主 题：Phenotyping Structure Heterogeneity Model calibration Azimuth Elevation
摘 要：Accurate structural phenotyping analysis is essential to understand plant architectural adaptation strategy to environment *** aim of this study was to analyze leaf arrangement and geometry influenced by azimuthally generated light gradient;and to simulate static and heterogeneous cucumber canopies using regression equations by considering more geometric *** continuous measurements of structural organ parameters were obtained to fit the organ initiation and expansion *** measurements with three density treatments were obtained to validate model *** describe leaf distribution and orientation characteristics in more detail,azimuth and elevation models were introduced into canopy structure *** distribution frequency was simulated based on leaf area index and solar elevation angle while leaf elevation was simulated based on leaf azimuth and acropetal phytomer *** study provides an important basis for structural phenotyping analysis of cucumber canopy,which is essential for more accurate functional-structural modelling in the future.
