Abstract
This study was conducted to determine the effect of simulated acid rain of pH 3.0, 4.0 and 5.6 on pollen grain germination and yield in rice (Oryza sativa L.) plants. Results indicated that direct exposure to acid rain of pH 3.0 and pH 4.0 acid rain reduced pollen grain germination by up to 30% and 10%, respectively.
本試驗主要探討水稻開花時人工模擬酸雨對花粉發芽的影響，並以田間資料探討影響產量減少的原因。結果顯示，水稻在開花時，直接噴施pH 3.0及pH 4.0的酸雨時花粉發芽率分別受抑制30％及10％，另發芽率降低將使穀粒結實率、每穗小花數及產量下降。
