Abstract

Photosynthesis is the process of preparing organic substances H2O and CO2 into complex organic compounds that require light. Photosynthesis can only occur in plants that have chlorophyll, a pigment that functions as a catcher of sunlight energy which will later be converted into amylum. Amylum as a complex carbohydrate resulting from photosynthesis, plays an important role in various important physiological processes in the leaves. The purpose of this study was to determine the amylum content in tomato (Solanum lycopersicum) leaves. Qualitative descriptive method was carried out by referring to Sach's method by measuring the starch content of leaves using foil and betadine (Iodine) on tomato leaf samples. The results showed the presence of amylum in tomato leaves that were not covered with aluminum foil after being tested with Iodine solution. This is evidenced by the change in leaf color to blue-black on the surface of the leaves. While in tomato leaves covered with aluminum foil the color of the leaves turns pale and there are only a few blue-black spots, this indicates that leaves that are not exposed to direct sunlight and do not undergo photosynthesis normally have little amylum content in them. Keywords: Amylum, Solanum lycopersicum, Sach Test

Abstract

The tomato plant (Solanum lycopersicum) is native to the Americas, from the area around Mexico to Peru. Tomato stems, although not as hard as perennial plants, are quite strong. The color of the stem is green and is rectangular to round. The research method as well as analyzing the structure of tomato stems using descriptive methods. The research is descriptive analysis. Sampling was carried out at 16.00 WIB and only used one sample of tomato plant species and then made observations using a microscope with the help of section preparations. The data analysis technique used is a qualitative descriptive analysis model, where the model is included in the type of qualitative research described descriptively. The results showed that young tomato (Solanum lycopersicum) stems observed through a microscope with a magnification of 10x can be seen that only the epidermis, the cortex area (without being able to distinguish the tissue contained in the area), the transport tissue (without being able to know the location of xylem, phloem and other tissues) and the pith area where in this area the perenkim tissue is clearly visible.  Keywords:  Stem Anatomy, Solanum lycopersicum, Plant Tissue
