| Abstract: | In root tips of a salt-sensitive ecotype of Agrostis stolonifera,treatment with 100 mmol I–1 NaCl for two weeks resultedin conspicuous structural damage to mitochondria, which becamedeficient in cristae, swelled and vacuolated. A salt-tolerantecotype maintained normal root tip mitochondrial structure underthe same salt treatment, in spite of accumulating higher levelsof sodium and chloride in its roots. The subcellular distributionof chloride, as judged by electron microscopy after precipitationwith silver ions, was identical in both ecotypes. |
