However, it has hardly been tested whether there is a pronounced genetic impact resulting from different propagule types used for restoration. To address this knowledge gap, we carried out a pilot study based on a 20-years practical experiment, in which new populations of the rare and endangered herb <em>Armeria maritima</em> ssp. <em>elongata</em> were founded using seeds and/or young plants. The experiment took place in a nature reserve protecting a declining nutrient-poor sand-dune habitat. To evaluate if there was an effect of propagule type on genetic variation of restored populations, we compared populations of <em>A. maritima</em> ssp. <em>elongata</em> started by direct seeding, planting of seedlings and both seeding &amp; planting<em>.</em> Using molecular markers (AFLPs), we observed slightly higher levels of genetic diversity within restored compared to the source population. Genetic diversity was comparable in populations restored by different propagules, and genetic differentiation between the source and restored populations was absent. Our study provides a first piece of evidence that both seeds and young plants can be applied successfully in population restoration projects. We suggest to further test the impact of the reintroduction methods on restoration outcomes under different experimental settings, e.g. using species with different life history traits.</p></div>","PeriodicalId":55156,"journal":{"name":"Flora","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141779471","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}

Thus, <em>Pachycereus pringlei</em> – endemic to Mexican Sonoran Desert – plays a crucial role in the arid areas of Baja California Sur, Mexico acting as a refuge and food source for wildlife. The present study evaluates <em>P. pringlei</em> emergence, survival, and seedling growth under different solar exposure (open and shaded areas) levels, both in greenhouse and natural conditions. The results indicated that natural conditions and moisture significantly influenced seedling emergence and survival. Lack of soil moisture led to compaction, which may have reduced porous spaces and restricted air and water circulation, thereby affecting root growth during the establishment phase. Conversely, the emerged seedling proportion under greenhouse shade was higher than in natural conditions. Additionally, these seedlings exhibited superior stem development, while those exposed to sunlight notably developed root systems. Low water potential was recorded, reaching down to -5.1 MPa for seedlings exposed to higher light levels. However, relative water content (RWC) values in tissues exceeded 70 %. No significant relationship was found between photosynthetic pigment concentration and different light conditions. Despite adapting cacti to xeric environments, the results suggest they may not be fully prepared to withstand prolonged drought episodes during the seedling stage. Nevertheless, some morphological traits, such as stem length, spines, and root area showed significant variations under different light conditions, facilitating photosynthesis light capture.</p></div>","PeriodicalId":55156,"journal":{"name":"Flora","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141699777","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 one-way variance analysis (ANOVA) and principal component analysis (PCA) indicated that <em>C. asiatica</em> plants enhance different traits depending on the environment. Plants in shady microenvironments have greater petiole length, leaf area, fresh mass and leaf dryness compared to those occurring in sunny microenvironments. <em>C. asiatica</em> leaves are amphistomatic and in sunny microenvironments the chlorenchyma is more developed and has greater stomatal density on the abaxial surface. In urbanized areas, plants showed increased leaf area and fresh mass, and petiole thickening, and decreased leaf blade thickening. These traits may be related to the clay soil, which has greater water retention, and also to the shaded environment. Such adaptations allow the <em>C. asiatica</em> plants to maximize energy gain under different environmental conditions. Secretory canals were identified in all analyzed organs, which secreted acidic and neutral polysaccharides.

Here, we address the responses of leafless <em>Vanilla</em> spp. to open habitats, drought, and scarcity of large trees as phorophytes, with a focus on the root system. First, we compared the abundance of vanilla plants and root morphology in conserved and degraded forests. Next, we analysed the variations in root anatomical traits along a rainfall gradient. Our results showed contrasting responses depending on the ecoregion. In the northern humid forest, both the density of phorophytes and the number of vanillas per phorophyte were higher in the degraded forest than in the conserved forest. No such effects were observed in the southern dry forest. Furthermore, vanilla vines in the degraded humid forest developed more filiform roots for anchorage to smaller supports. <em>Vanilla</em> species occurring in semiarid climates, such as <em>V. bosseri</em> and <em>V. decaryana</em>, have larger underground roots with a thicker cortex to compensate for water rarity, as well as more vascular bundles to promote hydraulic conductivity, and more aerenchyma to decrease radial transport. Xylem vessel diameter is a plastic trait that increases with drought severity, as observed in one <em>V. madagascariensis</em> ecotype. These findings underline the high plasticity of the root system in leafless <em>Vanilla</em> spp. when facing habitat degradation and drought, and provide insights into their possible use in conservation and crop breeding.</p></div>","PeriodicalId":55156,"journal":{"name":"Flora","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0367253024001154/pdfft?md5=f6d65db4577eaf8c1556e93b3a49a053&pid=1-s2.0-S0367253024001154-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141630309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
