• Quantitative phenological measurements were taken on Ligustrum obtusifolium, a winter semi-deciduous shrub, growing under natural conditions at the edge and understory sites of a dense grove stand of Quercus actissima trees in a suburb of Mito, and of shrubs maintained under experimental conditions of 100%, 20% and 7% day light. Survivorship of the overwintering leaves was confirmed at every shaded study site, whereas at open sites all leaves had fallen before winter. This phenomenon seems related to the unfolding of large numbers of summer leaves during secondary shoot elongation, which increased markedly with increasing ambient environmental irradiance. This possibility was evaluated during the autumn to early winter period, through comparative examination of dormancy in buds and frost tolerance in leaves from each research site. Results suggest that, in the northern boundary regions of the warm temperate zone, the semideciduous habit of this shrub species results in it being well-adapted to a variety of habitat conditions, especially to various levels of irradiance.
