Effect of storage in overcoming seed dormancy of Annona coriacea Mart. seeds.
The aim of this study was to evaluate the effect of pre-treatments on overcoming dormancy of A. coriacea seeds. Seeds were processed and stored in polyethylene bags at temperatures of at -18°C (42% RH), 5°C (34% RH), 15°C (60% RH) and 25°C (34% RH), during 0, 30, 60, 90, 120 and 150 days. After storage, seeds were immersed in 350 mg.L-1 gibberellic acid for 144 hours. Sowing was carried out in ...
متن کاملAqueous Extract of Annona macroprophyllata: A Potential α-Glucosidase Inhibitor
Annona genus contains plants used in folk medicine for the treatment of diabetes. In the present study, an aqueous extract prepared from Annona macroprophyllata (Annonaceae, also known as A. diversifolia) leaves was evaluated on both the activity of yeast α -glucosidase (an in vitro assay) and sucrose tolerance in Wistar rats. The results have shown that the aqueous extract from A. macroprophyl...
متن کاملPhytochemical Analysis of Annona Squamosa Seed Extracts
Annona squamosa seed extracts were studied for their phytochemical constituents, total phenolics and flavonoid contents. For this purpose different tests of petroleum ether, chloroform, ethyl acetate and methanol extracts of Annona squamosa were extracted and concentrated. The preliminary phytochemical screenings of Annona squamosa for its phytochemical constituents were performed using general...
متن کاملHistochemical Detection of Acetogenins and Storage Molecules in the Endosperm of Annona Macroprophyllata Donn Sm. Seeds
Acetogenins (ACGs) are bioactive compounds with cytotoxic properties in different cell lines. They are antitumoural, antiparasitic, antimalarial, insecticidal, antimicrobial, antifungal and antibacterial. These secondary metabolites function in plant defence and are found in specific organelles and specific cells, thereby preventing toxicity to the plant itself and permitting site-specific defe...
متن کاملMethods for overcoming seed dormancy in jimsonweed (Datura stramonium L.)
This study aimed to examine dormancy-breaking of jimsonweed seeds. Seeds were collected from Hamedan. They were subjected to different treatments: (a) concentrated sulfuric acid for 1, 1.5, and 2 min; (b) hot water at 80°C and 90°C for 5 and 10 min; (c) mechanical scarification with sandpaper; (d) light exposure for 10, 20, and 30 days; and (e) fluctuating temperature (5–15°C). The highest germ...
