Abstract

Traditionally, the inhibition of sprouting in potatoes (Solanum tuberosum L.) during storage is carried out with the application of carbamates (chlorpropham), also known as CIPC. These products are very effective in controlling sprouting, but their application has raised questions both from an environmental point of view and from human health (carcinogens). As a result, many countries have banned the use of the CIPC for this purpose. The beginning of the sprouting process in potato tubers is related to the end of endo-dormancy, which is affected by environmental and physiological factors. Among these environmental factors, light plays a fundamental role in the elongation of potato sprouts, especially at wavelengths close to red-far red (700-730 nm) and blue (400 and 450 nm). However, no results were found using a Light-Emitting Diode (LED) to inhibit sprouting. Thus, the hypothesis of this study is that the use of LEDs in the region of red/far red and blue will inhibit the sprouting of potato tubers stored for long periods. For this, 'Asterix' potatoes will be harvested and used in several experiments, aiming to: I) determine the best light quality (red, far red or blue) for controlling sprouting compared to CIPC application; II) determine the percentage of surface area to be exposed to light (100%, 50%, 25% and 10% of the tuber) that leads to sprout control, and III) determine the duration of exposure to light (short or long) for effective sprout control compared to CIPC application.
