Abstract: The objective of study was to analyze the Na- and Cl^- dynamic of the arecanut leaves from different yield levels, different growth years and the ones with yellow leaf disease. The leaves were collected from normal fruit-bearing arecanut in different production levels and different growth years and those of yellow leaf disease for the experimental materials. The results showed that the Na + content was high in leaves. The average Na + content was 1.9%. The Na⁺ content of the arecanut leaves had not a significant change, and which didn’t show a line trend with arecanut yield varying. The differences in Na + content between normal arecanut leaves and ones with yellow leaf disease was not significant. The Cl^- content of arecanut leaves decreased with yield declining, The Cl^- content of arecanut leaves in the middle- and low-yield groups decreased by about 30% and 45% than that in high-yield group, respectively. The Cl^- content of yellow leaf disease was 60% lower than that of high-yield group, and was 28% lower than that of low-yield group. Na⁺ content of Arecanut leaves decreased with the growth time. However, the Cl^- content of arecanut leaves had no significant change with growth time increasing. There was no significant difference between different grades in productions, Na⁺ declined along with arecanut growing time increasing. Arecanut leaves with the high yield have relatively high Cl^-, and Cl^- content of arecanut with yellow leaf disease was significantly lower than that of the normal arecanut, Cl^- content has not an obvious linear trend with the growing time.
