Respons Perkecambahan Benih Kopsia (Kopsia Arborea Blume) pada Tingkat Kematangan Buah Yangberbeda dan Aplikasi Rizobakteri

Abstract

Kopsia plants are known secondary metabolites. While extensive research has been conducted on the secondary metabolites of kopsia, studies on its cultivation and propagation techniques remain limited. This study aims to analyze the effects of fruit maturity level and rhizobacteria application on kopsia seed germination. The treatment tested in this study included different fruit maturity levels (immature, semi-mature, and mature) and rhizobacteria application (0% and 5%). All mature fruits germinated successfully (68%), whereas immature and semi-mature fruits showed no germination at all (0%). The absence of germination in immature and semi-mature fuirts was due to the physiologically immature embryos. Rhizobacteria were found to accelerate seed germination in mature fruits, and the resulting kopsia seedlings exhibited better growth. Overall, kopsia seed germination occurred only in mature fruits. Rhizobacteria application helped balance shoot and root development.
