The increasing soil salinity becomes one of the major environmental limiting factors that affects growth and productivity of rice(Oryza sativa L.).In view of previous report that silicon can alleviate salt injury in rice seedlings,we observed the performance of rice seedlings(Oryza sativa L.cv.Nipponbare)under salt stress with silicon treatment,the morphological observations showed that silicon treated seedlings performed better than plants with no silicon treatment,silicon treatment indeed can retard the rice leaves injury.
