Evaluation of the Effect of Low-Temperature Plasma Treatment on Seed Germination of Long-Term Stored Genetic Resources

Popis výsledku v původním jazyce

Low-temperature plasma (LTP) is currently one of the non-invasive and environmentally friendly methods of seed treatment and is massively tested on various types of crops. For the needs of gene banks, the use of LTP technology represents the treatment of seeds before sowing to improve the germination and emergence of long-term stored seed samples. Seeds of four genotypes of wheat, oats, flax, and rapeseed stored in the gene bank for 1, 10, and 20 years were plasma treated for 20, 25, and 30 min. Standard germination parameters (SG3, SG7, GR, MGT, and GI), as well as predictive models, were used to evaluate the effect of plasma treatment on seeds, and the effect on seed metabolism was assessed by superoxide dismutase (SOD) activity. The plasma treatment had different effects on germination and on the enzymatic activity of the tested species, and the result was influenced by both the duration of the treatment and the crop species/genotype. The plasma treatment has a positive effect on germination parameters in flax and rapeseed; in some variants, as in wheat, oats generally reacted negatively. SOD activity was variable in wheat, while higher activity with increasing treatment time was found in other crops. The results of this first study focused on long-term stored seeds and showed the potential of plasma treatment of seeds of plant genetic resources, the possibility of stimulating the germination of stored PGRs, and the need to optimize treatment conditions for individual genotypes.
