treatment, compared with the other two treatments. The variation of dry weight reflects on assimilate allocation via sink-source relationships in a plant ( Dingkuhn et al., 2007 ; Patrick and Colyvas, 2014 ; Paul and Foyer, 2001 ). The assimilate

bud burst and fruit quality the next season was assessed. The practices chosen (pruning and cropload) had the potential to alter source:sink relationships and are readily applicable in commercial orchards. Summer pruning is a commonly used practice to

the developmental stage and source-sink relationships ( Privé et al., 1994 ). Late-season production based on summer pruning of primocane-fruiting cultivars is a low input system that can give high yields with good fruit quality. Pruning date and

, especially during summer, is still a big challenge because the yield is determined by several factors such as sink/source ratio, pollen activity, and fruit set. Studies have been done regarding the effects of high temperature on fruit growth, fruit load

; Gadagi et al., 2004 ). Finally, the source–sink relationships as modified by crop management and environmental factors, including abiotic and biotic stresses, may alter biomass and N partitioning and hence the N a UE when calculated on a part of the whole

compensated for by decreases in fruit size and yield ( Balibrea et al., 1999 ; Ehret and Ho, 1986 ). The sugar content of the fruit is determined by the complex interaction between source and sink metabolism. Modifications of fruit sink metabolism have been

result from genotypic differences in source or sink strength. Materials and Methods Experimental setup. Seeds from six pepper cultivars ( Capsicum annuum L.) differing in fruit size (20 to 205 g fresh weight; Table 1 ) were obtained from

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

from 15 to 25 μmol·m −2 ·s −1 ( Hancock et al., 1989b ; Schaffer et al., 1986 ); light saturation for strawberry cultivars is between 800 and 1000 μmol·m −2 ·s −1 ( Cameron and Hartley, 1990 ; Ferree and Stang, 1988 ). Source-sink ratio can cause
