摘要
简述了离子束生物技术的研究现状;明确提出了离子束生物技术在蔬菜遗传改良中值得注意的3大问题,即离子束介导技术比离子束诱变技术具有更大的潜在价值、遗传物质的供体与受体在亲缘关系上的远近在很大程度上决定着遗传改良的效果、建立高效的筛选体系将有助于提高离子束生物技术在蔬菜遗传改良中的效率。探讨了离子束生物技术在蔬菜遗传改良中的发展思路。
The research was on ion beam bio-technique and its three problems. The three problems were that the medium -technique of ion beam has larger potential value than the mutation-technique of ion beam, that the effects of genetic improvement on vegetable crops were mainly depended on the distance of the family relation between the supplier and the acceptor of the genetic materials, that the good system of identification and selection in the later generations promoted to gain higher efficiency of breeding on vegetable crops. The technical ideas, including the 1 technique basis in physics, the 2 developmental directions, the 3 effective changes, the 4 research hierarchies and the 5 biological characteristics worthy of notice, were particularly put forward and discussed.
