U strukturi sjetve žitarica heljda u Hrvatskoj zauzima najmanje površine. Zbog visokih nutritivnih vrijednosti sve su veće potrebe za heljdom na tržištu. Globalne klimatske promjene ukazuju potrebu odabira norme svrhu ostvarivanja prinosa dobre kakvoće. Tijekom 2019. godine provedena poljska ispitivanja o visini i kakvoći sjemena s različitim varijantama postrne sjetve. Korištene sljedeće varij...

in order to investigate of the effects of water stress on seed yield and gas exchange and to evaluate the relationship between source and sink in sunflower azargol variety, a split-plot factorial field experiment was conducted in 2008. in this experiment, water stress (no irrigation from 30 days after sowing till ripening) and irrigation (irrigation at -3 bar soil water potential) were consider...

Turbulence dynamo deals with amplification of a seed magnetic field in a turbulent medium and has been studied mostly for uniform or spatially homogeneous seed magnetic fields. However, some astrophysical processes (e.g. jets from active galaxies, galactic winds, or ram-pressure stripping in galaxy clusters) can provide localized seed magnetic fields. In this paper, we numerically study amplifi...

The relationships between various carbohydrate pools of the soybean (Glycine max [L.] Merrill) fruit and growth rate of seeds were evaluated. Plants during midpod-fill were subjected to various CO(2) concentrations or light intensities for 7 days to generate different rates of seed growth. Dry matter accumulation rates of seeds and pod wall, along with glucose, sucrose, and starch concentration...

Seed priming is a technique which is potentially able to promote rapid and more uniform seed germination and plant growth as well. In this regards, the presowing effects of seed priming treatments were investigated on some physiological viz. seed germination, germination rate, radicle elongation, shoot elongation, radicle dry weight, shoot dry weight and vigor index. Seeds were subjected to two...

BACKGROUND AND AIMS Pathogen-seed interactions may involve a race for seed resources, so that seeds that germinate more quickly, mobilizing reserves, will be more likely to escape seed death than slow-germinating seeds. This race-for-survival hypothesis was tested for the North American seed pathogen Pyrenophora semeniperda on seeds of the annual grass Bromus tectorum, an invasive plant in Nort...

BACKGROUND: Nutrient management plays an important role for obtaining satisfactory yields and to increase crop productivity. Also keep soil moisture under drought stress is an important factor to produce economical production, so super absorbent polymer has great role to achieve mentioned goal. OBJECTIVES: Present study was conducted to evaluate the effect of ...
