| Summary: | Excessive use of chemical fertilizers and pesticides causes pollution of soil, water, and the atmosphere. Biostimulants are derived from natural sources, which can help plants absorb nutrients and promote plant development. Chinese herbal medicine extracts are enriched with bioactive compounds and therefore hold great potential for developing novel biostimulants. In this study, the predominant active compound, baicalin, was detected in Scutellaria baicalensis Georgi ('Huangqin' in Chinese) extracts via LC-MS/MS. To explore their effects, we used three different methods to treat tomato seedlings with Scutellaria baicalensis Georgi (S. baicalensis) extracts or baicalin, including foliar spraying (S), root irrigation (R), and the combination of foliar spraying and root irrigation (SR). Both S. baicalensis crude extracts and commercial baicalin promoted stem and root development, enhanced the photosynthetic capacity, and increased tomato seeding biomass, eventually making tomato seedlings grow vigorously. Clustering analysis and principal component analysis showed that S. baicalensis extracts and baicalin had very similar effects and showed the best effects in SR treatment. S. baicalensis extracts and its active compound baicalin could promote tomato seedling growth, suggesting that S. baicalensis is a potential source of biostimulants. |
