It is commonly assumed that soil-N-15-labelling provides reliable estimates of N-2 fixation in trees by matching N-2-fixing and non-N-2-fixing tree pairs. As root system is a key parameter in determining suitability of the tree pairs, we compared roo

A complete survey of La Réunion Island showed that, in 40- to 50-year-old Casuarina cunninghamiana plantations located in the northeast at an altitude above 400 m, some trees bore aerial nodules as high as 6 to 7 m up the trunk. The nodules exhibite

Five Casuarina species and five Allocasuarina species were inoculated in vitro with three isolates of Pisolithus sp. (Ors.X004 and Ors.7870 from Senegal, PR86 from Australia) to test their ability to form ectomycorrhizas. The mycorrhiza-forming abili

The contribution of actinorhizal plants to soil productivity and rehabilitation depends not only on properties encountered in a number of non-N 2 -fixing trees but also on the input of fixed N 2 that is subsequently transferred to soil and ultimately

Since Casuarinaccae appear to be an easy plant material to handle in vitro, two approaches are worth developing. The first approach is based on exploiting natural genetic variability. Casuarinaceae species were found to be easily micropropagated and

Using the simple serial dilution technique, five strains of actinomycetes were isolated from nodules of Casuarina equisetifolia. In spite of the fact that these strains did not nodulate the host plant, they were assumed to belong to the genus Frankia
