Abstract:
In recent years, the idea has flourished that plants emit and perceive sound and could even be capable of exchanging information through the acoustic channel. While research into plant bioacoustics is still in its infancy, with potentially fascinating discoveries awaiting ahead, here we show that the current knowledge is not conclusive. While plants do emit sounds under biotic and abiotic stresses such as drought, these sounds are high-pitched, of low intensity, and propagate only to a short distance. Most studies suggesting plant sensitivity to airborne sound actually concern the perception of substrate vibrations from the soil or plant part. In short, while low-frequency, high-intensity sounds emitted by a loudspeaker close to the plant seem to have tangible effects on various plant processes such as growth - a finding with possible applications in agriculture - it is unlikely that plants can perceive the sounds they produce, at least over long distances. So far, there is no evidence of plants communicating with each other via the acoustic channel.
摘要:
近年来,植物发出和感知声音,甚至能够通过声音通道交换信息,这种想法已经盛行。虽然对植物生物声学的研究仍处于起步阶段,伴随着潜在的迷人发现,在这里,我们表明,目前的知识是没有定论。虽然植物确实在干旱等生物和非生物胁迫下发出声音,这些声音是高音的,低强度,并且只能传播到很短的距离。大多数表明植物对空气传播声音敏感性的研究实际上涉及土壤或植物部分对基质振动的感知。总之,而低频,靠近植物的扬声器发出的高强度声音似乎对各种植物过程有切实的影响,如生长-这一发现可能在农业中应用-植物不太可能感知它们产生的声音,至少在很长的距离。到目前为止,没有证据表明植物通过声学通道相互交流。
