Modeling Cucumber leaf orientation as growing in heterogeneous
Keywords: LAI, Leaf azimuth, sunlight greenhouse, cucumber, heterogenesis
AbstractThe objective of this work is to analyze the changes of leaf azimuth during cucumber growth and describe the relationship between light environment and leaf azimuth character using a simplified model. Five plant density treatments were conducted in autumn 2012. Eight neighboring plants per treatment were selected to measure leaf azimuth, leaf length and leaf width at four times. LAI was considered as indication of light intensity to analyze the relationship between light environment and leaf azimuth character. Linear function was used to describe the relationship between LAI and leaf distribution frequency in different leaf orientation classes. Leaf distribution frequency changed as the influence of heterogeneous light conditions. The leaf distribution frequency in the north direction decreased as LAI increased while opposite situation has been found the south direction.
