Abstract:

Contamination was a serious problem in seed germination and tissue culture of safflower (Carthamus tinctorius L.). In our study, seeds were disinfected in order to reduce the contamination rate.Three factors including soaking time, disinfecting agents and disinfecting time were used for L9(3 4) orthogonal experiment. Results were comprehensively evaluated by using the weighted scoring method based on indexes such as germination rate, germination vigor and contamination rate. Orthogonal test showed that the disinfecting agent was the most important factor affecting the seeds germination. Among various treatments, seeds soaked in sterile water for 12h followed by the 2% sodium hypochlorite (NaClO) for 10min was the best disinfecting method in safflower seeds which yield a contamination rate of 8% and a germination rate of 90.67%. In addition, 16S rDNA (GenBank Accession No. MH190221) of a bacterium was isolated from seeds and purified after disinfection which was amplified by PCR. BLAST results showed that it belonged to Bacillus aryabhatti which was most likely to be entophytes in safflower seeds. The results of this study provided an important basis for obtaining well-grown aseptic seedlings, tissue culture as well as genetic transformation.

Key words: Carthamus tinctorius L., Seed disinfection, Seed germination rate, Orthogonal experiment, Bacteria
