The article presents the results of research on optimizing methods intensification growing seed rootstocks based common quince VNIISPK breeding in a nursery. In course research, it has been found that highest yield with optimal economic and biological characteristics is provided by sowing germinated seeds late April. Seeds should be sown artificial beds according to scheme 0.5 cm x 20 cm, which...

than that used by American investigators. Exploration with other pure Beta emitters in colloidal form is in progress. Investigations in the intracavitary injections of liquid radioisotope such as sodium, bromine, and colloidal gold, or interstitial implantation of tantalum wire or gold grain for the treatment of carcinoma of the urinary bladder is reported by the Royal Marsden Hospital group of...

Hydrochorous dispersal through agricultural channels plays a role in structuring plant communities across landscapes. To date, research on seed retention vegetated areas has mainly focused vegetation types with simple architecture (often cylinders), which consequently do not represent real features. Here, we test the hypothesis that cover estimated at water surface best explains floating open c...

Seeds of the recalcitrant species lychee (Litchi chinénsis Sonn.) and longan (Dimocarpus longan Lour.) were stored near 100% relative humidity at 8 to 10C in air, 80% nitrous oxide (N2O) plus 20% oxygen, or 100% nitrous oxide. The combination of anesthetic and oxygen extended storage longevity of both species. Seeds stored in 100% N2O lost terminability at the same rate as those stored in air. ...

We present improved techniques for finding homologous regions in DNA and protein sequences. Our approach focuses on the core regions of a local pairwise alignment; we suggest new ways to characterize these regions that allow marked improvements in both specificity and sensitivity over existing techniques for sequence alignment. For any such characterization, which we call a vector seed, we give...
