The relationship between the chloroplast of the whea t seedling and Ca 2+ under water stress was examined with the cytochemical method of the improved calcium antimonate precipitation.The results obtained sho wed that there was a little calicum in chloroplast; with the longer the duration of water stress the higher the free in chloroplast and the more s erious the injure of ultrastructure of the chloroplast; after rewatering, the fr eein chloroplast decreased and ultrastructure of chloroplast resum es normal again.
