Morphological Response of Takka Plant (Tacca leontopetaloides L.) as Traditional Medicine for Drought Stress

Abstract

Alternative medicine using herbs has been very popular in Indonesia in the last few decades. Takka plants contain secondary metabolite compounds that can be used as medicinal materials, it is necessary to administer drought stress. The purpose of this study is to study the morphological response of the takka plant (Tacca leontopetalooides L.) as a traditional medicine against drought stress. This research was carried out in the pilot garden of the Faculty of Agriculture, Khairun University, Ternate. It took place from June to April 2018. It was arranged in a split-plot using RAK with two factors and three replications, namely the first factor, genotype as the main plot, consisting of three populations namely G1: Gorango, G2: Gurua, G3: Bebsili. The second factor, media water content as subplots, which consists of four levels, namely K1: MWC 100%, K2: 75%, K3: 50%, K4 25%. Data were analyzed using the formula: Yijk = μ + ρk + αi + βj + (αβ) ij + Υik + εijk. The results showed that the treatment of drought stress at 100% and 75% water content had a significant effect on plant height, dry leaf weight, stem diameter, fresh tuber weight, dry tuber weight, tuber diameter. The treatment of drought stress at 25% media moisture content had a significant effect on the number of tubers and the number of shoots (23.6%).

Growth and Physiological Study of Gamma-Induced M4 Black Rice in Stress Condition

“…Shorttrunked plants are expected to be able to produce a large number of tillers to produce more grain. According to Syafi [13] black rice is a variety with a high plant posture, so it is very easy to fall. The gamma-ray irradiation treatment in this study was to improve the falling characteristics of rice plants, namely by creating rice plants with shorter stems.…”
