Photoselective Nets Alter Apple Canopy Air Temperature and Carbon Translocation during Dormancy and Budbreak

Photoselective nets were used to examine apple shoot physiology during dormancy and budbreak. Two trials conducted: one in the field controlled conditions. In first, three colored (red, blue, white, shading 20%) covered sections of single trees, leaving an empty portion as control, from December April. The white net increased canopy air temperature compared with blue one. Differences found carbohydrate seasonal patterns; however, it appeared that soil had higher impacts on sugar movement trees. No differences bud phenology. second trial, cuttings placed boxes constructed same-colored monitored end February Results showed phenology translocation. box hastened bloom its amounts carbohydrates at trial. On contrary, delayed while resources still being consumed lowest reserves These results add new insights under different light spectra commercial applications should not be excluded for improving crop management.
