Effects of Herbage Removal on Seedling Development in Cane Bluestem

Abstract
This greenhouse study was divided into 2 phases: to determine the various ontogenetic expressions from germination to maturation; and to determine the effects of removing 30, 60, and 90% of herbage at various stages of plant development on subsequent development. Root growth was very slow until 12 leaves developed, after which both root and herbage growth proceeded very rapidly. Removal of 90% of current herbage at any stage of development was detrimental to further root and herbage growth. Thirty and 60% removal at any stage of development was not detrimental to subsequent root and herbage production when compared with yields from undipped plants. Thirty percent removal tended to increase root and herbage growth as compared with undipped plants, but the differences were not statistically significant.
