Abstract
Photosynthate translocation from leaves to fruits is an important determinant of crop yield and quality. In protected cultivation, environmental control based on photosynthate translocation is indicative for realising high-yield and high-quality production. There are, however, few studies on the environmental response of photosynthate translocation, especially during twilight. In greenhouses, these transition periods are charac-terised by a drastic change in relative humidity (RH). In this study, we focused on light intensity as a key environmental factor to steer translocation under high RH prevailing under twilight conditions. We fed (CO2)-C-11 to a leaf of strawberry plants (Fragaria x ananassa Duch.) and analysed real-time dynamics of C-11-labeled photo-synthate translocation to individual fruits on an inflorescence of intact plants by using positron emission to-mography (PET) under different light intensities (i.e., 50, 200 and 400 mu mol m(-2) s(-1)). No clear relationship was obtained between 11C-photosynthate translocation and light intensity since the results revealed that trans-location rates into the fruits were highest under the light intensity of 200 mu mol m(-2) s(-1) followed by those of 400 and 50 mu mol m(-2) s(-1). However, there was a strong negative correlation between transpiration rate of the C-11-fed leaf and C-11-photosynthate translocation rate. These novel findings indicate that transpiration, which controls leaf moisture status, is one of the drivers for photosynthate translocation towards fruits during twilight conditions.
