説明

Killinga brevifolia var. leiolepis is a major perennial weed in turf, and its growth pattern is similar to that of manilagrass, the most popular trufgrass species in Japan. Competitiveness between both species was assessed by means of a replacement series experiment. They were planted in soil-filled containers at 5 different ratios of 16: 0, 12: 4, 8: 8:, 4: 12 and 0: 16, and grown for 4 months in the field conditions. The number of shoots, the number and length of rhizomes, and the dry weight of shoots, rhizomes and roots were measured. Relative yields (RY) and the relative yield totals (RYT) were calculated using the biomass data. Shapes of the biomass RY curves of both species in replacement series diagrams indicated the extreme aggressiveness of K. brevifolia against manilagrass (Fig.1), the trend being severer in rhizomes than in shoots. RYT values less than 1.0 obtained in the mixture plots suggested that allelopathic interaction might take part in this interference. Growth of individuai plants presented by the numbers of both aerial shoots and rhizomes were reduced in K. brevifolia but increased in manilagrass at the higher proportions of the own species (Tables 1 and 2) . Aggressivity of K. brevifolia became apparent when the rhizomes of each plant began invading to the territory of the other but before crowded with the aerial shoots (Figs. 2 and 3) .
