Abstract:With artificial fertilization,the morphological responses of experimental clonal populations of Glechoma longituba on different nutrient supply conditions were studied.The results show that fertilization can obviously increase clonal growth.At the condition of fertilizing,the clones have powerful ability of branching,longer stolon length,bigger total biomass,shorter stolon internode length,smaller relative leaf area,thicker laminas and shorter petioles.Without fertilizing,the morphological characters ar...
