摘要
研究了储藏条件和萌发温度对波叶海菜花种子萌发的影响。将波叶海菜花新鲜和风干种子分别在04、、10℃及15℃下贮藏120 d,在25℃下进行萌发试验。结果表明,风干的种子全部不萌发。新鲜种子在10℃及4℃储藏,种子萌发率高,没有显著差异;而在0℃下储藏的种子萌发率显著降低。并在15、20、25、30℃下对波叶海菜花进行萌发试验,发现种子在所有温度条件下均有较高的萌发率(>90%);温度越高萌发时滞越短,萌发持续时间越短。基质对种子萌发没有显著影响。
The effects of storage condition and germination temperature of Ottelia acuminata var. crispaseeds were studied in order to find suitable store ways and germination condition. The author examined the germination after 120 days of dry and miost storage under 0℃, 4 ℃, 10℃ and 15 ℃ respectively. The result showed that germination of O. acuminata var. crispa was affected by storage conditions remarkably and the optimal range was 10℃ to 4℃ ,while the germination percentage of seeds was lower under 0 ℃. The seeds did not germinate when the duration of storage was dry. At the same time,the author tested the germination of seeds of Otteliaacuminctta under 15 ℃ ,20 ℃ ,25 ℃ and 30℃. The germination could germinate in an abroad range of temperature. Seeds of O. acuminata var. crispa showed higher germination under 15 ℃ to 30 ℃ regions. The germination speed increased gradually with rising of temperature. Substance had no significant effect on percentage germination.
