Streszczenie:

The Geminivirus in chili plants is a significant problem in chili cultivation. Symptoms of Geminivirus infection are quite easy to find in chili plants because the symptoms are quite typical: mosaic, yellowing, small leaves, leaf lamina malformation, and stunting. The visual changes in leaf morphology are due to the leaf tissue structure, such as the upper and lower epidermis and the mesophyll tissue, including the palisade and sponge. There is little information about changes in the structure of chili plants infected with the Geminivirus. Therefore, this study aims to add information about ch

Typically reorganization of leaf tissue consisted in replacement of the spongy parenchyma by a palisade parenchyma. Palisade parenchyma tissues were compact in comparison to healthy. Abnormal cambial activity was observed in conducting tissue. Weaker selerenchyma rings were narrow and these were fewer narrow xylem

The effect of CO2 and NaCl on the second trifoliate leaf of Phaseolus vulgaris L. was studied. Salt reduced leaf area and volume. Volume density of the palisade mesophyll was increased and that of the intercellular spaces and abaxial epidermis was reduced. Salt increased the numbers of epidermal and palisade cells per unit area and the stomatal density of the abaxial epidermis but reduced the numbers of cells per leaf. Salt reduced stomatal indices of both epidermal surfaces, cell volumes, relative leaf expansion rate, leaf plastochron index, leaf fresh and dry weights, and specific leaf area.

The mature cyathial nectary of <i>Euphorbia heterophylla</i> L. consists of distint secretory and sub-secretory zones. The secretory zone consists of 1-3 layer of palisade-like epidermal cells, supplied by both phloem and xylem. Distinct 'secretory pits' surrounded by thin cuticle are present in the secretory tissue. Enzymes such as succinic dehydrogenase and acid phosphatase were localized. Probable functions of cyathial nectaries and animal visitors are discussed.

Streszczenie:

Specific leaf area (SLA) is an important leaf attribute representing a compromise between the capture of light and CO2 and the limitations imposed by leaf structure, herbivore resistance and the mitigation of water loss. We examined three Eucalyptus L'Her. species to determine whether variation in CO2 assimilation rate was related to SLA and leaf anatomy. Seedlings were grown in a naturally illuminated glasshouse with adequate water and nutrients. Light-saturated rates of photosynthesis were measured on the youngest fully expanded leaves. Mesophyll characteristics were measured from sections t

Squash silverleaf (SSL) is a physiological disorder of vegetables in the genus Cucurbita L. caused by feeding of nymphs of the silverleaf whitefly (SLW) (Bemisia argentifolii Bellows & Perring). SSL causes a silvering of the leaves and a blanching of fruit. Leaf silvering is caused by developmental separation of the upper epidermis and the palisade mesophyll layer resulting in additional air space and altered light reflection. The anatomical development of SSL was analyzed in young leaves of zucchini squash (Cucurbita pepo L.) using two susceptible genotypes (`Elite' and YSN347-PMR) and tw

Abstract A mosaic disease of wax myrtle (Myrica cerifera L.) occurring in Florida is described. Affected plants had small, distorted leaves that displayed a virus-like mosaic pattern characterized by pale green blistered areas interspersed with dark green, normal-colored tissues. Affected epidermal, palisade, and spongy mesophyll cells were disorganized, distorted, and frequently contained fewer definable chloroplasts than healthy leaves. Standard virus indexing techniques yielded no evidence of a viral etiology; however, a new species of eriophyid mite, Calepitrimerus ceriferaphagus Cromroy,
