Alzheimer's disease (AD) is a neurodegenerative disorder associated with memory impairment and cognitive deficit. Most of the drugs currently available for the treatment of AD are acetylcholinesterase (AChE) inhibitors. Plants of the Amaryllidaceae family are known to synthesize alkaloids, which have shown AChE inhibitory activity. Habranthus tubispathus and H. jamesonii are two Amaryllidaceae ...

The purpose of this study was to investigate the response of physicochemical properties of gerbera (Gerbera Jamesonii L.) to silica nanoparticles (Nanoparticle-SiO2) and calcium chelate (Ca-Chelate) in nutrient solutions. A factorial experiment based on completely randomized design with two factors was conducted in four replicates. The first factor the concentration of Nanoparticle-SiO2 in nutr...

Cut gerbera (Gerbera jamesonii) flowers are sensitive to microbial contamination and have short vase life. The effect of salicylic acid, citric acid and ascorbic acid (50, 100 and 200 mg l-1) was evaluated on vase life of gerbera flowers. Changes in vase life, water absorption, and bacterial population in stem and vase solution, also biochemical characteristics such as protein concentration, li...

ten gerbera cultivars (‘labinel’, ‘lilla’, ‘alp’, ‘alberino’, ‘bonnie’, ‘avemaria’, ‘mammut’, ‘lexus’, ‘‘terramixa ’ & ‘sarolta’) were evaluated for their growth, yield and quality characteristics under protected conditions during 2011. among the cultivars studied, there were highly significant variations observed for growth, yield and quality parameters. longest stalk length (60.3 cm) was ...
