Karakterisasi Morfofisiologi dan Hasil Minyak 10 Genotip Nilam (Pogostemon cablin Benth.)

Abstract

Characterization of morphophysiology and oil yield of 10 patchouli genotypes (Pogostemon cablin Benth.) aims to test the morphology and physiology character of nine genotypes Aceh patchouli and one comparative clone (Lhokseumawe), obtain high yield oil clones (weight plant and essential oil content), and obtain genetic and phenotypic variabilities that can be used as a new genotype selection indicators. The research was conducted at Experimental Field and Plant Laboratory of the State Polytechnic of Lampung in April until November 2016. This research used Randomized Block Design (RBD) with 10 treatment levels and 3 replications.The LSI test results on the physiological character of the nine genotypes and one comparative clone showed that NPL 9 genotypes superior to the variables of the angle of petiole, chlorophyll content, leaf area, specific leaf area, and leaf area index. The NPL 9 genotypes resulted higher yield and rendement yields than other genotypes tested and one comparator, that was 2,36%. The character of stem production and rendement has a genetic variant value greater than the environmental variant. For genetic variability and phenotypic variability in the variables observed relatively uniform so that can not be used as an indicator of selection. Keywords: Aceh patchouli, leaf character, selection indicator, variability of genotype, variability of phenotype

Variabilitas, Korelasi, dan Analisis Kelas Sepuluh Genotipe Nilam (Pogostemon cablin Benth.)

“…Dengan demikian perlu dilakukan upaya untuk menghasilkan klon unggul baru yang memenuhi standar kualitas dan kuantitas nasional. Saat ini telah terdapat sembilan genotipe unggul hasil mutasi (Wulansari et al 2018) yang memiliki tampilan fenotipe, fisiologi, dan kualitas yang baik (Tahir et al 2019). Untuk memenuhi standar kualitas dan kuantitas nasional dilakukan pengujian multilokasi melalui uji BUSS (baik, unggul, seragam, dan stabil) pada berbagai lingkungan yang berbeda (Khadijah, 2012).…”

“…Penelitian dilaksanakan di lokasi Rajabasa Lampung Selatan pada bulan April 2020-Januari 2021. Bahan tanam merupakan sembilan klon tanaman nilam generasi MV6 yang telah diseleksi sejak tahun 2018 (Wulansari et al 2018) hingga 2019 (Tahir et al 2019).…”
