The seed of processing tomato “87-5” (Lycopersicon esculentum Mill) were implanted by the low energy nitrogen ion (N+) with 6 different doses. The rate of emergence was little reduced in M1 generation

but the fruiting number per plant was increased and its maturing earlier 20 days than the control. The precocity

disease resistance and stronger growth vigor were shown in M2 generation. Experimental results of two years showed that

according to synthetic analysis in factors such as precocity

disease resistance

high yield and quality

the N+ dose of 6×1016cm-2 (60 times of pulse) for tomato seed “87-5” had been proved to have notable biological effects on M1 and M2 generation. The seed of eggplant “Wuyeqie” (Solanum melongena L.) was also implanted by the low energy nitrogen ion (N+) with 2 different doses. Multi-vertical channel fruits were obtained in variable M1 generation

which liked the pomelo without peel. The seed of these variable eggplants was taken and planted in the next year. The meaningful variable fruits

the characters of disease-resistance

purple-peel

small-navel

lantern-form

large-scale

etc. were obtained in beneficial M2 generation. The biggest single-fruit weight reached 1.53kg

providing valuable germplasm resource for breeding.
