Identifikasi Karakter Fenotip Daun Tanaman Aren (Arenga pinnata Merr) di Kabupaten Tapanuli Selatan

Abstract

Identification Phenotypic Character of the Leaves Palm Plant in South Tapanuli Regency This study
aims to determine the effect of the phenotype character of palm leaf leaves on the production of roomie
in wild populations of natural habitats in South Tapanuli Regency. The study was conducted in five
villages in each oft he four sub-districts in the South Tapanuli district. Two hundred sugar palm plants
originating from four natural habitats have been identified in accordance with plant identification
procedures issued by the IPGRI (International Plant Genetic Resources Institute, 1995) and analyzed.
The results show that 4 clusters were formed with 75% similarity or 25% diversity. These results can
be concluded that cluster 1 is the population of palm plants that have the long character of petiole
and the highest number of unproductive leaves. Whereas the characters of leaf length and rachis length
are still lower than the population of sugar palm plants in cluster 4. Cluster 2 is the population of sugar
palm plants that has the highest character of sap production per day. Cluster 3 is a population of
palm plants that have the highest leaf width character. Cluster 4 is a population of palm plants that
have the highest leaf length and rachis length with the highest number of leaflets and the largest rachis
circumference and petiole circumference. The number of productive leaves and the percentage of sap
sugar content above average.
