摘要
利用生物测定技术和高效液相色谱法研究了氟吗啉在黄瓜植株体内的吸收、传导和分布行为及其机制.结果表明,氟吗啉能被黄瓜植株被动吸收,并通过木质部在体内传导和分布.
Uptake, translocation, and distribution behavior of flumorph in cucumber seedling were determined by biological test and the high performance liquid chromatography （HPLC） method. The results showed that flumorph was a systemic fungicide and translocated upwards readily in trachea of the xylem with transpiration but not in the phloem, so it was easily accumulated in leaves. Flumorph also showed a translaminar activity and redistribution activity in intact plants, but can not translocate from one leaf to another in either acropetal or basipetal direction. For these reasones, flumorph can protect whole plant after being applied in soil, but be failed to protect new leaves after foliar application. CCCP, temperature, the properties of amino acid and sucrose, as well as the pH values of solvents had no significant affect on the intake of flumorph by cucumber, indicating that it tended to uptake and transport flumorph passively.
