Abstract

This study aims to determine whether the extract of mint leaves (Mentha piperita L.) is allelopathic towards germination and growth of upland rice varieties of Inpago 8. This research was conducted from November to December 2018 at the Botanical Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung. This study used a Completely Randomized Design (CRD) consisting of 5 levels of concentration (0% b / v (control), 10% b / v, 20% b / v, 30% b / v, 40% b / v) which consists of 5 replications. As parameters are germination, shoot length, fresh weight, root shoot ratio, relative water content, chlorophyll b ratio to a. F test and t test were carried out at the 5% significant level. The results showed that the concentration of 20% reduced germination percentage to 78% while the concentrations of 30% and 40% inhibited totally the germination of rice seeds. The extract concentration of 10% and 20% inhibited the growth of the length of shoot and the fresh weight of seedling.The root shoot ratio and relative water content were constant in all treatments. The ratio of chlorophyll b to a did not experience a significant change in all treatments. From the results, it was concluded that the extract of dried mint leaves was allelopathic towards upland rice seedling, varieties of Inpago 8 .
