Abstract: Scales from inner, middle and outer layers of 2-year-old L. pumilum bulbs were propagated different stroma under different air temperatures and light intensities. Results showed that the most important factor influencing bulblet quantity and diamiter was temperature and light intensity, followed by scale position.Bulblets grew best at 25℃ and dark condition. Stroma had no impact on bulb propagation. Middle and outer layer scales produced more bulblets than inner ones, and average diamiter of bulblets produeced from middle and outer layer scales was larger than those from inner ones. Scales almost withered after 40 days. Weight of per 100 scales and quantity of bulblet has positively correlation to bulblet diameter. Under same condition, the quantity of bulblet reproducted by the section cut with knife is remarkablely higher than by the section broken off with hands.

Key words: Lilium, temperature, light intensity, propagation
