Three genetically different dwarf cultivars of spring wheat were
evaluated as potential sources of short stature to use in a wheat improvement
program. The study involved a five parent diallel cross
which included a semidwarf, a standard height and three dwarf cultivars.
The genetic sources of dwarfism included a Norma...
Alkylation of propylene oxide with 2-lithiofuran gave alcohol I,
which was smoothly converted to acetylfuran II. hydrogenation of II
over rhodium on charcoal followed by Jones' oxidation afforded ketone
III. Further transformation into IV was accomplished via a Wittig
reaction followed by saponification with methanolic sodium hydroxide.
Hydroboration of the...
This investigation examined the community structure of two intertidal sedimentary environments on the Oregon coast in terms of species composition and vertical distribution.
A coring device was used to obtain samples from two levels above MLLW in each beach on four occasions. Of the 54 taxa found, 46.2% were crustaceans,...
