Effects of salicylic acid and silica on the nutrients absorption in the plant radishes under salinity stress
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 10
Abstract
To find out effects of salicylic acid and silica on the nutrients absorption in the plant radishes under salinity was conducted a research in greenhouse of Islamic Azad University of Damghan, in 2013 .First seeds of radishes were sterilized with 0.1% sodium hypochlorite for 4 hours and rinsed repeatedly with distilled water. After sterilization, the seeds were planted in pots containing 4 kg amended soil. Seeds were irrigated after the planting with distilled water. After 3 weeks salicylic acid and silica treatments were added to pots. Saline solution as irrigation water were prepared by adding sodium chloride (NaCl). Pots were maintained under controlled condition at temperature of 25 Celsius and relative humidity of 40% in greenhouse. In the end were analyzed Fe and Mn of shoot and root parts of plant .The analysis of variance (ANOVA) was done using Duncan’s method. A factorial experiment in greenhouse was conducted in the base of Randomized Complete Design (RCD) with three replications. The study was designed as two factors , included 9 treatments with three replications and the first factor was three Levels of silica (si) with three concentrations as following: Si0 =0 (control): (Si1)=1.5 . : ( Si2) =3Mm and SA as following: (SA0) = 0 Mm , (SA1 )= 0.5 Mm,the (SA2) = 1.5 Mm . Analysis of variance indicated significant differences by salicylic acid and silica on shoot and root absorption of nutrients by radish in the all levels by compared with control (Table 3). The interaction between the salicylic acid concentrations and kind of silica gave significant differences in all of the study parameters (except Mn in silica and (silica * Salicylic acid) treatments of root).
