Alfalfa (Medicago sativa), rape (Brassica napus) and barley (Hordeum vulgare) were grown in a growth chamber with and without sulphur (S) on surface samples (0–15 cm) of 17 eastern Canadian prairie soils. The soil varied in pedological origin and were divided into three groups based on their total nitrogen:total sulphur (N:S) ratios. Herbage yield of alfalfa (full bud) and rape (flowering) were highly correlated (P < 0.01) with soil (N:S)s ratios and soil SO4-S, while for barley (shot blade) the relationships were significant [Formula: see text]. Herbage yields of the three crops were also significantly correlated [Formula: see text] with plant (N:S)p ratios. Soil (N:S) ratio was considered the best predictor of herbage yield because it is more stable over time than soil SO4-S and because plant (N:S)p ratio only indicates a need for future fertilization. The highest yields and S and N composition of plant tissues were obtained on soils with SO4-S concentrations greater than 12 mg kg−1 and an (N:S)s ratio of approximately 6. These soils had sufficient S to meet the requirements of all three crops. Addition of S had no effect on herbage yield but did increase S uptake. Results indicated that soils with (N:S)s ratio of 9 and SO4-S concentration of 7 mg kg−1, may have sufficient S to meet the requirement of barley but not alfalfa and rape. However, soils with higher (N:S)s ratios and lower SO4-S content were deficient in S for all crops. Barley was the most responsive to applied S of the three crops, although it had the lowest concentration of S (0.15 mg S g−1 dry herbage) and highest plant (N:S)p ratio (16) at its highest yield. Rape was more responsive to applied S than alfalfa but the concentration of S in the herbage of both crops at their highest yields were similar, 0.27 and 0.26 mg S g−1 dry herbage, respectively. Both crops also had lower (N:S)p ratios than barley at the highest yield (14 (alfalfa) and 12 (rape)), reflecting their greater S uptake. Key words: Plant-available S, soil (N:S)s ratio, plant (N:S)p ratio, plant uptake of S, plant uptake of N

Tests were conducted at Lacombe, AB, from 1989 to 1991 to determine the forage yield and quality of Wapiti triticale (× Triticosecale Rimpani Witt.) grown as a monocrop and in binary mixtures with Cascade oat (Avena sativa L.), Empress barley (Hordeum vulgare L.) or Johnston barley. The Cascade monocrop and mixtures with Wapiti had the highest DM yields (12.37–13.42 t ha−1). Yields of the barley monocrops and mixtures with Wapiti (6.60–9.10 t ha−1 in 1989 and 8.96–11.49 t ha−1 in 1990) were similar to the Wapiti monocrop (8.06 and 8.99 t ha−1). In 1991, yields for the Wapiti monocrop and 25:75 barley:Wapiti mixtures (14.54 and 14.99 t ha−1, respectively) were higher than those for the barley monocrops and 50:50 and 75:25 mixtures (11.98–12.79 t ha−1). The yields of the mixtures in 1989 and 1990 were 108 and 106% higher than expected based on the yield of the components, although in 1991 this enhancement was not observed. Moisture contents at harvest were variable and not always as expected based on the relative maturities of the species. However, mixtures with Wapiti could offer some flexibility in harvest for silage production. Protein contents were found to be highly variable and no trends were established. The Cascade monocrop and mixtures had the highest protein yields in 1990 and 1991. The acid detergent fibre (ADF) contents of the 50:50 and 25:75 Cascade:Wapiti mixtures (26.9 and 28.4 g 100 g−1) were lower than the Cascade monocrop (33.6 g 100 g−1). Lignin contents were found to vary between treatments only in 1989 when the Wapiti monocrop (3.90 g 100 g−1) was intermediate to the Empress (3.30 g 100 g−1) and Cascade (4.83 g 100 g−1). Yield stability and quality would make use of Wapiti mixtures for silage attractive choices for silage production. Key words: Silage, protein, ADF, lignin, cereal mixtures

Genotype by environment interaction and stability analyses are among the most important evaluations conducted in plant breeding. In this study, we evaluated the yield-related traits of 32 Tunisian barley (<em>Hordeum vulgare </em>L.) accessions over three consecutive cropping seasons in a semi-arid environment. Phenotypic analysis identified heading date and spike length as the two major traits contributing most to the total phenotypic variation under a semiarid climate. Hierarchical clustering grouped the 32 accessions into four groups. Although the effect of the interaction between genotype and environment was important for yield (48%), it had comparatively little influence on heading date (9.9%) and plant height (8.14%). Stability analysis identified the djebali accession, with the smallest coefficient of variability, as a stable genotype across the three assessed environments. Overall, based on the higher yield and small coefficient of variance, we selected 11 promising genotypes. In addition, varieties developed by the Tunisian breeding program were found to show high mean yield, stability across all environments, and greater adaptability. Accessions with superior adaptation and stability will be introduced into the national breeding program for further evaluation and characterization.

Senescence is an ordered degenerative process leading to death of individual cells, organs and organisms. The detection of a conditional lethal mutant (achloroplastic) of Hordeum vulgare has enabled us to investigate ultrastructural changes occurring in leaf tissue during foliar senescence.Examination of the tonoplast structure in six and 14 day-old mutant tissue revealed a progressive degeneration and disappearance of the membrane, apparently starting by day six in the vicinity of the mitochondria associated with the degenerating proplastid (Fig. 1.) where neither of the plastid membrane leaflets is evident (arrows, Fig. 1.). At this stage there was evidence that the mitochondrial membranes were undergoing retrogressive changes, coupled with disorganization of cristae (Fig. 2.). Proplastids (P) lack definitive prolamellar bodies. The cytoplasmic matrix is largely agranular, with few endoplasmic reticulum (ER) cisternae or polyribosomal aggregates. Interestingly, large numbers of actively-budding dictysomes, associated with pinocytotic vesicles, were observed in close proximity to the plasmalemma of mesophyll cells (Fig. 3.). By day 14 however, mesophyll cells showed almost complete breakdown of subcellular organelle structure (Fig. 4.), and further evidence for the breakdown of the tonoplast. The final stage of senescence is characterized by the solubilization of the cell wall due to expression and activity of polygalacturonase and/or cellulose. The presence of dictyosomes with associated pinocytotic vesicles formed from the mature face, in close proximity to both the plasmalemma and the cell wall, would appear to support the model proposed by Christopherson for the secretion of cellulase. This pathway of synthesis is typical for secretory glycoproteins.
