Abstract

Rhododendron fortunei lives in many kinds of forests in Mountain Tiantai (29°15' N, 121°06' E). Comparative analysis has been made on the architecture of R. fortunei saplings in the canopy gap of defoliated broad-leaved forest and in scrubs edge of the forest. The results showed that saplings in the canopy gap had thinner and narrower crown with longer branch, wider branch angle to horizon, lower bifurcation ratio and leaf angle to horizon, in comparison with those in the scrubs. All the differences were especially noticeable in the undergrowth. This indicated that the saplings would spread their leaves to receive more sunlight. Saplings had a low angle of leaves, and the leaves were smaller than those of the petiole, which made it possible for them to receive more scattered light. And the ratio of branch diameter, azimuths of branch and leaves had no significant difference. In addition, saplings mainly adopted monopodial branching, and the apical dominance was not evident. So the crown was characterized by sympodial branching in the canopy gap. It followed that the character of ramification of the R. fortunei had the relative stability, but in the two different habitats, bifurcation ratio, branch length, the angle of branch and leaf all varied significantly, and there was a certain tradeoff between the length of branch and the bifurcation ratio.
