近十儿年来,国内外农林业应用中子辐射育种已取得了较好的成绩,中子辐射技术越来越多地、比较广泛地应用于国民经济生产建设上。我国近几年来也开展了中子辐射技术应用的研究。如辽宁省的柞蚕所用适宜通量照射蚕卵,增产幅度为5—87％,平均为33.5％。据有关资料介绍,以瓜类蔬菜增产效果最好,经济作物次之,禾谷类较差,而木本植物的种子辐射敏感性的研究报导却很少。樟子松是我国东北地区有发展前途的造林树种之一,但种子来源不足,影响育苗造林事业的发展。为了促进提高现有种子的发芽力和利用率,于1981年结合樟子松种子生活力(以
In recent ten years, the application of neutron radiation breeding in agriculture and forestry has made good achievements at home and abroad. More and more, neutron radiation technology has been applied to the construction of national economy more extensively. In recent years, China has also carried out research on the application of neutron radiation technology. For example, the appropriate flux for tussah in Liaoning province irradiated silkworm eggs, with a yield increase of 5-87% and an average of 33.5%. According to the relevant information, melons and vegetables produce the best yield, followed by cash crops, and cereals are poor, while the researches on the radiation sensitivity of woody plants are seldom reported. Pinus sylvestris var. Mongolica is one of the afforestation tree species in northeast China with a promising future, but the source of seeds is not enough, which affects the development of nursery and forestry afforestation. In order to promote the germination and utilization of existing seeds, in 1981 combined with Pinus sylvestris seed viability
