Apoplastic peroxidase distribution in transmitting tissue of the stylar ‘neck’ was investigated using the DAB cytochemical reaction applied to electron microscopy in non-, self- and cross-pollinated pistils of Primula acaulis (‘pin’ morph) ex

SUMMARYPrimula acaulis is characterized by an heteromorphic incompatibility. Through electron microscopic techniques, based on the DAB cytochemical reaction, it has been possible to detect the presence of peroxidase in the intercellular spaces and in

SUMMARYThis study gives the results of investigations made on the ultrastructure of Chenopodium amaranticolor Coste & Reyn foliar trichomes. These hairs, when localized on subapical leaves, have a pigmentation which is due to the presence of betalain

Using light and electron microscopy, we have studied the microsporogenesis and tapetal development of the feathers in two different low producing clones of Picolit giallo (sp. Vitis vinifera). In these clones while the productivity of the main branch

SUMMARYThe pellicle of five species of Euglena, belonging to three different groups (Catilliferae, Radiatae and Serpentes), was studied by transmission electron microscopy, in order to see if pellicular morphology could be taken as a valuable charact

SUMMARYChenopodium amaranticolor leaves have been supplied with low and high molarity of NaCl. The ultrastructure of the foliar hair shows a cytoplasmic vesiculation when the leaves have been treated with high molarity of NaCl in the light. A similar

SUMMARYThe genus Exobasidium has been long questioned in relation to other Basidiomycetes. Reproductive aspects of Exobasidium rhododendri, in host tissues, have been here taken into consideration and the pore ultrastructure has been compared with ot

SUMMARYThe presence and distribution of peroxidase activity has been examined in non-, self- and cross-pollinated bud styles, in relation to the well-known bud pseudo-self-compatibility. No peroxidase activity is present in the apoplastic space of no
