- 摘要:
- 以大叶黄杨白粉病分生孢子为研究对象，研究了6种植物油乳油对分生孢子的染色效果，并测定了其对分生孢子悬浮液电导率的影响。结果表明：6种植物油乳油致使白粉病分生孢子细胞壁凹陷、畸形，对细胞壁有破坏作用，使得孢子内部细胞质渗漏，孢子悬浮液电导率值随着植物油乳油处理浓度的增大而增大,3.30 mL/L植物油乳油的稀释浓度是一个临界点，再提高植物油用量其电导率变化不明显。因此，在生产上建议使用3.30 mL/L的用量防治白粉病经济可行。
- Abstract:
- Taking the spores of Buxus megistophylla powdery mildew as object,the dyeing effect of 6 species of vegetable oil EC on spores were studied,and the effect on conductivity of spore suspension was determined.The results showed that 6 species of vegetable oil EC caused powdery mildew cell wall depression,deformities,with damage effect on the cell wall,making the internal cytoplasm flow.Conductivity increased with the concentration of spore suspension increased.3.30 mL/L of vegetable oil was a critical point.The results indicated that the optimum concentration was 3.30 mL/L on powdery mildew fungi.
