Intraspecific mixtures may be a means of enhancing the genetic variability of modern crops while retaining the advantages of yield, quality, and stress tolerance of modern cultivars. Two- and three-way barley (Hordeum vulgare L.) mixtures of the cultivars Abee, Noble, Tukwa and Virden, were studied at Botha, Lacombe and Olds, Alberta, from 1992 to 1994. Treatments consisted of the four cultivars as monocrops and in 6 two-way and 3 three-way mixtures grown at a seeding rate of 250 seeds m−2. Tukwa as a monocrop had the highest rank and best stability for grain yield of all the treatments. Grain yields of the mixtures usually fell between the yields of the respective monocrops and were often better than the weighted mean yield of the monocrops indicating that many mixtures were more effective at using resources than the monocrops. Of the mixtures, Tukwa:Noble, Tukwa:Abee:Virden and Noble:Virden had the best rankings and stability for grain yield. Test weights, kernel weights, percent thins, lodging, disease incidence and protein content of the mixtures were intermediate to those of the monocrops. Mixtures containing the two-rowed cultivar Abee had higher test weight and protein content than mixtures composed of only six-rowed cultivars. Lodging and disease ratings were lower for the mixtures composed of only six-rowed cultivars than those with Abee. In these intraspecific barley mixtures, Virden was often the most competitive cultivar while Tukwa was the least. Competitive ability was not associated with yield potential, tillering, or row-type.

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.
