Morphological Characteristics of Wild orange Discovered in Khanh Hoa Province

Abstract

This study described the plant morphology of Wild Orange discovered in Khanh Hoa province. The description of plant morphology was based on IPGRI (1999) descriptors for Citrus spp. by describing tree characteristics; Collect 30 samples of leaves and flowers, 10 samples of ripe fruit; Molecular genetic analysis (gene); Analysis of essential oil content in leaves and fruit peels of Wild Orange trees. The results showed that the Khanh Hoa forest orange tree has the scientific name Citrus hystrix DC., the same name Citrus macroptera Montrouz. and has a common Vietnamese name of Chuc, is a highly adaptable species, has good resistance to external conditions and has a very high essential oil value, an average of 2.3% in leaves and 6.8% in oil. pods, but the number of individuals in the wild is very small. The research results provide scientific data for the evaluation, storage, conservation, and effective exploitation of wild orange genetic resources.
