Ac cording to the pollen spectra found, most of them are multifloral (27); 22 samples were monofloral. The monofloral honeys were Erica type followed by Centaurea, Reseda, Onobrychis, Rubus, Cytisus and Hederá. 126 different pollen types were recorded, be longing to 41 families. 53 of them reached percentages over 3% in some samples. The other 73 types did not reach percentages over 3% in any of the 49 samples. The families present in the highest number of samples were: Fabciceae, Asteraceae, Cistaceae and Rosaceae\ the families that had the highest percentages were: Fabaceae, Asteraceae, Ericaceae and Rosaceae. The pollen types that appeared in the most samples were: Papaver rhoeas (39 samples) and Rubus ulmifolius (38); the pollen types that reached the highest abundance percentages were: Erica arbórea, Onobiychis viciifolia and Reseda luteola. The pollen types of Ericaceae and Lavandula latifolia can be used as indicators in order to know the zone of origin zone of honeys produced in Palencia, and it allows us to detect any possible commercial frauds concerning the origin of honeys.

The aims of the study were to measure nutrient concentration variations along the productive cycle in both treatments, to clarify the differences regarding fruit yield and to assess recycling system viability. Emitter and drained nutrient solution samples from both treatments were analyzed once per week, tomato samples were collected three times per week and they were measured and weighed. It was concluded that the average nitrate concentration in the inlet of the recycling treatment was 11.60 meq/l. The concentration increased by 7.01% in the leachate solution. The average sulfate concentration was 8.07 meq/l in the recycling system supplied solution, and 146.47% higher in leachates. Three analyzed nutrients, i.e. phosphate, potassium and ammonium, presented a lower concentration in the drained solution than in the supplied solution. Fruit yield was not increased by the recycling technique in the hydroponic crop. Recycling treatment viability has to be measured in terms of water and fertilizer savings and minimization of polluting waste in drainage solutions.

A volumetric trap was used. We collected daily samples of aerovagans spore from the atmosphere through a cellulose esther filter, half of which was cultivated on Petri dishes. The following genera were identified: 26 Deuteromycetes (54%), four Zygomycetes (28%), and three bacteria, which along with Actinomycetes, reached 18% of all the registered colonies. Fifty-two percent of the colonies were developed in Czapecdox culture medium and 48% in Sabouraud medium. Most of the bacteria were grown in Sabouraud medium. The highest number of colonies recorded belonged to the following three genera: Mucor (25%), Aspergillus (23%) and Penicillium (16%). Most colonies were grown in autumn (32%), while spring was the second most frequent season when 28% of the colonies were registered.

All populations show between 18 and 26 alleles. Genetic distance (D) was 0.123. Diversity parameters show similar or higher levels compared to other autogamous plant populations. They show an heterozygote defect. Coefficient of homozygotes among populations (G ST) value 0.414, was similar to Inbreeding coefficient among populations (F ST) that was 0.454. Main component analysis showed that the most important isozymes in the characterization process were GOT-3 and PGM-2. Four groups of populations were obtained by cluster analysis. This information reveals new data for improving their use in the germplasm banks for crop programs.

Samples of 12 wild populations of the Lavandula genus collected between 2009 and 2010 were hydrodistilled and their by-products were analyzed using the FolineCiocalteu, free radical scavenging activity (2,2-diphenyl-1picrylhydrazyl), and the ferric reducing antioxidant power (FRAP) methods. Rosmarinic acid, apigenin, and luteolin contents were analyzed by high-performance liquid chromatographyediode array detection. The mean of total phenolic content ranged from 1.89 ± 0.09 mg gallic acid equivalents/g dry weight to 3.54 ± 0.22 mg gallic acid equivalents/ g dry weight. The average value of the half maximal effective concentration (EC 50) for scavenging activity ranged from 5.09 ± 0.17 mg/mL to 14.30 ± 1.90 mg/mL and the variability of the EC 50 in FRAP ranged from 3.72 ± 0.12 mg/mL to 18.55 ± 0.77 mg/mL. Annual variation was found among this samples and the environmental conditions of 2009 were found to be more favorable. The plants collected from Sedano showed the highest antioxidant power. Our results show that rosmarinic acid and apigenin in L. latifolia contributed to the antioxidant properties of the waste. In conclusion, the by-product of the distillation industry could be valorizing as a source of natural antioxidants.

L. is an endemic species of the Iberian Peninsula and one of the most collected of wild plants in Spain. Despite the huge amount of possibilities for the use of T. mastichina subsp. mastichina as an industrial crop, cultivation is almost absent and no selection has been made. To identify the most useful and discriminating traits and to study the morphological variability of Spanish marjoram, a total of 16 populations were studied during 2011 and 2012 and 20 morphological traits (15 quantitative and 5 qualitative) were used for characterization. Analysis of variance, principal component analysis, correlations among traits and cluster analysis have been carried out for data processing. Intra and inter-population variability were highly statistically significant for all the quantitative traits, revealing the polymorphism of the species, although variability among populations was greater than variability within populations showing that populations are morphologically distinguished from each other. Number of flowers per flower head, number of flower heads per branch, length/width of the bract, and bract width were the most variable traits. The most valuable traits for characterization were related to the bract form and size, leaves and capitula. The ranges of morphological variation for the cultivated specimens compared with references to wild specimens in the bibliography, showed slightly larger sizes of leaves, bracts and inflorescences and smaller sizes of calyces and corollas. Cluster analysis classified the populations into four groups. Populations from group three (CLM4, TM23 and TM43) were highlighted by the biggest flower heads and they may be more productive for essential oil extraction.

