ABSTRACT
The combined effects of hydropriming and plasma-activated solution (PAS) were investigated on the seed viability, the contamination of microorganisms, and seed surface differentiation, and morphology of black soybean seed (Glycine max L. Merr cv. Sukhothai 3). The studies had 3 steps: i) to find the proper time of seed hydropriming through seed imbibition rate, ii) to measure the properties of PAS-H2O2 treatment, and iii) to investigate combined effects between hydropriming and PAS-H2O2 treatment on soybean seed quality. The result showed that the optimum time of seed hydropriming was 5 hrs. of imbibition. It gave the highest seed quality when compared to the control treatments. The properties of ORP, EC, and dissolved oxygen values were decreased but pH and temperature increased as the time extended. The combined effects of both techniques by pre-treating primed seeds with PAS at different times of plasma discharge for seed quality were determined. The results indicated that the combining procedures via 5 hrs. of hydropriming followed by 3 and 5 min of PAS-0.05% H2O2 gave the best seed germination (92/93 %), seed vigor (88/89 %), and seedling dry weight (16.6/15.1 g/plant). However, prime seeds were treated with PAS-H2O2 for 5 min expressed lower in microbial (17.7%) than other treatments, and pathogens could be controlled more than the use of single treatment. The changes of seed coat surface expansion and seed pores features occurred in plasma seeds lonely and in association with hydropriming and were higher than those of primed seeds only. In summary, the use of hydropriming and PAS-H2O2 treatment could be applied as a pre-sowing treatment to enhance the seed quality of black soybeans.
