e0“At these same treatment levels total non‐structural carbohydrates did not decrease significantly”
e1“seeds of soybean plants exposed to simulated acidic rain grown under standard agronomic practices and receiving ambient rainfall at Brookhaven National Laboratory during the summer of 1979. Plots were exposed three times per week to simulated rainfalls of pH 4·0, 3·1, 2·7 or 2·3 to provide inputs of 50, 397, 998 or 2506 μequiv. of hydrogen ions respectively, above ambient levels throughout the growing season. Control plots received no simulated rainfall treatments.”
