Variasi Morfologi Kepundung (Baccaurea recemosa Muell. Arg) di Sumatera Utara Bagian Selatan

Abstract

The research about morfological and ecological variation of kepundung in southern North Sumatera had been carried out in order to get the data about morphological and ecological kepundung in North Sumatera from December 2014 to April 2015. The collection of data are carried out in South Tapanuli, Mandailing Natal, Padang Lawas and Padangsidimpuan by exploring and collecting the vegetative and generative morphological organ, the physical factor of the chemistry soil (N, P, and K element), spreading and the secondary metabolic contents. The result of research of morphological organ shows the variation of leaves, the fruit texture, the colour of the fruit. The analysis of N, P and K shows the difference in every regency. The nitrogens has its level between 0,17-1,61 %, phosphor has its level 11,68-15,47 ppm, and potassium 0,577--0,735 m.e/100 g. The analysis of ecology shows that kepundung grows between 3 500- 4000 mm/year. The kind of soil is fluvisol, the mixed dried farming habitat, in the high 5-908 m above sea level in the lands. The analysis of kepundung phytocemical contents of phenol compound flavanoid, tannin, saponine and steroids. The secondary metabolic content which are found in the leaves are flavanoid, tannin, saponin and steroids, in the fruit seed are found flavanoid, tannin, saponin,steroids, in the pulp and in the bark are founf tannin, saponin and steroids where as in the fruit leather are only found saponin, steroids compound.
