Abstract

Bali salak cultivars (Salacca zalacca var. amboinensis) (Arecaceae) commonly grow in Bali and other areas of the Indonesian archipelago and are of considerable value as a trade commodity because of their edible fruits. The thirteen cultivars that are currently recognised in Bali are distinguished from each other on the basis of fruit colour and taste. The research reported in this thesis documents the variability in Bali salak cultivars and provides a method for their reliable identification prior to fruiting. This involved analysis of vegetative anatomical and morphological characters as well as reproductive characters of all 13 cultivars.

Analysis of variance (ANOVA) was used to analyse the quantitative features to determine which characters differed significantly between cultivars. Multivariate techniques of cluster analysis and multidimensional scaling (MDS) were used to delimit and test groups of cultivars. Means for 17 of the 42 quantitative characters differed significantly (p≤0.05) and nine of the qualitative characters showed distinct variation between the cultivars. Cluster analysis of quantitative and qualitative characters established that the 13 cultivars grouped into four distinct clusters. MDS indicated that plant height, leaf length, middle leaflet length, female flower length, adaxial cell length, periclinal cell wall pattern, flesh taste, presence of fruits and seeds, which had square correlation values of more than 0.7, are reliable discriminators of cultivars. This study showed that anatomical and morphological characters and reproductive characters can be used as diagnostic tools to identify the 13 Bali salak cultivars. However, based on the multivariate analysis, it is proposed that this 13 be reduced to eight. The eight cultivars recognised in this study are Muani, Bingin, Putih, Nyuh, Maong, Boni, Gula and Biasa. Keys and descriptions of each cultivar are provided and recommendations are made for future research in Salacca zalacca var. amboinensis.
