Hylotelephium spectabile, a New Host for Carnation Tortrix Moth (Cacoecimorpha pronubana) and Molecular Characterization in Greece

2021

Simple Summary Hylotelephium spectabile (Saxifragales, Crassulaceae), a widespread ornamental plant was found infested by larvae of Cacoecimorpha pronubana (Lepidoptera, Tortricidae) a highly polyphagous pest of a wide range of crop, as well as ornamental plants. To the best of our knowledge, this finding suggests that H. spectabile should be considered a new host plant for C. pronubana. Moreover, molecular characterization of the Greek pest population place it along with European species clade. Abstract Cacoecimorpha pronubana (Hübner) (Lepidoptera, Tortricidae) is a highly polyphagous pest of a wide range of crop and ornamental plants. It is of Mediterranean origin and widespread in Europ…

Effects of plant density and cutting-type on rooting and growth of an extensive green roof of Sedum sediforme (Jacq.) Pau in a Mediterranean environm…

2020

Abstract Species of the Sedum genus are a popular choice for green roofs as they thrive in shallow growth layers and are resilient to extreme environmental conditions; they are also easy to propagate from seed, plantlings or plant parts. The use of rooted cuttings is most widespread due to good rates of establishment. In the interest of cost reduction, the direct spreading of Sedum cuttings over the roof area, especially over large areas, has attracted attention in recent years. Considering the interest on the above method and the seeming lack of experimental data available, this study aims to further knowledge in this area. Experimental tests on direct spreading of unrooted cuttings of Sed…

Vegetation growth parameters and leaf temperature: Experimental results from a six plots green roofs' system

2016

Abstract The paper provides a contribution for populating database of three physical parameters needed to model energy performance of buildings with green roofs: “coverage ratio” ( σ f ), leaf area index (LAI) and leaf temperature ( T f ). On purpose, six plant species were investigated experimentally: Phyla nordiflora, Aptenia lancifolia , Mesembryanthenum barbatus , Gazania nivea, Gazania uniflora , and Sedum . Proper ranges of the cited parameters have been found for each species. The here indicated ranges of σ f values refer to different growth levels of the species in the same lapse of time, that is four months. Single measured LAI values are also reported for the same plants. As for t…

Growth and development of succulent mixtures for extensive green roofs in a Mediterranean climate.

2022

Green roof systems, aimed at reducing anthropic impact on the environment, are considered environmental mitigation technologies and adopted by many countries across the world to strengthen urban ecosystem services. This study evaluates two mixtures of succulent: one of Crassulaceae and the other of Aizoaceae, used in the creation of a continuous and homogenous plant groundcover in Mediterranean environments. To assess the species mixtures, the parameters plant height, growth index, cover percentage and flowering were observed. Hydrological observations were also carried out to evaluate the rainfall retained by the test system in any given month. All data were subjected to analysis of varian…

Notulae to the Italian alien vascular flora: 2

2016

In this contribution, new data concerning the Italian distribution of alien vascular flora are presented. It includes new records, exclusions and confirmations for Italy or for Italian administrative regions for taxa in the genera Ageratum, Aster, Buddleja, Cedrus, Centranthus, Cephalotaxus, Clerodendrum, Cotoneaster, Cyperus, Honorius, Lantana, Ligustrum, Morus, Muscari, Oenothera, Opuntia, Platycladus, Plumbago, Pseudotsuga, Sedum, Sporobolus, Stachys, Ulmus and Yucca. A nomen novum, Stachys talbotii, is proposed as a replacement name for Sideritis purpurea.

Effect of CCC and pH on shoot elongation in Sedum rubrotinctum R.T. Clausen

2002

Sedum rubrotinctum plants grown during winter in a glasshouse had decreased leaf density and increased internode length as well as loss of red coloring, leading to diminished ornamental value. Treatment with growth retardant (2-chloroethyl)trimethyl ammonium chloride (CCC) reduced internode length as well as the number of internodes. Concomitant changes of ethylene production and peroxidase activity were found in CCC-treated plants. Substrate pH had a significant effect on the growth of S. rubrotinctum. This leads to the conclusion that increase of shoot growth during winter period could be reversed by means of growth retardant CCC and acidification of substrate.

Studies on sedum taxa found in Sicily (Italy) for mediterranean extensive green roofs

2018

One type of green roof whose function is ecological and environmental rather than aesthetic is the extensive green roof. Many studies have shown that Sedum performs very well compared to other hardy species in substrates of less than 10 cm. It seems that Sedum species are able to survive in very thin substrates; they tolerate extreme temperatures and sudden variations in temperatures, high levels of solar radiation, strong winds, poor substrate fertility and extreme drought. In particular, this paper looks at the potential of a number of species from the Sicilian taxa of the genus Sedum (Crassulaceae), which are considered to be those xerophytes most suited for use in extensive green roof s…

Provisional list of succulent species of the Mediterranean Region

1997

Succulent plants are relatively scarce in the Mediterranean Region, and dominant in a few areas. Most species belong to genera of Crassulaceae widespread in the boreal Regions. The main threat for succulents in the area is habitat modification and destruction. Industrial and touristic development, grazing, dams and mining activities are relevant factors of risk, as well as fires and invasive species.
