Self-reproducing bulblet of lily ‘Siberia'were used as materials to study variation effect of different treatment factors on bulb vigor index.The results showed that:low temperature at-2℃ and 2℃induced bolting,accelerated vigor expression of bulblet;treatment duration in 135-165 dwas the best for vigor expression;5-8g large size bulblet performed overall strong vigor;and culture bulblet for more than 5.5months could obtain bulblet in high vigor.With two quadratic regression orthogonal rotation combination analysis,heat treatment at 37℃for 3h was optimal on bulblet vigor index.Heat-treatment stored up energy in bulblet for its vernalization at low temperature.
