Effect of some plant extracts against damping-off disease of some winter vegetable was studied in the net house. Seed treatment with neem leaf, garlic clove, allamonda leaf, ginger rhizome, kalijira seed, bel leaf, turmeric rhizome, katamehedi leaf and onion bulb were evaluated against damping-off, seed germination and growth characters of tomato, eggplant and chilli seedlings. All the treatmen...

In the present study, the Allium cepa chromosome assay was employed as a preliminary test to investigate the mutagenic and antimutagenic potential of three plants, namely Clinacanthus nutans, Adhatoda vasica, and Carica papaya, used by traditional practitioners in Malaysia against a direct acting mutagen-Methyl Methanesulphonate (MMS). Onions were planted in various treatment groups: plant extr...

Two mild and two pungent onion (Allium cepa L.) selections (hereafter referred to as cultitypes), W420B, W424B, MSU8155B, and Exhibition, were grown at two locations in two states (Wisconsin and Oregon) during 1994 and 1995. Onion bulbs were harvested, stored at 4 °C and sampled for antiplatelet activity, pungency, and soluble solids 10 days after harvest and every 40 days during a 210-day post...

Onion (Allium cepa) consumption has been remarked in folk medicine which has not been noted to be administered so far as an adjunct to conventional doxorubicin-based chemotherapy in breast cancer patients. To our knowledge, this is the first study aimed to investigate the effects of consuming fresh yellow onions on hepatic enzymes and cancer specific antigens compared with a low-onion containin...

Human rights workers, activists, and spies, among other groups and even ordinary citizens, may desire the ability to communicate via the Internet without revealing who they are or what they're doing. This can be accomplished through the user of anonymous network protocols, whose goals are to provide anonymity to the network user. Onion routing is a distributed P2P application that allows two pe...

Garlic and onion alliin lyases, although from closely related species, have many differences. The two enzymes differ in their K(m) values, pH optima, and isoelectric points. There is a major difference in their molecular weight and subunit structure. The garlic holoenzyme has a molecular weight of 85,000 and consists of two subunits of molecular weight 42,000. The onion enzyme has a holoenzyme ...

Onion intake might reduce the risk of colorectal cancer, according to epidemiology. However, Femia showed in 2003 that diets with a 20% onion intake increase carcinogenesis in rats. We speculated this dose was too high. Prevention of initiation was thus tested in 60 rats given a 5% dried onion diet or AIN76 diet, and initiated 12 days later with azoxymethane (AOM, 1x20 mg/kg i.p.), 2-amino-3-me...

Sour skin is a common bacterial disease that can affect most onion varieties all over the world (Burkholder 1950; Sotokawa and Takikawa 2004). Because sour skin bacteria have an uncanny ability to survive in moist environments, it is one of the major threats to the sweet onion industry with up to 50% losses in some fields or storage rooms (Howard F. Schwartz 2008). Sour skin bacteria can enter ...

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is an important pest on onion and cabbage. Two reproductive modes--arrhenotoky and thelytoky--are found in this species and co-occur in the field. We compared life table traits between arrhenotokous and thelytokous T. tabaci on cabbage and onion. Experiments were conducted in cages to determine which reproductive mode is more compe...
