The effects of postharvest oxalic acid (OA) treatment on ethylene production, fruit quality, bioactive compounds and antioxidant activity of peach fruit, were examined. Fruits were treated with oxalic acid immediately after harvest and stored at 1° C and 90% relative humidity for 28 days. The oxalic acid treated peach fruit exhibited significantly lower levels of ethylene production, pH, total ...

Because of the primary aminic character of asulam, it is readily labelled with fluorescamine. A study of the variables affecting the derivatization reaction has been made. Two analytical approaches, that is, direct, synchronous spectrofluorimetry have been tested, and they both show good analytical performances. The linear dynamic range of the synchronous approach is 0.043-0.214 mug/ml and the ...
