Abstract
Measurements of weight losses of leaves cut off from plants of 44 potato cultivars were carried out in 1988–1995. Leaves were sampled at 7.00, 12,00 and 17.00 and weighted 3 times: just after cutting than 1 and 2 hours after cutting. Leaf weight losses 1 and 2 hours after cutting and index W being the proportion of these two values were assessed. Leaf weight losses and index W were the highest in the morning and decrease during the day. Significant influence of humidity and temperature of air was also observed. There were found a highly significant differences among cultivars for all parameters measured. The method seems to be quite good for stomatal efficiency assessment to compare genotypes for their defence ability against water losses from tissue.
