Water consumption and transpiration for seedlings of three ornamental tree species in Beijing

    Corresponding author: MA Lü-yi

Abstract: The objective is to contribute to the theoretical basis for reasonable selection of greening tree species and its water management. Water consumption characteristics due to transpiration for three ornamental tree species;namely Magnolia denudata,Liriodendron chinense,and Robinia pseudoacacia;were systematically studied in Beijing using a Li-6400 Portable Photosynthesis System and BP-3400 precision electronic balance. Results showed that 1)the spring transpiration rate of these three trees was higher than summer and autumn;2)daily water consumption for these species was greatest in spring;and 3)the annual average daily water consumption rates were in the order:M. denudata (1.493 8 kg·m -2·d -1) > L. chinense(1.234 1 kg·m -2·d -1) > R. pseudoacacia (0.623 6 kg·m -2·d -1). The rate of annual average daily water consumption is important for evaluating the water consumption capability of a tree.[Ch,4 fig. 1 tab. 19 ref.]
