Effect of Some Plant Oils on Biological, Physiological and Biochemical Aspects of Spodoptera littoralis (Boisd.).
Jojoba oil sesame oil Spodoptera littoralis
2010/11/12
Jojoba and Sesame oil extracts were used in this work to evaluate their effects on biological,
physiological as well as biochemical changes of the cotton leafworm Spodoptera littoralis (Boisd.). Both...
Acoustic emission as a method for the detection of fractures in the plant tissue caused by the external forces
acoustic emission stress strain plant tissue
2008/11/26
In order to detect fractures in the plant tissue resulting from deformations, the method of acoustic emission has been applied. Simultaneous measurements of the mechanical parameters and the acoustic ...
Analysis of plant tissue images obtained by confocal tandem scanning reflected light microscope
structural parameters of plant tissue image analysis confocal microscope
2008/11/26
The paper presents two methods (automatic and semi-automatic) for quantitative evaluation of cell structural parameters of plant tissues. The methods were developed for images obtained by confocal tan...
Analysis of the interrelation between the heat balance structure, type of plant cover and weather conditions
heat balance evapotranspiration latent heat sensible heat Bowen ratio
2008/11/26
There are many ways of micrometeorological description of the environment. One of them is the analysis of heat balance of an active surface which characterizes very well areas with different plant cov...
Drying parameters of plant-fish feeding concentrates in drum driers
drying fish plant concentrate
2008/11/24
Lack of literature data relating to the parameters of drying the plant-fish feedstuffs in industrial hot-air and contact drum driers was the reason for un- dertaking this research. Its purpose was to ...
Influence of application of plant growth regulators and desiccants on a yield and quality of winter oilseed rape
oilseed rape varieties plant growth regulators yield quality
2008/11/24
The purpose of the conducted researches was an estimation of influencing of application of growth regulators (metconazole, di-1-P-menten, dimethipin) and desiccants (diquat, glyphosate) on a yield and...
Influence of groundwater depth and available soil water on evapotranspiration and plant growth
actual evapotranspiration plant available soil water dry matter yield cropland grassland coniferous forest
2008/11/24
There is a close relationship between available soil water and water consumption as well as plant growth if we assume adequate soil aeration. Transpiration and plant growth increase with an increasing...
Interaction of individual surface microridges in the course of friction between construction walls and plant material
friction single surface microridge
2008/11/24
The paper presents the analysis of a typical example of plastic micro-contact in the course of mutual slide of processed vegetative material and construction surface. One of the theories of border loa...
Destruction processes in the cellular medium of a plant theoretical approach
damage of the cellular body crack propagation in the plant tissue
2008/11/21
A theoretical model of destruction of a material containing elastic cell wall surrounding a content consisting of liquid and gas is presented. The results show that a damage of the cellular plant mate...
Exchange of water in the soil-plant-atmosphere system
soil-plant-atmosphere system exchange of water
2008/11/21
The developed methodology (the scaling procedure) was shown how to solve the problems effluxes and of soil water storage in systems with heterogeneous soil-plant-atmosphere boudary.
We used information theory methods to analyze the process of primary soil formation in a model soil-plant system with the permanent cultivation of plants under controlled conditions. When studying the...
Quantitative method for determining cell structural parameters of plant tissues
cell structural parameters image analysis parenchyma tissue of potato tuber
2008/11/18
The present work focuses on a method for quantitative evaluation of cell structural parameters of plant tissues such as: surface area, perimeter, Feret's diameters, elongation. The method is based on ...
Influence of plant cover on the share of the soil heat flux in the heat balance of the active surface
heat balance soil heat flux leaf area index
2008/11/14
Soil heat flux is one of the heat balance components of active surface. Average value of this flux for a long period is equal zero, but for a short period it can be very high. It can be positive, when...
Investigations of plant infections by thermal vision and NIR imaging
infrared imaging transpiration plant discrimination fungi infections
2008/11/14
The successful applicability of thermal vision in horticulture was the starting point to launch a project in plant protection. Earlier studies proved the applicability of thermal vision for the assess...
