The percent plant water was determined over a 6-yr period on plants of winter wheat (Triticum aestivum L.) and fall rye (Secale cereale L.) cultivars of a number of yield tests grown on Prince Edward Island. There were year-to-year variations in plant water content within cultivars. A negative correlation was obtained between percent plant water and winterhardiness. Generally, correlations of percent plant water with winterhardiness rating were better than with annual field survival. In some years percent plant water did not correlate with either field survival or winterhardiness rating. Plant water content was correlated with long-term winterhardiness rating during years when little or no winterkilling occurred.Key words: Winter wheat, fall rye, plant water

In two controlled-environment experiments, N fertilizer applied to a Dark Brown prairie soil decreased cold hardiness of winter wheat (Triticum aestivum L.), while P applied in the absence of N had little effect. When applied together, P counteracted the effect of N and produced plants as hardy as those that had received no fertilizer. The soil was rich in K; consequently application of additional amounts of this element had no effect on cold hardiness. The correlation coefficient between dry weight of crowns and cold hardiness (LT50) was not sigificant, but that between water content and LT50 was highly significant.

Four cultivars of winter wheat were analysed for non-structural carbohydrates at four harvest dates starting at inflorescence initiation and ending at anthesis. Grain number was determined from comparable plants harvested at maturity. Fructose, glucose, sucrose, and fructans were quantified in extracts of stems and inflorescences. In stems the content of the four carbohydrates increased until about a week before anthesis. During the week before anthesis the trend for the sugars was variable, but fructan content continued to increase. In inflorescences, trends for sugars were similar to those in stems; however, fructan content peaked 7-10 days before anthesis. Peak quantities of fructans in inflorescences and the quantities degraded after the peak were both correlated with grain numbers. The average degree of polymerisation of fructans from stems was 5 with most being in the range from 3 to 7. The degree of polymerisation in inflorescences ranged from 3 to 56. All of these data indicate that inflorescences differ from stems in their control of fructan metabolism.

In this study the effect of N, P and K nutrients on the Cu and Fe content of winter wheat (Triticum aestivum L.) grains was investigated in a long-term fertilization experiment set up in Nagyhörcsök. Samples were also harvested from four experimental stations of the Hungarian national long-term fertilization trials. These are the following: Bicsérd, Iregszemcse, Karcag, and Putnok. Plant samples were collected in 2005 which was very wet. Our results from Nagyhörcsök were compared with the Cu and Fe content of samples which were harvested from control plots of other experimental stations. The Cu and Fe content of grain samples were measured using inductively coupled plasma mass spectrometer (ICP-MS) followed by digestion with HNO3-H2O2 solution. All data were subjected to ANOVA, and when significant differences (P<0.05) were detected, Duncan’s test was performed to allow separation of means. The main conclusions are as follows: Cu and Fe content of wheat grains was higher and higher in every NPK treatments. Samples were harvested from the control plots of Iregszemcse and Bicsérd have higher Cu content than the treated samples from Nagyhörcsök.

The forage yields of winter wheat (Triticum aestivum L.) and fall rye (Secale cereale L.) when seeded on two dates in the fall and one in the spring were compared under simulated hay and pasture systems. Winter wheat produced higher total yields, but fall rye reached spring pasture and hay maturities 1 and 2 wk earlier, respectively, than winter wheat. When seeded in the spring, both winter wheat and fall rye produced more hay and pasture than when seeded in the fall, and there was a trend toward higher production when seeded in August than September. The hay harvests were more productive than simulated pasture for all systems.Key words: Yield, forage, hay, pasture, winter wheat, fall rye

Cold-hardened crowns of winter wheat (Triticum aestivum L.) and a winter rye (Secale cereale L.) readily dehardened upon exposure to warm temperatures. Crowns dehardened at a faster rate at 20 C than at 10 and 15 C. Dehardened plants were capable of rehardening in a short period of time upon exposure to cold-acclimating conditions. In all the dehardening studies, there was a high positive correlation between cold survival and water content of the crowns. Plants collected in the fall and stored at −2.5 C maintained the same level of hardiness for 17 wk.
