三色堇引种栽培试验

Study on Introduction and Cultivation of Viola tricolor

对沈阳地区引进的6个三色堇品系(大花、花脸、水晶、美国丽人、英国帝王、日本神童)进行栽培试验,观察其播种出苗情况和茎、叶、花等植物学性状。结果表明,三色堇出苗率除品种LRB外,其余均可以达到50%以上,尤其是LRW、LRX和DWY的出苗率最高,达100%。种子出苗后均能正常生长和开花,但是大花、花脸及丽人系列抗病能力较弱,易发生病害;神童系列花径特别大,且具有艳丽的条状或块状色斑,抗病性比较强;水晶系列花径小,观赏效果好,具有推广价值。

Six lines of pansy, including B 1 .B3.S.LR.DW.ST were introduced and cultivated in Shenyang city, and the germination percentage, the character of stem, leaf and flowers of theses plants were observed. The results showed that the germination percentage of pansy was over 50 % except LRB, especially LRW,LRX and DWY with the germination percentage of 100 %.All of the introduced cuhivars could grow and flowering normally, but disease resistances of B 1 ,B3 ,LR were the weakest. The line named ST had larger flowers, vivid colors, strong disease resistances, and the line named S had smaller flowers, elegant poise, decorative values.So both ST and S were worthy of expanding.
