Abstract

Sago palm has the highest starch content compared to the other source of carbohydrate crops such as cereal and tuberous crops. Sago palm can produce about 200-400 kg per trunk after 7 to 10 years. This research aimed to characterize several sago palm accessions in Aimas, Sorong District, West Papua Province, Indonesia. Eight sago palm accessions were studied, Waruwo, Wasulagi, Wasenan, Wayuluk, Wagelik, Wanegles, Wawun and Wafabala. Among these accessions, there were many diff erences based on trunk morphological characteristics which includes trunk height, diameter, circumference, and bark thickness, leaf number, length of rachis, length of petiole, and spine. Five accessions with potential yield of more than 200 kg dry starch per sago trunk are Waruwo, Wasulagi, Wasenan, Wayuluk and Wagelik. Stem morphological characters aff ect palm sago production, because the starch is located in the pith of the stem.

Abstract

Natural populations of sago (Metroxylon sagu) in Indonesia show morphological variations in its organs, particularly the leaves. The existing variations resulted in sago type names provided by the locals. The sago plant types include Mahang, Buntal, Salak, Madang and Gandut. Sago leaves are economically important in Indonesia, mainly because they provide a potentially profitable and environment-friendly source of house roofing materials. Determining leaf variation among sago plants would provide information for a better way of choosing which among the current accessions/varieties of sago has the best leaf quality and production. Leaf variations in sago were recorded in shape, size, and color. The aim of this study are a) to compare differences in leaf morphology among sago types obtained from different geographic areas, and b) to determine whether these different sago types correspond to certain sago plant grouping. The qualitative and quantitative analysis showed variations in leaf characteristics of sago trees. Additionally, this study shows that based on leaf variations, the sago of South Borneo Province can be separated into two groups. The first group is Mahang and Gandut, which have long rachis, leaflets and leaves, and largest leaf area. The second group composed of Buntal, Salak and Madang accessions, which have short rachis and leaves, and smallest leaf area. Other results showed that there were characters that contributed significantly to the diversity of sago plants in the study area including spines, white stripe or banding on the rachis and petiole length. In line with our results, Mahang and Gandut accessions are the best accessions to be cultivated in the area, because they have wider leaves which support higher rates of photosynthesis. Further study should be conducted on phylogenetic using DNA sequencing to confirm divisions of the two sago groups.
