摘要
以锦屏藤(Cissus sicyoides‘Ovata’)枝条为插穗就其水插生根特点进行了试验研究。结果表明:锦屏藤水插4～6d即萌发出不定根;以木质化老枝插穗生根数最多,半木质化中等成熟枝次之,未木质化嫩枝生根最少;水插生根最适宜的环境温度为25°C;水插前用15mg/L吲哚丁酸(IBA)浸渍基部48h,可显著促进插穗水插生根。
Rooting of Cissus sicyoides ＇Ovata＇ cuttings in water was investigated. It was found that Cissus sicyoides ＇Ovata＇ cuttings could form adventitious roots after placed in water for only 4-6 d. Additionally, the number of adventitious roots was remarkably affected by the lignified degree of cuttings, namely, the more lignified cuttings the more adventitious roots. The optimum environmental temperature for moderately lignified cuttings to form adventitious roots was 25℃. Pretreatment with 15 mg/L indolebutyric acid （IBA） for 48 h could further enhance the growth of adventitious roots.
