Effect of BA and GA3 on the Morphological Features of Stomata in the Leaf Epidermis of the <i>Zantedeschia albomaculata </i> cv. ‘Albomaculata’

The study focused on the effect of benzyladenine at concentrations of 100, 350 and 600 mg-dm-3 combined with gibberellic acid at the same concentrations on the morphological features (length and width) and number of stomata in the lower and upper leaf epidermis in <i>Zantedeschia albomaculata...

Description
Summary:The study focused on the effect of benzyladenine at concentrations of 100, 350 and 600 mg-dm-3 combined with gibberellic acid at the same concentrations on the morphological features (length and width) and number of stomata in the lower and upper leaf epidermis in <i>Zantedeschia albomaculata </i>cv. ‘Albomaculata’. To determine changes in the structure of stomata, rhizomes were soaked before planting in mixtures of the growth regulators at the above concentrations for 30 minutes. After the application of BA and GA3 at concentrations of 100+100 mg-dm-3and 350+350 mg-dm-3 the stomata in the upper leaf epidermis were larger than in the control treatment and fewer in number. In the lower epidermis a mixture of BA and GA3 at concentrations of 100+100, 350+350 and 600+600 mg-dm-3 caused the formation of bigger stomata, and their number declined when the concentration employed was 350+350 mg-dm-3.
