Ecological factors and morphological traits of Coffea Liberia Hiern in Kalipuro District, Banyuwangi Regency

Abstract

This study aimed to analyze the ecological factors and morphological traits of Liberica coffee in Kalipuro District, Banyuwangi Regency. Ecological and morphological factors were measured, and observations were recorded accordingly. The observation of significant morphological characters has been thoroughly conducted The observed ecological factors were microclimate factors, including altitude, air temperature, humidity, light intensity, rainfall rate, soil pH, soil temperature, and soil moisture. The Paleontological Statistics (PAST) program was used to perform multivariate analysis to group liberica coffee variants based on morphological traits and physical factors of the plantation. The study found that physical environmental factors had a relatively significant influence on morphological variation in each population. The light intensity and relative humidity were the physical environmental factors related to morphological traits, such as leaf shape index, number of flowers per inflorescence, and leaf surface index based on principal component analysis (PCA). Unstable weather conditions can influence environmental factors, which, in turn, can profoundly impact morphological characteristics, specifically the flowering season. The study revealed a statistically significant correlation between light intensity and the number of flowers per inflorescence.
