Effects of humic acid on changes in nutrient concentrations of leaf, root and stem nutrients of Satureja khuzestanica under salinity stress
Authors
Abstract:
To investigate the influence of humic acid on the amount of absorption and allocation of elements to different parts of Satureja khuzestanica under salinity stress conditions, a greenhouse experiment was done as factorial based on a randomized complete block design in four replications. Factors included humic acid (zero, 10, 20, 30 and 40 mg kg-1 soil), and salinity stress (zero, 25, 50, 75 and 100 mM NaCl). Resalts indicated that effect humic acid salinity, and their interaction were significant on measured characteristics except nitrogen of stem and nitrogen of leave. Results showed comparatively among organs (root, stem and leave), the highest amount of sodium, potassium, phosphorus, zinc and nitrogen (5064, 9000, 13, 19.92 and 3.91 mg kg-1 of dry weight) were observed in leaves in the S1H5, S2H2, S1H4, S1H5 treatments, respectively. Among different organs, maximum iron content (759.9 mg kg-1 of dry weight) was observed in root under S2H1. Salinity over 25 mM and also decrease in humic resulted in decreased nutrient contents, except sodium. According to results, humic acid can be used in high amounts such as 40 and 60 mg kg-1 for decreasing influences of salinity stress.
