摘要：

In this article, we adopt the apparatus invented by ourselves to investigate on the sound effects on paddy rice seeds in the germination index, height of stem, relative increase rate of fresh weight, rooting ability, activity of root system and the penetrability of cell membrane. The experiment results show that 400 Hz and 106 dB are the 'best frequency and intensity'. But when the sound wave stimulation is in excess of 4 kHz or 111 dB, it is harmful for paddy rice seeds. The study not only validates sound field stimulation can certainly promote the growth of plant, but also indicates the practicability of the apparatus. (C) 2003 Elsevier B.V. All rights reserved.
