Palynological studies were conducted to investigate the interspecific relationships among 43 Korean Viola taxa. Pollen of the genus Viola in Korea was monad in terms of the cell unit, and small or medium in size. The shape of the polar view was angular or circular, and the equatorial view was divided into prolate, subprolate, and prolate-spheroidal categories. The pollen polarity was isopolar, and the aperture type was 3–5 colporate. The surface sculptures of the equatorial view were found to be punctate-scabrate, punctate-rugulate, and punctate-rugulate-fossulate-scabrate. Consequently, as the pollen of most Viola taxa have similar morphological characters, it was difficult to construct a palynological description of each species. However, the seven taxa of V. arvensis, V. tricolor, V. diamantiaca, V. patrinii, V. mirabilis, V. grypoceras var. pubescens, and V. raddeana were clearly distinguished with morphologically similar species according to the aperture number, surface patterns and pollen sizes, all of which can be used as useful pollen characters.

“…There are also palynological studies of local and foreign authors for the representatives of this family [12,13,14,15,16]. Mehrvarz et al, [17] have studied the morphopalynological aspect of about 17 species of the genus Viola in Iran.…”

In this study there are demonstrated for the first time in albanian literature the palynomorphologic characteristics of two types of plants (Centaurea epirota and Viola epirota), collected in Zagoria valley, Gjirokastra region, in Albania. To carry out the study, light microscopy was used and it was concluded that the pollen grains of Centaurea epirota were 3 colporate, isopolar, with radial symmetry. In the polar view, the pollen grains have a circular triangular shape while in the equatorial view they have a compressed oval shape. Exine appeared scabrate. Viola epirota consisted of 3-4 colporate, sometimes even 5 colporate pollen grains. In the polar view, the pollen grains had a circular shape of 3 or 4 angles, sometimes even 5 angles while in the equatorial view they had an elliptical shape. Exine appeared granulate. To see the impact of ecological factor and the method of laboratory processing of pollen grains, the size of the new species studied was compared with the size of the pollen grains of Centaurea cyanus and Viola alba, Viola odorata and Viola arvensis, taken from the native literature.

Comprehensive characteristics and genetic diversity of the endemic Australian Viola banksii (section Erpetion, Violaceae)

et al. 2019

View full text Add to dashboard Cite

Viola banksii, the type species of section Erpetion, is endemic in eastern mainland Australia. In this paper we characterise morphological and anatomical features and assess genome size and genetic diversity in combination with the breeding system. V. banksii develops exclusively chasmogamous flowers. Ovules are anatropous, crassinucellate and bitegmic, the female gametophyte is of the Polygonum type, and the embryo is of Asterad type surrounded by nuclear endosperm. Pollen is non-heteromorphic, 3-aperturate, and highly viable. V. banksii grows in shade on moist, well drained, often sandy soils, and this is reflected in the anatomy of its organs, which includes a lack of subepidermal collenchyma in aerial parts, large leaf epidermal cells with thin cell walls, a narrow cuticle layer, and vascular bundles with xylem that are not rich in vessels. V. banksii is tolerant to zinc and lead based on phytotoxicity test. The high chromosome number (2n = 10x = 50) does not correspond to a small genome size (2C DNA = 1.27 pg). Low mean intra-populational gene diversity (HS = 0.077) detected by ISSR markers confirms the strong influence of selfing and clonal propagation by pseudostolons. Unique morphological traits of V. banksii include nyctinastic petal movement, the lack of a floral spur, the presence of gland-like protuberances on two stamens, and the presence of pseudostolons, which could be a synapomorphy for the whole section.
