Abstract:

To provide the theory and practical technology for introduction, domestication and cultivation of Trollius chinensis Bunge, the effects of the treatment time of different concentrations GA3, storage time in 4℃, different temperature and soil matrix on germination of T. chinensis seeds were researched. The results showed that: (1)The dormancy of T. chinensis seeds were broken at 4℃ temperature in sands or GA3 treatments. 40~50 days was the best time to relieve Trollius chinensis seeds dormancy in sands at 4℃ temperature. The treatment of 150 mg/L GA3 for 3-4 days, 250 mg/L GA3 for 2-4 days and 350 mg/L GA3 for 2 days were the better way to relieve dormancy. (2)The germinating time, gemination rate and growth of seedlings were influenced by different temperature. It was suppressed by 30℃ or higher than 30℃ and was delayed by 10℃; 15℃ and 20℃ were the most suitable temperature and which were also promoted by 25℃. (3)Different soil matrix influenced geminination of Trollius chinensis seeds. The germination rate were sands>mixture ground mass one(mixture of sands and soil by 2:1 , leaf mold>mixture ground mass two(mixture of sands and soil by 1:2)respectively.
