Early sowing can boost grain production by reducing weed infestation in organic no‐till wheat

2022

Conservative tillage techniques have several agro-ecological benefits for organic farming. The application of these techniques, however, can create quite a few challenges due to the increased weed competition. Here, we report the results of an organic field experiment in which the responses of wheat and weeds to no tillage (NT) were evaluated compared with conventional tillage (CT). We also tested the hypothesis that, under NT, moving up the sowing date, compared with using the ordinary sowing date for the study area, can result in increased competitiveness of the crop against weeds. Two wheat genotypes, a modern variety and an ancient landrace, were tested.Substantial reductions in grain y…

Established cotton stainer gut bacterial mutualists evade regulation by host antimicrobial peptides

2019

Symbioses with microorganisms are ubiquitous in nature and confer important ecological traits to animal hosts but also require control mechanisms to ensure homeostasis of the symbiotic interactions. In addition to protecting hosts against pathogens, animal immune systems recognize, respond to, and regulate mutualists. The gut bacterial symbionts of the cotton stainer bug, Dysdercus fasciatus, elicit an immune response characterized by the upregulation of c-type lysozyme and the antimicrobial peptide pyrrhocoricin in bugs with their native gut microbiota compared to that in dysbiotic insects. In this study, we investigated the impact of the elicited antimicrobial immune response on the estab…

THE MEDITERRANEAN AS SOURCE OF ORNAMENTALS

2013

Cultivation of plants for ornamental purposes throughout the Mediterranean dates back to deep antiquity. In fact Egyptian, Greek, Roman and other previous myths are pervaded with correlations among humans, gods and plants either useful or ornamental – whose names such as hyacinth, narcissus, and many others that are still common. In that period almost all of the ornamental flora was native to the Mediterranean and next countries, having been the flow from other territories irrelevant up to the Renaissance. From XVI century on, the whole Mediterranean ornamental heritage was gradually spread throughout the new discovered territories, and from there a huge number of plants was introduced to M…

The chemical composition of the floral extract of Epipogium Aphyllum sw. (Orchidaceae): A cluefor thier pollination biology

2014

Epipogium aphyllum is a rare European obligate mycoheterotrophic orchid lacking chlorophyll. It has not been studied previously with respect to pollination biology. We studied the association between the composition of floral scent emission and its pollination systems. Field observation indicates that the main pollinators of Epipogium aphyllum are representatives of the genus Bombus (Hymenoptera), B. lucorum, B. hortorum, B. terrestris, B. pascuorum and B. proteus, and the genus Apis (Hymenoptera) namely A. mellifera. The main potential vector (observed to accidentally carry pollen), is most likely Episyrphus balteatus (Diptera, Syrphidae). The chemical composition of the floral extracts of…

A new subspecies of Epipactis microphylla (Orchidaceae; Epidendroideae) from Pantelleria Island (Sicily)

2021

A new subspecies of Epipactis microphylla, proposed as subsp. cossyrensis is described and illustrated from Pantelleria, a volcanic island near Sicily. It differs from subsp. microphylla mainly in the shape and size of leaves and bracts and several floral traits. This taxon, previously attributed to E. pollinensis, a species currently treated as a synonym of E. purpurata, grows in the undergrowth of thermophilous woodlands occurring on the top of the island, where it numbers a few tens of individuals. The conservation status, phenology and taxonomic remarks are provided. Keys for the species belonging to the Epipactis atrorubens group (= subsect. Atrorubensae), including E. microphylla, are…
