“…Data concerning the size, shape and structure of seeds not only have been used as an important tool for solving various taxonomic problems within the genus Impatiens but also provide results useful for determining the impact of various environmental factors on the phenotypic variability of these species (Bell, Lechowicz & Schoen, 1991;Argyres & Schmitt, 1991;Schmitt, 1993;Chmura, Csontos & Sendek, 2013;Maciejewska-Rutkowska & Janczak, 2016).…”

“…Seed morphological features of Impatiens have not only been used for solving various taxonomic problems within the genus but also prove to be useful for determining the impact of various environmental factors on the phenotypic variability of balsam species (Argyres & Schmitt, 1991;Schmitt, 1993;Maciejewska-Rutkowska & Janczak, 2016). The understanding of environmentally induced variation in an individual plant phenotype is crucial for predicting population responses to environmental changes.…”

“…In fact, a detailed understanding of the seed morphology of the entire genus Impatiens is missing, despite major studies using novel imaging methods (e.g., Yuan et al, 2004;Ruchisansakun et al, 2015;Rahelivololona et al, 2018). As yet, only about 170 species have been investigated, which is about one fifth of all known balsams (Maciejewska-Rutkowska & Janczak, 2016).…”

Impatiens capensis is an annual plant native to eastern North America that is currently spreading across Europe. In Poland, due to this plant’s rapid spread in the secondary range and high competitiveness in relation to native species, it is considered a locally invasive species. The microstructure of seeds is an important tool for solving various taxonomic problems and also provides data useful for determining the impact of various environmental factors on the phenotypic variability of species. This issue is particularly important in regard to invasive species which occupy a wide range of habitats in the invaded range. There are few reports on seed size and thus far no descriptions of the seed ultrastructure of I. capensis in the analyzed literature. We present new data on the seed morphology of I. capensis growing in different habitats and conditions in the secondary range of the species. The studied populations differed significantly in each of the investigated traits (seed length, width, circumference, area, roundness, and mass). Our findings showed that anthropogenic disturbances in habitats and some soil parameters (presence of carbonates, potassium, loose sand, and moisture) were statistically significant with various seed sizes and morphology in the studied populations of I. capensis. Moreover, our studies showed maximum seed length (5.74 mm) and width (3.21 mm) exceeding those values given in the available literature. For the first time, we also provide a detailed SEM study of the ultrastructure of the seed coat of I. capensis. There are two types of epidermal cells on the seeds: (a) between the ribs (elongated with straight anticlinal walls, slightly concave outer periclinal walls, and micropapillate secondary sculpture on the edges with anticyclic walls), and (b) on the ribs (isodiametric cells with straight anticlinal walls and concave outer periclinal walls). Unlike the variability of size and weight of seeds, the coat ornamentation has turned out to be a steady feature within the studied secondary range of I. capensis.

“…Chen, Liu, et al, 2007;Utami & Shimizu, 2005;Zhang et al, 2016). However, seed coat micromorphology using the SEM technique has been studied in fewer than one fifth of the Impatiens species (Maciejewska-Rutkowska & Janczak, 2016). Of about 150 balsams known from NE India, seeds of almost 20 were investigated this way, for which, however, material was collected from other distribution sites, and only in one case (I. nagorum; Moaakum et al, 2017) seeds came from NE India.…”

“…Such studies are often incomplete and crucial information is missing, e.g., either measurements or only SEM images are published; these are rarely published together (Abid et al, 2011). To date, fewer than 200 species (<20%) have at least one study on seed ultrastructure published (Maciejewska-Rutkowska & Janczak, 2016), and only approximately 20 species (ca. 2%; our unpublished review) of balsams have more than one study available.…”

New Data on Seed Coat Micromorphology of Several Impatiens spp. from Northeast India

et al. 2020

This study aimed to analyze the seed coat structure of nine species from the genus Impatiens from Northeast India. A review of the available literature showed a scarcity of data on seed sizes and shapes, as well as a complete lack of information on the ultrastructure of seeds from five taxa of Impatiens determined with a scanning electron microscope (SEM). Photographs of the surface structure of seeds from the analyzed species were taken using an SEM and, from these, we measured the length and width of the seeds. The results showed differences in the seed ultrastructure and metric traits within the studied taxa. Based on the ornamentation of the epidermal cells, we distinguished three morphological types: protrusive, granulate, and reticulate. The seeds of the investigated species had ellipsoid, subellipsoid, or subspheroid shapes. Their lengths and widths ranged from 1.2 to 3.6 mm and 0.7 to 2.1 mm, respectively. The results of the study showed that the ultrastructures of Impatiens seeds are different among taxa and for some species can be used as a diagnostic character for their identification.
