Abstract: In order to improve the applicability of test tube lily bulblet, the effect of low temperature stratification on the expression of small bulblet‘Siberia’was studied. The results showed that: -2℃ and 2℃ temperature treatments could effectively improve the germination rate, vigor index, breaking capacity and bolting rate of test tube bulblet. The study indicated that low temperature stratification of 135-165 d was the best vigor expression period, and through the promotion of bolting, could be highly related (correlation coefficient 1.00**) to improving lily (6-9 cm circumference) harvest rate. Low temperature stratification is an indispensable measure in achieving activity of the test tube lily bulblet cultivated in the field.
