Abstract

A virus was isolated from Lavandula angustifolia Mill. plants exhibiting yellow mottling and distortion of leaves. After mechanical inoculation it induced in the major part of used test plants symptoms characteristic for Cucumber mosaic virus (CMV). Its standard properties regarding the stability in crude plant sap were as follows: longevity in vitro 1-2 days, thermal inactivation point 55-60°C, dilution end point log10minus 3 - 4. The virus reacted positive with diagnostic antiserum against CMV in DAS-ELISA test. RT-PCR reaction revealed similarity between the investigated isolate and the isolate of CMV from the Netherlands belonging to subgroup II. In the light of the foregoing facts the isolated pathogen can be identified as the Cucumber mosaic virus and Lavandula angustifolia may be regarded as its natural host.

Summary

Root-knot nematodes (RKN), Meloidogyne spp., have a wide host range and are common in the Mediterranean area. Cultivated lavender (Lavandula angustifolia) was found naturally infested by M. hapla in Kozani area, the first documented infestation of this crop by RKN in Greece. Oxalis pescaprae, a common winter weed in Crete, was found to be a host of M. javanica under artificial inoculation. This weed acts as a potential winter host of the nematode in fields cultivated with vegetable crops. Two populations of M. ethiopica were found in kiwi and maize in Greece in the past. Recently, populations of M. ethiopica from Europe were re-classified as M. luci, based only on the population isolated from kiwi for Greece. In the current work, the RKN populations originating from kiwi and maize and maintained on tomato, were identified as M. luci. Nematode species identification was determined by electrophoretic analysis of protein extracts obtained from females.

Abstract

This paper investigates the antimicrobial action of Escherichia coli ATCCR CRM-8739TM on the following essential oils: Teucrium marum, Pinus sylwestris, Thymus vulgaris, Salviae aethedaroleum, Cinnamomum aromaticum, Hippophae rhamnoides, Lavandula angustifolia, Abies alba, Zingiber officinale, Anethum graveolens, Coriandrum sativum, Origanum vulgare, extracted industrialy from romanian plants, using the diffusion disc method. The most intense activity was observed at the essential oil of Cinnamomum aromaticum (cinnamon) and the mildest activity was observed at Zingiber officinale (ginger). Many of the essential oils tested exhibited moderate antimicrobial activity, as Teucrium marum, Thymus vulgaris, Hippophae rhamnoides, Lavandula angustifolia,Coriandrum sativum. The lowest antibacterial activity was exhibited on Pinus sylwestris, Salviae aethedaroleum, Zingiber officinale and Anethum graveolens.

Abstract

During two seasons of observations, 244 specimens of hoverflies belonging to 16 species and four trophic groups were collected from herb flowers. Predatory species constituted about 50% of all the registered species and from 55% (2010) to 64% (2011) of all the specimens found. The most numerous flower-visiting species within this group were small, poor flyers, typical of communities with low plants - Sphaerophoria scripta (Linnaeus 1758) (19.6% in 2010 and 23.5% in 2011) and Eupeodes corollae (Fabricius 1794) (13.4% and 12.1%, respectively). Both species were classified to the eudominant group. Syrphus vitripennis (Meigen 1822) and Melanostoma mellinum (Linnaeus 1758) were classed as dominants. Non-predatory saprophagous species from the subfamily Eristalinae constituted about 25% of all collected species; the phytophagous group was scarce represented by Eumerus funeralis (Meigen 1822), E. strigatus (Fallen 1817) and Merodon rufus (Meigen 1838). Of the coprophagous species, only Syritta pipiens (Linnaeus 1758) was collected (6.8-8.0%). There were clear differences between flowers in terms of feeding visits by adult hoverflies. Matricaria chamomilla L. and Thymus vulgaris L. were the most attractive flowers, whereas Origanum vulgare L., Carum carvi L., Lavandula angustifolia L. and Hyssopus officinalis L. were of an intermediate visit status and Ocimum basilicum L. was relatively under-visited.

Abstract

Cardiovascular diseases represent one of the most notable health problems of the modern civilization. Stroke and heart attack often lead to lethal outcome; essential problem underneath being thrombus formation. Prophylactic approaches include acetylsalicylic acid and clopidogrel therapy on the level of primary hemostasis, i.e., primary clot formation. In the last five years, in the USA, health care expenses related to cardiovascular diseases have increased 50 %, to over 350 billion dollars. Thus, application of plant species and medicinal plants rich in polyphenols in prevention of thrombus formation are of interest. This is supported by the fact that the number of publications on antiaggregatory effect of polyphenols has doubled in the last decade. In this review we focus on antiaggregatory effect of most abundant polyphenols – flavonoids, the effect of plant extracts rich in polyphenols (propolis, species Salvia sp., Calamintha nepeta L., Lavandula angustifolia Mill., Melissa officinalis L, Mentha x piperita L., Ocimum basilicum L., Origanum vulgare L., Rosmarinus officinalis L.) on platelet aggregation, association of chemical composition and antioxidant properties with the observed biological effect, and possible clinical significance of the published results.

Abstract

Due to fewer bumblebees in rural areas these days, it is necessary to look for alternative habitats for the active protection of these very important pollinators. The research was carried out in The Botanical Garden of Medicinal Plants, in Wrocław, Poland. In the garden, approximately 2000 plant species were cultivated, of which 185 were visited by bumblebees. Amongst them, 57 plant species were deemed very attractive and were determined to be indicators for 7 bumblebee species. Indicator species for bumblebees ranged between 6 for Bombus pratorum to up to 20 for B. pascuorum. Monarda didyma was an indicator plant to 6 recorded bumblebee species. Other indicator plant species for at least 4 bumblebees species were: Origanum vulgare, Lavandula angustifolia, Rhododendron catawbiense, Phacelia tanacetifolia, and Agastache rugosa. Three bumblebee species were found to forage the most on 11 of the flowering plant species. The biggest group of plants were those which were mostly visited by 1-2 bumblebee species. Amongst all recorded indicator plants, 32% were native species.
