Pot experiments were conducted in a greenhouse with the aim to study the role of antioxidant ascorbic acid <br/>under two levels (0 and 100 ppm) in minimizing and/or overcoming the phytotoxic effects of H2S (0, 50 and 100 ppm) <br/>on growth characters, some physiological and biochemical aspects; and yield quantity and quality parameters of <br/>lettuce plants. Vegetative growth parameters of H2S polluted lettuce plants were significantly reduced with <br/>increasing the H2S level. The phytotoxic effect of H2S at the high level was more pronounced and greater in <br/>head length (-31%), stem length (-34%), leaf area (-42%), fresh whole plant (-35%) and dry whole plants (-34%) <br/>matters of lettuce plant than other growth characters. Treating the H2S- polluted lettuce plants with ascorbic acid <br/>not only counteracted the harmful effect on the above-mentioned parameters, but also induced a greatly increase in them, <br/>head length (40%), stem length (104%), leaf area (82%), fresh whole plant (148%) and dry whole plant (96%) <br/>matters compared with the untreated plants. Leaf water deficit (LWD), osmotic pressure and membrane <br/>integrity (MI) were increased, whereas total water content (TWC), relative water content (RWC), <br/>transpiration rate, and the administration of H2S reduced the succulence of the leaves. Using ascorbic acid<br/>led to regulate and improve the plant water status by increasing RWC (66%) and osmotic pressure (16%), <br/>and decreasing LWD (40%), and MI (28%). All H2S levels had a deleterious effect on leaf photosynthetic <br/>pigments; chlorophyll a, b and total chlorophylls, carotenoids, total photosynthesis as well as chlorophyll <br/>stability index (CSI). Application of ascorbic acid overcame the inhibitory effect of H2S and enhanced the <br/>biosynthesis and concentration of photosynthetic pigments; chl. a (170%), chl. b (303%), total chlorophyll<br/>(186%) as well as carotenoids (64%). Exposure of lettuce plants to H2S pollutant significantly reduced the <br/>head yield, more at 100 ppm (-50%) than that at 50 ppm (-33%). The values of chemical components, <br/>i.e., vitamin C, total protein, total soluble sugars (SS), total amino acids and N, P, K minerals contents in <br/>head lettuce leaves significantly decreased with increasing the H2S level. While the Sulphur (S) contents, <br/>soluble phenols, NO3-N and NO2-N in lettuce leaves were increased as H2S rates increased. Adding <br/>ascorbic acid to the H2S-polluted lettuce plants not only led to overcome the deleterious effect of <br/>intolerable H2S levels (50 and 100 ppm) on most above-mentioned characters, but also increased the yield <br/>(150 and 169%) and improved the qualitative characters of head lettuce leaves. <br/>Key words: H2S pollutant, Ascorbic Acid, lettuce plant, vegetative growth, plant water relations, photosynthetic pigments, yield.<br/> |
