A Preliminary Study on Methods for Dormancy Breaking of Seeds of Lepidium Perfoliatum L.Cultivated Outdoor
摘要
Abstract
[Objective]Methods for dormancy breaking of seeds of Lepidium perfoliatum L. cultivated outdoor were preliminarily explored to lay abundance material foundation for further study of characteristics of seed mucilage of L. perfoliatum and agriculture cultivation and development of this quality pasture. [Method ] Seeds from L. perfoliatum cultivated outdoor were treated with different chemical and physical methods to measure germination rate of its seed. [ Result] (1) Seeds treated by 4 ℃ , CA3 and H2O2 respectively and by combination of GA3 and H2O2 treatment could break the dormancy . (2) Combination of GA3 and H2O2 treatment was the most effective method to break seeds dormancy of L. perfoliatum .Seeds treated with 500 mg/L CA3 for 3 days followed by 15 % H2O2 for 20 min had the higbest germination percentage . [ Conclusion]The results suggested that the embryo vigor of seeds from L. perfoliatum cultivated outdoor may be not strong enough to get rid of the mechanical obstacle of the seed coat which lead to seed dormancy .关键词
