e0“The results showed that compared to CF, the chlorophyll a content of rice leaves, the plant height of rice, leaves area, per panicle total grain and weight decreased under the treatment of high ozone concentration (200 nL· L-1), 47.9%, 17.8%, 31.6%, 45.7% and 42.9% respectively”
e1“But with exogenous ascorbic acid spraying, there was a rising trend in the chlorophyll a content of rice leaves, the plant height of rice , leaves area , per panicle total grain and weight, 11.6%,7.7%,17.4%,5.6%, 11.1% respectively”
