Table 1. O₂ concentration in water before and after different treatments.

The O₂ content in water(nmol ml⁻¹)	Day lily	Maize
Before treatment	245.0±0.58^a	245.0±0.5^a
After 36 h of DST	49.1±0.71^b	38.5±1.29^b
After 36 h of DST+Air	243.0±0.15^a	225.7±1.00^a

Changes in the O₂ concentration of the water before and after pumping air in during dark-submergence treatment (DST). Means ± SE of three replicates are presented. Different letters indicate significant differences between treatments, P<0.05. Differences were analyzed by least significant difference (LSD).
