Flooding is an important factor, decreasing Allium cepa bulb yield and quality. A comparison, in terms of biometrical biochemical parameters, five cultivars, grown at two different locations, characterized by contrasting conditions water availability, i.e., precipitation excess the end (A) or beginning (B) plant growth, revealed a significant decrease weight, height, diameter, increase oxidativ...

the investigations were carried out in 2007 on the fruit of 7 native early-ripening apple cultivars grown in karaj climatic conditions, harvested in two phenological stages of maturity and ripenning. the harvested samples were stored at (0 ± 0.5) c and (85 ± 5) % of humidity. the measured sensorial traits consisted in: aroma, flavor, sweetness, flesh quality and general acceptability achieved ...

In the past few years there has been a resurgence of interest in the possibility of detecting climate change using natural systems (see, for example, Crick and Sparks 1999; Sparks and Menzel 2002; Hughes 2003; Parmesan and Yohe 2003; Root et al. 2003). The study of recurring natural (or biological) events, often in relation to climate, is known as phenology. These studies typically record event...

we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...

Phenology is an indicator of the impact of climate on vegetation. As the representation of human activities, urbanization affects vegetation phenology by changing the local climate such as temperature, humidity, wind speed, etc. Recent studies starts to focus on the impacts of urbanization intensity on phenology. In order to understand the relationship between urbanization intensity and phenolo...

Phenological changes within a growth season were investigated in two grazed, seminatural grasslands in southern Sweden. On four occasions during the growth season, two independent observers recorded plant frequency and percentage cover. The vegetation data sets were analysed with ordination methods. The temporal changes were highly significant, but accounted for only a small part of the total v...

In the context of defining a procedure for near real time land use/land cover (LULC) mapping with seasonal updated products, this research examines the use of time-series and phenological indicators from MODIS NDVI. 16-day NDVI composites from MODIS (MOD13Q1) covering the period from 2001 to the present were acquired for three test sites located in different parts of Europe. The newly proposed ...

Understanding and interpreting the temporal variations of the vegetation growth can provide valuable information on its dynamics and in case of crops provide an estimate of the phenological milestones that can help describe the crop. The focus of this work is to use the phenological parameters derived from MODIS EVI time series composite data to map the variability in cropping practices. These ...
