The genus Rosa L. (Rosaceae) was recently treated floristically for North America, but range extensions and an additional taxon have been confirmed since then and are detailed here. These new reports document range extensions in the US and Canada of some native and introduced Rosa species, and new distributions and population data for several established Rosa hybrids (nothospecies). Some introd...

Nature of Work: ‘Santa Rosa’ magnolia, a selection of the native Magnolia virginiana L. (Sweet Bay magnolia) introduced by Woodlanders Nursery, Aiken, S.C. in 1979, is an upright, evergreen tree with an open growth habit.

Crisis due to global warming and its associated damaging consequences, including salinity, it is essential to develop plant resistance to salinity level. In this study, an experiment was conducted using different levels of salinity (0.05, 0.1, 0.15 and 0.2% sodium chloride) had on Rosa hybrida, as the most important cut flowers in the world. Results showed that by increasing of salinity, sodium...

the effects of sodium chloride (nacl) salinity (control; canal water with 0.4 ds m-1), 2.5 dsm-1, 5.0 ds m-1, 7.5 ds m-1 and 10.0 ds m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (rosa hybrida l.) cultivars viz. ‘kardinal’, ‘angelique’ and ‘gold medal’ were studied to achieve better management, quality product...
