Citation analysis was applied to the data of the Journal Plant and Cell Physiology of the year 1998. The distribution of citation frequencies was statistically tested and found be negative exponential distribution type. The obsolescence factors were determined. The average half-life literature was found to be of 6.2 years. Brooks technique of calculating AAF=a was applied to determine its applicability for the literature. The values of "a" was found to be 0.85 and the utility factors were calculated and found to be 6.64.
