Abstract:

Acid rain is considered to be the top ten environment concerns in the world In a field experiment, soybean ( Glycine max L ) cultivar Xuzhou 18 was subjected to simulated acid rain (AR, pH3-5), followed by foliar application of APK 9 consisting of ascorbic acid (AsA) and polyaspartic acid The alleviative effect of APK 9 on AR stress in soybean plants was then investigated The results showed that AR obviously depressed growth after flowering stage and finally reduced soybean yield Chlorophyll content, nitrogen accumulation, phosphorus accumulation, AsA content, and antioxidative enzyme activities in AR stressed seedlings were enhanced, while malonyldialdehyde (MDA) content was repressed by application of APK 9 in flowering stage and podding stage However, chlorophyll content in leaf, biomass and yield reduced while MDA content increased when APK 9 was sprayed in seedlings stage and seed filling stage Thus, AR stress on soybean plants was effectively alleviated by foliar application of APK 9 in flowering stage and podding stage and the alleviation effect could be depressed by earlier or later application of APK 9 Here, spraying APK 9 in flowering stage had the greatest effect on AR stressed plants
