Abstract:
Taking dry seeds of Zinnia elegansJacq.as test material,they were irradiated by fast neutron with energy 14 MeV,the effect of different doses of fast neutrons radiation on seed germination and seedling growth of Zinnia elegans Jacq.were investigated.The results showed that compared with the c ontrol plants,Zinnia elegans Jacq.plants radiated by fast neutron had no significant differences on germination rate and seedling height.In the observation about plant traits,leafs and flowers of irradiated Zinnia elegans Jacq.plants occurred obvious variations,of which the variations on leafs could be repaired gradually in plant growth process,while that on flowers were basically stable.The disease survey results suggested that the infection rate of black spot disease of Zinnia elegans Jacq.plants radiated by fast neutron was obviously lower than control plants.In conclusion,neutron radiation technology was feasible for improvement of Zinnia elegans Jacq.varieties.The studies on the mutagenic effect of neutron radiation on biological traits of Zinnia elegans Jacq.provided an important reference and basis for flower breeding.
