The performed studies focused on the surface structure of floral nectaries of four species from the following genus: C. coccinea L , C. crus-galli L, C. curvisepala Lindm and C. prunifolia (Poiret) Pers. The observations of the epidermis area were made in a scanning electron microscope (SEM). A nectary appears to be shaped like a slightly curved disk situated between the pistil style and the basal...
The conducted study related to the structure of the floral nectaries of Rhododendron japonicum (A. Gray) J. V. Suringar ex E. H. Wilson. The structure of the secretory epidermis of the nectaries was analysed by using scanning electron microscopy (SEM). Rhododendron japonicum develops the superior pistil with a 5-loculed ovary equipped in five ribs. The nectary gland is located in the lower part of...
The structure of receptacular surfaces of floral nectaries at two flowering stages and the structure of the outer surface of the receptacle of Sorbus aucuparia were investigated using scanning electron microscopy. Changes in the development of the cuticular epithelium of the nectary epidermis and differences in the degree of aperture of stomata were observed. Increased undulation of the gland surface...
