). Transport of sugars and amino compounds in the phloem is accomplished by osmotically generated hydrostatic pressure differences between the source and sink ( Lalonde et al., 2003 ). Adequate K favors phloem loading by improving adenosine triphosphate

fruit enlargement is important to improve fruit quality and storage life. Sorbitol metabolism is influenced by environmental conditions. Under drought stress, both sorbitol synthesis in source leaves and its utilization in sink shoot tips are inhibited

). “Correlative control” is recognized as a significant developmentally regulated process in whole plant (monocarpic) senescence. In the correlative control process, a senescing vegetative source and a generative reproductive sink influence each other and thereby

cucumber do not consider daily temperature variations ( Augustin, 1984 ; Marcelis, 1994a ). One likely reason is that these models estimate fruit growth on the basis of daily sink/source relations. The source here is the assimilate pool recharged by
