| Abstract/Contents: | "Biosolids can improve the physical and chemical properties of soil, and promote plant growth. The aim of this research was to study the effects of biosolids on the growth and auxin metabolism of Poa pratensis. A split-plot experiment under the same nitrogen supply level and different water regimes was used, with the main-plot treatments being drought stress and sufficient water supply. The split-plot treatments were biosolids and hormone treatments, namely: indole-3-butytric acid, biosolids, biosolids with added tryptophan, tryptophan and a blank control with no additions. The results showed that biosolids significantly reduced damage to turf quality and ameliorated reductions in chlorophyll and carotenoid content of leaves (P<0.05). Under different water conditions, both the biosolids and tryptophan increased the content of tryptophan and indoleacetic acid in the roots, while the biosolids significantly increased indoleacetic acid and tryptophan levels in the root system and leaves, and biosolids mixed with tryptophan was more effective than biosolids alone (P<0.05). In summary, the application of biosolids significantly promoted turfgrass growth, increased the chlorophyll and carotenoid content of Kentucky bluegrass leaves under drought stress. Application of biosolids can also increased the content of tryptophan and indoleacetic acid in the leaves and roots, and increased the photosynthetic rate of P. pratensis and enhanced its drought resistance." |
