Abstract
The experiments were performed to examine the effects of simulated acid rain (pH 1.05.0) prepared by mixing sulfuric acid and nitric acid at the ratio of 3 : 1 on germination and growth of seedlings of some floricultural crops. Days to germination showed a one to three days' interval among crops, but pH level did not show any effect on germination for each crop. All seeds used in this experiment did not germinate at pH 1.0. At pH 2.0, the flowering cabbage and geranium still did not germinate, and even though the radicles of seeds were germinated, root hairs did not develop. The length of hypocotyls and radicles appeared to be significantly different according to the pH levels.
