Effects of Temperature on Seed Germination of Dalbergia tonkinensis

  • Received Date: 2014-02-21
  • The effects of temperature on seed germination characteristics of Dalbergia tonkinensis collected from Lang son of Vietnam were studied. Significant differences were found among treatments in terms of germination percentage, germination energy, germination index and average germination time. In range of 15 ℃ to 30 ℃, the germination rate, germination energy and germination index increased with the increasing temperature, while the average germination time decreased correspondingly. And all germination parameters achieved the highest or the lowest values under the germination temperature of 30℃ with mean germination percentage, germination energy, germination index and germination time being 84.70%±8.4%, 65.56%±6.9%, 42.39±5.0 and 6.3±0.0 days, respectively. While under 35℃, the seed germination was inhibited slightly, most germination parameters were significantly lower than those in 30℃ except the average germination time. It could be concluded that 30℃ was the optimum temperature for seed germination of D. tonkinensis.
