Growth and Physiological Responses of Tomato (lycopersicon Esculentum Mill.) to Simulated Acid Rain
This investigation was undertaken to ascertain the effect of simulated acid rain (SAR) on growth, yield and physiological parameters of tomato. SAR exposure (pH 3.0 and 4.0) caused white-to-tan spots on the abaxial and adaxial surface of tomato leaves. SAR exposure at pH 3.0 and 4.0 significantly suppressed pigment synthesis, shoot and root dry weights and yield of tomato. The effects were more...
متن کاملinteractive effects of salicylic acid and silicon on some physiological responses of cadmium-stressed maize seedlings
the impacts of salicylic acid and silicon on some physiological parameters of maize seedlings in the presence ofcadmium (100 μm) were investigated. inhibitory effects of cadmium on seedling growth resulted in reduced shoot and root fresh weight, low percentage of relative water content, low chlorophyll, free proline and soluble sugars contents and a low rate of lipid peroxidation. results indic...
متن کاملDifferential Sensitivity of Growth and Net Photosynthetic Rates in Five Tree Species Seedlings under Simulated Acid Rain Stress
This study investigated the effect of simulated acid rain (SAR) (heavy: pH 2.5; moderate: pH 4.0; and control: pH 5.6) stress on the growth and net photosynthetic rate (Pn) of five tree species, namely Castanopsis sclerophylla, Cinnamomum camphora, Manglietia fordiana, Pinus massoniana, and Elaeocarpus glabripetalus. Results showed variable responses to SAR with different pH values depending on...
متن کاملPhysiological and biochemical responses of Quercus brantii seedlings to water deficit stress
Water shortage is one of the most important environmental stresses in Mediterranean regions. Poor seedling quality may account for the failure of oak regeneration. To determine the best seed origin of Quercus brantii, we investigated on seedlings collected from 20 mother trees in the Zagros Mountain forests 700 to 2200 m altitudes above sea level. Seedlings from different altitudes were irrig...
متن کاملBiochemical and physiological responses in in vitro germinated seedlings of Brassica juncea exposed to metal stress
Background: Effects of cadmium (Cd) metal on growth, photosynthetic pigments, level of osmolytes and elements, and antioxidant potential of Brassica juncea seedlings were evaluated. Materials and Methods: Seeds were exposed to different concentrations of metal, i.e., 0, 0.2, 0.4, and 0.6 mM Cd. To investigate the metal influence on biochemical and physiological factors, observations were made o...
