摘要： BackgroundAlthough matrine is widely used, its absorption and transport mechanisms in crops remain unexplored. In this study, three methods including foliar application, hydroponics and seed immersion were used to investigate whether matrine molecules could enter into plants through different channels, and to further resolve its transport characteristics. The systemic activity of matrine also was evaluated. ResultMatrine was quickly absorbed and transported downwards after the leaves of wheat or peppers were treated, and also accumulated and transmitted upwards by roots. It was not only absorbed by seeds, but also appeared continuously in young roots and leaves in both plants for nearly 20 days. There were some differences in the uptake and conduction of matrine between pepper and wheat: matrine concentrated in pepper upper leaves with less delivered downwards to roots than in wheat, and also transduction of matrine in pepper lower leaves upwards to upper leaves was less than in wheat. Matrine had systemic activity, with LC50 of 361.99 and 904.24 mu g center dot mL(-1) against Rhopalosiphum padib on wheat and Myzus persicae (Sulzer) on pepper plants at 48 h, separately. ConclusionMatrine can be absorbed by the roots, seeds and leaves of plants, and transmitted bidirectionally to any organs, presenting satisfactory systemic poisoning activity against aphids. It is of great significance to develop new formulation products of matrine and promote its commercialized value. (c) 2023 Society of Chemical Industry.
