Root Rots of Wheat, Oats, Rye, Barley
The root rots of wheat, oats, barley, and rye are among the least conspicuous diseases of cereals, but they are among the most destructive. They are caused by many species of fungi, which are widespread and live on or in seed, soil, and dead plant refuse. They attack a large number of hosts and thrive under a wide range of conditions. To the many types of root rots in cereal crops many names ha...
متن کاملCarboxylic Acids in Wheat, Rye and Barley
Organic acids from w heat ( Triticum aestivum), rye (Secale cereale), and barley (Hordeum vulgare, var. “G erbel” and “ Igri” ) were analysed by gas c h ro m a to g ra p h y -m ass spectrom etry. Two carboxylic acid fractions were obtained by chrom atography on Sephadex LH 20: frac tion A contained m ainly aliphatic acids, fraction B contained m ainly arom atic acids. The identified com pounds...
متن کاملTranscriptionally active heterochromatin in rye B chromosomes.
B chromosomes (Bs) are dispensable components of the genomes of numerous species. Thus far, there is a lack of evidence for any transcripts of Bs in plants, with the exception of some rDNA sequences. Here, we show that the Giemsa banding-positive heterochromatic subterminal domain of rye (Secale cereale) Bs undergoes decondensation during interphase. Contrary to the heterochromatic regions of A...
متن کاملComposition of guttation fluid from rye, wheat, and barley seedlings.
This work was undertaken to determine the kinds and amount of substances that would account for the previously demonstrated differential growth of Claviceps purpurea on guttation fluids from Rosen rye, Genesee wheat, and Traill barley seedlings. Chromatographic methods were used for determining amino acids and sugars, spot tests and spectrometric methods for inorganic materials, and microbiolog...
متن کاملDNA Comparisons among Barley, Oats, Rye, and Wheat.
F all groups of plants, none can match the cereal grains in importance to O m a n . Their origins in cultivation have been traced back some 9,000 years to the beginnings of agriculture ( HELBAEK 1960). Extensive cytogenetic studies have been undertaken with this group of plants from which their taxonomic and supposed evolutionary relationships may be deduced (BELL 1965; RILEY 1965). Some of the...
