Study on the Seed Germination of Rhododendron delavayi

DUAN Xu et al(College of Forestry,Guizhou University,Guiyang,Guizhou 550025)  
[Objective] The study aimed to supply scientific basis for the germplasm conservation,development and utilization of Rhododendron delavayi.[Method] The germination experiment of R.delavayi seeds treated with different temperatures,different storage methods and seed soaking in warm water was conducted and their 1 000-seed weights and seed activities were determined.[Result] The germination speed quickened along with the temperature increasing and was highest at 30 ℃.The seed germination rates at 15,25 and 30 ℃ were 60 %,80 % and 95 % respectively.The germination rates of seeds soaked for 24 h and 48 h were 70 % and 88 % respectively,but that of dry sowing seeds was only 68 %.The germination rate of seeds that were air-dried and threshed and then stored at-30 ℃ was 84 % and that of seeds that were threshed and non-threshed and then all stored at room temperature were 77 % and 67 % respectively.[Conclusion] The suitable germination temperature of R.delavayi seeds was about 25 ℃.The germination rate of seeds soaked for 48 h was higher than that soaked for 24 h and that of seeds soaked with 20 ℃ water was some higher than that of dry sowing seeds.Air-drying,threshing and storage at low temperature could enhance seed germination.The formula concentration ratio of nutrient solution of 9∶1 was most suitable for the germination of R.delavayi seeds.
