宿根福禄考的系列新品种

New Cultivar Series of Summer Phlox

福禄考属植物白花、异花均可授粉,通常结实率极低,通过人工不定向杂交辅助授粉措施可提高种子结实率。利用杂种实生苗的观赏性状和抗性变异性较大的特性,经过长期栽培观察,从中筛选出适应性强、花期长、花色丰富、色彩鲜艳的10个优良单株,通过组培快繁和嫩枝扦插繁殖技术将其扩繁为10个单株无性系。这10个优良品种适宜在长江以北地区露地或盆栽栽培观赏。

In cultivation summer phlox can be self and cross fertilized but with low seed setting rate. We raised the seed setting rate by random supplementary artificial hybridization among the species Phlox panicvlata and several of the summer phlox cultivars. Through a long period of cultivation and observation of the resulted hybrid seedlings, which showed a great variability in ornamental characters and resistance, 10 supperior individuals with good adaptability, long flowering time, and bright flower colours were selected. They have been multiplied by in vitro rapid propagation and soft wood cutting to establish 10 clones as new cultivar, which are suitable for outdoor and in pot cultivation in gardens throughout the wide areas north of the Yangtse River in China.
