Estimating Sink Parameters of Stochastic Functional ...

Functional-structural plant models (FSPMs) generally simulate plant development and growth at the level of individual organs (leaves, flowers, internodes, etc.). Parameters that are not directly measurable, such as the sink strength of organs, can be estimated inversely by fitting the weights of organs along an axis (organic series) with the corresponding model output.Plant morphological and functional characteristics ...Morphological and functional characteristics, as well as mound parameters, were summarized using principal component analysis (PCA). Pearson''s correlation analysis, linear regression analysis, and redundancy analysis were conducted to identify the relationships between plant characteristics and mound parameters.
