The absorption, transport, and subcellular distribution of strobilurin fungicides (azoxystrobin, pyraclostrobin, and trifloxystrobin) have been studied in cucumbers. Under hydroponic laboratory conditions, pyraclostrobin and trifloxystrobin mainly accumulated in cucumber roots whereas azoxystrobin accumulated in cucumber leaves. In the subcellular distribution experiment, azoxystrobin mainly accumulated as a soluble component. Pyraclostrobin and trifloxystrobin accumulated more in the organelles and cell walls. Azoxystrobin and pyraclostrobin enter the root primarily through the apoplast pathway, whereas trifloxystrobin enters the root through the symplastic pathway. Azoxystrobin can be transported in cucumber through anion and cation channels, whereas pyraclostrobin and trifloxystrobin can be transported only through anion channels. This study has great significance in evaluating environmental risks and food safety.

黄瓜 (Cucumis sativa L.) 中甲氧基丙烯酸酯类杀菌剂的吸收、易位和亚细胞分布


已经在黄瓜中研究了甲氧基丙烯酸酯类杀菌剂（嘧菌酯、唑菌胺酯和肟菌酯）的吸收、转运和亚细胞分布。在水培实验室条件下，唑菌胺酯和肟菌酯主要积累在黄瓜根部，而嘧菌酯主要积累在黄瓜叶部。在亚细胞分布实验中，嘧菌酯主要以可溶性成分的形式积累。唑菌胺酯和肟菌酯在细胞器和细胞壁中积累较多。嘧菌酯和唑菌胺酯主要通过质外体途径进入根，而肟菌酯通过共质体途径进入根。嘧菌酯可以通过阴离子和阳离子通道在黄瓜中转运，而唑菌胺酯和肟菌酯只能通过阴离子通道转运。本研究对于评估环境风险和食品安全具有重要意义。
