Abstract: An apparatus for a disc tossing game is a free-standing target with a scoring sheet supported in a vertical orientation by a target support frame, which is perpendicularly attached to a base frame. The scoring sheet comprises a plurality of edge loops, within which the components of the target support frame are positioned in order to support the scoring sheet. The components of the target support frame and the base frame are elongated rods attached to each other at right angles by elbow fittings and tee fittings. The base frame comprises a number of stabilizing supports to prevent the target from falling over. The scoring sheet comprises a plurality of scoring holes, or slots, of various shapes, sizes, and positionings, through which players attempt to throw a sport disc in order to score points.

Abstract: A method for regeneration of sunflower plants via shoot induction from cotyledon explants prepared from non-germinated sunflower embryos is described. Several methods for preparing explants by dissection of mature and immature fully-formed embryos are provided. Explants are prepared to insure that substantially all of the induced shoots derive from single cotyledon cells. Appropriately prepared explants are cultured on a shoot induction medium containing a combination of BA and NAA. Induced shoots are rooted and the resulting plantlets are grown into mature sunflower plants. This regeneration method is efficient, rapid and employs a convenient explant source, sunflower seed. This regeneration method is particularly useful in combination with methods for introduction of foreign DNA into sunflower cells and tissue.
