Abstract:
Sweet basil is an economically important plant, and its essential oils, synthesised and stored in glandular hairs, are widely used in several industries. In the present paper, the effects induced by three arbuscular mycorrhizal fungi (Glomus mosseae or Gigaspora margarita or Gigaspora rosea) on shoot and leaf development of Ocimum basilicum var. Genovese were evaluated. Results showed that different fungi can induce different effects on the same plant. NIR (Near Infra Red) Spectroscopy of intact leaf and Electronic Nose analysis both confirmed a high level of variability (Rē>0.5), therefore NIR well distinguished inoculated and control plants while EN figures were closer to the chemical aromatic profiles. A potential application of such techniques is discussed.
