Abstract

This study was carried out to detennine the morphology, propagation and minerals content of Neptunia oleracea Lour. from Rumah Peter, Kg. Penipah, Kg. Kekan, Kg. Medong, Mukah and Sibu Tamu, Sibu. Neptunia oleracea is a perennial, floating unattached plant and prostrate near the water edge in water reservoir at Rumah Peter, water cha1mel at Kg. Penipah and ditches at Kg. Medong and Kg. Kekan. This plant also found growing in terrestrial at Kg. Kekan. Neptunia oleracea have compound bipinnate leaves and arranged in alternate. Pinnate small, green, smooth at above and below, oblong with entire margins. The numbers of pinnate per leaflets are varying from 12--42 pinnate. Pinnate length from Rumah Peter (7.85-13.89 mm) have higher length and the lowest from Kg. Kekan (5.87-8.99 mm). Leaflets consist of2--4 pairs. Stomata presents both adaxial and abaxial leaves. Stems branched, green, covered with white spongy tissue and stoloniforous. Stems can be woody and absent of spongy tissue when grows in terrestrial such as at Kg. Kekan. Roots are red, fibrous and with nodules nitrogen-fixing at the roots and stems. The inflorescences are spike and yellow. The flower comprises 4 sepals, 5 petals, 9-10 stamens and one stigma. The fruits dehiscence and brown consists of 2-3 per peduncle and 12-18 seed per pod. From this study, the developments of the seed germination were also observed. The first sign of germination in N. oleracea is the swelling of the seeds. The compound pioneer leaves emerged with 4 pairs of leaflets followed by second, third, fourth and fifth compound leaves within 23-37 days. The compound pioneer leaves dropped 30--43 days. All stages from the beginning germination until five compound leaves approximately 2-3 months. Stem propagation, the leaves and stem propagate 100-150 cm long for 5 months. The values of macro minerals potassium in stems were higher than the leaves. The values of micro minerals zinc in leaves were higher than the leaves.
