  • Title: [Effects of drought stress on the biomass distribution and photosynthetic characteristics of cluster mulberry].
    Author: Yan HX, Fang LB, Huang DZ.
    Journal: Ying Yong Sheng Tai Xue Bao; 2011 Dec; 22(12):3365-70. PubMed ID: 22384610.
    Abstract:
    One-year-old Morus alba seedlings were cultivated in pots containing soil with different water contents to study the biomass, chlorophyll fluorescence parameters, net photosynthesis rate, stomatal conductance, transpiration rate and water use efficiency of the seedlings in response to diverse water stress. The results showed that the aboveground biomass and total biomass decreased with increasing water stress. However, more photosynthetic products were transferred to the roots in relation to the aboveground parts to make the root-shoot ratio increase. The fluorescence parameters, such as F(o), F(v) and F(v)/F(m), and stomatal conductance, transpiration rate and water use efficiency decreased with increasing water stress.
