Control of plant growth is an important aspect of crop productivity and yield in agriculture. Overexpression of the At CHR12/ 23 genes in Arabidopsis thaliana reduced growth habit without other morphological changes. These two genes encode Snf2 chromatin remodelling ATPases. Here, we translate this approach …

Plants are sessile organisms that deal with their -sometimes adverse- environment in well-regulated ways. Chromatin remodeling involving SWI/SNF2-type ATPases is thought to be an important epigenetic mechanism for the regulation of gene expression in different developmental programs and for integrating …

It all began with ̈Celebration® Karneval® ̈ from Westhoff, a Calibrachoa mix consisting of three different colours. The result in red, yellow and blue was so convincing that it became the trend-setter for what nowadays is marketed under the name "combi-pots". These are colourful combinations, either …

This thesis is an overview of the market and management for WEEE (waste of electrical and electronic equipment) in Bulgaria. It was executed to answer certain questions to WEEE Forum, which was my internship provider. Chapter 2 analyzes the WEEE market and business developments in Bulgaria. Chapter 2.1 …

The objective of this study is to apply a potato model for the Andean Ecoregion and extend this model with Late Blight epidemiology and fungicide spray scheduling in order to evaluate effects (trade-offs) of fungicide applications on potato yield.

Field experiments were carried out in 1991 and 1992 on sandy soil highly infested with the potato cyst nematode Globodera pallida. Half the trial area was fumigated with nematicide to establish two levels of nematode density. Three levels of soil compaction were made by different combinations of artificial …

Growth curve analysis of sedentary plant parasitic nematodes on different hosts and at different population densities is used to assess plant suitability including their resistance and tolerance. The estimated parameters of host suitability can be used in pest management programs for economic important …

A bacterium belonging to the Bacillus firmus/lentus-complex and capable of growth on native potato starch was isolated from sludge of a pilot plant unit for potato-starch production. Utilization of a crude enzyme preparation obtained from the culture fluid after growth of the microorganism on native …
