Floral Nectaries

The nectaries anatomical features of nine species of <em>Pomoideae</em> subfamily <em>Aronia melanocarpa</em> Ell., <em>Cotoneaster horizontalis</em> Decne, <em>C. praecox</em> Vilm.-Andr., <em>C. lucida</em> Schlecht., <em>Crataegus monogyna</em> Jacq., <em>C. coccinea</em> L., <em>C. crus-galli</em> L., <em>Sorbus aucuparia</em> L., <em>Sorbus intermedia</em> Pers. were compared. The flower longitudinal sections by means of vibratome and semithin slides by use of ultramicrotome were made. The thickness of nectary epidermis, glandular layer and the structure of subglandular layer as well as the n,n of vascular bundles were studied. It was stated that the height of epidermis cells and the thickness of their wall were approximate in the most investigated taxons. Stomata occurred in the nectaries of all species. They were located on a level with the epidermis cells in <em>Aronia</em> and <em>Sorbus</em> genera, in small hollows in Cotoneaster and considerably below the level of epidermis cells in <em>Crataegus</em>. The thickness of glandular layer was approximate for each genera. Sorbus intermedia and the species of <em>Crataegus</em> genus wer distinguishable by the thickest nectaries. The concentration of brachysclereids occurred in subglandular tissue of <em>Crataegus crus-galli</em> and of <em>Sorbus</em> both species. Vascular bundles, stocking the nectary, mostly consisted of phloem and xylem, but in <em>Aronia, Cotoneaster praecox</em> and <em>C. lucida</em> only phloem was noticed. The dependence between thickness of glandular layer, studied anatomical features and the volume of secreted nectar is discussed.

The Impact

ABSTRACT The present study determined the impact of Acrobasis advenella caterpillars feeding on the content of total proteins, specific proteins and soluble proteins in the inflorescences of three host plant species: Aronia melanocarpa, Sorbus aucuparia and Crataegus monogyna. The study demonstrated that the feeding of A. advenella caterpillars increases the total, specific and soluble protein contents in the inflorescences of these three plants. Significant increases in the content of these compounds were observed in the infested inflorescences of black chokeberry.

Abstract: The Sapotaceae family is recognized for its economic importance, presenting food, medicinal and timber potential. Pouteria andarahiensis T.D.Penn., popularly known as "massaranduba", is endemic to Chapada Diamantina, Bahia, Brazil, and is currently classified on the IUCN red list as "endangered". Pouteria andarahiensis is little studied, highlighting this work as the first anatomical study for the species. Light microscopy and scanning electron microscopy techniques were used to perform anatomical studies. The species showed characters shared with the family (laticifers and malpiguiaceous trichomes), as well as diagnostic characters and associated with xeromorphy. The data obtained from the leaf architecture can assist in the identification of the species in a vegetative state, while the leaf surface provided unpublished data to the species, indicating the presence of a cuticle with complex ornamentation. Stand out as xeromorphic anatomical features, high stomatal density, high number of trichomes per area, sclerenchymatic columns in the mesophyll and a subepidermal sclerenchyma layer connecting the vascular bundles in the mesophyll.

Introduction: Paliurus spina-christi Mill is a species with two varieties namely Paliurus spina-christi L. var. spina-christi and Paliurus spina-christivar. macrocarpa Beck native to mountains of Kurdistan, rarely growing in the upper plains of northern Iraq. Materials and Methods: A total of 15 plants from different parts of Kurdistan region were sampled. 30measurements for each characters of Leaf, Inflorescence, Flowers, Fruit, seeds, and leaf anatomical characters were measured for comparison between the two varieties. Results and Discussion: Fruit diameter of var. macrocarpa is significantly larger than fruit diameter of var. spina-christi. Most mean flower parts especially the ovary, in addition to seed size is larger in var. macrocarpa. Upper epidermal layer is always thicker than the lower epidermal layer for the same blade. The isobilateral mesophyll includes 2 layers of long palisade cells adaxially and 2-3 layers of short cells abaxially. Many vascular bundles are seen equally spaced in the mesophyll tissue.With the exception of the presence of simple hairs on the petiole adaxial side of the var. spina-cristi and the absence of these hairs from the same site of var. macrocarpa, all other anatomical features are considered to be of no taxonomic application. Stomatal density of the adaxial leaf side is up to 19 stomata per mm² in var. spina-christi while it is up to 38 stomata per mm² in var. macrocarpa. Conclusions: Both fruit diameter and the stomatal density of the adaxial leaf side constitute diagnostic characters for separating between the two varieties of Paliurus spina-christi Mill

