After strip cutting was performed in July and September 2005 and in March 2006, we counted the number of culms and undeveloped bamboo sprouts and found that there were three bumper years and two bad years during a 5-year period. The number of sprouts, culms, and undeveloped bamboo sprouts increased over time. The number of undeveloped bamboo sprouts in bumper years was more than that in bad years, and the same tendency applied to the percentage of undeveloped bamboo sprouts. The number of undeveloped bamboo sprouts in a plot cut in March was greater than those in plots cut in July and September. There might be a relation between the cutting season and the generation of bamboo sprouts. On the other hand, in the control plot, the percentage of undeveloped bamboo sprouts in bumper years was lower than that in a bad year. The result for the control plot was opposite that for the cutting plots. The cutting plots had not recovered before strip cutting, and the number of undeveloped bamboo sprouts increased gradually; thus, we must continue to investigate this site to confirm a relation between cutting season and sprout generation. 鹿児島大学 Kagoshima University 2011-03-01 jpn departmental bulletin paper VoR http://hdl.handle.net/10232/12659 https://ir.kagoshima-u.ac.jp/records/10905 13449362 AN10592752 鹿児島大学農学部演習林研究報告 Research bulletin of the Kagoshima University forests 38 13 17 https://ir.kagoshima-u.ac.jp/record/10905/files/AN10592752_v38_p13-17.pdf application/pdf 577.9 kB 2016-10-31 2011-03-01
