Experiment and application of a new method for sealing steeped jar with paraffin wax

This paper is an attempt to outline process and principle of a new method for sealing steeped specimen jar with paraffin wax.This method involved use of melted paraffin wax to pour it around the internal sides of the steeped specimen jar neck for sealing purpose.Four plant specimens,viz.,potato tubers with potato ring rot;rice stems and leaves with rice blast;branches,leaves and young fruits of citrus with citrus canker;and peppers with pepper anthracnose,were used in this experiment.Three different methods for sealing specimen jars with paraffin wax in which the four plant specimens were preserved,were designed in this experiment.The results showed that the method using the melted paraffin wax to pour it around the internal sides of the steeped specimen jar neck for sealing purpose,preserved the four plant specimens for the longest time compared with the other two methods.The advantages and disadvantages of this method and its usage and application have also been discussed in this paper.
