摘要
采用刀片破皮、低温冷冻、60℃热水浴及干燥、碱液处理、浓硫酸加搅拌等方法处理野生大豆种子,研究其对野生大豆种子发芽和胚生长的影响。结果表明:经过刀片破皮和浓硫酸加搅拌处理的各项萌发指标远高于对照(P<0.05);综合野生大豆幼苗的萌发指标和胚根长、胚芽及鲜重等指标,破皮和10 m in浓硫酸加搅拌处理最有利于野生大豆种子萌发;冷冻处理的各项萌发指标显著低于对照(P<0.05),与常温保存相比,冷藏保存野生大豆种子的千粒重和发芽率有所增加。表明冷藏保存可以提高野生大豆种子的质量;常温下野生大豆休眠期为7个月,冷藏保存野生大豆的休眠期为8个月。
The seed of wild soybean( Glycine soja) belong to hard seed. Its germination percentage was very low with general methods. The effect on seed germinations and embryo growth by using machinery method of damaging seed coat, freezing, 60℃ hot water bath and dryness, lye and soaked in concentrated sulfuric acid and stirred were studied in this paper. The resuits showed that the germination rate, viability and index with the machinery method of damaging seed coat , sulfuric acid and stirred were higher than that of the control (P 〈 0.05). Integrate the experimental results of germination percentage, germination index and seedling growth of wild soybean, the best result was obtained when the seeds were soaked in concentrated sulfuric acid and stirred for 10 min. The germination percentage, germination viability and germination index with freezing treatment were lower than that of the control. Compared with room temperature, thousand seed weight and germination percentage increased under cold storage. The dormancy period of Glycine soja under room temperature and cold storage was 7 and 8 month, respectively.
