Abstract

One－year－old liana seedlings of Hedera nepalensis var. sinensis，Mucuna sempervirens，and Pueraria lobata were grown in full light （control） and three less than full light conditions：68% － 75% of full light （S1），40% － 49% （S2），and 10% － 21% （S3） with photosynthetic characteristics of light saturation point，light compensation point，total chlorophyll，chlorophyll a/b，and root－shoot ratio being studied. Results showed that the light saturation and light compensation points of M. sempervirens were highest，whereas P. lobata were both lowest. The light saturation point of H. nepalensis var. sinensis was high，and its light compensation point was low. In 10% － 21% of full light （S3），the total chlorophyll of P. lobata （2.888 mgg-1），M. sempervirens （2.242 mgg-1），and H. nepalensis var. sinensis （2.955 mgg-1） were highest. The chlorophyll a/b ratio in different light environments also showed strong differences. Additionally，the root－shoot ratio of the three liana seedlings in different light environments increased with increasing light. From these results，M. sempervirens was shade intolerant，P. lobata was shade tolerant for a narrow range of light，and H. nepalensis var. sinensis was somewhat shade tolerant for a wide range of light.［Ch，3 fig. 3 tab. 21 ref.］
