  drought
Effect of Arbuscular Mycorrhiza on the Drought Tolerance of Poncirus trifoliata Seedlings
      
The effects of Glomus mosseae colonization on the plant growth and drought tolerance of 1-year-old trifoliate Poncirus trifoliata seedlings in potted culture were studied in natural water stress and rewatering conditions.
      
These results demonstrated that the drought tolerance of P.
      
The functional mechanism underlying the observation that mycorrhizas increased the host's drought tolerance was closely related to enzymatic and nonenzymatic antioxidant defense systems such as SOD, G-POD, CAT, and soluble protein.
      
The water treatments were normal growth water condition (CK), light drought water stress (T1), growth under soil water saturation (T2) and growth with soil submersion (T3).

  arid
In the semi-arid area of the Loess Plateau, Caragana korshinski, a leguminous shrub, is the dominant plant species widely used in vegetation rehabilitation programs.
      
Plant species diversity of wetland ecosystem in an arid and semi-arid region in northwest China
      
The whole study area was divided into the wetland zone, the ecotone and the arid grassland zone in terms of habitat characteristics and vegetation types.
      
The greatest evenness indices (E) were found in the arid grassland zones.
      
In the semi-arid Horqin sandy land of north China, Caragana microphylla, a leguminous shrub, is the dominant plant species and is widely used in vegetation reestablishment programs to stabilize shifting sand.

  dry
Both metalation reaction with n-butyllithium and hydrochlorination reaction with dry hydrogen chloride selectively and quantitatively occurred at the pendant reactive sites, generating polymeric benzyllithium and 1-chloroethylbenzene species.
      
An ionic liquid (IL) was prepared by directly mixing InCl3 and 1-methyl-3-butylimidazolium chloride(BMIC) with molar ratio 1:1 under dry argon atmosphere.
      
Various amounts of water were added into the dry gel to swell it, and the quantity of water in various states in the partially swollen hydrogel was determined by DSC technique.
      
The analytical results indicate that the water introduced into the dry gel first combines with the hydrophilic groups of the network chains through hydrogen bond forming non-freezable water.
      
The weight ratio of the non-freezable water to dry gel in the hydrogels is about 0.20.

  drought stress
Physio-ecological response of Haloxylon persicum photosynthetic shoots to drought stress
      
This paper studied the seasonal characteristics to resist the drought stress of Haloxylon persicum Bge.
      
It was due to stomatal limitation and osmotic organic molecules accumulation that would affect the photosynthetic shoots to resist severe drought stress.
      
Some plant aquaporins also play an important role in drought stress response.
      
The four kinds of water treatments were: normal growth water condition (CK), light drought stress (T1), soil water saturation (T2), and soil submersion (T3).
