Influence of frequent magnetic field on chlorophyll content in leaves of sugar beet plants
Chlorophyll content in plant leaves is correlated with the yield and nitrogen content in plants. Non-destructive investigations of chlorophyll content in leaves of 3 varieties of sugar beet grown from seeds revealed that a low frequent magnetic field, acting independently or in combination with other methods of seed improvement, increased chlorophyll content in leaves of the investigated plants. The treatment with the magnetic field increased nitrogen content in the examined plants. The effect was not connected with environmental conditions during vegetation seasons
The influence of low frequency magnetic field upon cultivable plant physiology
The 16 Hz frequency and 5 mT magnetic flux density as well as alternating magnetic field influence the field germination physiological yield-forming features and the yield of sugar have been investigated. The profitable influence of the investigated factor at physiological yield-forming features, causing an increase in sugar beet root and leaf yield, was shown. The beneficial influence on the yield is especially clear in unfavourable weather conditions
The influence of low-frequent magnetic field on seed germination at low temperature
The influence of 16 Hz and 50 Hz frequent magnetic field on the germination of seed of different agricultural crops (spring wheat, soybean and maize) under the stress condition (temperature 5掳C or 10掳C) was examined. The acceleration of germination and decrease of Pieper'si coefficient of seeds treated with frequent magnetic fiels in comparison with untreated seeds was found
Mo偶liwo艣ci poprawy warto艣ci siewnej nasion miskanta chi艅skiego (Miscanthus sinensis Andersson)
Miscanthus sinensis (Andersson) is a perennial grass producing high amounts of biomass. I It can be used for energetic purposes through burning or biogas production. A main problem in this crop cultivation consists in vegetative, expensive method of propagation. First preliminary research on seed quality improvement is carried out in order to enable propagation on a large scale. The object of presented experiment was to find out the reason for low germination ability and to search methods of seed quality improvement. Miscanthus seeds were treated with sodium hypochlorite, commercial micronutrients seed fertilizer and commercial bacteria seed treatment, ash and plasma. The ability and speed of germination and root and shoot length were measured. Tetrazolium test and microscopic observations of seeds were done. Fragility and susceptibility to damage and low vitality of embryos mean that further work is needed on the genetic characteristics and methods of seed harvesting as well as postharvest processing of this species.Miskant chi艅ski jest wieloletni膮 traw膮 wytwarzaj膮c膮 du偶e ilo艣ci biomasy.

Dost臋pno艣膰 i jako艣膰 ekologicznego materia艂u siewnego na przyk艂adzie wybranych gatunk贸w warzyw
Ecological seed is very necessary, but its quality is often much lower than of conventional seeds. The aim of the study was to compare the sowing value of organic seeds of different vegetable species with their conventional equivalents. The research was carried out on the seeds of lettuce, cucumber, spinach and beet from PlantiCo (Zielonki, Poland). The seeds were sown under laboratory conditions in the containers lined with blotting paper and on Petri dishes to observe the course of germination and in soil to observe the emergence process. The weight of one thousand seeds of each species and type was estimated, and the price-seed ratio in the package was established. In general, conventional seeds were characterized by a higher sowing value and a mass of thousand seeds as compared to their organic equivalents. The differences in quality depended on the species. The quality of organic lettuce seeds was the lowest. There was also a high percentage of damages seeds of organic cucumber (10%).Ekologiczny materia艂 siewny jest bardzo poszukiwany, lecz jego jako艣膰 cz臋sto odbiega od warto艣ci siewnej nasion konwencjonalnych.
