ABSTRACT

Thirty genetic stocks of sugarcane were analysed for sodium content. Differences in leaf
sodium content among clones as well as stages and their interaction were significant. The range
of leaf sodium content was from 0.288 % in Co 6806 to 0.430 % in Co 975. Clones Co 6806,
Co 7508, Co C 671, Co 7204, Co 7201, Co J 64, Co 617, Co 62174, Co 7717, Co 6304,
Co A 7601 and Co 853 had low sodium content. Sodium content in leaf increased from 0.290
at the 4th month to 0.451 at the 7th month. Leaf sodium content had significant positive
association with calcium, magnesium, chloride, sum of cations, sum of anions and negative
association with nitrogen and yield of cane and sugar. However, leaf sodium concentration had
no significant association with leaf phosphate, potassium, sulphate and silicon content at any of
the stage.
