摘　　要：免疫诱抗剂ZNC是一种宛氏拟青霉菌的乙醇提取物,具有促进植物生长、提高植物产量和抗逆性的能力。于水稻苗期和孕穗期喷施不同剂量的ZNC,试验了其对水稻增产抗逆的效果。结果表明,喷施不同浓度ZNC均可以促进水稻生长,其中以浓度为10 ng/mL的处理效果最显著,芽长和根长较对照(不施ZNC)分别增加17.2%和33.7%;在200 ng/mL浓度处理下,成株期水稻根系干物质积累量最高,为3.14 g,较对照增加46.7%;浓度为200 ng/mL处理增产效果最好,实收产量达658.74 kg/667 m^(2),较对照增产8.45%。在10~200 ng/mL浓度范围内,喷施ZNC均可提高植株对水稻纹枯病的抗性,且以200 ng/mL浓度处理表现最佳。Immune inducer ZNC is an ethanolic extract of Paecilomyces variotii,which has the ability to promote plant growth and increase plant yield and stress resistance.Different doses of ZNC were applied at the seedling and booting stages of rice,their effects on rice yield and stress resistance were studied.The results showed that spraying ZNC could promote the growth of rice.Among them,the treatment with a concentration of 10 ng/mL had the most significant effect to the shoot length and root length by 17.2% and 33.7% increasement,respectively,compared with the control(without ZNC).At the concentration of 200 ng/mL,the dry matter accumulation of rice roots was the highest at 3.14 g,which was an increase of 46.7% compared with the control.The treatment with a concentration of 200 ng/mL had the best yield increase effect,the actual yield reached 658.74 kg/667 m^(2),which was an increase of 8.45% compared to the control.In the concentration range of 10~200 ng/mL,spraying ZNC could improve the resistance of rice to rice sheath blight,and the treatment with a concentration of 200 ng/mL performed best.
