Biologic research uses many ratio-based expressions to interpret experimental results. When we evaluated citations in physiology subsections (developmental, environmental stress, photosynthesis, source sink) of the Journal of the American Society

seeds. However, the role of source vs. sink relations could not be determined from this study, and the declines in seed carbohydrates could have been a consequence of declines in whole-tree health and not due to direct seed infestations per se. The seed

reproductive growth stage than the vegetative growth stage, a phenomenon associated with a sink-source relationship ( Ho, 1988 ). The reduction in sink activity caused an increase in sucrose in source leaves and led to a decrease in photosynthetic rate by

yield was found to be insignificant. These findings indicate that pollination may, in fact, not be a yield limiting factor for ‘Duke’ grown in western Washington. Other source-sink, climactic, and management factors may be responsible for the regional

Blake (1994) attribute the loss of total nonstructural carbohydrates to the loss of leaves, the source of carbon and growth hormones in the plants’ source–sink relationship. In a similar way, watermelon rootstock seedlings may be dependent on the
