    Abstract:
    Acoustic emissions (AE) could be used as an indicator of plant water stress as "speaking plant". The objective of this study was to observe the AE of tomato plant and to analyze the relationship between AE and plant water consumption associated with transpiration. Three glasshouse experiments were conducted with potted tomato plants. The AE, transpiration rate and "the plant transpiration transfer coefficient (hat)" as an indicator of plant water stress level were determined with hat being calculated based on sunlit leaf temperature, temperature of an artificial leaf without transpiration (hereafter,referred to as "non-transpiration leaf temperature") and air temperature. The results showed that the daily patterns of the AE varied depending on the water stress level, which was indicated by hat. Under mild or moderate water stress (hat ≦0) conditions, the AE increased with the decrease in the amount of soil water but decreased with the decrease in the amount of soil water under severe water stress conditions (0

    The water physiology of locust seedling under conditions of different drought stress was tested. The results showed that transpiration rate, leaf RWC, water potential and water-consumption, water use coefficient decreased with soil water decreasing, and leaf WSD increased with soil water decreasing. Meanwhile, some problems were pointed out and discussed.

    The photosynthetic properties and water use efficiency changes of Sonchus branchyotus DC.seedlings were measured in drought stress with pot culture experiments simulating different soil water status.The results showed that the chlorophyll content first ascended and then declined and the net photosynthetic rate,transpiration rate,intercellular CO2 concentration and Stomatal Conductance decreased along with drought stress increasing.The water use efficiency increased in light and moderate drought stress.Sonchus branchyotus DC.showed high adaptability to drought stress.

    Transpiration of twenty-nine potted afforestation species for vegetation restoration in the dry-hot valleys of the Jinsha River was studied under different drought stress weight on typical sunny day.Five main conclusions were gotten as follows:(1)The transpiring water consumption of different seedlings in the day time presented a sustained descent with the drought stress,the descending extent of different seedlings was obviously different.The seedlings,with the strong water consumption,were more easy and quick to suffer from drought stress.(2) After six-day's drought treatment,the practical water consumption of Acacia mearnsii,Leucaena leucocephala cv.Salvador,Carallia longipes,Eucalyptus globulus descended the most,being 85.78%~93.11%; Schleichera oleosa,Bombax malabaricum,Tephrosia candida,Albizia kalkora,Pinus yunnanensis descended the least,being only 6.37%~17.42%.The classified result by the descended extent of water consumption was identical to the comparison result of slope k.(3) The transpiring water consumption of seedlings in the first day determined the dynamic variation of water losing.With the sustaining of drought stress,the proportion of water consumption in the night to water consumption in the whole day gradually increased.(4) When the seedlings suffered serious drought stress in March,the descending proportion order of transpiring from water consumption of twenty-five species was identical to the size order while suffering from middle-class drought stress.(5) According to the quantitative formula between transpiring water consumption rate of seedlings in the day time,systematically classified method could be used to divide twenty-nine tree species into four classifications including high transpiring water consumption,sub-high transpiring water consumption,sub-low transpiring water consumption and low transpiring water consumption.

    In this trial,the effect of foliar spraying S-ABA on the water consumption of corn plant under high temperature and drought stress was studied.The results showed that the leaf stomata conductance fall,and the leaf transpiration rate decreased,and the corn plant water consumption decreased by spraying S-ABA under the high temperature and drought stress.

    The photosynthetic characters and water use efficiency were measured under drought stress with six sugarcane materials planted in pots.The results showed that net photosynthetic rate,transpiration rate and stomatal conductance all decreased,but intercellular CO2 concentration and water use efficiency had different change tendency with the increasing of drought stress time.There was higher correlation among photosynthetic traits in different sugarcane materials.ROC22 and S.spontaneum L.performed to be highly resistant to drought.Fruit Sugarcane and KN90-445 performed middle resistance.S.robustum Brandes et Jeswiet ex Grassl and ROC16 performed to be poor resistant to drought.
