Did Plant Patents Create the American Rose?
Get PDFThe Plant Patent Act of 1930 was the first step towards creating property rights for biological innovation: it introduced patent rights for asexually-propagated plants. This paper uses data on plant patents and registrations of new varieties to examine whether the Act encouraged innovation. Nearly half of all plant patents between 1931 and 1970 were for roses. Large commercial nurseries, which began to build mass hybridization programs in the 1940s, accounted for most of these patents, suggesting that the new intellectual property rights may have helped to encourage the development of a commercial rose breeding industry. Data on registrations of newly-created roses, however, yield no evidence of an increase in innovation: less than 20 percent of new roses were patented, European breeders continued to create most new roses, and there was no increase in the number of new varieties per year after 1931.

Levels of physiological dormancy and methods for improving seed germination of four rose species
No full textLow seed germination is a major problem in commercial rose propagation and breeding and is species-dependent. The present work selected four rose species previously un-examined to explore effective methods for improving seed germination and the relevant dormancy mechanism and its levels in seven experiments. The results showed that both pulp and achenes from the four rose shrubs had chemical substances that significantly inhibited seed germination with the inhibitory effect was more pronounced in pulp extract than of achenes.

Vitamin C degradation of rose hips during drying and effects of drying medium on vitamin C degradation
No full textGültekin, Selahattin (Dogus Author)In this study, vitamin C degradation during drying of rose hips was investigated. The degradation of vitamin C was affected by time, temperature and content of moisture. Rate of vitamin C degradation during the drying of whole rose hips was satisfactorily described by a first-order kinetics, and the temperature dependency of the model was described by the Arrhenius relationship. The activation energy and the reaction rate constant were determined as a function of the moisture content. Drying experiments were also conducted on rose hips cut in pieces, and using air-CO2 mixtures. Cutting the rose hips before drying accelerated the drying process and increased the retention of vitamin C. The loss of vitamin C depended on the level of oxygen in the air-CO2 mixture used as a drying medium
Social Metadata for Libraries, Archives and Museums. Part 3: Recommendations and Readings
