FI-SM (7-45 mm)
The FI-SM Sensor enables to monitor growth of large size fruits as well as variations of their diameter in submillimeter range. Two phenomena affect diurnal behavior of fruit diameter: growth and water balance of a plant. A growth component is dominant in most of cases. However, some fruits may loose water or decelerate their growth at daytime in water stress conditions. Two features of the daily fruit growth curve are to be noted: a diurnal form and daily maximums trend that is growth rate.
