Full text linkSoybean (Glycine max (L.) Merr.) is a plant that requires full light intensity, but both excessively high and low light intensities can influence its growth, both morphologically and anatomically. This research aims to determine the morphological and anatomical characteristics of soybean plant’s roots, stems, and leaves subjected to different light intensity treatments. The research employed a descriptive method with the following treatments: P0: low light intensity (130,000 lux). Direct morphological observations were conducted directly, while anatomical observations were carried out by preparing specimens using the embedding method. The results of the study on the morphological characteristics of soybean plants under low light intensity treatment showed the tallest plant height, in contrast, moderate light intensity treatment exhibited wider leaf area, and the high light intensity treatment had a higher leaf count and longer root length. The anatomical features of soybean under low light intensity treatment included thinner leaf, stem, and root tissues, while the moderate light intensity treatment showed a larger stomatal area, higher stomatal density, and thicker root tissues. Meanwhile, the high light intensity treatment displayed thicker leaf and stem tissues compared to the other treatments. In conclusion, based on the research findings, moderate and high light intensities resulted in more favorable outcomes compared to the low light intensity treatment
