Select buckwheat seeds with full particles and uniform size, soak them in 0.5% KMnO4 for 20 min, clean them with distilled water, transfer them to the white porcelain plate after soaking for 24 h, spread white gauze to keep moisture, and accelerate germination in the dark incubator for 24 h. After the seeds are exposed to white, the radicle is inserted into the pure agar medium, 15 seeds in each bottle, the lid is screwed tightly, and the culture is inverted in the dark incubator at 25 ℃ [19]. Materials were randomly divided into two groups:<br>
