摘　　要：.激光与DNA作用将产生非线性共振、混沌、随机共振和随机混沌等非线性现象 ,使DNA变异、断裂 .因此激光辐照DNA导入番茄 ,有益于供体的一些显性基因性状在受体后代得到表达 ,品质得到改善 .对过氧化物酶同工酶的分析表明 ,受体后代与受体对照的同工酶图谱差异较大而与供体对照的同工酶图谱差异较小 ,这与它们在叶形与生长型表达上的差异是吻合的 .这些表明了激光辐照DNA已经导入受体 ,并得到整合表达 .Some nonlinear phenomena of nonlinear resonance, chaos, stochastic resonance and stochastic chaos occur in the laser-DNA interactive system, which make DNA mutated and broken up. The laser-radiated exogenous DNA was introduced into the tomato. It is beneficial to the expression of some characters of dominant genes of the donor and the improvement of the descendents qualities of receptors. The peroxidase isoenzyme of the donor, the receptor, and their descendents were analyzed. Our result shows that the peroxidase isoenzyme zymograms of most descendents are very similar to the donor but rather different from the recepor. The similarity of isoenzyme zymograms between descendents and donor, and the expression of external characters of donor in descendents indicate that the exogenous DNA has been saccessfals introduced into the receptor with the expression of exogenous DNA in descendents.
