MORPHOLOGICAL AND ANATOMICAL STRUCTURE OF GALLS IN GENISTA FLORIDA L. SUBSP. POLYGALIPHYLLA (BROT.) COUTHINO (LEGUMINOSAE)
This paper describes the morphology and anatomy of a structure which appears in the floral racemes of Genista florida L. subsp. polygaliphylla (Brot.) Couthino. In this subspecies the floral racemes have a small number of flowers. This structure develops quite frequently in this taxon, which is found in the northwest of the Iberian Peninsula, but never in Genista florida subsp. florida. Its morphology is simple: bottle-shaped, wide at the base and elongated to a narrow peak at the upper extreme. Anatomical examination shows that these structures have a close similarity to flowers. Since they develop by the oviposition of one insect of the Cecidomyiidae family in the floral buds, they can be…
Leaf domatia in the section Alaternus (Miller) DC. of the genus Rhamnus (Rhamnaceae)
Anatomical and morphological study of leaves from three species of Rhamnus (R. alaternus, R. myrtifolius and R. ludovici-salvatoris) which comprise the section Alaternus (Miller) DC. from the Iberian Peninsula and Balearic Islands, have revealed the presence of domatia, which are macroscopic infundibuliform structures. Although not all the leaves of one single plant showed domatia, all the individuals of each species examined presented these structures.
Effects of environmental factors on seed germination ofAnthyllis barba-jovisL
Abstract The influence of the main environmental factors on seed germination of Anthyllis barba-jovis L. were analysed. This work is part of a broader investigation aimed at the reintroduction of this species on Mount Conero, Ancona (central Italy), where it is at present extinct. The seeds were collected from the Gargano headland (southern Adriatic coast). Experimental analyses were carried out to determine: (i) dormancy levels of seeds collected in successive years, and also collected from the soil seed bank; (ii) effects of usual pre-treatments for overriding the physical dormancy of the seeds; (iii) optimal temperature range for maximum germination; (iv) effects of fire on seed germinat…
Medicinal Plants for Insomnia Related to Anxiety: An Updated Review.
AbstractSleep disorders are common among the general population and can generate health problems such as insomnia and anxiety. In addition to standard drugs and psychological interventions, there are different complementary plant-based therapies used to treat insomnia and anxiety. This review aimed to find and examine the most recent research on the use of herbal medicines for treating anxiety and insomnia as compiled from clinical trials, as well as to assess the safety and efficacy of these medicines and to elucidate their possible mechanisms of action. The process entailed a search of PubMed, Scopus, and the Cochrane Library databases from 2010 to 2020. The search terms included “sleep d…
Neuroprotective potential of Ginkgo biloba in retinal diseases
AbstractLike other tissues of the central nervous system, the retina is susceptible to damage by oxidative processes that result in several neurodegenerative disease such as age-related macular degeneration, diabetic retinopathy, glaucoma, ischaemic retinal disease, retinal disease produced by light oxidation, and detached retina, among other diseases. The use of antioxidant substances is a solution to some health problems caused by oxidative stress, because they regulate redox homeostasis and reduce oxidative stress. This is important for neurodegeneration linked to oxidation processes. In line with this, Ginkgo biloba is a medicinal plant with excellent antioxidant properties whose effect…
