Overview

Randomized trial investigates allelopathic effects of Ocimum species on lettuce growth, suggesting sustainable weed management insights.

Key Points

  • This research aims to evaluate the inhibitory effects of Ocimum basilicum and O. tenuiflorum extracts on lettuce seed germination and seedling growth.
  • Examined extracts and essential oils from Ocimum basilicum and O. tenuiflorum
  • Conducted assays to measure seed germination and seedling growth in lettuce
  • Identified major volatile constituents and their IC50 values for inhibition.
  • O. basilicum leaf extract showed potent allelopathic inhibition (IC50, 0.42 mg ml–1).
  • O. tenuiflorum essential oil was more suppressive than O. basilicum (IC50, 5.5 for germination, 7.9 for shoot, 2.6 for root).
  • Linalool and eugenol demonstrated significant inhibitory effects on lettuce germination (IC50, 1.72 and 1.69 nl cm–3, respectively).
