STUDIES ON WATER RELATIONS OF GRAPEVINE (VITIS VINIFERA). EFFECTS OF SINKS ON LEAF WATER POTENTIAL AND TRANSPIRATION IN NON LIMITING WATER CONDITIONS |
| Authors: | C. Giulivo, G. Ponchia, F. Osele, A. Pitacco |
| Abstract:
The presence of sinks, both vegetative and reproductive, modifies the water relations of grapevines. The sinks enhance dehydration, induce a stable water potential at midday, and a slower rehydration. Transpiration rate is very little affected, but because of different leaf area water loss by transpiration is strongly dependent on the type and activity of sinks. | |
