Study on relationship between pollen exine ornamentation pattern and germplasm evolution in flowering crabapple.

ABSTRACT: Pollen ornamentation patterns are important in the study of plant genetic evolution and systematic taxonomy. However, they are normally difficult to quantify. Based on observations of pollen exine ornamentation characteristics of 128 flowering crabapple germplasms (44 natural species and 84 varieties), three qualitative variables with binary properties (X_i: regularity of pollen exine ornamentation; Y_i: scope of ornamentation arrangement regularity; Z_i: ornamentation arrangement patterns) were extracted to establish a binary three-dimensional data matrix (X_i Y_i Z_i) and the matrix data were converted to decimal data through weight assignment, which facilitated the unification of qualitative analysis and quantitative analysis.
