Tiller development of three bromegrass (Bromus) species following defoliation

摘要：

Bromegrass is widely grown for hay and pasture production in North America.Smooth bromegrass ( Bromus inermis Leyss ) and meadow bromegrass ( Bromus rip arius Rehm.) are the most commonly cultivated species and hybrid bromegrass ( B.rip arius X B.inermis) was recently developed in Canada.Meadow bromegrass has lower first growth yield than smooth, but higher regrowth yields (Knowles et al.,1993).The number of axillary bud and tillering ability were closely associated with smooth bromegrass regrowth ( Paulsen et al., 1969 ) and this may be the main reason for regrowth yield differences of bromegrass species following defoliation.The objective of this study was to determine tiller development in three bromegrass species following defoliation at two developmental stages.
