Сравнительное Исследование Морфологии Спор Родов Подсемейства Cryptogrammoideae

Abstract

Using the method of scanning electronic microscopy (SEM), a comparative study of twelve representatives of subfamily Cryptogrammoideae S.Linds. family Pteridaceae E.D.M.Kirchn. was carried out. A comparative study of morphological characters of investigated spores has revealed characters that allow considering the relatedness of the studied species to one subfamilyCryptogrammoideae. These characters include: spore form is roundish-triangular, lociniate in proximal-polar and distal-polar positions; spore contour is low-crenate to smooth; distal side of the spore in an equatorial position is convex; rays of laesura are straight, raised over a sporoderm surface; exosporium is clearly defined from fine-granulate to verrucate.

Spore morphology of Haplopteris C. Presl species (Vittarioideae, Pteridaceae) from China

“…H. linearifolia (Fig. 2, A-D In contrast with most Pteridaceae species having tetrahedral trilete spores with very distinctive sculpture, that were described in multiple papers (Sladkov, 1961;Nayar, Devi, 1967;Tryon, Lugardon, B., 1991;Demske et al, 2013;Kuznetzov et al, 2014;Vaganov, 2016;Vaganov et al, 2017a, b, c, d), Haplopteris species has bilateral monolete spores. Spores of four examined species are very similar in shape to each other.…”

“…Our previous studies of spores of some Pteridaceae groups are shown that spore morphology studied using SEM-method and molecular-phylogenetic results are congruent for different genera such as Onichium (Vaganov et al, 2017a), Pityrogramma (Vaganov et al, 2017b), Vaginularia (Vaganov et al, 2017c). Morphology of spores is very important for systematics of subfamilies Pteridoideae (Kuznetsov, 2014), Cryptogrammoideae (Vaganov, 2016) and Ceratopteridoideae (Vaganov et al, 2017c).…”

The approach to the comparative morphological analysis of spores of the Pteridaceae E. D. M. Kirchn family representatives (Pteridophyta) based on phylogenetic relationship data

“…Sm.) R. M. Tryon семейства Pteridaceae E. D. M. Kirchn являются: споры тетраэдрической формы до трилетно-округлых, лучей лезуры три -прямые, экзоспорий четко выраженный без выростов (Ваганов и др., 2014;Vaganov, 2016;Vaganov et al, 2017).…”

“…Материалы и методы. Подробные описания морфологии спор, полученные в предыдущих работах по представителям семейства Pteridaceae методом СЭМ (Vaganov, 2016;Vaganov et al, 2017Vaganov et al, , 2018Vaganov et al, , 2020, позволили нам подготовить таблицу со стандартизованными признаками представителя трех подсемейств семейства Pteridaceae. В данном исследовании нами умышленно не используются мерные признаки спор (экваториальный диаметр, полярная ось, длина и ширина лезуры) ввиду фокуса исследования на качественных признаках представителей семейства.…”

Spore morphology of Vaginularia Fée species (Pteridaceae) from South-Eastern Asia A.

“…It was shoved on numerous example that spore morphology and molecular-phylogenetic results are congruent for different genera such as Gymnocarpium and Cystopteris (Gureyeva, Kuznetsov, 2015), Onichium (Vaganov et al, 2017 a, b, c), Pityrogramma (Vaganov et al, 2017b) therefore the morphology of spores has phylogenetic signification. Spore morphology is very important for systematics of Pteridaceae subfamilies: Cryptogrammoideae (Vaganov, 2016) and Ceratopteridoideae (Vaganov et al, 2017c).…”
