Abstract:
Using the seeds of Zinna elegans Jacq.as the test materials，the growth and development of plants induced by space flight in SP1 generation were investigated with the methods of biostatistics and molecular marker.The results showed that after experiencing space flight，the germination rate of Zinnia decreased slightly，and the infection rate of the black spot of Zinnia increased.In the space flight groups，a stable clover symbiotic variant H1-2 was found.The leaf size of the variant H1-2 was obviously less than that of the wild plant.Random amplified polymorphic DNA (RAPD) analysis showed that compared with the control plants，the genomic variation rate of the variant H1-2 was 13.4%.The studies of the mutagenic effects of space flight on Zinnia elegans Jacq.provided an experimental basis for space mutation breeding of ornamental plants.
