Abstract

In order to understand the effects of different chemical reagents on the growth of Cyclobalanopsis glauca container seedlings, the chemical root control concentrations of CuSO4 40, 80, 140, 220 gL－1, ZnSO4 40, 80, 140, 220 gL－1, Al2（SO4）3 40, 80, 140, 220 gL－1, and 2,6-Dinitro-N,N-dipropyl-4-（trifluoromethyl）aniline 0.04, 0.08, 0.14, 0.22 gL－1 were mixed with emulsion varnish and then coated on the inner wall of root control bags. These were compared to a treatment where the inner wall was coated on only with emulsion varnish. Then the effect of the chemical reagents on root configuration indexes, root activity, height, base diameter, biomass accumulation, and quality index of four-year-old Cyclobalanopsis glauca container seedlings were analyzed. Results showed that: （1） reagents of CuSO4, ZnSO4 and Al2（SO4）3 in the range of 0－140 gL－1 as well as 2,6-dinitro-N,N-dipropyl-4-（trifluoromethyl） aniline in the range of 0－0.22 gL－1 regulated root growth and development of C. glauca, but reagent of 220 gL－1 ZnSO4had a negative effect on seedlings. （2） Root tips, volume, surface area, projected area, forks, and activity, as well as plant height, basal diameter, shoot dry weight, root dry weight and quality index treated with 140 gL－1 CuSO4 reagent significantly increased （P＜0.05）, whereas root average diameter and length of taproot significantly decreased （P＜0.05）. Seedlings treated with different chemical reagents showed improved root controling with the best treatment being 140 gL－1 ZnSO4. ［Ch, 4 fig. 2 tab. 15 ref.］
