The relationships among species and the mechanics of those are very complicated in mixed forests, allelopathy is one most important mediators these relationships. types quantities allelopathic chemicals different coniferous broadleaved trees; studying responses some sensitive plants, such as certain crops, to mediated by leaf extracts trees would be an effective technique evaluate a forest. In this paper, effects from Metasequoia glyptostroboides, Cedrus deodara, Liquidambar formosana, Platanus acerifolia mixture on seed germination seedling growth Sesamum indicum at constant concentration (50 gDW/L) were investigated using indoor filter paper culture dish method. test results evaluated response index (RI) synthesis effect (SE). showed that: (1) Four kinds inhibited S. indicum. order inhibitory follows: L. formosana > M. glyptostroboides C. deodara P. acerifolia; (2) experiment, single extract (M. deodara) (L. acerifolia) did not exhibit significant differences direction indicum; (3) Compared their corresponding extracts, + promoted indicum, namely, coniferous-broadleaved another extract. rest treatment groups neutralized conclusions could provide scientific basis for managing especially forest ecosystems.

Allelopathic Activity of Leaf Wastes of Liriodendron tulipifera for Sustainable Management

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(18), P. 8437 - 8437

Logging operations of Liriodendron tulipifera L., as timber trees, and fallen leaves in autumn from ornamental trees produce a large amount leaf waste. In this study, the allelopathy L. fresh was investigated for development potential applications The extracts showed growth inhibitory activity against weed species, Vulpia myuros (L.) C.C.Gmel., Echinochloa crus-galli P.Beauv., Lolium multiflorum Lam., under laboratory conditions. powder also inhibited germination E. greenhouse A potent allelochemical isolated through bioassay-guided separation process, identified lipiferolide. Lipiferolide Lepidum sativum concentration-dependent manner. This investigation suggests that waste logging is potentially useful purpose control, such use soil additive materials or creation foliar spray extracts. control using may be means with which to minimize waste, reducing environmental impacts economic concerns.
