Various methods have been tried to measure plant growth and swelling. For example, a rule has been used to measure plant elongation and calipers to measure fruit swelling. Recently, many electrical sensors such as differential transformer have been tried in order to use computer for data logging and analysis.
In this report, the non-destructive and continuous measurements are described as following. The measured data will be reported in the following paper.
(1) Measurement of shoot elongation,
(2) Measurement of fruit swelling,
(3) Measurement of leaf development,
(4) Measurement of flower bud swelling.
