Handheld Device for non-invasive Leaf Analysis
The following data demonstrate how the LSA-2050 reveals differences in leaf acclimation between field-grown and greenhouse-grown plants. Four-week-old bean seedlings (Phaseolus vulgaris cv. Saxa) were measured on upper and lower leaf sides under both growing conditions. he visible light intensity in the greenhouse was about one third of the field intensity, and UV radiation was virtually absent. The results show clear differences in UV screening efficiency, chlorophyll content, and FV/FM. This illustrates how the LSA-2050 captures the physiological fingerprint of light acclimation in a single, non-invasive measurement.
UV-B screening (Apparent Transmittance at 310 nm). Upper and lower leaf sides were investigated (see x-axis labels). Mean values of four plants per treatment are shown (error bars show 95% confidence intervals). UV-B screening was most efficient (10%) on the upper side of field-grown leaves.
