ABSTRACT
<p><b>OBJECTIVE</b>To find out the optimal condition for the germination by studying the effects of light, temperature, seed soaking and cultivation condition on Platycodon grandiflourm, and offer the basis for standardized culture of P. grandflorum.</p><p><b>METHOD</b>The rate of water absorption of the seed was determined. The germination of P. grandiflorum seed was tested under following conditions treatments under different temperature (10,15,20,25,30 degrees C), light treatments (light and dark), seed soaking time (12,24,36 h) and different germination cultivation conditions (on filter paper, between filter paper, between gauze,on gauze).</p><p><b>RESULT</b>The water absorption of the seeds reached the maximal 120% within 36 h at 25 degrees C. The time of seeds soaking had limited effect on the germination of the seed, while temperature and light condition showed significant effects on the germination.</p><p><b>CONCLUSION</b>The optimal condition for the germination of the seed of P. grandiflorum is as followseed soaking for 12 h, and 25 degrees C underlight.</p>
