ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of light intensity on photosynthetic characteristics and seedling growth of Prunella vulgaris under different light intensity.</p><p><b>METHOD</b>The seedling of P. vulgaris was shaded with shading net, and relative parameters were measured. The data was statistically processed.</p><p><b>RESULT</b>With the reducing light intensity, the young plant stems became slender, the leaf long increased. The plant height and net growth under 42% full light condition were significantly higher than those under the other light intensity, chlorophy II and carotenoid contents increased, as well as Chl a/b decreased under low light. Photosynthetic indicators of P(n), T(r) decreased under low light, but CO2 concentration increased, and G(s) content decreases and then increased under 10% full light intensity.</p><p><b>CONCLUSION</b>P. vulgaris manifested the different plasticity and adaptability under different light intensities. The 42% light intensity was the best and the proper shading would promote the growth of seedlings.</p>
