摘　　要：采用日本引进的ESS-010-03型电子直线加速器辐照装置处理番茄品种‘1479’种子,对其萌发和M1代植株生长进行观测,通过室内发芽试验和田间栽培统计种子发芽、出苗和植株生长发育情况。结果表明,电子加速器处理种子后对番茄种子萌发和M1代植株生长发育产生显著影响。达到400 Gy的电子束处理显著降低了种子的萌发水平和幼苗的存活率。辐照组植株生长缓慢,株高和茎粗显著低于对照组;电子加速器处理显著增加了幼苗的侧枝数、侧根数和生物量的积累,降低了根冠比;且对番茄生殖生长产生显著影响,增加了花的败育和畸形果的数量。Tomato seeds of cultivar 1479 were irradiated by electron accelerator ESS-010-03 that imported from Japan.The seed germination,seedling emergence,seedling growth conditions and plant growth and development were observed by germination test and field cultivation.We found that electron accelerator treatment had a significant effect on seed germination and growth and development of M1 generation plants.The levels of seed germination and seedling survival rate significantly decreased in the electron beam treatment with the dose of 400 Gy.In the electron beam treatment group,plants grew slowly,height and stem diameter of seedling were lower than the control group.The biomass accumulation of the seedling body increased and root/shoot ratio decreased in the electron accelerator treatment.Compared with the control group,the treatment groups had much more lateral branches and lateral roots.Moreover,electron accelerator showed a significant impact on the reproduction growth of tomato plants.
