Effects of Soaking on Seed Germination and Seedling Growth in TwoProvenances of Toona ciliata var. pubescens

Seeds of Toona ciliata var. pubescens were collected in November 2013 in Guanshan National Nature Reserves and Jiulianshan NationalNature Reserves, Jiangxi province, and were field sowed in April 2014. Experiments were conducted on different seed soaking time before sowing.The results showed that under same sowing time, germination rate and seedling growth of Guanshan provenance was greater than that of Jiulianshanone, but ground diameter was the opposite. Seeds soaked by 20 hours had better germination rate and seedling growth, but had no significant effect onground diameter growth.
