萱草不同品种杂交亲和性及其种子萌芽力研究

[目的]为萱草的种植及繁育提供参考方法。[方法]以单瓣大花萱草品种（n-1、n-2、n-3、n-5、0603）、小花品种（sf-2、sf-4、sf-6、金娃娃）和复瓣品种sf-11为材料,分别对其进行杂交、人工自交和天然自交,考察各品种的结实率、单果种子数及种子出苗率;同时研究不同播期对sf-6种子出苗率的影响。[结果]杂交组合中,金娃娃×sf-6座果率最高（17.1%）,人工自交组合中,sf-6结实率最高（70%）;0603、n-1、n-2、sf-2人工自交均可坐果,但自然授粉不结实,n-5和sf-11人工授粉和自然授粉均不结实;大花品种单果种子数多于小花品种;n-3自花授粉种子发芽率最高（72%）;8月以前播种sf-6出苗率较低（30%以下）,8月底播种出苗率最高（57%）。[结论]不同萱草品种结实率和发芽率不同,8月以后播种萱草出苗率较高。

Study on Cross Compatibility of Different Hemerocallis Varieties and Their Seed Germination Force

[Objective] The study was to provide the reference method for planting and breeding of hemerocallis.[Method] With simple-petal-and-large-flower hemerocallis varieties(n-1,n-2,n-3,n-5 and 0603),small-flower varieties(sf-2,sf-4,sf-6 and hemerocallis stella deoro) and double-petal flower variety sf-11 as the materials,they were artificially crossed,artificially self-pollinated and naturally self-pollinated,and then their seed setting rate,seed number per fruit and seed sprouting rate were investigated,and at t...
