“…For bulbs that were not exposed to UV light, the visual index of dormancy (VID) presented reduction with the increase of plastic film thickness ( Figure 2) The low level of oxygen in the environment reduces the cellular respiration, decreasing the energy supply necessary in order to occur the cellular division and, as a result, the sprouts growth (BRACKMANN et al, 2010). In this sense, the reduction of the VID in bulbs is related to the fact that the packing reduces the bulbs respiration, therefore reducing its metabolism, which resulted in a lower development of the shoots leaves.…”
