Hybridization of a diploid wheat with Aegilops speltoides (a closely allied species of grass), followed by doubling of the chromosome complement, produced tetraploid wheats.
The development of bread wheat (T. aestivum), a hexaploid wheat, involved the hybridization of a tetraploid wheat with A. tauschii, a closely allied diploid species of grass, followed by chromosome doubling to 42.
This began to change recently, and Grass followed the trend with his 2002 novel, "Crabwalk," about the Wilhelm Gustloff, a Nazi cruise ship that was sunk by Soviet torpedoes in 1945, sending almost nine thousand German refugees, many of them children, to the bottom of the frozen sea.
Due to the difference in plant morphology and effective surface cover, runoff delay, total discharge retention and peak-flow reduction with shrubs (seabuckthorn) were more effective than those with secondary natural grass, followed by biological crust and bare soil.
In the first experiment, 5 multiparous Finnish Ayrshire cows (229 d in milk) were used to compare the effects of feeding diets based on grass followed by hay during 2 consecutive 14-d periods separated by a 5-d transition during which extensively wilted grass was fed.
In the first experiment, 5 multiparous Finnish Ayrshire cows (229 d in milk) were used to compare a diet based on fresh grass followed by hay during 2 consecutive 14-d periods, separated by a 5-d transition during which extensively wilted grass was fed.
The three crop rotations were, respectively, permanent grassland, 3 years with grass followed by 1 year with beets (Beta vulgaris L). and 2 years with maize (Zea mays L ., and 3 years grassland followed by 1 year with beets and 4 years with maize.
Numbers are presented as weight percentages of DM in the raw grass, followed by standard deviations (a,b,c,d).
Part of the Public Theater and Theater for a New Audience's celebration of the four-decade collaboration between Mr. Shawn and the director André Gregory, "Grasses" follows this summer's superb revival of "The Designated Mourner," a political fable of moral cowardice that made anyone with a conscience squirm.
Plantains and coarse grasses followed these tough pioneers.
