Acacia auriculiformis is a fast growing species planted on vertisols in Benin. An inventory of 11 mixed stands of Acacia, which are 7 to 9 years old, has been realized to estimate growth parameters of the stands. The present study shows that, for the dendrometrical parameters, there is no difference between species associations at a 0.05 significance level. Nevertheless, the largest values of quadratic mean diameter of the stems foot are observed in the species associations including Leucaena leucocephala. Moreover, the branch volume decreases with the increasing of the number of stems per tree. The most appropriate volume function for Acacia auriculiformis is the one that takes into account the diameter of the stems foot and the total height. Otherwise, the species associations do not influence the profile of Acacia trees, which is constant within the associations. The predicted conversion and cutting coefficients show that the stacked wood volume represents about 144 % of the real stand volume. [less ▲]

The paper presents an original method dealing with the forest site types delineation. The suggested method consists in integrating a typological key in a GIS aiming at producing a thematic map that describes forest site types. Data used are the soil map of Belgium (digitized at the scale 1:20,000) and a digital elevation model built from a topographic map (scale 1:10,000). The typological key is mainly based on the methodology used by Thill et al. (1988) in the site types system for central Ardenne, the potential vegetation map of Sougnez and Dethioux (1975) and the ecoregion map of Delvaux and Galoux (1962). In that respect, site types are closely linked to the soil map and the phytosociological classification. So, they can be connected to the afforestation guide and different phytosociological and autecological studies concerning forest species. It is then possible to map the potential habitats or the site potentialities related to tree species. The key is valid for the Ardenne ecoregion located in Southern Belgium (elevation higher than 300 m). It has to be validated through an intensive use in the field, taking into account its imprecision linked to the types of collected data, chieffly those being digitized. The integration of such a tool in a SIG can be considered as an original way in terms of integrated forest management or forest sites description in the context of the project “Natura 2000” launched by the European Union. The study has been carried out within the framework of an experimental integrated management project concerning the Saint-Hubert forest (17,000 ha). [less ▲]

Divinyl ether synthase, an enzyme of the lipoxygenase pathway transforms, in potato tubers, 9-hydroperoxides of fatty acids into colneleic and colnelenic acid, two divinyl ethers of fatty acids. The enzyme has been described in a limited number of quite different plants. The enzyme has also been detected in tomato roots, garlic bulbs, tobacco plants and in marine algae. The enzyme is bound to membranes and is located in the microsomal fraction. The molecular weight of the enzyme exceeds 100,000 Da, its optimal pH is around 9 and its high specificity for 9-hydroperoxides as substrate is described. The reactional mechanism has been elucidated using radio-labelled molecules. Colneleic and colnelenic acid can be degraded enzymatically or not into aldehydes and oxo-acids. Those last compounds are also formed by the action of hydroperoxide lyase on 9-hydroperoxides of fatty acids. As other enzymes of the lipoxygenase pathway, reaction products of divinyl ether synthase are involved in pathogenic resistance. Colneleic and colnelenic acid content in potato plants has been corelated with resistance to Phytophthora infestans. [less ▲]

Sugar esters are nonionic surfactants and exhibit relevant properties such as structural diversity and environmental and health safety. Their potential applications extend from human food to drug formulations and biochemical studies. Some sugar esters also exhibit interesting biological activities. Many papers on the subject have been submitted during the last 10 years. Those articles describe the various ways of synthesis of those compounds at the laboratory scale. During the last 10 years, the most studied method was the biotechnological one using catalysis by enzymes. Available knowledge on these molecules is reviewed. [less ▲]
