The effect of stomatal density on different stionic combinations of ber (Zizyphus mauritiana Lamk.) were studied. There were significant differences in stomatal density, internodal length and plant growth in all the stionic combinations. The minimum stomatal density, internodal length and plant height were recorded in Gola budded on Z nummularia and was found the most dwarfing combination. While, stionic combination of cultivar Ponda budded on rootstock Z mauritiana ecotype-Assam-Gauhati was found the most vigorous where the maximum stomatal density, internodal length and plant height were observed. The rootstock Z mauritiana ecotype-291 was found most compatible and moderate in plant growth, stomatal density and internodal length thereby giving moderate vigour to trees.
