Wth 87-5 tomato for catchup as a treatment material and N+ ion as an inducing source

we carry out the experiments of stimulation and inducement. The dosage are implanted of 2×1016 N+/cm2、4×1016 N+/cm2、6×1016 N+/cm2 and 10×1016 N+/cm2 with low energy of 35keV in the pulse of 20、40、50 and 60 times respectively. As a result

growth rate of plant was low and time of growth fruit was ahead .When quality of fruit wasn't changed

number of per plant were increased and yield of parts of treatment types was remarkably improved.
