摘要：温度是影响种子萌发的主要因素，也是决定种子萌发速度的首要条件，适宜的发芽温度是种子萌发所必需的环境条件之一，摸清种子萌发的适宜温度对指导农林业苗木生产实践具有重要意义。不同植物的种子由于习性、生境和生理生态学等方面的差异，其最适的发芽温度差异较大。
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 percent- age, germination energy, germination index and average germination time. In range of 15 ℃ to 30 ℃, the germina- tion 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 val- ues 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, respec- tively. While under 35℃, the seed germination was inhibited slightly, most germination parameters were signifi- cantly lower than those in 30℃ except the average germination time. It could be concluded that 30℃ was the opti- mum temperature for seed germination of D. tonkinensis.
