Effects of pruning levels of grapevine on canopy microclimate and plant water relation



Effects of pruning levels of grapevine on canopy microclimate and plant water relation



Acta Horticulturae Sinica 17(1): 13-20



The effects of pruning levels of grapevine on canopy microclimate and plant water relation in the temperate zone have rarely been reported. This experiment, established with four very different levels of pruning and carried out under the ecological conditions of the Bordeaux area (France, showed that, in comparison with the vines normally pruned, the level of radiation microclimate of the vines lightly pruned (bearing heavily) was not reduced in relation to the whole canopy. This was because of an efficient "autoregulation of growth"; but the shading of the fruits might be one of the important factors causing poor grape and wine qualities. Vines lightly pruned showed a more intensive transpiration of the whole canopy during the morning; but this brings about a more important "depression at midday" and a lower transpiration level during all the afternon, which was accompanied by a lower level of the stomate conductance of canopy and of the foliar water potential. This indicates severe foliar water deficits or a lower foliar activity. The mechanism of the effects of light pruning on radiation microclimate and plant water relation as well as on grape quality was discussed.
