The objective of this work was to study the effects of different concentrations of NaCl on the emergence and vigor of Petunia x hybrida hort. Vilm E. ex., Torenia fournieri Lind and Tagetes patula L. seedlings. The experimental design was entirely randomized with five treatments (five concentrations of NaCl: zero, 25, 50, 75 and 100 mM) and four replications of 50 seeds, for each species. The seeds were germinated in germitest paper at the alternating temperature of 20-30°C. Emergence (%) and Emergence Rate (ER) were performed daily until 14 days. Salt stress caused negative effects on the emergence and vigor on seedlings of these three ornamentals species.

The objective of this work was to perform an analysis of the composition, diversity and quality of the tree flora (trees and palms) existing in Rui Barbosa Square, São José do Rio Preto, São Paulo State. This square is considered the main place for its location, history and use, and is located in the central region, next to the Cathedral. The arboreal individuals present in the square were counted, identified and evaluated the height and circumference of the trunk at the height of the chest; were determined phytosociological descriptors, Shannon-Weaver index and observed qualitative aspects (stem-glass balance, general status of the specimen, phytosanity and presence of association with other organisms: insects, lichens, epiphytes or parasites). The fl...

Among the vegetation elements, 362 individuals (trees and shrubs) were identified, covering 80 species, 69 genera and 41 families. The Shannon-Weaver biodiversity index of the area was 3.48. Many plants (50%) are not of Asian origin, mischaracterizing the garden. Some elements such as the pagoda, a stone lamp, Mount Fuji and the bridges to the island in the center of one of the lakes were according with the philosophy of a Japanese garden; however, other aspects like commemorative plates, trash containers and concrete benches were uncharacteristic. The survey conducted to know the visitor profile and value for local respondents concluded that most visitors have high school education (42%), are women (52%) or are between 41 and 60 years old (44%). Most (88%) are unaware of the principles that guide the Japanese garden style. The style of the garden is not fully characteristic and showed maintenance problems.
