The rate of water imbibition by wheat kernels may be related to preharvest sprouting damage and tempering times during milling. The effects of kernel color and exposure to weather damage on water imbibition rate of wheat (Triticum aestivum L.) kernels, and the effects of field vs. oven drying and hand vs. mechanial threshing on water uptake rate of HY320 wheat and Welsh triticale (X-Triticosecale Wittmack) were investigated. Rates of imbibition were determined by sequential weighings over a 32-h period of 50-kernel samples imbibing water from agar media. In HY320 wheat, the rate was faster for mechanically threshed (0.0117 g g−1 h−1) than for hand-threshed (0.0115 g g−1 h−1) samples. Threshing method did not affect imbibition rate of Welsh triticale kernels (average 0.0141 g g−1 h−1). Rate of germination was significantly greater for mechanically threshed than for hand-threshed Welsh, but there was no significant difference for HY320. Method of drying did not affect kernel water imbibition rate. Rate of imbibition was faster in nonweathered than in weathered wheat (0.0136 vs. 0.0130 g g−1 h−1). In five wheat crosses involving white and red kernel color, rate of water imbibition was not associated with the allele for kernel color. Rate was negatively correlated with kernel weight (r = 0.49**, n = 49) and kernel hardness (r = −0.29*) in the five crosses, and positively correlated with protein content (r = 0.44**). Other undetermined factors accounted for the major part of the genotypic differences in rate of imbibition.Key words: Triticum aestivum L., X-Triticosecale Wittmack, windrowing, kernel water imbibition rate, germination rate

Several traits have been measured as indices for winter hardiness in winter wheat (Triticum aestivum L. em. Thell). Published information on the response of winter triticale (X Triticosecale Wittmack) to these traits is limited. In this study LT50, water content, fresh weight, dry weight and total soluble carbohydrate (TSC) were determined for cold acclimated crowns of 10 breeding lines of T. aestivum and 18 of triticale. The T. aestivum lines evaluated were hardier than the triticale and LT50 appeared to be a reliable predictor of field survival (FSI). Correlations between LT50 and FSI were significant for both species. Correlation coefficients between traits measured differed between species. In triticale, correlations between dry weight, water content and LT50 were significant. In T. aestivum water content correlated closest with LT50. The relationship between TSC and FSI appeared to differ between the two species.Key words: X Triticosecale Wittmack, Triticum aestivum L. em.

Ten genotypes of barley (Hordeum vulgare L.) and 10 genotypes of wheat (Triticum aestivum L.) were grown with four types of plot borders (control, same genotype as the plot; unbordered; winter wheat; spring barley/wheat) to study the influence of plot borders on the ranking for yield of cereal genotypes. Plot yields increased as border competition decreased. However, the ranking of the different genotypes was not influenced by the type of plot border, except when a highly competitive barley genotype was used as a border with wheat. It was concluded that the type of plot border was of relatively little importance in selection for yield, as long as the border was not more competitive than the plot.Key words: Barley, wheat, plot borders, yield, plant competition, varietal ranking

W zbożowych kulturach in vitro jednym z najtrudniejszych problemów do przezwyciężenia w trakcie produkcji podwojonych haploidów (DH) jest albinizm. Wydaje się, że dość skutecznym sposobem redukowania albinizmu jest dobór odpowiedniego czynnika stresowego w połączeniu ze zbalansowanym składem pożywek. W prezentowanej pracy zastosowano suplementację pożywek jonami miedzi i srebra (CuSO4, AgNO3) oraz modulowano czas kultur na pożywkach indukujących dla trzech gatunków zbóż: jęczmienia (Hordeum vulgare L.), pszenicy (Triticum aestivum L.) oraz pszenżyta (x Triticosecale spp. Wittmack ex A. Camus 1927). Zastosowanie metody Taguchiego pozwoliło na ograniczenie liczby eksperymentów oraz umożliwiło zoptymalizowanie warunków prowadzenia kultur in vitro, co ostatecznie wpłynęło na poprawę ilości zielonych regenerantów u wszystkich zastosowanych gatunków.
