本研究通过设置不同的预处理、播种基质、光照和温度条件,对中国秋海棠属(Begonia L.)4种植物:心叶秋海棠(Begonia Labordei Lévl.)、圭山秋海棠(B. guishanensis SH Huang & YM Shui)、粗喙秋海棠(B. crassirostris Irmsch.)和兰屿秋海棠(B. fenicis Merr.)进行种子萌发特性研究.结果表明:低温预处理对种子萌发无显著性影响,用赤霉素溶液浸泡种子6 h后能明显促进种子萌发,提高种子萌发率和萌发势,但对不同的种其最有效的浓度亦不同.其它条件均能显著影响秋海棠属植物种子萌发. |

In this paper seed germination characters of four species ( Begonia Labordei LeVl. , Begonia guishanensis SH Huang & YM Shui, Begonia crassirostris Irmsch. and .6. fenicis Merr. ) of Begonia from China were studied by setting different conditions such as pretreatments, substrates, light and temperature. The results of the test of germination were as follows: Low temperature pretreatment almost had no effect on seed germination. However, Germination of the seeds which were soaked in GA for six hours was distinctly facilitated , the seed germination rate and germination vigor were also increased, but the most effective concentration varied with different species. The other conditions could affect the seed germination distinctly. |
