Description
Relationships among growth stage, herbage quality, and dry matter accumulation of reed canarygrass cultivars were investigated in a rainy mountainous district of Japan. Fiber content accumulated during the primary growth correlated with some growth characters of this grass, especially with preferential culm expansion, so that total amount of cell wall constituents reached a remarkably high level about the time when culm/foliage (C/F) ratio in dry matter was elevated above 1.5. In aftermaths, whose early regrowth went on rather quickly, dry matter accumulation began to decline at the stage that C/F ratio of standing crop became ca. 1.0 and fiber content exceeded 60 %. Although annual total yield decreased considerably as cutting frequency increased, cell wall constituents were lowered well enough, in spite of the essentially coarse character of the plant. Therefore, earlier harvestings both in primary and aftermath canopies seem to be of vital importance in better utilization of reed canarygrass cultivars.
