摘　　要：我们利用氦-氖激光作为光源,对番茄两个品种的种子分别进行了不同激光功率密度、不同时间,多个组合的处理,观察用激光辐射后的番茄种子发芽情况和幼苗的长势。试验结果表明:功率密度在0.016—0.024瓦/厘米~2,We have irradiated two tomato varieties with He-Ne laser in different power den-sities,different irradiating times that divided them into many test groups.From the observingof the seeds germination rate and the seedling growth potential,we found that the power den-sity was 0.016-0.024 W/cm^2,then the seeds germination and seedling growth were greatly pro-moted.
