Abstract: Changes caused by salinity and glycerol or aspartic acid on growth, oil contents, endogenous glycerol and recinine alkaloids of Ricinus communis plant have been studied. Growth, oil contents and recinine alkaloids in roots of Ricinus communis plant were significantly lowered with the salinization effect using NaCl. On other hand, oil contents and recinine alkaloids in shoots were increased. However, endogenous glycerol in shoots and roots increased with increasing salinization level. Growth, oil contents, recinine alkaloids and endogenous glycerol in the different organs of plant originating from seeds soaked in glycerol or aspartic acid were generally increased over the control. However, recinine alkaloids in roots decreased. Soaking seeds in glycerol or aspartic acid counteracted the adverse effect of salinity on growth and secondary products of Ricinus communis L. Plant.
