Effects of SAP coatings on seed germination of C. korshinskii

Seed germination (a), germination energy (b), germination index (c), and vigor index (d) in seeds with different coatings. Germination (%) and germination energy (%) were the percentages of germinated seeds three and seven days after imbibition, respectively. CK1 and CK2 represent naked seeds and seeds coated with clay and talcum powder, respectively. Groups A, B, C, D, and E represent seeds coated with corresponding SAP. The data are expressed as mean±SD from three replicates. Different superscript letters indicate significant difference at the P<0.05 level
