The efficiency of water use (transpiration ratio) was investigated in various cultivars of grapevine by gravimetric and gasometric methods. Results of gravimetric measurements showed positive correlation between water use efficiency and vigor. Regression lines of the transpiration ratio on the final dry weight differed significantly in their curves and their distance from the coordinate axes. Statistical analysis showed that the quantitative effect of vigor on the water use efficiency was smaller in the cultivar Muscat Hamburg than in Sultanina and Queen of the Vineyards. Covariance analysis showed that Sultanina was a less efficient water user than Queen of the Vineyards for plants with the same vigor. Gasometric methods did not reveal any significant differences between the cultivars, probably due to the elimination of interference and boundary layer resistance effect.
In the fulltext the year is 1972.
