Abstract
The effects of shading on plant growth and leaf microstructure of Thunbergia grandiflora (Rottl. et Willd.) Roxb. and T. Laurifolia Lindl. were studied. The results showed that the height of plant, length of internode ,chlorophyll content and the leaf tissue structure loose ratio ( SR ) increased, but chlorophyll a/chlorophyll b, thickness of leaf, palisade tissue and spongy tissue, the tissue structure tense ratio ( CTR ) decreased.
