Studies on the Relationship between Peroxidase Activity and Germination of Pinus koraiensis Seeds and on Metabolic Inhibitors in the Seeds

Zhang Liang-cheng, Guo Wei-ming and Chen Yong-sheng   

Abstract: The effect of both stratificating and decoating on germination and peroxidase activity of Pinus koraiensis seeds suggest that some role might be played by peroxidase in seed dormancy. Crude extract of seed are strongly inhibiting peroxidase activity and respiration in addition to hindering seed germination. Paper and thin layer chromatographic analyses have provided evidence that these activities are not attributable to the substance present in extracts which can inhibit germination. Experimental data reveal the presence of at least two kinds of peroxidases with different stability and different effects on the time course of peroxidase reaction. The inhibition on isoperoxidases and peroxidases are different from different biological sources.
