Analysis of relative light (percentage of above-canopy light) to Pinus taeda, Liquidambar styraciflua, and Andropogon virginicus at three-fourths plant height in mid-June, as influenced by densities of each species.
All four sites contained open (20 to 40%) canopies of longleaf pine with well-developed groundcover vegetation dominated by Andropogon virginicus L.
As in south Mississippi, canopy coverage above these edge populations ranged between 20 and 40%, and the groundcover vegetation was dominated by Andropogon virginicus and Schizachyrium scoparium and numerous forbs indicative of open woodlands, barrens and savannas.
One of the two trays was sown with a mixture of approximately 1000 seeds of Andropogon virginicus.
graminifolia grown from seed and surrounded by established swards of Andropogon virginicus showed lower incidences of floral induction than did comparable shoots of P.
