Micromorphological Studies of Four Fuel Wood Yielding Tropical Leguminous Plants

Metabolism of l-Canavanine and l-Canaline in Leguminous Plants.

Massive accumulation of l-canavanine, the 2-amino-4-(guanidinooxy)butyric acid structural analog of l-arginine, occurs in many legumes. Accumulation of large amounts of this nonprotein amino acid results in large part from canavanine's protective efficacy; it forms an effective chemical barrier to predation, disease, and even competition with other plants. Diversion of metabolic resources for t...

Histological Responses of Four Leguminous Crops Infected with Meloidogyne incognita.

Histological responses to Meloidogyne incognita infection in Rhizobium nodules of clover, horsebean, lupine, and pea were investigated. The formation of giant cells in vascular bundles of nodules and roots, and the basal connection of the nodule, were usually associated with abnormal xylem and/or deformed xylem strands. However, giant cells did not disturb or prevent the development of nodular ...

Wood Fuel Properties and Fuel Products from Woods

The fuel properties of wood can be summarized by ultimate and proximate analysis and determination of the high heating value. It is not valid to list these values for species since a species has not been adequately sampled and tested. Enough is known, however, to say that softwoods have a high heating value of about 9,000 Btu per pound; whereas hardwoods have a value of about 8,600 Btu per poun...
