Karakterisasi Morfologi Tanaman Jeruk Siam (Citrus Nobilis) di Kabupaten Karo

Abstract

ALBERT OREN HARIANJA: Morphological Characterization of Siamese Orange Plants (Citrus nobilis) in Karo Regency supervised by Ir. Revandy Iskandar Muda Damanik, M.Sc., M.Sc., Ph.D. This research aims to characterize and analyze the morphological variations of Siamese orange plants (Citrus nobilis) as well as the relationship between orange plants in three different locations in Karo Regency. The research was carried out using an exploratory survey method, involving collecting orange plant accessions at production centers in Kabanjahe, Tiga Panah and Merek. Direct observations in the field were carried out to identify local names, characteristics, characteristics and cultivation techniques applied. The kinship among Siam orange (Citrus nobilis) accessions in Karo Regency, analyzed based on a combination of qualitative data (plant form, leaves, fruits, skin color, flesh, and taste) and quantitative data (stem circumference, number of seeds, and segments), shows that at a rescaled distance of 0–5, a close grouping occurs. In this first cluster, the accessions KR1, MA3, MD2, TS3, MD1, MN1, MD3, MN2, TD1, TA3, TA2, KL2, KL1, TA1, KD3, TD2, MN3, TS2, KL3, KD2, MA2, KR2, MA1, and KD1 are grouped together. This indicates that these accessions still share relatively similar characteristics, despite originating from different locations.
