材料和方法1.植物材料用花色火红的月季栽培品种 Mercedes 的枝条作试材,进行三种不同处理。(1)用1—13kR(0.45kR/min,下同)~(60)Co Υ射线处理带有一叶一芽的枝条,每一剂量处理120枝。辐照处理后,在喷雾条件下,将枝条扦插在细砾和泥炭藓(1:1)的混合物中。5—7周后,将生根插条移入聚乙烯塑料大棚温室定植。(2)用4—8 kR~(60)Co Υ射线处理带有三个芽和一片顶叶的枝条,每一剂量处理36
MATERIALS AND METHODS 1. Plant material Three different treatments were carried out with the Mercedes-colored shoots of the rose-colored rose cultivars. (1) Branches with one leaf and one bud were treated with 1 to 13 kR (0.45 kR / min, the same below) to (60) Co γ rays for 120 treatments per dose. After irradiation, the shoots were cut in a mixture of fine gravel and peat moss (1: 1) under spray conditions. After 5-7 weeks, the rooting cuttings were moved into a polyethylene plastic greenhouse greenhouse for colonization. (2) Branches with three shoots and a parietal lobe were treated with 4-8 kR ~ (60) Co Υ rays, and each dose of 36
