Abstract
Field cultivation experiments on white sesame (Sesamum indicum L.) seeds implanted with low-energy C ion showed that different dosages of C ion implantation produce different biological effects. Sesame plants in 6 different dosage groups with C ion density respectively at 1 × 1011, 1 × 1012, 1 × 1015, 5 × 1015, 1 × 1016, 5 × 1016 ion/cm2 were superior to the control group in plant height, leaf number, stalk diameter and leaf size. Further, sesame plants in these groups flower and seed earlier than those in the control group, and single plant yield also increased. Of all the groups, the 5 × 1015 ion/cm2 dosage group yielded the best effect, whereas the 1 × 1017/cm2 dosage group showed an evident inhibitory effect of ion implantation on the germination and growth of the sesame seeds.
