摘　　要：采用离体叶片与玻璃纸接种,测定多效唑对杧果炭疽病菌Colletotrichum gloeosporioides的调控作用。结果表明,多效唑700、800、900、1 000mg/L药液都能一定程度影响炭疽病菌在杧果离体叶片上的扩展,多效唑800mg/L能明显延缓炭疽病病程。在玻璃纸上多效唑800mg/L能够抑制杧果炭疽菌菌丝生长,致使分生孢子畸形,不形成附着胞;在离体叶片病菌分生孢子形态正常,产生附着胞。Effect of paclobutrazol on control of mango anthracnose was investigated by detached leaf method and inoculation with cellophane paper.The result indicated that 700mg/L、800mg/L、900 mg/L、1 000mg/L paclobutrazol showed some effect on controlling the development of disease on the detached leaf. Mango anthracnose significantly reduced after the spray of 800 mg/L paclobutrazol to the detached leaf.Applying 800 mg/L Paclobutrazol on cellophane paper could inhibit the growth of hypha,cause spores to become abnormal and not produce appressorium.The spore showed normal morphology and can germinate appressorium on detached leaves treated with 800mg/L paclobutrazol.
