Abstract:

In order to explore the planting of Fritillaria unibracteata at different altitudes, to expand its industrial development space and slow down the contradiction between its output and market demand, and pot experiments were carried out at 5 altitudes(i.e., 1174m, 1784 m, 2371 m, 3076 m, and 3413 m above the sea level respectively). The results indicated that both germination and leaf spreading stages of F. unibracteata significantly advanced with the decreased altitude(P<0.05). The withering stages significantly advanced with the decreased altitude(P<0.05), but they were not significantly different(P>0.05) between high altitudes (i.e., 3 076 and 3 413 m). The length of growing season increased first and then decreased with the decreased altitude, and the longest growing season was(114.83±3.59) days at 3 076 m. Both the plant height and single leaf area increased first and then decreased with the decreased altitude, and the maximum values were(11.00±0.70) cm and (7.71±0.87) cm2 at 2371 m. The lengths of bulb transverse axis and longitudinal axis increased first and then decreased with the decreased altitude, and the maximum values were(10.63±0.87) mm and (12.11±0.72) mmat 3 076 m. The results showed that, considering the length of growing season and bulb size of F. unibracteata, low altitude cultivation could be carried out in the range of 2 371-3 076 m.
