Abstract The effects of different defoliation intensities and frequencies
were studied on regrowth and herbage mass of Leymus chinensis
and Hordeum brevisubulatum in northeast China for two years.
Plants were defoliated to 6, 8 or 10 cm stubble height by removing
about 40% of growth down to each designated defoliation height. In
the first year, L. chinensis was defoliated 22, 17 or 13 times, and in the
second year was defoliated 21, 15 or 15 times to reach 6, 8 or 10 cm
stubble height treatments, respectively. H. brevisubulatum was defoliated
26, 21 or 15 times in the first year, and… More >
