                      measurement of transport and allocation of recently produced
                      photo-assimilates in plants, which are labeled with
                      $^{11}$C. We operate the plant dedicated system
                      <i>pheno</i>PET which consists of lutetium-yttrium
                      oxyorthosilicate crystals readout with digital Silicon

                      The horizontal Field-of-View (FOV) with a diameter of
                      180$\,$mm and a height of 200$\,$mm allows the measurements
                      of plants in their natural orientation. Raw data are
                      analyzed offline and reconstructed with Ordinary Poisson
                      Maximum Likelihood Expectation-Maximization (OP-MLEM)
                      provided by PET Reconstruction Software Toolkit (PRESTO). We
                      will present the implemented corrections to reconstruct
