| Abstract: |
| 【Objective】To explore the effect of different soil moisture content on the growth and related q-uality 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, chlorophyl, flavonoids, polysac-charides and characteristics of Taihang taxus in five different soil moisture content which was 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, chlor-ophyll b, total chlorophyll all reach highest level, Compared with treatment W1, the results were improved by 11.4%, 26.7%, 11.7%, 15.6%, 14.4%, 8.9% and 13.0%, and the malondialdehyde content was the lowestin the treatment group, it was 14.1% lower than treatment W1; treatment W4 had the highest amount of polysaccharide and soluble protein, Compared with treatment W1, 107.5% and 42.0% were improved respectively; treatment W3 had the highest amount of flavonoids, it was 93.6% higher than treatment W1.【Conclusion】treatment W2 is good for growth in Taihang Taxus, treatment W3 is good for accumulating flavonoidsin Taihang Taxus, treatment W4 is good for accumulating polysacchardes in Taihang Taxus. |
