Effect of peduncle xylem destruction, cluster detachment, and phloem girdling at the onset of ripening on growth and solute accumulation of Cabernet Sauvignon berries over 20 d

	Final berry weight (g)	Final solute concentration (°Brix)	Berry growth rate (mg d−1)	Solute accumulation rate (mg d−1)
Intact control	0.73±0.016 a	18.4±0.56 a	6.5±0.81 a	2.51±0.153 a
No xylem	0.69±0.050 a	18.5±0.24 a	6.5±1.33 a	2.60±0.325 a
Detached	0.47±0.022 b	18.1±0.25 a	-6.8±0.41 b	–0.01±0.002 b
Girdled	0.59±0.032	12.1±1.13	-3.9±0.79	–0.10±0.199

Data are means ±SE (n=6 clusters). Means followed by the same letter do not differ significantly at P <0.05 (note: girdling was tested in a separate experiment and is included here for comparison only).
