气雾栽培条件下4种芳香植物扦插生根表现

Rooting Performance of Four Aromatic Plants Cutting under the Aeroponic Cultivation Condition

在气雾栽培条件下,对排草香(Anisochilus carnosus),碰碰香(Plectranthus hadiensis var.tomentosus),广藿香(Pogostemon cablin)和紫苏(Perilla frutescens)4种芳香植物开展扦插繁殖试验,对不同插穗具节数及叶片数进行对比,结果表明,碰碰香扦插后最早3 d即可生根,广藿香最迟15 d可生根;在插穗具3节及2片叶的条件下,排草香和碰碰香可达到90%以上的生根率,根系长度和数量均较高;在一定范围内,4种芳香植物插穗带叶片数越多,插穗平均根数越多,平均根长越长;插穗具节增多,插穗的生根率、平均根长、平均根数均有一定的增长。

Anisochilus carnosus, Plectranthus hadiensis var. tomentosus, Pogostemon cablin and Perilla frutescens were used to carry out the cutting propagation test under the aeroponic cultivation condition. The results showed that P. hadiensis var. tomentosus took root after 3 days, and P. cablin need 15 days. The rooting rate of A. carnosus and P. hadiensis var. tomentosus were over 90% while their cuttings with 3 nodes and 2 leaves. The root number and length had positive correlation with the nodes and leaves of cutting within limits.
