Germination of Range Plant Seeds at Alternating Temperatures

Abstract

2. was concluded that: Removal of 90% of the current herbage at any stage of plant development was detrimental to further root and herbage growth. Removal of as much as 30 and 60% of the current herbage at any stage of plant development was not detrimental to subsequent root and herbage production when compared with yields from unclipped plants. T1 prom this study, the effects of herbage removal on first-year plants of cane bluestem are related to the degree of utilization, but show no definite correlation with the stage of development. This study was conducted in a greenhouse under more or less optimum growing conditions. Further testing under field conditions may introduce considerations not evident here. Nevertheless, it demonstrated that, under the conditions specified, firstyear plants of cane bluestem could withstand herbage removal of as much as 60% at very early stages of seedling development as well as later without undue harm to the plant and subsequent growth.
