The objective of this study was to establish the effective use of spot test for early selection of perilla mutants which have low α-linolenic acid in seed oil. The average α-linolenic acid content with 30 accessions determined by GLC was 57.9% and the contents ranged from 51.4 to 65.6%. The results of spot test, red colour is related to high α-linolenic acid content in perilla whereas yellow colour indicates absence of α-linolenic acid. The colour density by an image analysis was highest in perilla among oil crops tested. The correlation coefficient between colour density by spot test and α-linolenic acid content determined by GLC was highly significant. Therefore, the spot test was considered useful as a preliminary screening method for the relative α-linolenic acid content in mutation breeding.

This paper presents a high sensitive force sensing module to measure machining forces for a tip-based nanopatterning instrument. The force sensing module utilizing a leaf spring mechanism and a capacitive displacement sensor has been designed to provide a measuring range from 80μN to 8N. This force sensing module is mounted on a PZT driven in-feed motion stage with 1 ㎚ resolution. The sample can be moved by a X-Y scanning motion stage with 5 ㎚ resolution. In the patterning experiments, the machining forces were controlled and monitored by the force sensing module. Then, the patterned sample was measured by AFM. Experimental results demonstrated that the developed force sensing module can be used as an effective sensing device in the nanopatterning operation.
