Differential responses of invasive Celastrus orbiculatus (Celastraceae) and native C. scandens to changes in light quality.
When plants are subjected to leaf canopy shade in forest understories or from neighboring plants, they not only experience reduced light quantity, but light quality in lowered red : far red light (R : FR). Growth and other developmental responses of plants in reduced R : FR can vary and are not consistent across species. We compared how an invasive liana, Celastrus orbiculatus, and its closely ...
متن کاملCytotoxic beta-dihydroagarofuran sesquiterpenoids from the fruits of Celastrus orbiculatus.
Assay-guided fractionation led to the isolation of nine beta-dihydroagarofuran sesquiterpenoids from the fruits of Celastrus orbiculatus. All isolated beta-dihydroagarofuran sesquiterpenoids were tested for their cytotoxic activity against human melanoma A375-S2 and human cervical carcinoma Hela cell lines. Among them, compounds 1-5 and 7 showed cytotoxic activity. Compound 3 exhibited promisin...
متن کاملCelastrus orbiculatus extract inhibits the migration and invasion of human glioblastoma cells in vitro
BACKGROUND Gliomas are highly aggressive tumors of the nervous system, and current treatments fail to improve patient survival. To identify substances that can be used as treatments for gliomas, we examined the effect of Celastrus orbiculatus extract (COE) on the invasion and migration of human glioblastoma U87 and U251 cells in vitro. METHODS The effects of COE on cell viability and adhesion...
متن کاملThe spatial legacy of introduction: Celastrus orbiculatus in the southern Appalachians, USA
1. A variety of abiotic, biotic, human and historic variables related to environmental suitability and propagule pressure determine the distribution of invasive plants in a landscape. Understanding the role of these variables for invasive species is challenging because environmental variables are often correlated, many invaders have broad ecological niches, and invasive distributions are often ...
متن کاملMaintenance of Pollen Germination Capacity of Vitis Vinifera L. (vitaceae)
Pollen germination of Vitis vinifera L., of the family Vitaceae was examined in fresh and stored pollen upto 48 weeks at different temperature i.e., refrigerator (+4C), freezer (-20C, -30C) and freeze drier (-60C). Pollen stored at low temperature showed better germination percentage as compared to pollen stored at +4C and fresh. Freeze dried pollen (-60C) showed the highest germination percent...
