Study of soybean germination indices under salt stress with ascorbic acid pretreatment

Salinity is one of the most important factors limit economic exploitation of the land for agricultural crops. Benefits of the seed preparation are included enhancing the plant resistance at salt and drought areas, increasing the seed yield with low viability, breaking dormancy and also increasing crop. Ascorbic acid is one of the most important herbal antioxidant which plays an important role in processes such as cell growth and cell division, metabolism reactions at the time of germination; remove cellular toxicity, cell protection of oxidative reactions and preventing cell death. The results showed that the salt causes to reduce the growth of germination components. On the other hand the interaction between ascorbic acid and salinity on seed germination, rootlet dry weight, shoot length, uniformity of germination and germination rate is significant at the 1% level. But it was observed no significant effect on shoot dry weight and rootlet length. The results of mean comparison at different levels of ascorbic acid showed that the increasing of ascorbic acid increased the germination of soybean and improvement of germination elements at salinity.
