Responses of Fraxinus rhynchophylla Seedlings to Shading Under Different Lilght Regimes
Under different light regimes:55.44% natural sunlight (NS), 21.12% NS,3.47% NS and 0.86% NS in shade house, the growth characteristics of Fraxinus rhynchophylla seedlings were observed. The results showed that seedling height, basal shoot diameter, taproot length, leaf area per seedling, total dry weight, relative growth rate and net assimilation rate all maximized (70.0 cm, 6.84 mm, 31.95 cm, 798.80 cm~2, 10.28 g, 31.13×10~(-3)g·d~(-1), and 3.25×10~(-5) g·cm~(-2)·d~(-1) respectively) under 55.44% NS shade treatment and reduced with the decrease of light intensity. With the reduction of light intensity, the specific leaf area of F. Rhynchophylla seedlings increased to its maximum (597.43 cm~2·g~(-1)) under the shade treatment of 3.47% NS, after which a decrease was observed.
