  1. Values are means ± standard deviation, *Indicate significant difference at p < 0.05, respectively, between treatments and control. Control - no NZVC treatment, using distilled water; CoVN - 1, 2 and CoUSA - 1, 2: Seeds were treated with 0.17 and 16.7 mg/kg seeds of Vietnamese and USA NZVCs, respectively
