| Outline of Final Research Achievements |
Authors had been studying to know water content in leaves as the biological information, so far we have developed ‘water stress indicator sheet’ using cobalt chloride for simple estimation of water status (Morinaga et.al. 2012, 2016). Now, we are trying to understand water contents in leaves as electrical method with plants.
Electrostatic capacitance and electro-cycle length were measured using an instrument that we developed, and checked the relationship with transpiration rate by leaf porometer. As a result, the electrostatic capacitance has not clear correlation with transpiration rate because it is too sensitive against electronic noise such as contact, oscillation or length of electronic cord. On the contrary, electro-cycle length had stably good relationship with transpiration rate. It is possible to estimate water status of plants leaves by measuring electro-cycle length.
