However, little is known about the effect of these characteristics on root anatomy and mechanical properties of the root tissues. Anatomical features of maize roots grown in media that varied in density and/or structure (soil, glass beads, vermiculite) were analyzed on cross-sections through the elongation and maturation zones of the roots of 14-day-old seedlings. The sections were stained for lignin and suberin to recognize the developmental stages of exodermis and endodermis. Cortex thickness, number of cortical cell layers, and diameter of the vascular cylinder (stele) were measured in both zones. The Young's modulus of the roots was determined using mechanical tensile tests. Assuming that the root can be considered a composite material, a model was used that allowed, for the first time, to estimate the mechanical properties of the stele and cortex. \u0000While the cell arrangement of roots grown in a medium with high density and fine movable particles (soil) was regular, roots grown in a medium with low density and light particles (vermiculite) and a medium with high density and large unmovable particles (glass beads) showed early damage of the rhizodermis and impaired cell arrangement in the cortex and vascular cylinder. In these roots, the exodermis and endodermis matured closer to the root tip than in roots from the soil. The vermiculite roots were the most outliers regarding morphometric parameters and mechanical properties. The Young's modulus of the stele was many times greater than the Young's modulus of the cortex in the roots of all variants. Of the media used in the experiment, the soil appears to be most favorable for the maize root growth and development.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141341048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to, re-analyze the status of this plant community with reference to species composition, functional structure, habitat conditions and syntaxonomic position 50 years afer its discovery, and first description. For this purpose, we used archival and contemporary data. The obtained results revealed close compositional similarity between the vegetation plots collected in 1968 and 2022. The abundance of relic species documented in phytosociological relevès has remained constant (Sesleria tatrae, Galium anisophyllon) or increased (Scabiosa lucida). Additionally, the first locality of Calamagrostis varia was found on the Pulinka – a species not yet recorded in the Sudetes. On the other hand, some regular fluctuations in the abundance of sporadic species were observed. However, these were not reflected in changes in community-weighted means for environmental variables (temperature, light, nutrients, soil reaction, and moisture) and functional traits (specific leaf area, seed mass, and leaf dry matter content). We also found no\u0000differences in the functional diversity index (FD Rao) between the first and last surveys. Therefore, the lack of temporal changes in the main ecological features may indicate a high stability of the studied grasslands despite the pressure of external factors (progressive climate warming and nitrogen deposition). The phytosociological analysis carried out suggests that the studied community belongs to the class Elyno-Seslerietea and the order Seslerietalia caeruleae. However, due to the unusually poor species composition of the studied rocky grasslands, we did not find it currently possible to classify them at the alliance and association level. This requires further studies and classification based on broader data, including Western Carpathian calcicolous swards.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140710851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Link is a native shrub, common both in Europe and Poland and in many other areas of the world, it is considered an invasive plant. e size of the organs of generative reproduction and the factors determining it are still poorly understood. The study of the size of broom flowers, fruits, seeds and leaves was carried out on 16 plots in western Poland. Habitats were described using Ellenberg’s index values, which allowed us to divide the study into two types: warm, rich in nitrogen, and moister with higher pH. It has been shown that a significant part of the variability in the size of flowers and their elements is conditioned by inter-individual differences. Some features (wings and keel area, number of seeds, or nitrogen content in stems) are also dependent on the type of habitat. Probably the key factor influencing the size of generative organs and the number of seeds is the availability of water in the environment. In more moist habitats and with a higher pH, the organs of generative reproduction are larger, and the nitrogen content is lower. The size of individual elements of the perianth is significantly correlated with each other, and the number of seeds depends on the size of the keel. Depending on environmental factors, the size of the generative organs may affect the efficiency of pollination, which in turn determines the size and number of seeds. The ability of C. scoparius to adapt to various edaphic conditions, the ability to establish symbiosis with atmospheric nitrogen-fixing bacteria, and the production of size-diverse flowers that can be pollinated by insects of various sizes determine its invasive success.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139244298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most probably, such a mating system leads to the emergence of separate lineages of apomictic plants with increased ploidy levels, each of which has a complete set of genomes of its putative (most probably triploid) apomictic parent. The correct identification of such lineages could facilitate taxonomic and phylogenetic research in Hieracium. In this paper, we analyzed the distribution of the 5S and 45S rDNA segments in the karyotypes of six selected Hieracium taxa, representing all ploidy levels reported in the genus: H. alpinum 2x, H. alpinum 3x, H. schustleri 4x, H. chrysostyloides 5x (H. sect. Alpina) and H. bifidum 3x, H. levicaule 3x (H. sect. Bifida). The analyzed rDNA markers suggest that two taxa of the higher ploidy level (4x and 5x) belonging to H. sect. Alpina inherited three genomes from the triploid H. alpinum, which has 2:1 genomic composition with two genomes from diploid H. alpinum and one genome with an untypical 5S rDNA-bearing chromosome of unknown origin. H. bifidum and H. levicaule differ from each other in the rDNA distribution pattern, which suggests that H. sect. Bifida may be a less homogenous group of species.","PeriodicalId":7157,"journal":{"name":"Acta Societatis Botanicorum Poloniae","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135618795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
