the subject handled in this study is the determination of antioxidant activities of extracts obtained from the urginea maritima (l.) baker plant’s leaves and tubers. extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. the antioxidant activity of the extracts was determined using β-karotene-linoleic acid system. moreover, the free radical scavenging ...

an investigation was carried out to reveal the changes in the concentration of soluble carbohydrates under tuber dormancy in food yam (dioscorea esculenta) tubers and in an economically important spice cum medicinal plant turmeric (curcuma longa) rhizomes under storage. harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28 ? 2?c t...

The infection of intestinal flukes is endemic in a big area of Saharsa District and is a great public health problem. It has affected mostly the poor people and has devitalised such a population leading to a great economic loss.

given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. this study was conducted during 2012-2013 at the research center of agricultural university of tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. a...

Three Ca sources and two application schedules were compared for their effectiveness for increasing tissue Ca concentrations in 170 to 284 g field-grown tubers of ‘Atlantic’ potato (Solanum tuberosum L.). Additional observations were made of internal physiological defects. Paired measures of tissue (periderm and nonperiderm) Ca concentration and internal quality (± hollow heart, ± internal brow...

We report two cases of solitary cortical tubers not associated with tuberous sclerosis and having an appearance simulating neoplasm in two patients presenting with seizures. CT showed solitary, hyperdense frontal lobe lesions in both patients. MR revealed a lesion hyperintense on both T1- and T2-weighted images in one patient and a heterogeneous mass with a target appearance in the other. Histo...

Tuberborne diseases of potato, such as Potato virus Y and Potato leafroll virus, present significant problems for potato seed growers and producers alike. An emerging disease of potato, called “Zebra Chip” or “Zebra Complex” (ZC), has recently appeared in the United States and elsewhere and is causing significant losses to individual growers and processors. First identified in northeastern Mexi...

Metham sodium applied in October through center pivot irrigation systems was evaluated for control of Meloidogyne hapla at 374, 468, and 701 liters/ha and for control of M. chitwoodi at 468 liters/ha on potato. Metham sodium at the high rates effectively controlled M. hapla. No females were detected in the tubers at the high rates of nematicide application, whereas a mean of 19 and 69% of the t...
