Productivity and quality of tall fescue and switchgrass under two harvest managements and different harvest intensities
… often becomes dormant in the hot summer months. Switchgrass (Panicum virgatum L.) has potential to supplement the limited carrying capacity of tall fescue in mid-summer. The objective of this study was to determine the seasonal dry matter distribution and quality of tall fescue and switchgrass as …

Genetic Improvement of Switchgrass Cell Wall Content, Leaf Angle and Flowering Time
Switchgrass (Panicum virgatum L.) is a candidate bioenergy crop. Somatic embryogenic (SE) calli are used for genetic transformation in switchgrass. A superior switchgrass line, HR8, was developed using recurrent tissue culture selection from cv. Alamo. HR8 SE calli were genetically transformable …
