KOBAYASHI, Katsumi (Seikogakuin, Shizuoka) 1979. Studies on the growth and maintenance of patch of Miscanthus sinensis Anderss. I. Dynamics of shoot population and its relationships to expansion of patch area. Jap. J. Ecol., 397-401. The relationships between the dynamics of shoot population and the expansion or increment of patch areas of M. sinensis were investigated for two years from 1975 to 1977. A few of new shoots emerged at early spring and the main shoot gain was observed from early summer to late autumn. The latter period corresponded to the expansion period of patch area. But the course of areal increment of patch did not agree with that of shoot gain. The contributory rate of new shoot to patch area increment showed a remarkable seasonal variation. Three tillering times were distinguished during this period, and this suggested that the three tillerings formed different distributional patterns of new shoots from each other. The course of shoot loss had three peaks in a year, early summer, autumn, and winter. These shoot loss little affected the patch area. Many of the secondary and the tertiary tillers were overwintered, and these overwintered shoots played an important role in the ear production of shoot population.
