, transport of photoassimilates from source tissues via the phloem to sink tissues, and stress tolerance ( Doman and Geiger, 1979 ; Marschner, 1995 ; Pettigrew, 2008 ; Usherwood, 1985 ). Deficiencies of K are associated with a number of economically

(2005) posit that the lack of a direct causal relationship between the source-to-sink ratio and accumulation of TSS makes this difficult to assess and forecast. Indeed, we did not find a difference on basic fruit chemistry at harvest in the 2 years and

causality. It is possible that inherently low vigor reduces growth and sink demand for vegetation, leaving more sources available for fruit set and reproductive growth. In fact, many studies show that reducing vigor, by dwarfing rootstock ( Avery, 1970

evaluated citations in the “Photosynthesis—Source–Sink Physiology” subsection of the Journal of the American Society of Horticultural Science for 2003 and 2004, we found that all of the published papers had per-leaf-area expressions in tables or figures

latter gives erratic results and is not efficient when pollination from a specific pollen source is desired. Hand pollination improves fruit set and substantially boosts fruit yield per tree by increasing the fruit size and number, the major yield
