抄録
The effects of canopy gaps on seedling emergence and growth of Cornus controversa and Prunus grayana were studied in a 21-year-old Cryptomeria japonica plantation. The seeds of the two species were sown in December 1995 and their fate was followed until March 2000. P. grayana germinated in 1996, but C. controversa germinated in 1997. In both species studied, more than 70% of the seedlings survived in the forest edge until the end of the experiment, although none survived in the forest understory in the first growing season. In the gap, the survival rate was higher in P. grayana than in C. controversa. In this experiment, some trees were cut to enlarge the area of the gap, in which the growth rate increased markedly for C. controverse seedlings, but not P. grayana seedlings after the cutting, These two species showed substantial differences in the patterns of seedling emergence, survival and growth in a Cr. Japonica plantation which had a canopy gap.
