Preliminary study on the effect of UV B treatment on enzyme activity and seed setting in rice
Year: 2009
Type: article
Abstract: UV B was treated on autumn rice Texianzhan 13 planted in the field from ear differentiation stageⅠto stage Ⅲ.Several enzyme activities in rice leaves were detected.The results showed that IAA oxidase activity in leaves was not obviously changed at 4th day after UV B treatment,but increased at 11th day.The increase of IAA oxidase activity had relation to UV B treatment hours per day.Peroxidase and Poliphenol oxidase were not affected by UV B treatment.The grains per panicle and the seed setting percentage were investigated.The grains per panicle was not changed by UV B treatment.The seed setting percentage was decreased by UV B treatment.The decrease of seed setting percentage also had relation to UV B treatment hours per day.