Plumbago is a traditional medicinal plant in Ayurveda. The paper presents anatomical study of leaf, petiole, stem and root of two species of Plumbago namely P. zeylanica, P. auriculata and, its relevance in discrimination of these two species. Anatomical features of leaf which are of diagnostic value in delimitation of both taxa are outline of T. S.,shape and size of epidermal cells, presence of sclerenchyma surrounding the vascular bundles, number of tannins cells. Characters of taxonomic significance in petiole anatomy are outline of T. S, presence of trichomes, shape and size of epidermal cells, abundance of collenchyma, arrangement and number of vascular bundles, presence of sclerenchyma surrounding vascular bundles, number of tannin cells. The diagnostically useful anatomical features of stem to discriminate both taxa of Plumbago are degree of elevation of stem ridges, occurrence of double layered epidermis, size of epidermal cells, distinctness of endodermis, abundance and distribution of pericyclicsclerenchyama, number of vascular bundles. Anatomical features of taxonomic significance in root are width of cortex and abundance of starch grains in cortex cells, abundance and distribution of pericyclics clerenchyama, amount of vascularization, distribution, diameter and density of vessels, width of medullary ray.

A comparative study of the some leaf anatomical features of four species of Annona occurring in Nigerian was undertaken with the aid of light microscope. The four foliar structures (epidermis, petiole, midrib and lamina architecture) studied revealed useful characters which support recognition of the species. A combination of these features has been used to prepare an artificial indented dichotomous key for identifying the  species. The generic constant features encountered included hypostomata, paracytic stomatal type, linear nerves endings, uneven midrib outline, and centrally located vascular bundles in the petiole and midrib. However, the most reliable distinguishing characters found across the species included presence of brachyparacytic stomata in A. reticulata, presence of trichomes on the midrib in A. senegalensis, absence of druses on the abaxial surface in A. muricata and A. squamosa, a thick pitted anticlinal walls on the surfaces of A. muricata and consistent polygonal areola shape in A. squamosa. The overlapping characters which also justify the closeness of the species and their grouping in a genus were recorded in both the qualitative and quantitative features. Prominent among them are the mean stomatal width which is about 1.0 μm in all species, nerve endings within the areole which varies between 1-2, U- or V-shaped midrib on the adaxial surface and straight to curved anticlinal wall pattern. The significance of these observations is discussed in updating the existing data in the genus. Keywords: Epidermis, Microscopy, Midrib, Petiole,   Systematic

Fruit Stage

Developmental anatomy of eucalypt flower buds from flower to mature fruits was investigated using light microscopy. Several important features contribute to the maturity of flower and fruit. The epidermis of the flower in many species is replaced by periderm in the fruit. Brachysclereid idioblasts develop in the parenchymatous zone beneath the epidermis; fibres develop from cambium-like activity in the vascular bundles located in the mid-region of the ovary wall; and cells adjacent to the locule lining mature as transversely oriented filiform sclereids. The initiation of these features in relation to anthesis varies among taxa, and this influences flower and fruit anatomy and morphology. In taxa where sclereids and fibres are initiated following anthesis, there is substantial post-anthesis growth and fruits are larger than flowers. When these features are developed before anthesis, the flowers are essentially pre-fruits that exhibit little or no further growth in the fruit stage apart from additional cell-wall lignification. Several other anatomical features, such as oil ducts and the distribution of oil glands and crystal layers, are not developmentally variable, but are phylogenetically informative within the eucalypt group.
