摘要
为引进紫薇新品种,以美国紫叶紫薇为试验材料,开展紫薇引种栽培试验。通过调查生物学特性和物候期,选育出‘火红紫叶’、‘赤红紫叶’、‘银辉紫叶’、‘飞雪紫叶’和‘丹红紫叶’等5个紫叶紫薇优良品种。其花色分别为深红色、白色、浅粉红色,嫩叶为紫红色或灰紫色,成熟叶片黑紫色,且成熟叶色保持黑紫色不变直到落叶。试验结果表明,引种紫薇的花色、叶色能稳定遗传,是集观花、观叶于一体的优良的紫薇新品种。
The introduction experiments were carried out for purple-leaf crape myrtles Lagerstroemia indica from American for the purpose of introducing new varieties.By investigating biological characteristics and phenological phases,'Ebony Flame'、'Ebony Fire'、'Ebony Glow'、'Ebony Ivory'、Ebony Embers1 of new crape myrtles varieties were selected.Their flower colors are crimson or white or light pink,young leaves are red-purplish or gray-purple,mature leaves are black-purple and remains unchanged until leaf abscission.The results indicated that the flower and leaf colors can be genetically stable with ornamental of flowers and leaves.
