匙叶翼首草不同海拔地区种子活力的研究

采用裂区设计研究了不同海拔地区匙叶翼首草种子在不同处理下的种子活力及最佳的发芽温度、光照等条件,为了大田生产的种子发芽和育苗提供理论指导。结果表明:在不同的处理下,不同海拔地区的翼首草种子经过50℃水浴处理20 min,在暗培养箱25℃恒温下培养,都能极好地提高其种子的发芽率、发芽势、发芽指数等指标;同时,在发芽与育苗试验中选用甘南碌曲双岔海拔较低地区的翼首草种子,种子的活力最高,引种驯化与人工栽培更易于成功。

Study on Seed Vitality of Pterocephalus hookeri(C.B.Clarke) Diels at Different Altitudes Area

Using split block design,the seed viability of Pterocephalus hookeri(C.B.Clarke)Diels under different treatments and the best germination temperature,light etc conditions were studied in different altitudes area,in order to seed germination and seedling provide theoretical guidance in field production.The results showed that under the different treatments,the seeds of Pterocephalus hookeri(C.B.Clarke) Diels of different altitudes,which were processed 20 min at 50℃ water bath,then were constant trained in 25℃ incubator in the dark could be improved their excellent seed germin nation rate,germination energy,germination index and other indicators.Introduction and domestication of cultivated was more easily and successfully if Pterocephalus hookeri(C.B.Clarke)Diels’ seeds in states shuangcha Gannan busy areas of low elevation were selected because of their the highest seed vigor,in germination and seedling trials.
