Opis:: This methodological study evaluated the efficiency of predicting aboveground biomass and grain yield in fieldgrown winter wheat by measuring the saturation root electrical capacitance at anthesis. Three cultivars were grown over a threeyear period as sole crops and intercropped with winter pea at halved wheat density. The root capacitance readings were converted into saturation root electrical capacitance using the relevant soil water content, according to an empirical function. At plant scale, saturation root electrical capacitance at anthesis showed a significant (p < 0.001) linear regression with the total aboveground biomass (R2: 0.653-0.765) and grain yield (R2: 0.585-0.686) at maturity for each cultivar. At stand scale, both the mean saturation root electrical capacitance and shoot dry mass at anthesis and grain yield varied over the years, and were consistently higher for the intercrops compared to the sole crops. The relative increase in saturation root electrical capacitance due to intercropping corresponded with the changes in shoot dry mass and grain yield, especially in dry years. Saturation root electrical capacitance was significantly correlated with shoot dry mass (R2: 0.714-0.899) and grain yield (R2: 0.742-0.877) for each cultivar across all cropping systems and years. In conclusion, by mitigating the soil water content effect, the measurement of saturation root electrical capacitance at anthesis is adequate to forecast grain yield and cultivar response to a changing environment.

Opis:: Six seedling hypocotyl anatomical characters of sugar beet diploid lines and triploid hybrids were measured. Root yield and sugar content of these lines and hybrids were evaluated in replicated field trials. Some of the studied hypocotyl characters: the diameter of the central core, the diameter of parenchymatic cells outside the central core and the width of xylem, correlated negatively with sugar content and positively with root yield. This suggests that these parameters can be used in preliminary selection of sugar-beet breeding material. Introducing such criteria into the breeding process could speed up the selection and reduce the number of expensive field trials.

Opis:: This study examines the influence on growth parameters, in particular the morphological features of the root system, of 1-year-old European beech seedlings cultivated in containers with two different densities. The experiment was conducted in the container nursery in Skierdy (Forest District of Jabłonna) in spring 2011. After 10 months of cultivation in Hiko polyethylene containers, above- and below-ground parts of the seedlings were measured. The measurements of the root system were conducted with a scanner and the WinRHIZO software. No influence due to the seedling density on either shoot height or thickness was observed, but instead the research showed that different seedling densities affected the development of root systems. The mean root thickness and dry mass of the European beech seedlings were significantly higher at the lower density. The influence of seedling density on the development of root mass deserves special attention as it is the most important factor affecting future growth of the seedlings during cultivation. This tendency also suggests that the amount of nutrients allocated to shoot development may be higher in order to improve the efficiency of photosynthesis. At both densities, differences in biomass accumulation affected the root-toshoot ratio. In seedlings cultivated at the lower density, the increased dry root matter of the seedlings resulted in a significant increase in the root-to-shoot ratio. This may cause a potential growth advantage of these seedlings after they are planted and may thus result in a more productive cultivation.
