Abstract

Twelve families of non-legumin us flowering plants containing of species most commonly found in low nutrient soils were surveyed for the presence of root nodules. Five species namely, Casuarina equisetifolia Forst, C. rumphiana Nig, Elacagrus philippinensis err. Cycas circinalis L. and C. revoluta Thumc., were found possessing root nodules that were capable of dinitrogen fixation. Roots of species found actively growing in poor nutrient soils were tested for acetylene reduction activity. All of them showed signs of weak nitrogenase activity. The role of nitrogen fixation in their ability to survive in low nutrient soils remains a fascinating area for future research specially in term of their pssible use in reforestation activities.
