By foliar application of a range of methanol solutions (0, 2.5, 5, 7.5, 10 %, v/v) on leaves of salt-stressed soybean seedlings, and comparing changes in plant height and relative electrolytic leakage, the appropriate concentration of foliar methanol for mitigating of salt injury to soybean was selected. On this basis, foliar application of the appropriate(More)
Chinese river dolphin's (Lipotes vexillifer) underwater acoustic signals can be divided into two classes, short-duration signal (pulse train or single pulses) and long-duration signal (whistle).
