Relating Seed Treatments to Nursery Performance: Experience with Southern Pines
Producing good quality seeds that perform well in the nursery continues to be challenging. High quality conifer seeds are obtained by optimizing collecting, processing, storing, and treating methodologies, and such quality is needed to consistently produce uniform nursery crops. Although new technologies are becoming available to evaluate seed quality, they have not been developed to the extent...
متن کاملGermination pattern of naturally grown Lathyrus and Vicia species to different methods and seedbeds
In many forage legumes, hard seed coat is the main problem impeding thegermination by preventing water and gases transport in seed. We evaluated theeffects of mechanical scarification, chilling, different seedbeds (peat and sand) andtheir combination on the germination ratio and time of 9 naturally grown legumespecies belonging Lathyrus and Vicia genus. Control seeds showed very lowgermination ...
متن کاملUpper Coastal Plain of southeastern Arkansas, USA
To contribute to an understanding of forest management on secondary forest succession, we conducted vegetation surveys in a chronosequence of pine stands ranging in age from 1 to 59 years. Adjacent areas were compared at 1, 7, 12, and 17 years following two reproduction cutting methods (clearcuts or pine seed-tree cuts); a 59-year-old pine stand that was periodically thinned was also included t...
متن کاملEffects of Reproduction Cutting Method and Hardwood Retention on Shortleaf Pine Seed Production in Natural Stands of the Ouachita Mountains
Shortleaf pine (Pinus echinata Mill.) seed production was monitored for 4 yr in stands harvested by a range of evenand uneven-aged reproduction cutting methods. The fifty-two 35–40 ac stands were distributed throughout the Ouachita Mountains from central Arkansas to eastern Oklahoma. Seed crops were characterized as good, poor, poor, and bumper, averaging 109,000, 18,000, 5,000, and 379,000 sou...
متن کاملArtificial Regeneration: an Essential Component of Longleaf Pine Ecosystem Restoration
Regenerating longleaf pine by artificial means is an essential component of restoring the ecosystem across most of its range because there are limited acres of longleaf stands remaining. Establishing longleaf pine is an early step in the ecosystem restoration process. An overview discussion of artificial regeneration techniques and related issues are presented this paper. Other papers follow in...
