Relationship among Agroclimatic Variables, Soil and Leaves Nutrient Status with the Yield and Main Composition of Kaffir Lime (Citrus hystrix DC) Leaves Essential Oil

Abstract

Previous studies revealed the impact growing location has on the quantity and quality of essential oils derived from numerous Citrus spp., except on the kaffir lime. This study aims to analyze the relationship shared by agroclimatic variables and soil-plant nutrient status to kaffir lime leaves essential oil yield and main composition. The experiment was conducted between February and April 2019 in four growing locations, namely Bogor (6°36′36″ S, 106°46′47″ E), West Bandung (6°48′12″ S, 107°39′16″ E), Pasuruan (7°45′5″ S, 112°40′6″ E) and Tulungagung (8°6′27″ S, 112°0′35″ E). The highest essential oil yield was obtained from Bogor (1.5%), while the lowest one was from Tulungagung (0.78%). The yield was positively and significantly correlated with the rainfall, soil organic carbon, soil pH, and macronutrient levels, i.e., nitrogen, phosphorus, and magnesium. Citronellal, the major component in metabolites’ profile of kaffir lime leaves essential oils, was significantly affected by the growing location. The absolute content of citronellal was positively and significantly correlated with the actual soil pH and leaf Ca content; furthermore, it negatively correlated with the leaf content of Fe, Mn, Zn, Cu. Pearson correlation analysis also showed (i) a negative significant correlation between the relative percentage of citronellol and annual rainfall intensity; (ii) a negative significant correlation between altitude and relative percentage of caryophyllene, and (iii) a positive significant correlation between the relative percentage of linalool and leaf K content.

Variation in Flavonoid Compounds, Volatiles and Yield Related Traits in Different Iranian Rosa damascena Mill. Cultivars Based on SPME Arrow and LC-MS/MS

“…However, a previous report on Citrus hystrix revealed that citronellol has a negative correlation with rainfall intensity [ 33 ]. Although a high variation was reported within individual flavonoid groups in response to elevational changes, it can be suggested that long days with cool night temperatures are the most crucial one for the biosynthesis of flavonoids [ 34 ].…”

Potensi Aromaterapi Jeruk Purut (Citrus hystrix DC.) sebagai Adultisida terhadap Aedes aegypti (Linn.) Dewasa

“…31 Perbedaan kandungan senyawa dalam minyak atsiri pada berbagai penelitian dapat dipengaruhi oleh metode ekstraksi yang digunakan. 31 Ragam kandungan senyawa dalam jeruk purut juga berhubungan dengan kondisi dimana jeruk purut ditanam, seperti kandungan sitronela akan tergantung pada pH tanah, sedangkan kandungan senyawa linalool berhubungan dengan ion K. 32 Efek insektisida pada nyamuk dewasa yang ditunjukkan dalam penelitian ini dapat menambah referensi mengenai pemanfaatan minyak atsiri jeruk purut dalam sediaan aromaterapi diffuser. Efek insektisida minyak atsiri jeruk purut terhadap serangga dengan berbagai bentuk sediaan juga telah banyak dilaporkan.…”

Short Communication: Agronomical characteristics of sweet corn under different plant growth regulators during the dry season

“…Leaf was an important variable to be an appropriate proxy of plant growth (Salazar et al 2018;Hamdani et al 2022), morphological feature (Efendi and Budiarto 2022;Budiarto et al 2021a;2021b;Djarot et al 2021), phytochemical content (Efendi et al 2021), and physiological condition (Budiarto et al 2018;Budiarto et al 2019b). Leaf size, in terms of leaf length and width, of sweet corn at present proved to be significantly affected by the application of PGR.In theory, the application of GA3 was able to increase leaf length by increasing plant cell division and elongation, but higher doses of gibberellic acid inhibited leaf growth yielding shorter leaves (De Souza and MacAdam 2001; Utami et al 2018).…”
