摘要
对3种山矾科树种(四川山矾、黄牛奶树、棱角山矾)进行播种、扦插繁殖试验。结果表明:①3个树种进行播种繁殖,种子萌发十分困难,有隔年萌芽的性状,繁殖速度缓慢;②激素会影响3个树种的扦插成活率,但对不同的树种产生的影响也不同;③利用不同激素及其不同的浓度梯度对3个树种的插穗进行处理,会对它们的扦插成活率产生不同的影响,说明试验条件下使用激素处理能够影响树木的萌生潜能。
Propagation experiment of three Symplocaceae species （Symplocos setchuensis, Symplocos laurina and Symplocos tetagona Cheu） was conducted by using sow and cuttage techniques. The results showed that： ①Seedling germination of Symplocos setchuensis, Symplocos laurina and Symplocos tetagona Chen were very difficult with following years bud traits, which led to slow breeding rate; ②Hormone had effects on cutting survival rates of the 3 species with different influence on different species; ③Different hormones with different concentration gradient had different effects on the cutting survival rates of three tree species, which indicated hormone treatment could affect germination potential of cutting in lab.
