Abstract:
The cultivated and wild seeds of Datura stramonium were used as materials to explore the effect of different concentrations of GA3,NAA,2,4-D and IAA on seeds germination and seedling growth by seed soaking.The results showed that after soaking seeds with GA3 at 90 mg?L-1 for 24 hours,the germination rate and fresh weight,dry weight,root length and root surface area of the cultivated and wild seeds were significantly increased.After soaking seeds with NAA,the seed germination and seedling growth of two kinds of seeds were promoted at low concentration(10-6-10-8 mol?L-1),while the germination and seedling growth were inhibited at high concentration(10-5-10-4 mol?L-1).When the concentration of 2,4-D was 1.0 mg?L-1,the germination rate and seedling growth of wild seeds increased significantly,while that of cultivated seeds was the best at 5.0 mg?L-1.After soaking seeds with IAA,the germination rate and seedling growth of the cultivated and wild seeds reached the maximum at 25 mg?L-1.In a word,the germination rate of cultivated seeds was the highest under 10-8 mol?L-1 NAA treatment,while the seedling growth was the best under 25 mg?L-1 IAA treatment,and 25 mg?L-1 IAA was the best treatment for germination rate and seedling growth of wild seeds.This study would provide a theoretical basis for planting and popularizing Datura stramonium L..
