Abstract: A new and distinct variety of rose plant is provided which bears highly attractive double relatively large blossoms which exhibit a colorful blend of yellow and rouge coloration. The new variety of the present invention resulted from the controlled crossing of an unnamed seed parent obtained by crossing the Meigold variety and the Peer Gynt variety with pollen from an unnamed parent obtained by crossing progeny of a cross between the Meialfi variety and the Meifan variety with the King's Ransom variety. The resulting variety possesses long arching canes as well as glossy deep green foliage. The new variety is particularly suited for growing in the U.S. landscape where climbing or pillar roses are customarily grown.

Abstract: A rose plant of the hybrid miniature class, having a unique petal coloration of soft cream edged with a delicate purple cultivated primarily for garden decoration.This invention relates to a hybrid miniature roseplant cv. Aroprawn. The plant is a dwarf bush outdoor seedling cultivated primarily for garden decoration.The seed parent was "Foxy Lady" (U.S. Plant Pat. No. 4,762) and the pollen parent was "Deep Purple" (U.S. Plant Pat. No. 4,672). The plant was hybridized by Jack E. Christensen in Ontario, Calif., by crossing "Foxy Lady" and "Deep Purple." The descriptive and comparative references to this plant and its bloom hereinafter will relate to plants of the same class grown in this region. This variety preserves its distinguishing characteristics through succeeding propagations, by cuttings and budding.This new variety is most readily distinguished from its seed parent, Foxy Lady (U.S. Plant Pat. No. 4,762), by the combination of the following characteristics.

Abstract: A new variety of rose plant of the Hybrid Tea class, being a half-hardy, outdoor, tall bush seedling, particularly adapted for garden decoration and which produces large pointed buds and large, slow-opening, long-lasting blooms on long, strong cutting stems. In contrast to other yellow roses, its clear yellow coloration lasts well throughout the life of the bloom.

Abstract: A new variety of rose plant of the hybrid Floribunda class, being a hardy, tall outdoor seedling of the bush type, grown mainly for garden decoration and which displays a unique multicoloration which is basically yellow, blushing to orange and finishing red. The flowers are produced in abundance, nearly continuously and are well distributed over the tall bush.

Abstract: A method and apparatus for detecting the presence of caries in human teeth using visible luminescence. A region to be examined is excited with a beam of monochromatic light. The intensity of the visible light emitted from the region is measured at two predetermined wavelengths, one where the intensity dependence of the spectra is about the same for caries and noncaries and the other where the relative intensity increases significantly in the presence of caries. A signal corresponding to the difference in the two intensities is obtained and then displayed. By first determining the magnitude of the difference signal at a nondecayed region, any increases in the magnitude as other regions are probed indicate the presence of caries. The invention is based on the discovery that the visible luminescence spectra for decayed and nondecayed regions of a human tooth are substantially different and that the differences are such that visible luminescence from teeth can be used to detect the presence of caries.
