dc.description.abstract The aim of this study was to compare the ecophysiology character of Ecolly grape (Vitis vinifera L.) with the new technology-single crawled cordon training (SCCT) and traditional method-independent long-stem pruning (ILSP). The connections among net photosynthesis rate (Pn), transpiration rate (Tr), instantaneous water utilization efficiency (WUEi), stomatal conductance (Cs) and intercellular CO2 concentration (Ci) were always mutual and inextricable in the trial. The leaves in every stage had the highest Pn respectively when growing under the light irradiance of the different period. The ILSP showed a lower total photosynthetic capacity than the SCCT. There was the total semblable Tr for two pruning plants, but lower Tr in ILSP at the every position of the prior stage and riping stage (PS and RS) excluding the growing stage (GS). The WUEi declined because of the net CO2 assimilation saturated and the transpiration constantly fleetly increased before the photosynthetic active radiation (PAR) increased to 600 µmol·m-2·s-1. The increased WUEis from the first to the second stage deduced that stomatal closure at high irradiance reduced more Tr than Pn, while the values decreased again in the last stage indicated that stomatal opening at low irradiance added more Tr than Pn. These results suggested that it may be possible technology to change trellises in order to obtain better ecophysiology character in this study. The growth variability of vine may be affected by a particular training style. en_US
