The objective of this research was to approach the effect of seed moisture content on welsh onion seed longevity. Welsh onion seeds with 5％ or 14％ moisture content were stored for five months at 8℃ or at room temperature [25±5℃/15±5℃]. Germinationof seeds stored in a paper package at room temperature was significantly lower around 80％ than that of seeds stored at 8℃. For seeds with 5％ moisture content stored at 8℃, germination was greater than 80％ after stored for 5 months, CO2 production was 210 μ1/ g FW/hr , and soluble sugar content were 60 mg/g DW. For three seeds, total peroxide and malondialdehyde (MDA) content were 60 mg/g DW.For three seeds, total peroxide and malondialdehyde (MDA) content were 10％ lower, superoxide dismutase (SOD) activity was 13％ higher, and catalase (CAT) activity was 25％ higher than in seeds stored at 8％ with 14％ moisture content.
