Pisum sativum L., as well as many other grain legumes has high agronomical importance connected to their use in crop rotations. Color, size and shape of seeds are very important in grading system for many crops. A total of 33 morphometric and colorimetric features of seeds of five Czech pea varieties, cultivated in four different Czech localities, were measured by image analysis and used to identify and discriminate the varieties also regarding to their cropping localities. The achieved data were used to develop a statistical classifier based on two sample sets, the training set to teach the classifier and the test sets to validate it, and determine the percentage of varietal identification. The developed image analysis system for pea seeds was able to highlight : 1) differences among varieties, 2) the effect of locality on pea seeds traits, 3) different stability of variety.
Linie přadného lnu AGT 876/08 vykazuje zvýšený obsah kyseliny olejové ze standardních 15% na 29%. Linie AGT 876/08 v obsahu mastných kyselin neštěpí a zvýšená hladina kyseliny olejové není závislá na ročníku. Linie AGT 876/08 má hnědé semeno, HTS je 5,6 g.
Cílem metodiky je předložit šlechtitelské, množitelské a pěstitelské praxi metodiky pro snížení výskytu námelovitosti. Doporučené metodické postupy vznikly na základě studia příčin a vlivů, které způsobují vyšší výskyt sklerocií námele v porostech žita.
AGT 578/03 se vyznačuje nízkým obsahem antinutričních látek (kyanogenních glykosidů) v semeni ve srovnání s registrovanými odrůdami olejného lnu v ČR.
The possibility of use of two technological types of Linum usitatissimum L., namely flax (grown for fibre) and linseed (grown for seed), for phytoextraction of cadmium (Cd) from Cd-contaminated soil was studied. A four-year field-simulated experiment was carried out with 6 flax and 4 linseed cultivars in order to study organ accumulation of Cd by flax and linseed plants at artificial concentration range 10 to 1000 mg Cd . kg-1 soil. The most Cd was accumulated by roots, followed by shoots, while reproductive parts (capsules and seeds) played comparably smaller role. The increasing soil Cd concentration resulted in increasing Cd accumulation by roots, while transport to above-ground plant parts was progresivelly inhibited. Even high soil Cd concentrations (1000 mg Cd . kg-1 soil) had not dramatic negative effect on plant growth and development.differences as well as the differences between both technological Linum types have been found in Cd accumulation (flax being better Cd accumulator than linseed). Nevertheless, the recorded variation between technological types and within is in multiples of Cd values (units of mg Cd . kg-1 DW), not in as needed for practical phytoextraction. A significant year-to-year effect on plant growth/development resulting in high variation in Cd accumulation was observed. Further, the contrasting in total Cd accumulation (high accumulating flax cv. Jitka versus low accumulating linseed cv. Jupiter) were selected for future experiments. The uptake of Cd by flax/ linseed from ha per season was calculated and the strategy for flax/linseed growing on heavy metal polluted soils with subsequent utilization of heavy metal-contaminated biomass is discussed.
Jedná se o unikátní směs dvou mykoparazitických půdních hub Clonostachys rosea (kmen SCL-01) a Trichoderma asperellum - harzianum (kmen ASPH). Směs obou hub vytváří kulturu označenou GXT-08, uloženou v chráněném a bezpečném uložení v České sbírce mikroorganismů CCM v Brně. Obě komponenty směsi jsou snadno kultivovatelné jak na tekutých, tak i na pevných (agarových) živných půdách a jsou vhodné k výrobě biopreparátu s využitím submersních i povrchových metod masové kultivace.
