象父母被口渴的小孩吵醒一样,人们也会听到植物缺水时所发出的声响.小型话筒和超敏感电子测定仪器使科学家记录到这种声音成为可能.不久前,美国植物生理学家曾监听了玉米木质部内发出的高频率短促爆裂声.这种声响是木质部在运输水分的过程中产生的. Like parents being thirsty children wake up, people will hear the sound of plants when the sound of the small microphones and ultra-sensitive electronic measuring instruments so that scientists have recorded this sound possible.Not long ago, the United States of America plant physiologist He had listened to the high-frequency rupture of the high frequency emitted by the xylem in the corn, which was generated during the transport of moisture by the xylem.
