Responses of Crown Development to Canopy Openings by Saplings of Eight Tropical Submontane Forest Tree Species in Indonesia: A Comparison with Cool-temperate Trees

摘要

• Background and Aims Growth in trunk height in canopy openings is important for saplings. How saplings increase height growth in canopy openings may relate to crown architectural constraints. Responses of crown development to canopy openings in relation to trunk height growth were studied for saplings (0·2–2·5 m tall) of eight tropical submontane forest tree species in Indonesia. The results of this study were also compared with those of temperate trees in northern Japan.
