Abstract: Experiments are made on soybean and peanut plants,using simulated acid rain with different pH values.The perceptable injury,plant height,leaf area,dry matter,chlorophyll content,membrane eonductance of leaf cell and other productive parameters are measured undervarious acid rain conditions.Their acidity thresholds are also determined.Acid rains affectthe above parameters to various degrees,but an acid rain of pH 3.5 has some promotiveeffects on the dry matter weight per plant and economic yield of peanut.

Key words: peanut, Ca fertilizer, Cd stress, physiological characteristics, yield, kernel quality
