초록

Germination characteristics and alterations in soluble sugar-starch transition and phytic acid during germination were studied in rice seeds under saline conditions. NaCl significantly reduced the speed of germination. Also, the radicle growth out of seeds was severely inhibited by the exposure to NaCl solution, thus, seeds were almost impossible to grow to seedlings. Soluble sugar was remarkably accumulated, whereas starch was decomposed stepwise during seed germination. The metabolism of soluble sugar and starch in germinating seeds showed a distinct difference. The level of phytic acid in seeds decreased in all NaCl treatments during germination, but the level was affected differently by NaCl concentration in the two varieties. Overall, our results suggest that salt stress retard the radicle growth of rice seeds, and affect the starch-to-sugar conversion and the decomposition of phytic acid differently in two varieties.
