Potentilla Fruticosa (rosaceae) as a Nectar Plant for Butterflies
Despite its wide distribution, little documentation exists to confirm that butterflies use the woody shrub Potentilla fruticosa (Linnaeus) (Rosaceae) as a nectar plant. During the summer of 2004, we observed 36 individual butterflies belonging to 10 species nectaring on P. fruticosa in the Jemez Mountains, New Mexico. Butterflies spent 56% of total observed nectaring time on P. fruticosa, where...
متن کاملProteomic analysis of Potentilla fruticosa L. leaves by iTRAQ reveals responses to heat stress
High temperature is an important environmental factor that affects plant growth and crop yield. Potentilla fruticosa L. has a developed root system and characteristics of resistance to several stresses (e.g., high temperature, cold, drought) that are shared by native shrubs in the north and west of China. To investigate thermotolerance mechanisms in P. fruticosa, 3-year-old plants were subjecte...
متن کاملQuality Evaluation of Potentilla fruticosa L. by High Performance Liquid Chromatography Fingerprinting Associated with Chemometric Methods
The present study was performed to assess the quality of Potentilla fruticosa L. sampled from distinct regions of China using high performance liquid chromatography (HPLC) fingerprinting coupled with a suite of chemometric methods. For this quantitative analysis, the main active phytochemical compositions and the antioxidant activity in P. fruticosa were also investigated. Considering the high ...
متن کاملSex determination methods in guppy (Poecilia reticulat)
Guppy, Poecilia reticulate, is a member of the Poecilidae family. This species is viviparous and one of the most popular ornamental fish in the world, whose phenotype is usually determined during the last ten days of pregnancy. However, most differentiation and development of secondary sexual traits are formed during adolescence, i.e. about 16 weeks after birth. These secondary characteristics ...
متن کاملInfluence of Environmental Factors on the Active Substance Production and Antioxidant Activity in Potentilla fruticosa L. and Its Quality Assessment
Environmental factors may influence types and contents of active substances. This study investigated the influence of environmental factors on the active substance contents and antioxidant activity of Potentilla fruticosa L. from different regions of China. Also, HPLC fingerprint similarity analysis (SA) coupled with hierarchical cluster analysis (HCA) and discriminant analysis (DA) were furthe...
