Position-dependent reproductive success of flowers in Dactylorhiza maculata (Orchidaceae)
2000
1. This study explores the importance of flower position for reproductive success of individual flowers of the deceptive terrestrial orchid, Dactylorhiza maculata (L.) Soo. 2. Upper flowers had smaller lips and produced lighter pollinia than those in other parts of the inflorescence, probably due to architectural effects. 3. Dry weight of seed capsules decreased from bottom to top in the inflorescence in both open-pollinated and hand-pollinated plants. However, removal of flowers from the middle and lowest parts of the inflorescence considerably increased seed production of the upper flowers. Decreased seed set was due to decreased resource availability because of the long maintenance time …
The recreational value of botanic garden events: A case study of the Zagara plant fair in Palermo, Italy
2022
Botanic gardens are defined by their mission to maintain living plant collections for scientific research, conservation, display and education. This mission represents the potential ecosystem services that botanic gardens aim to produce, with display and education specifically regarding recreational ecosystem services (RES). Visitors must directly experience botanic gardens to transform these potential RES into real benefits, yet the public may not be interested in studying plants during their leisure time. Thus, botanic gardens turn to events to attract visitors. The objective of this study is to estimate the RES benefits created by a botanic garden event and profile the visitors that it b…

Water retention characteristics of substrates containing biochar and compost as peat and perlite replacements for ornamental plant production
2021
In Italy peat and perlite are commonly used as growth substrates in ornamental plant nurseries. Requests for ecologically sustainable growth substrates have recently focused research on the study of new media. In this context, biochar and compost, by-products of other production chains, may play a relevant role. Four growth substrates were prepared by mixing (v/v) different porous matrices including a 2-mm sieved sandy loam soil namely: 50% peat and 50% perlite (PPr), 50% compost and 50% biochar (CB), 25% peat, 25% perlite, 25% compost and 25% biochar (PPrCB) and 25% peat, 25% compost and 50% mineral soil (PCM). Water retention curves of porous matrices and growth substrates were determined…
Draft Genome Sequences of Dickeya sp. Isolates B16 (NIB Z 2098) and S1 (NIB Z 2099) Causing Soft Rot of Phalaenopsis Orchids
2015
ABSTRACT The genus Dickeya contains bacteria causing soft rot of economically important crops and ornamental plants. Here, we report the draft genome sequences of two Dickeya sp. isolates from rotted leaves of Phalaenopsis orchids.
Ethnopharmacology, phytochemistry, chemical ecology and invasion biology of Acanthus mollis L.
2022
Abstract Ethnopharmacological relevance Acanthus mollis L. (Bear's Breeches) is a wide-spread medicinal and ornamental plant and is particularly suited to exemplarily illustrate the diverse aspects of invasion biology by neophytes. Since ancient times, it has been a popular Mediterranean ornamental plant in horticulture and served as model for the decoration of column capitals in architecture. Aim of the study In the present review, we aimed to give an overview about ethnopharmacology, phytochemistry, chemical ecology, and invasion biology of A. mollis. Thus, the importance of plantation cultivation in the presence of ecologically problematic species and environmental protection were emphas…
Molecular analysis ofPhytophthoradiversity in nursery-grown ornamental and fruit plants
2015
The genetic diversity of Phytophthora spp. was investigated in potted ornamental and fruit tree species. A metabarcoding approach was used, based on a semi-nested PCR with Phytophthora genus-specific primers targeting the ITS1 region of the rDNA. More than 50 ITS1 sequence types representing at least 15 distinct Phytophthora taxa were detected. Nine had ITS sequences that grouped them in defined taxonomic groups (P. nicotianae, P. citrophthora, P. meadii, P. taxon Pgchlamydo, P. cinnamomi, P. parvispora, P. cambivora, P. niederhauserii and P. lateralis) whereas three phylotypes were associated to two or more taxa (P. citricola taxon E or III; P. pseudosyringae, P. ilicis or P. nemorosa; and…
Lavandula spp. (Lavender): In Vitro Culture, Regeneration of Plants, and the Formation of Essential Oils and Pigments
1991
Lavandula species are of great interest due to their content of essential oils, which are important to the perfume, cosmetic, flavoring and pharmaceutical industries. They also have numerous other applications, including their uses as ornamental and melliferous plants.
Las áreas recreativas forestales como puntos para la naturalización de especies vegetales alóctonas: el ejemplo del género Acer L. (Aceraceae) en el …
2018
Se aporta información sobre un caso de naturalización de nuevas especies forestales para la Comunidad Valenciana (España) procedentes del uso de plantas no nativas en el acondicionamiento de áreas recreativas forestales y su entorno. Como ejemplo de ello, alrededor del área de pícnic forestal 'Fuente Umbría' (Umbría del Fresnal, Buñol, Valencia), dos especies alóctonas para esta zona de la Comunidad Valenciana, Acer pseudoplatanus L. y A. platanoides L., plantadas hace 40-50 años como árboles ornamentales, se han naturalizado y actúan como nuevas especies invasoras. Para ambas especies, se trata de la primera mención georreferenciada como plantas exóticas invasoras en la Comunidad Valencian…
Nuevas citas de plantas alóctonas suculentas asilvestradas en la Comunidad Valenciana
2014
Se aportan citas de diversas especies de suculentas naturalizadas de las familias Cactaceae, Crassulaceae y Euphorbiaceae para la flora alóctona valenciana, algunas nuevas como Aeonium decorum Webb. ex Bolle, Echinopsis oxygona (Link) Zucc. ex Pfeiff., Pachyphytum bracteosum Link, Klotzsch & Otto y Euphorbia abyssinica J. F. Gmel. -- Appointments for several species of succulent plants naturalized in the Valencian Community (Spain) are given for the families Cactaceae, Crassulaceae and Euphorbiaceae. Some of them are floristic novelties for the Valencian alien flora, such as Aeonium decorum Webb. ex Bolle, Echinopsis oxygona (Link) Zucc. ex Pfeiff., Pachyphytum bracteosum Link, Klotzsch & O…
