Abstract

In this research, the effects of foliar fertilizer Megegreen on stomata parameters of maize leaf (ZP 677) were studied. The experiment was performed on the experimental fields of the Institute of Agriculture, in Skopje, R. of Macedonia, during the 2008 and 2009. The foliar fertilizer was applied four times during the growing period in different concentrations of 0.3, 0.6 and 0.9% solution. Stomata density and size were measured on the adaxial and abaxial leaf surface from randomly selected plants from each replication in stage of silking. Stomata counts were made on the impressions from microscopic fields using the colodium method. Analyses of variance indicated that the application of foliar fertilizer has significant influence on stomata features on corn leaves. Results from research, show higher stomata density on adaxial (176,19-182,32 stomata/mm2) and abaxial surface (289,12-293,12 stomata/mm2) at variants 3 and 4. Variant 3 has the highest stomata length on adaxial surface (59,75 μm), without significant difference and the highest average length on the abaxial surface (63,00 μm), which is significantly different from the control variant. With the highest average width on adaxial leaf surface was variant 4 with 11,56 μm and on the abaxial surface was variant 2, with 13,49 μm. A positive significant correlation was observed between stomata number on the adaxial and abaxial surface of leaf (R2= 0,856**).
