紫红秋叶色木槭优良观赏种质资源调查分析

Investigation of Germplasm Resource of Mono Maple with Purple-Red Autumn Leaf Traits

以踏查、样线调查、定株观测和采种育苗相结合的方式,对张广才岭地区色木槭紫红秋色叶类型的资源状况进行了调查研究。结果表明,色木槭紫红变叶类型种群数量少,群落中个体比例低,但是在优势地点的群落内有一定的资源数量;紫红叶色单株在7年的观测期间表现出了稳定的叶色性状,而且这种秋季紫红叶色性状具有可遗传性,具有新品种选育和直接开发利用潜力。

Purple-red autumn leaf varieties of mono maple （Acer mono Maxim. ） in Zhangguangcai Mountains were investigated by combining the methods including spot observation, sample line survey, sample tree observation and seedling growing test. The results indicated that the population of purple - red autumn leaf variety was very small only with a few individuals, but showing a stable color - changing trait. This implies that this trait has the heritability and thus has the potential to be bred and directly developed and utilized.
