for R-003-07 Objective #1 Create a standard viability test of wiregrass – An accurate method to determine viability is an essential prerequisite to germination testing since germination tests need to be corrected for the percentage of viable seeds. Objective #2 Identify Optimal Regimes to Promote Germination of Wiregrass – Initial viability tests of…

Assessing Potential Loss of Coreopsis leavenworthii Genetic Diversity under Commercial Seed Production and Gene Flow from Coreopsis tinctoria.

 The objectives of this project are to assess (1) the potential loss of genetic diversity (or genetic shift) during seed production of C. leavenworthii, and (2) potential gene flow from C.tinctoria to C. leavenworthii, two important issues in production and use of C. leavenworthii seeds. We have made excellent progress toward these objectives and have…

Literature Compilation: Problematic Plant Species for Wildflower Establishment

Seed sowing is often the most economical means of establishing wildflower plantings in landscape and natural settings. However, competition from noxious weeds or aggressive native species that co-exist on a site can present major limitations to wildflower seedling establishment in restoration and landscaping settings. Wildflower planting failure is sometimes expressed as decreased aesthetic value in…