As a result, high morphological variability has been described constituting a very polymorphic taxon. Despite its cultivation potential for essential oil production, the lack of standardized and well-characterized plant material has hindered its agronomical production. In our study, 12 wild populations previously selected by their essential oil yield and general appearance have been propagated and cultivated during three years (2013-2015) in two different experimental fields. 13 morphological traits regarding leaves, inflorescences, bracts and flowers were yearly measured in the same individual specimens. The cultivated material has shown phenotypic stability in the two different environments and during the three years of testing. However, intrapopulation and, above all, inter-population variability have been detected. The studied populations were clustered in four groups by mean of multivariate statistical analysis. Clusters were distinguished by leaf size, inflorescence shape, number of flowers in the second verticillaster from the top and bracts dehiscence or not, and presented a consistent geographical distribution since geographically-closer populations were grouped into the same cluster. Population P5 (Guixers) stood out by its remarkable leaf size under cultivation conditions (6.8-9.7 cm length, 2.1-3.0 cm width), much higher than that previously reported for

The study was carried out by conducting semi-structured interviews of 50 residents above the age of 52. The total number of use reports was 2,879; 839 refer to plants used in human food and 247 are related to plants used in animal feed. Forty-two wild species have been cited for human consumption: 45.2% of them are exploited for their fruit, 33.3% are eaten as vegetables, and 28.6% are used to produce liqueurs. Twenty wild species have been cited as animal feed, six of which are also used as food for human consumption and 90% as fodder or hay. Of the species, 20% are used for their fruit, whether fresh or dried. The species of the highest interest for human consumption in the region were Corylus avellana, Prunus spinosa, Fragaria vesca and Sorbus aria. The plants that were cited most often as animal feed are Asphodelus albus, Quercus petraea and Q, pyrenaica. Conopodium pyrenaeum, locally called ajuérjano in Spanish, a common name unique to the region ("pignut" in English), was cited by more than 50% of interviewees. Conopodium majus is consumed in nearby regions. Conclusion: Wild food plants gathered in the region are not the population's main source of nutrients, but they are important resources that can be used to diversify recipes.

Abstract Essential oils of 11 populations of Thymus mastichina (L.) L., 10 populations of Salvia ... more Abstract Essential oils of 11 populations of Thymus mastichina (L.) L., 10 populations of Salvia lavandulifolia Vahl and 12 populations of Lavandula latifolia Medik., collected in full bloom during 3 years (2009–2011) were analyzed by gas chromatography (GC)-flame ionization detector (FID) and mass spectrometry (MS) to study the variability among populations and the influence of the year of harvest in the essential oil composition. One factor ANOVA for population origin and year of harvest, and Principal Component Analyses (PCA) using the main compounds as set of observations were carried out for each species. For T. mastichina all the samples were 1,8-cineol chemotype (58.52–68.82%), however the linalool content showed a great range of variation (1.16–10.24%). 1,8-Cineol (6.21–33.69%), camphor (2.85–22.44%) and β-pinene (5.11–19.85%) were the main compounds for S. lavandulifolia and 1,8-cineol (30.57–54.09%) and linalool (15.82–45.94%) for L. latifolia essential oils. Populations from T. mastichina and S. lavandulifolia from different years appeared mainly grouped in the PCA figures while L. latifolia populations showed no clustering. T. mastichina was the least environmentally influenced species, showing mainly differences among populations. S. lavandulifolia also had small differences among campaigns and higher differences within populations. Conversely, L. latifolia showed a higher percentage of differences in the volatile composition depending on the year of harvest but genotypic variability was also observed. In conclusion, the variability of the essential oil composition is largely dependent on the population studied having genetic factors a greater influence than the environmental factors. However, environmental factors are also influencing the essential oils composition and must be taken into account.

Introduction and main objectiveBursaphelenchus xylophilus, commonly known as pine wood nematode (... more Introduction and main objectiveBursaphelenchus xylophilus, commonly known as pine wood nematode (PWN), is considered one of the greatest threats to European and Asian pines. Regarding its management, most efforts have been directed toward control measures for the major vector (Monochamus spp.) and screening for genetic resistance in its hosts. However, an integrated pest management strategy which also implements pinewood nematode control is currently lacking. The aim of this study was to evaluate the nematicidal effect of two Beauveria species, a genus well known for its entomopathogenic activity.Summary methodologyFor this purpose, in vitro antagonism tests of fungi (Beauveria bassiana and B. pseudobassiana) and the mycotoxin beauvericin (C45H57N3O9) on B. xylophilus populations were conducted. Finally, the production of beauvericin in B. bassiana and B. pseudobassiana strains was quantified by high-performance liquid chromatography - mass spectrometry (HPLC-MS).Results and discuss...

(stone pine) seedlings in abandoned cropland. Ninety seedlings were randomly selected. In half of them weeds were removed and the remaining 45 were not treated. The research lasted from November 1998 to October 1999. The studied area was located 7 km from Palencia city (Northern Spain). The pine trees were planted in ridges. Weed mean cover around the untreated seedlings was 12.38%. Greatest height growth in pine seedling occurred in April. Significant differences were observed between different treatments. Weeds reduce the height of the pine trees, although the effect was not very remarkable. There was a significant negative relation between tree diameter and weed. The average growth of the pine trees regarding height was 24.44% and 50.14% regarding diameter. In general, there was more growth in the diameter than in height, because the reforested species consume more energy...
