Salinity is one of the most important abiotic stresses that can limit the growth and yield of crops, but application of bio fertilizers and nano silicon can moderate the effects of salinity. So, in order to study the effects of salinity, bio fertilizers and nano silicon on chlorophyll content and grain filling components of triticale, an experiment was conducted as factorial based on randomized complete block design with three replications in greenhouse research of Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabili during 2021. Factors experiment were included salinity levels (no application of salinity as control, salinity of 30 and 60 mM by NaCl), application of bio fertilizers (no application as control, application of vermicompost, mycorrhiza, both application of vermicompost and mycorrhiza), and nano silicon foliar application (foliar application with water as a control, foliar application 30 and 60 mg.L-1 nano silicon). The results showed that both application of vermicompost, mycorrhiza and foliar application of 60 mg.L-1 nano silicon under no salinity conditions increased root weight and volume (34.82 and 12.92%, respectively), chlorophyll a, b, total chlorophyll and carotenoids content (80.22, 90.32, 88.82 and 80.96%, respectively) and leaf area index (132.96%) compared to no application of bio fertilizers and nano silicon under 60 mM salinity conditions. Also, both application of vermicompost, mycorrhiza and foliar application of 60 mg.L-1 nano silicon under no salinity conditions increased maximum of grain weight, grain filling period and effective grain filling period (40.07, 25.69 and 44.93% respectively) and grain yield (88.88%) compared to no application of bio fertilizers and nano silicon under 60 mM salinity conditions. It seems that the application of bio fertilizers and nano silicon can increase grain yield of triticale under salinity conditions due to improve leaf area index, root weight and volume, chlorophyll content and grain filling components. |
