| Abstract: |
| 【Objective】The aim of this study is to explore the effects of different soil moisture content on the growth and related quality of Taihang Taxus in potted plants.【Method】Taking five-year-old Taihang Taxus as the test materials, an investigation was made on the growth, soluble protein, malondialdehyde, chlorophyll, flavonoids, polysac-charides and characteristics of Taihang Taxus in five different soil moisture contents which were set as 90%～100%(W1), 80%～90%(W2), 70%～80%(W3), 60%～70%(W4) and 50%～60%(W5) of the maximum soil field capacity.【Result】In treatment W2 the plant height, stem diameter, canopy, leaf area index and chlorophyll a, chlorophyll b, total chlorophyll all reached the highest level. Compared with those in treatment W1, the results were improved by 11.4%, 26.7%, 11.7%, 15.6%, 14.4%, 8.9% and 13.0% respectively, and the malondialdehyde content was the lowest in the treatment groups, which was 14.1% lower than that in treatment W1. Treatment W4 had the highest amount of polysaccharideand soluble protein. When compared with treatment W1, 107.5% and 42.0% were improved for polysaccharideand soluble protein, respectively. Treatment W3 had the highest amount of flavonoids, which was 93.6% higher than that in treatment W1. 【Conclusion】Treatment W2 is good for growth in Taihang Taxus, and treatment W3 is good for accumulating flavonoidsin Taihang Taxus,while treatment W4 is good for accumulating polysacchardes in Taihang Taxus. |
