dc.description.abstractPurslane (Portulaca oleracea) is eaten extensively as a vegetable in soups and salads in the Eastern Mediterranean countries. It is an excellent source of omega-3 fatty acids, amino acids and vitamins. The objective of this study was to analyze the agronomic behaviour and the nitrate and oxalate content in several purslane cultivars grown in a hydroponic floating system. The followings cultivars were used: Two commercial cultivars ('Golden Purslane' from Tozer Seeds Company, 'C' from Pasa Seeds Company), one local Turkish accession (cv. '5') and three local Spanish accessions (215; 294; 298) from UPCT seedbank. Seeds were sown directly into 'styrofloat' trays on September 20, 2007. All the trays were placed in a growth chamber for one day, and then transferred to floatation beds located in a greenhouse. Trays were maintained floating permanently on fresh tap water. After three days, the water was replaced with nutrient solution of 8 mmol L-1 (NO3--N/ NH4+-N ratio; 60: 40). The duration of the cycle was 13 days. At the harvesting time, (when the most of the plants reached the five pairs of leaves stage) some agronomic parameters were measured and the nitrate and oxalate content were analyzed. cv. 'C' had better agronomic results reaching the highest plant height, number of leaves, leaf area and yield compared to other cultivars. On the other hand, cv. '5' was the worse cultivar in terms of agronomic parameters. cv. '215' showed the highest value of relative chlorophyll content while the Golden Purslane had the lowest. The lowest nitrate and oxalate content was found in the leaves of Turkish accession '5'. In general, cv. 'C' was the most productive cultivar, but it was less suitable for human consumption due to its high oxalate and nitrate content.en_US
