True potato (Solanum tuberosum) seed (TPS) is used for preservation of variable genetic lines of wild and cultivated potatoes (Hawkes et al., 2000) and for propagation of food crops in some developing countries. TPS has advantages over seed potato tubers in storage and transportation and favors lower virus infection levels...
Samples of Russet Burbank and Kennebec seed potatoes
used by Oregon growers were grown in replicated plots at
Klamath Falls, Prineville and Corvallis. Observations
were made of total yield, yield of U.S. No. 1 tubers and
number of stems produced per plot.
Total yields of the Russet Burbank variety were...
Producers in the Willamette Valley of Oregon are interested in growing canola as a rotational crop in grass seed and cereal rotations. Many other Brassicaceae seed crops also are produced within the valley. Concerns of seed persistence and volunteer contamination of Brassicaceae seed crops prompted the investigation of seed persistence...
Rubus seed characteristics; seed coat morphology, anatomy, germination requirements and dormancy were studied in order to define protocols for breaking seed dormancy. Morphological analysis of the seed coat (testa) using scanning electron microscopy (SEM) included 56 seed accessions of 10 subgenera preserved in the collections of the US Department of...
Elite inbred sunflower (Helianthus annuus L.) lines were found to have short-lived embryo and seed covering dormancies. Seed dormancy of wild sunflowers (H. annuus, H. argophyllus and H. exilis) was found to be controlled primarily by the seed covering (seed coat and pericarp) and embryo dormancy was short-lived (four to...
A study was conducted to determine the influence of DMSO
(dimethyl sulfoxide) on suberization and wound periderm formation
in cut potato tuber tissue, and to determine the effectiveness of
DMSO as a potato seedpiece treatment for prevention of seedpiece
decay in the field. The influences of tuber storage conditions,
varieties,...
