用 35Kev的 N+离子束注入茄子、蕃茄、辣椒等种子 ,进行诱变处理。通过田间种植对照分析 ,茄子比对照增产 2 5.0 %～ 57.9% ,发病率仅在 1 .89%～ 4.62 % ,变异果大 ,果脐呈带状、拉长 ,变异明显。离子束注入的加工蕃茄比对照早熟 2 0天 ,产量可提高 2 2 .4% ,蕃茄红素等品质因素经检测都有提高 ,当代效应十分明显。辣椒经离子束注入后 ,平均出苗率比对照提高 8.0 % ,显著提高了疫霉病的抗病性 ,死病率仅 38.6% ,比对照死病率 89.7%下降了 51 .1 % ,有望解决多年来一直困扰生产的辣椒抗病性难题
35Kev N + ion beam injected eggplant, tomatoes, peppers and other seeds, mutagenic treatment. Compared with the control, the yield of Eggplant increased by 5.05% ~ 57.9% and the incidence rate was only 1.89% ~ 4.62%. The tomato injected with ion beam was 20 days earlier than the control and the yield could be increased by 22.4%. Quality factors such as lycopene increased after detection, and the contemporary effect was very obvious. After the ion beam injection, the average germination rate increased by 8.0% compared with the control, significantly increased the disease resistance of Phytophthora capsici, the death rate was only 38.6%, 51.1% lower than the control mortality rate of 89.7%, is expected to be resolved Over the years has been troubling the production of pepper disease resistance problems
