Competitiveness Of Generalist Plant Populations At A Mine Site, Justin S.H. Wan, Fati̇h Fazlioğlu, Stephen P. Bonser
Competitiveness Of Generalist Plant Populations At A Mine Site, Justin S.H. Wan, Fati̇h Fazlioğlu, Stephen P. Bonser
Turkish Journal of Botany
Plants inhabiting extremely stressful mine site environments tend to be specialized and localized, where they express lower performance than nonmine site plants from adjacent areas. However, such a cost may be concealed. In a previous study at a mine site, we found mine and adjacent nonmine plants of multiple species expressed similar performances in the absence of competition. However, a lower competitive ability may be a concealed driver. We aim to test whether costs under competition could explain specialization. In a glasshouse experiment, we measured the performance (i.e. vegetative and reproductive growth) of mine and nonmine potted plants under competition. …

A Multiple Epidermis Or A Periderm In Parkinsonia Praecox (Fabaceae), Silvia Aguilar-Rodriguez, Teresa Terrazas, Xicotencatl Camacho-Coronel
Turkish Journal of Botany
A multiple epidermis in the green stems of Parkinsonia species has been described; however, there are disagreements among authors with regard to origin and tissues involved. The aims of this study were to identify the origin and development of the epidermis and cortex of P. praecox and relate these to possible adaptations to arid environments. Samples from new branches, to the stem, were removed and prepared using two embedding techniques. Our results show that the epidermis is simple, but periclinal divisions start far from the apical meristem. The inner derivatives maintained periclinal and anticlinal divisions, which are interpreted as meristematic, …
