The current exploitation of rosemary and myrtle (native species with relatively high yield of EO) occupies an important place in the forestry sector and a significant socio-economic interest. Eucalyptus trees can play a predominant and substantial role thanks to their richness in essential oils, their composition and their commercial value.
This objective necessarily involves the identification of eucalyptus EO species and the selection of the most efficient in terms of the yield of essential oils and the presence of the most dominant active compounds which are preferentially sought...
The main objective of this factsheet is to help technicians and forsters to recognize, in the field, insect gall wasps of Eucalyptus species.
The Montpellier maple (Acer monspessulanum L.) is a Mediterranean and West Asian species considered in Tunisia as rare with only three locations. The ecological importance of the species as a broadleaf and its effects on its natural ecosystem leads us to get a clear idea of the best way of propagation using seeds.
Resin is a natural product that has multiple applications and is highly demanded in the chemical industry. As a non-timber forest product, exploitation of the abundant pine resin in Tunisian forests (50% of the forest area) can contribute to a bioeconomy and can generate additional income for forest populations.
Pine species are considered as a natural source of antioxidant compounds. Pinus nigra Arnold is one of the most known medicinal plants in the Mediterranean countries. The aim of this study was to determine, for the first time, the bioactive compounds such as the total phenols, flavonoids and tannins and to evaluate the antioxidant potential of needles collected from nineteen samples corresponding to different provenances of black pine from different regions which have been planted and grown in Northwestern Tunisia.
Among essential oils, Eucalyptus oil, is one of the most useful as it is easily extractable commercially (industrial value) and possesses a wide range of desirable properties worth exploiting for pest management. Eucalyptus oils are mainly extracted from leaves which can be attacked by gall wasps as Ophelimus maskelli. Induced galls can affect the essential oil production.
This work aims to determine the role of the parasitoid Closterocerus chamaeleon in the biological control of its host O. maskelli.
Aleppo pine is one of the dominant forest species in Tunisia, favoured by its great regeneration capacity, plasticity, climatic stress tolerance, and multiple products: wood, edible seeds, vegetable seed oil, essential oils from leaves. For these reasons it has been used massively as for reforestation.
But the wide geographical distribution of the species might imply variation in adaptive and productive traits. The use of genetic material well adapted to the environment and better performing allows for valorization of the resource and offers a guarantee of success for new...
The wide potential of resin acids as bioactive agents could be considered as very promoting products for new applications of the natural forms and their derivatives.
The objective of the present investigation was mainly focused on the assessment of the biological performance of the resin. Therefore, the evaluation of the antibacterial activity of the three Tunisian pine species Pinus pinaster, Pinus pinea, and Pinus halepensis were conducted in order to control four pathogenic bacteria species.
The main objective of the present investigation is to explore the knowledge and the best practices of resin extraction technics in rural areas and marginal environment in order to promote the live condition of the population in these different regions by providing secure incomes and good working conditions. This could lead to the best evaluation of the good performance of the three most important pine species in North-western of Tunisia to resin extraction.
In Tunisia, the cork oak is facing various difficulties namely: severe ecological conditions, very heterogeneous stands with variable density, and strong pressure on the forest. Reforestation has become an essential alternative to regenerate old cork oak forests and to support natural regeneration. Selecting adequate plant material with good genetic quality is important to ensure high adaptation to environmental hazards. In this context, the main objective is to explore and evaluate the genetic variability among different stands to select and conserve the best genetic material.
The exploitation of pine forests in Tunisia which covered up to 50% of the total forest area could contribute and generate additional income sources for forest populations. Until now, the resin extraction knowledge was very limited and outdated. In the present study, the assessment of the biological performance of the resin was the main objective in order to detect the antioxidant activity of three pine species in the Tunisian forest.
