Rehabilitation of Understocked Loblolly- Shortleaf Pine Stands- III. Natural Stands Cutover 15 Years Previously but Unmanaged
Plots in an unmanaged loblolly-shortleaf pine (Pinus taeda L.-P. echinata Mill.) stand that had been cutover I5 yrpreviously were established to representfive stocking levels: 10, 20, 30, 40, and 50%. The stand was on a good site (site indexLob = 90 ft at 50 yr) and had uneven-aged character. Two competition control treatments (none and individual tree release using herbicide) were also assigne...
متن کاملDistinguishing features of loblolly and shortleaf pine seeds : implications for monitoring seed production in mixed stands
Monitoring seed production in mixed loblolly pinc shortlcaf pine (Pinus taeda L. and Pinus echinata Mill.. respectively) stands may require identifying individual weds hy species. Althuugh lublully pine seeds are UII average Ileavier and larger than thosc of shortleaf pine. there is considerable overlap in these properties for individual seeds. In this study the properties of six seer1 lnrs of ...
متن کاملEffects of Alternative Thinning Regimes and Prescribed Burning in Natural, Even-Aged Loblolly-Shortleaf Pine Stands: 25Year Results
In southeastern Arkansas, pine growth was monitored for 19 yr after mechanically strip thinning a dense, naturally regenerated, even-aged stand of Gyr-old loblolly pines (Pinus taeda L.) and shortleafpines (P. echinata Mill.) that averaged 16,600 stems/UC. Prescribed winter burns were conducted biennial ly between ages 9 and 20 yr and at 24 yr . Commercial th innings during the 17th and 23rd gr...
متن کاملYield Comparisons from Even-Aged and Uneven-Aged Loblolly-Shortleaf Pine Stands
Empirical yields for a 36year management period are presented for seven long-term studies on similar sites in loblolly-shortleaf pine (Pinus taeda L.-P. 1 The authors thank George Switzer of Mississippi State University, Terry Clason of Louisiana State Uni\'ersity, and Dick Kennedy of Georgia-Pacific Corporation for reviewing the manuscript. Special thanks also to Georgia-Pacific Corporation an...
متن کاملLoblolly Pine Ssr Markers for Shortleaf Pine Genetics
—Simple sequence repeats (SSR) are highly informative DNA-based markers widely used in population genetic and linkage mapping studies. We have been developing PCR primer pairs for amplifying SSR markers for loblolly pine (Pinus taeda L.) using loblolly pine DNA and EST sequence data as starting materials. Fifty primer pairs known to reliably amplify polymorphic markers in loblolly pine were scr...
