Summary
Salt-stress effects were studied on vegetative growth and mineral and carbohydrate contents as well as on the activity of amylases, phosphorylase and invertase of two cotton varieties, Dandara and the more salt-tolerant Giza 45.
Stress reduced growth and increased leaf chloride more in Dandara; it increased leaf cations more in Giza 45. It tended to increase sugar and, to a smaller extent, starch in leaves of both varieties. Sucrose was negatively correlated to invertase activity. Amylolytic activity showed little change, while the marked rise of phosphorylase activity in both varieties was of no correlation with the starch content.
It is suggested that different ion regulation in combination with carbohydrate metabolism contribute to salt tolerance of cotton varieties.
