Abstract
Abstract Effects of varying solution pH (3.75, 4.0, 4.5, 5.0 and 5.5) and Aluminum (Al) concentrations (0, 12, 21, 44, 81 and 106 uM monomeric Al, at pH 4.5) on the germination and radicle growth of soybean (Glycine max L.) cv. Fitzroy were studied on filter papers moistened with the treatment solutions. At 72 hours, germination was ≥ 85 percent at pH ≥, 4.5, but decreased to 73 percent at pH 4.0 and 53 percent at pH 3.75. Radicle length was not affected by pH in the range 4.0 to 5.5, but decreased significantly at pH 3.75 (Relative radicle length = 70 percent). Neither germination percent nor radicle length, at 72 hours, was influenced by varying Al concentrations (0 to 106 uM monomeric A1) at pH 4.5. While comparing the results of this study with those of our previous studies revealed that root growth was more sensitive to pH and Al limitations than either germination or initial radicle growth.
