| The objective of this research was to determine the effect of seed priming on membrane integrity during poriming and germination. Among the five chemicals, $KNO_3$at 150 mL gave the shortest $T_{50}$ (days required to reach 50% of the final germination percentage). Compared to unprimed, the seeds primed with 150 mL $KNO_3$ at 20$^{circ}C$ for 4 days had reduced $T_{50}$ values when germinated at 15$^{circ}C$. These results indicated that seed priming is an effective way for rapid and synchronized germination, especially at low temperature. Changes in conductivity of priming solutions during the 4-days period of priming were highly dependent upon the priming agents. Conductivity of the $KNO_3$ and $K_3PO_4$ solution slowly declined during the first 3 hours ad then increased Amount of amino acids, sugars and proteins exuded from seeds into $KNO_3$ solution were less than those into distilled water and $K_3PO_4$. All the results suggested that the $KNO_3$ priming play a positive role in regulating the permeability of cell membranes. |
