植物免疫诱抗剂对玉米耐盐性及产量的影响
Effects of Plant Immune Inducer on the Salt Tolerance and Yield of Maize
摘要
Abstract
In order to explore the effect of plant immune inducer on salt tolerance and yield of maize,an experiment was conducted in Yantai,Shandong Province in 2022 with ZNC as the experimental material.The seed germination rate,root growth and yield of maize treated with different concentrations of Zhinengcong(ZNC)were compared and analyzed under salt stress.The results showed that in 8 and 10 g/L NaCl salt solution,the germination rate of maize seeds was 27.5%and 17.5%respectively,and the length of main root was 19.8 and 13.0 mm,respectively,which was significantly lower than its germination rate(52.5%)and main root length(55.9 mm)in aqueous solution,indicating that salt solution could inhibit maize germination and root growth.After soaking seeds with 20 ng/mL ZNC,the germination rates of maize seeds under 8 and 10 g/L NaCl salt solution stress were 38.0%and 25.0%respectively,and the length of main root was 24.5 and 15.1 mm,respectively,indicating that seed soaking with ZNC could alleviate the inhibitory effect of salt solution on maize seed germination and root growth.By using intelligent seed dressing combined with water spray treatment during the growing pe-riod of corn,the yield of corn increased by 5.02%.According to the comprehensive analysis,under the condition of salt stress,the application of ZNC can promote the growth of maize and increase the yield.关键词
