Evaluation the impact of different polyamines on some nutritional composition of basil (Ocimum basilicum L.) hydroponic culture conditions

This research was carried out in Pakdasht private greenhouse, to evaluate the effect of putrescine, spermine, and spermidine on the quantity of Basil under conditions of salt stress as a factorial experiment in a completely randomized block design with three replications in 2016-2017. The treatments included the application of putrescine, spermine, and spermidine at levels 4 (0, 50, 100, and 150 mg/l), salinity stress at four levels (0, 50, 100, and 150 mM), and control treatment (distill water). The results showed that the interaction effects between polyamines, salinity, and concentration on Potassium, Phosphorus, Calcium, Manganese, Manganese Zinc, Iron, Cupper content, was statistically significant at 1% level. K, P, Ca, Mg, Mn, Zn, Fe, Cu content raised in all polyamine treatments.  Interaction and simultaneous exposure of 150 mg/l spermidine and low salinity had a positive effect on all the studied plant traces. In addition, the findings indicated that the concentration of 150 mM sodium chloride solution reduced the mentioned traits. However, spermidine improved this condition and symptoms of stress and damages were less observed in spermidine-treated plants. Therefore, it seems that the enhancement synthesis of compounds in plant tissues acts as a health activator in the human body.
