为查明辐射播前处理树木种子的效应,探讨生产实践中应用的可能性,我们于1963—1965年进行了用低剂量γ射线处理树木种子的试验,现简介于下: 一、试验材料和方法供试树种有侧柏、落叶松、红松、油松、桧柏、紫穗槐、白蜡、核桃、桑、楝、泡桐、悬铃木、刺槐、椴、榆等针、阔叶树种子。种子均为生产性的(说明者除外),含水量为7—8%。辐射处理剂量率1964年为180伦琴/分, In order to find out the effect of seed treatment before radiation sowing and to explore the possibility of application in production practice, we conducted the experiment of treating tree seed with low-dose γ-ray from 1963 to 1965. The following is a brief introduction: Methods The test species were arborvitae, larch, red pine, Pinus tabulaeformis, juniper cypress, Amorpha fruticosa, white wax, walnut, mulberry, neem, paulownia, Platanus, acacia, linden, elm needle, broadleaf tree seed. Seeds are productive (except as noted) and have a moisture content of 7-8%. The radiation dose rate in 1964 was 180 Roentgen per minute,
