EFFECT OF ROOT EXCISION ON COMPETITIVE ABILITY AND YIELD OF WINTER WHEAT [PDF]

open access: yesChinese Journal of Plant Ecology, 2007
Aims Decreasing root biomass might be an effective way to increase crop production under drought stress. A winter wheat with root excision was chosen to determine whether 1) root biomass or R/S (root/shoot ratio) is reduced by root excision, 2) competitive ability is reduced by root excision and its link with R/S and 3) competitive ability influences ...
