湖南地区引种葡萄风信子的物候期及生长特性观察

为了丰富湖南省球根花卉种质资源,从荷兰引种‘流苏’、‘蔚蓝’、‘白美人’3个品种的葡萄风信子,对其在湖南地区的物候期、观赏特性和生长状况进行了观察。结果表明,3个品种的耐寒性均较强,‘蔚蓝’和‘白美人’的物候期早于‘流苏’;3个品种的单花序开花持续时间和群体开花持续约22~30 d,其中‘流苏’的开花时间最长,花序也最长,极具观赏价值。因此,认为葡萄风信子适合在湖南地区种植,可用于盆栽、花坛、花境、林下观花地被及岩石园绿化等。

Observation of Phenophase and Growth Characteristics on Different Grape Hyacinth Varieties in Hunan Area

In this paper, the phenological phase, ornamental characteristics and growth status of 3 grape hyacinth （Muscari botryoides） varieties in Hunan area were investigated and analyzed, the three varieties which imported from Holland are ＂fringe＂, ＂blue＂, ＂white beauty＂. The results showed that： 3 grape hyacinth varieties had strong cold tolerance, the phenological period of ＂fringe＂ was later than other two varieties. The single inflorescence flowering duration and groups of flowering duration of three varieties were about 22N30 d. The ＂fringe＂ had the longest inflorescence and flowering time, it had highly ornamental value. Therefore, grape hyacinths could be planted in Hunan area, they could be used in potting, flower beds, and border of wood and rock garden.
