摘 要：Background:Alfalfa is a globally important forage *** are characterized by fall dormancy(FD).FD affects biomass yield and winter survival and is used to identify appropriate growing regions of *** has historically been assessed by measuring the natural height of regrowth in autumn of spaced plants in the *** commercial alfalfa is normally grown as a solid planted sward,FD could be different if plants were grown under real production *** objective of this experiment was to assess whether FD ratings obtained from swards were similar to those obtained on spaced ***:We evaluated 20 alfalfa cultivars in field trials established in 2015 at five locations in the United *** harvested the trials in early autumn and measured regrowth plant height approximately 3 weeks later in 2015 and ***:Autumn plant height responded as expected for the established check cultivars in all *** dormancy ratings for cultivars under both management systems were highly ***:Estimating FD from spaced plant height measurements in autumn is very robust,and using height data from sward plots gives equivalent results to that measured in spaced plant *** finding has many practical advantages.
