Abstract

2,4-D in plants very rapidly undergoes various transformations and its predominant metabolic pathways and rates vary with different plant species. In bean and soybean plants major 2,4-D metabolites are 4-O-beta-D-glucosides of 4-hydroxy-2,5-dichloro- and 4-hydroxy-2,3-dichloro-phenoxy-acetic acids; in addition, considerable amounts of N-(2,4-dichlorophenoxyacetyl)-L-aspartic and N-(2,4-dichlorophenoxyacetyl)-L-glutamic acids are accumulating in them. Among 2,4-D metabolites in cereals there prevailed 1-O-(2,4-dichlorophenoxyacetyl)-beta-D-glucose while the glycoside of 2,4-dichlorophenol prevailed in strawberry plants.

摘要

植物中的2,4-滴会迅速经历各种转化，其主要代谢途径和速率因植物种类而异。在豆类和大豆植物中，主要的2,4-滴代谢物是4-羟基-2,5-二氯-和4-羟基-2,3-二氯苯氧基乙酸的4-O-β-D-葡萄糖苷；此外，大量的N-(2,4-二氯苯氧基乙酰基)-L-天冬氨酸和N-(2,4-二氯苯氧基乙酰基)-L-谷氨酸在其中积累。在谷类作物的2,4-滴代谢物中，1-O-(2,4-二氯苯氧基乙酰基)-β-D-葡萄糖占主导，而在草莓植物中，2,4-二氯苯酚的糖苷占主导。
