, despite overall low scaffold or whole-canopy crop loads (T.C. Einhorn, unpublished). These observations indicate that branches behave as semiautonomous units, and local source:sink imbalances cannot be corrected by high leaf area to fruit ratios of

. In spring, TB iris produces great amounts of shoot growth, which requires sufficient nutrient supply from both internal and external sources. Usually, fertilization in early spring and after spring flowering is recommended for growing TB iris

). Total carbohydrates in the rose ( Rosa hybrids L.) corolla decrease with time, but not as much as in the leaves; and the decrease in the corolla is more pronounced when leaves on cut flowers were removed, suggesting a source-sink relationship from
