Abstract/Description
LAI as Affected by Flashing-Light Interception With
Corn (Zea mays) and Soybeans (Glycine max)
Corn (Zea mays) and Soybean (Glycine max) are both staple crops in global agriculture. With growing concern regarding food security and production, indoor cultivation of corn and soybean plants has become a question of interest. This study looks at the application of different lighting regimes for corn and soybeans and effects on development. Light that can be used by plants is called photosynthetically active radiation (PAR). PAR is the solar radiation range of energy that plants use for photosynthesis, these fall between the wavelengths of 400 to 700 nanometers (Wang, 2020). When growing plants indoors PAR becomes a limitation for development. The data for this experiment was collected every three days for two weeks during February 2023. Both corn and soybean plants were examined under three different lighting environments including white light, flashing light, and the control being natural light. These light regimes were enacted in a controlled environment and maintained at 68 to 70℉. Plant height and chlorophyll content data were collected for both the corn and soybeans as well as the germination timing on the soybeans. Analysis of variance (ANOVA) with LSD at 5% of significance was performed to analyze the data statistically. Significant differences were observed in the chlorophyll content of corn under white light and flashing light treatments. This is likely due to the corn plants' stomata not remaining open to accept carbon dioxide and water thus slowing growth (Qian, 2022). In addition, soybean emergence was highest under the white and flashing light treatments. The flashing light treatment also displayed both the highest chlorophyll measurements as well as general plant height. The data from this research will enhance the knowledge of crop growers on how important light intensity and light color is for corn and soybean production.
