The effects of seedcoats of high- and low-tannin sericea lespedeza on seed germination were studied. Seedcoat water extracts of both high- and low-tannin sericea lines reduced germination and radicle elongation of sericea seed. Removal of seedcoats Increased germination of both lines when germinated with water. Seedcoats of seed from high-tannin plants inhibited germination to a greater extent than those from low-tannin plants. A seedcoat inhibitor may be a factor in slow germination of sericea. The high seedcoat tannin content of both sericea lines shows that germination inhibition is caused by a substance other than tannin.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
