Abstract

Abstract: 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．

Key words: electron accelerator, germination, growth and development, malformation
