Effect of light intensity on the growth and production of rodent tuber (Thyponium flageliforme (Lodd.) Bl.)

Abstract

AbstractRodent tuber is a wild plant that has the potential as an anticancer drug. For this purpose, the availability of materials is necessary, it needs good cultivation to maintain its herbal quality, and light intensity is one of its components. Therefore, research is needed to obtain light intensity that can increase the growth and production of rodent tuber plants. Shading research on rodent plants was carried out in a screen house, ISMCRI, from January to December 2020. The study was arranged in randomized block design, five treatments, and 40 samples per treatment with five replications. The treatment that were given is several levels of light intensity : 100%, 65%, 50%, 35 %, and 25%. The number of leaves, chlorophyll content, fresh and dry biomass, fresh and dry weight tubers, nutrient content and nutrient uptake, protein content, and protein production are the parameters. The result showed light intensity significantly affected the number of leaves, fresh and dry weight tubers at eight months after planting. Plants that received 100% light intensity produced the highest growth and production of rodent tubers, while the lowest was 25% light intensity.
