摘要
华北驼绒藜野生群落中存在明显的种内生殖差异 ,对 4种类型华北驼绒藜的生殖生物学和生产性能的研究结果表明 ,高产、早熟类型华北驼绒藜 (T- 1 - A)种子产量高 (6 9.0 g/株 ) ,株型紧凑 ,生育期短 (1 5 1 d) ,千粒重 (2 .6 4 g) ,结实率(79.7% ) ,饲草产量 (1 4 0 g/株 ) ,种子成熟度 (83% )明显高于晚熟类型 。
Ceratoides arborescens exists remarkably reproductive differences in wild groups. The result of study in reproductive biology and productive properties showed that Ceratoides arborescens (T 1 A) of high production and early ripening types has short bearing period, which had the advantage over late mature types in weight of seed per plant (69.0g), weight of per 1000 seeds (2.64g), seed setting percentage (79.7%), forage volume per plant (140g), maturity of seed (83%), and has higher productive properties and prospect of breeding.
