A study of 13 grapevine cultivars was carried out in a vineyard located near Krakow (Poland) in order to identify the most suitable grapevine cultivars for cool climate regions. The vines’ vigour, yield and the yield efficiency index were studied in the years 2010-2013. The grapes were analysed to determine soluble solids content (SSC), titratable acidity, total polyphenol content (TPC) as well...

We investigate the influence on mantle convection of the negative Clapeyron slope ringwoodite to perovskite and ferro-periclase mantle phase transition, which is correlated with the seismic discontinuity at 660 km depth. In particular, we focus on understanding the influence of the magnitude of the Clapeyron slope (as measured by the Phase Buoyancy parameter, P ) and the vigour of convection (a...

Contesting animals typically gather information about the resource value and that information affects fight motivation. However, it is possible that particular resource characteristics alter the ability to fight independently of the motivation. Using hermit crabs, we investigate how the resource in terms of shell quality affects both motivation and ability to fight. These crabs fight for shells...

Seed ageing is influenced by two environmental factors, RH and temperature. The deterioration of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions . Autooxidation of lipids and increase in the content of free fatty acids during storage period are the main reasons for rapid deterioration of seed of oil plants. Accelerated ageing has ...

What attributes make some individuals more likely to win a fight than others? A range of morphological and physiological traits have been studied intensely but far less focus has been placed on the actual agonistic behaviours used. Current studies of agonistic behaviour focus on contest duration and the vigour of fighting. It also seems obvious that individuals that fight more skilfully should ...

Chicory (Cichorium intybus L.) seed production includes sorting to remove foreign materials and non-viable seeds. A machine vision system was developed to monitor the fluorescence in order to detect the immature chicory seeds. It comprised a monochromatic light source, a highpass filter and a monochromatic CCD camera sensitive to red and infrared. With this device, blue light reflected by the s...

Experiments were conducted to investigate the effects of low power microwave radiation on germination and growth rate in seeds. In the present paper, the bioeffects of low power (non-thermal intensity) microwave modulated with 1 KHz square wave have been studied. Experiments were performed in X-band frequencies using klystron based microwave test bench. Microwave parameters like frequency, powe...

Climate shifts at decadal scales can have environmental consequences, and therefore, identifying areas that act as environmental refugia is valuable in understanding future climate variability. Here we illustrate how, given appropriate geohydrology, a rift basin and its catchment can buffer vegetation response to climate signals on decadal time-scales, therefore exerting strong local environmen...

introduction during the last decades interest in organic production of seed specially for medicinal plants take into consideration because of higher quality of organic products (hermes, 2010). seed germination is one of the principal stages in the plant life cycle and seeds with higher quality and vigour resulted in more pronounced seedlings growth and development. therefore, investigation of a...

A study had been conducted in black gram to observe the effect of different seed invigoration treatments with bio-priming for germination, seedling growing and vigour. The variety i.e., Uttara, was selected treated control (T1); Seeds soaked distilled water/ hydropriming (T2); Rhizobium leguminosarum 10% (T3); 15% (T4); 20% (T5); 25% (T6); 30% (T7) respectively. Treated seeds were grown glass p...
