Renewable resources constitute a ‘limited infinity’, meaning that a limited amount is being produced, but for an infinite time.1 One of the most promising approaches to reduce the resource intensity is to use the existing biomass more efficiently: the biorefinery concept. It aims to use the complete biomass and all by-products emitted by the processes. Particularly the by-products of establishe...

Kůdela V., Krejzar V., Pánková I. (2010): Pseudomonas corrugata and Pseudomonas marginalis associated with the collapse of tomato plants in rockwool slab hydroponic culture. Plant Protect. Sci., 46: 1-11. Plant pathogenic species Pseudomonas corrugata and P. marginalis were detected and determined in collapsed tomato plants in rockwool slab hydroponic culture in southern Moravia, Czech Republic...

Iron deficiency chlorosis (IDC) in soybeans has proven to be a perennial problem in the calcareous soils of the U.S. upper Midwest. A historically difficult trait to study in fields, the use of hydroponics in a controlled greenhouse environment has provided a mechanism to study genetic variation while limiting environmental complications. IDC susceptible plants growing in calcareous soils and i...

Rhizogenic Agrobacterium biovar 1 is the causative agent of hairy root disease (HRD) in the hydroponic cultivation of tomato and cucumber causing significant losses in marketable yield. In order to prevent and control the disease chemical disinfectants such as hydrogen peroxide or hypochlorite are generally applied to sanitize the hydroponic system and/or hydroponic solution. However, effective...

Licentiate thesis. ISSN 1652-6880 , ISBN 91-576-7174-5. Rapid pathogen dispersal by circulating nutrient solutions in closed hydroponic systems poses a major threat to this produc...

Cultivation of vegetables with the hydroponic method is able to produce plants better quality values and efficient in land use when compared conventional ones. The comparison regarding production effectiveness nutrient uptake between two cultivation systems appears be little studied. This study aimed determine effect planting on growth romaine lettuce (Lactuca sativa) pakcoy (Brassica rapa) thr...

Thallium (Tl) is a toxic trace element with highly negative effect on the environment. For phytoextraction purposes, it important to know limitations of plant growth. In this study, we conducted experiments model Tl-hyperaccumulating (Sinapis alba L., white mustard) better understand tolerance and/or associated detoxification mechanisms under extreme Tl doses (accumulative 0.7/1.4 mg Tl, in tot...

The objective of this study was to get more information about the root zone, mainly the gas composition in substrates, which are used in closed hydroponic systems. For analyses of carbon dioxide (CO2), ethylene (C2H4) and oxygen (O2) different methods were proved and used. For analyses of carbon dioxide and ethylene, a gas sampling system was used to get gas samples from the root zone. CO2 gas ...
