Abstract
In order to investigate the effect of mixing sea and underground water on the morphological and biochemical properties of the purslane medicinal plant, an experiment was conducted in the form of a completely randomized design with three replications in the research greenhouse of Gorgan University of Agricultural Sciences and Natural Resources. The water source treatments included full groundwater (GW100-SW0) as a control, mixing 50% seawater and groundwater (GW50-SW50), half between seawater and groundwater (0.5-GW-SW), and one-half between seawater and Groundwater was (1-GW-SW). The results showed that the use of these water resources at the level of 1% was significant on the fresh and dry weight of root and shoot, height, total chlorophyll, vitamin C and total soluble sugar. Also, these treatments were significant on the amount of chlorophyll a and b, carotenoid and proline at the probability level of 5%. The highest amount of shoot fresh weight, root fresh weight, height and vitamin C were respectively in the control treatment with 61.5 grams, 47.5 grams, 33.2 cm and 74.6 mg per 100 grams of sample fresh weight. The findings show that in most traits, the treatment (0.5-GW-SW) has no significant difference with the control. Therefore, considering the limitation of fresh water sources, the latter treatment is suggested as a suitable source for watering purslane.
