To study the biological characteristics and find out the optimum condition for germination of seed of Thladiantha dubia Bunge for its standardized culturing.
The weight per 1 000 seeds, seed moisture content and seed viability were determined. The biological characteristics were studied and germination conditions of seed of T. dubia were tested under following conditions: different seed soaking time, different temperatures (15, 20, 25, 30, 35 degrees C) and different irradiation time (0, 5, 10, 15, 20 min).
The average length, width and thickness of T. Dubia seed were 4.96, 3.25 and 1.08 mm, respectively. The weight per 1 000 seeds was 14.03 g; the seed moisture content was 10.10%; the seed viability was 90.33%. Under the same condition of light, temperature and other factors, the seed germination percentage and germination energy were the highest after seed soaking 24 h. The suitable temperature range of seeds was form 25 degrees C to 35 degrees C. Under different irradiation time, the seed germination percentage and germination energy were the highest after irradiation 10 min. In different germinating beds, the seeds germination percentage and germination energy were the highest on paper (TP), which was 89.33%.
The optimum condition for the germination of the seed of T. dubia is seed soaking 12 h, irradiation 10 min, 25-30 degrees C on filter paper.
研究赤雹种子生物学特性，找出其种子萌发的最佳条件，为规范化种植提供依据。
测定赤雹种子千粒重、含水量及种子活力。研究其生物学特性，并在不同浸种时间、不同温度（15、20、25、30、35℃）、不同照射时间（0、5、10、15、20分钟）条件下对赤雹种子萌发条件进行试验。
赤雹种子平均长、宽、厚分别为4.96、3.25、1.08毫米。千粒重为14.03克；种子含水量为10.10%；种子活力为90.33%。在光照、温度等条件相同的情况下，浸种24小时后种子发芽率和发芽势最高。种子适宜温度范围为25℃至35℃。不同照射时间下，照射10分钟后种子发芽率和发芽势最高。在不同发芽床上，滤纸（TP）上种子发芽率和发芽势最高，为89.33%。
赤雹种子萌发的最佳条件为浸种12小时、照射10分钟、在滤纸上25 - 30℃。
