Abstract
Pistacia lentiscus var.
Chia is known for the production of the valuable resin of mastic gum or “mastiha” and use as ornamental.
Experiments were carried out on young mastic trees (4 years old), propagated by shoot cuttings, growing in 10 L pots (peat and local soil) in Chios Island.
The canopy of plants, including branches, was sprayed with methyl jasmonate (0.2, 2.2, and 22 mL L‑1), salicylic acid (0.069, 0.69 and 6.9 g L‑1), abscisic acid (2.64, 26.4 and 264 mg L‑1) or Ethrel (ethylene, 0.5, 5, and 50 mL L‑1). Furthermore, ‘Humicraft’ (humic acids, 10 mL pot-1), ‘Humi-forte’ (humic acids 0.02 mL pot-1), ‘Bacillomix’ (active mycorrhizae, 30 μL pot-1), ‘Amino16’ (amino acids, 200 µL pot-1) and ‘Symbivit’ (mycorrhizal fungi, 50 g pot-1) were applied.
To check for the existence of possible symbiotic fungi: 1) local soil with mastic tree roots was used or 2) the same substrate was watered with fungicides (30 g pot-1). The mechanical process of wounding the trunk and thick branches to induce the production of mastiha was applied to the young plants simultaneously with the treatments.
After one month, the mastiha production, photosynthetic rate, chlorophyll content index and chlorophyll fluorescence were recorded.
It was observed that 5 and 50 mL L‑1 of Ethrel caused a severe senescence to the leaves, whereas Ethrel and methyl jasmonate provoked the highest production of mastiha (83.82-91.57 mg
plant-1) compared to the control (37.14 mg plant-1).The use of local soil recorded the highest rate of chlorophyll, whereas the application of fungicides resulted in lower chlorophyll fluorescence and less mastiha production, suggesting active symbiotic fungi on the roots of P. lentiscus in the local soil.
