Abstract
To clarify the characteristics of clonal growth ofMallotus japonicus, we excavated all roots of this species in a plot and ascertained the connections between shoots. All shoots examined were ramets that originated from roots. Young ramets grew in shady sites as well as sunnier sites, indicating that ramet production was not dependent on local light conditions.
