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

Abstract

Crocidolomia pavonana (Fabricius) merupakan hama penting pada tanaman brassicaceae yang menyebabkan kerusakan serius. Penelitian ini bertujuan untuk mengetahui aspek perkembangan dan reproduksi C. pavonana pada tanaman kubis dan caisim menggunakan analisis tabel kehidupan. Larva C. pavonana dipelihara secara individual dengan pakan kubis dan caisim, dan dilakukan pengamatan terhadap perkembangan, kelangsungan hidup, fekunditas, serta parameter populasi. Hasil penelitian menunjukkan bahwa pakan caisim menghasilkan waktu perkembangan yang lebih singkat, bobot pupa lebih tinggi, serta laju pertumbuhan populasi yang lebih cepat dibandingkan dengan kubis. Nilai laju reproduksi bersih (R₀), laju reproduksi kotor (GRR), laju pertambahan intrinsik (r), rataan masa generasi (T), dan waktu populasi berlipat ganda (DT) menunjukkan bahwa caisim merupakan pakan yang lebih mendukung potensi pertumbuhan populasi C. pavonana. Informasi ini menjadi dasar penting dalam pengembangan strategi pengendalian hama berbasis ekologi, khususnya dalam pemilihan varietas tanaman atau pengaturan pola tanam dalam sistem pertanian berkelanjutan.
