Read More There is considerable concern that use of high nitrate and nitrite containing vegetables such as spinach could cause diseases. This research was conducted with the objective of examining the nitrate (NO3-) and nitrite (NO2-) accumulation in the aerial parts (leaves and petiols) of 44 Iranian spinach (Spinaciaoleracea L.) land races that were obtained from field grown plants. Statistical analysis was conducted by using standard procedures for a randomized complete block design (44 treatments and 3 replications). Nitrate and nitrite contents in the aerial part of samples were determined using UV-Visible Spectrophotometric. Results indicated that the nitrate content in the aerial part of Iranian spinach land races ranged from 3526.5 to 8806.5 μg.g-1 dry weight. The ‘Saleh Abad’ (from ‘Qom’), ‘Rehnan’ (from ‘Isfahan’), ‘Sar Asyab-1’ (from ‘Kerman’), ‘Sirjan’ (from ‘Kerman’), ‘Qazvin’, ‘Zanjan-2’ and ‘Khoram Abad’ were found to contain maximum accumulation on nitrate (8806.5 to 7092 μg.g-1 dry weight). Nitrate concentration in leaves of ‘Sar Asyab-2’ (from ‘Kerman’) and ‘Mahan’ (from ‘Kerman’) was significantly low (3526.5 to 3594 μg.g-1 dry weight, respectively). The nitrite contents were lower (between 73.8 to 188.7 μg.g-1 dry weight( than nitrate content in all Iranian spinach land races. The different spinach land races show the significant effect on the nitrite contents in this study. Spinach land races which were collected from ‘Khoram Abad’, ‘Varamin-1’, ‘Mahan’, ‘Bojnord-1’, ‘Qom’, ‘Sari-2’and ‘Ravar’ (from ‘Kerman’) showed the lowest average of nitrate contents among other land races, with a range of 73.8 to 89.51 μg.g-1 dry weight. While the highest nitrite content in spinach land races were with a range of 188.7 to 163.1 μg.g-1 for ‘Sar Asyab-1’ (from ‘Kerman’), ‘Yazd’, ‘Hamedan’, ‘Karaj’ and ‘Bor An’(from ‘Isfahan’). Results indicated that the mean of nitrate or nitrite content in these land races were statistically significant.The variation of nitrate content in the leaves of Iranian spinach land races also make them ideal for breeding program.

Read More With respect to arid and semi-arid climate of Iran, using methods which mitigate detrimental effects of water deficit on horticultural products would be of significant importance. Kaolin is an anti-transpiration material the application of which has been expanded during the recent years. For this purpose, the effect of three different levels of kaolin (0, 3 and 6%) as well as three different levels of irrigation (100, 65 and 40% potential ETcrop) on chlorophyll content and chlorophyll fluorescence in olive leaves “Dezful’ were examined as factorial test based on a completely randomized design in three replications (each replication including 3 pots) in the greenhouse of Horticulture Department, Faculty of Agriculture, Tarbiat Modares University (Tehran, Iran). The obtained results demonstrated that chlorophyll a and total chlorophyll were reduced under water deficit. The amount of reducing of chlorophyll a and total chlorophyll in 80 days after treatment was greater than that in 40 days after treatment. In addition, the amount of total chlorophyll in the sprayed plants with 6% kaolin was the highest (1.425 mg/g fresh weigh of leaf) in 80 days after treatment. Furthermore, it was shown that by reducing of water content to 65 and 40% ETcrop the content of chlorophyll “a” was greater than the plants which were sprayed at kaolin concentrations of 3 and 6% in comparison with the control. Meanwhile, the results of fluorescence parameters showed that maximum fluorescence indices (Fm), fluorescence variable (Fv) and ratio of fluorescence variable to maximum fluorescence (Fv/Fm) were reduced under drought stress. However, the kaolin treatment had no significant effect on these indices. Generally, it can be expected that spraying of the olive gardens in Iran with kaolin, especially in regions exposed to water deficit can moderate the drought stress and mitigate the detrimental effects of water deficit, while improving photosynthesis efficiency of the leaf.
