Inheritance of Seed Color in Lactuca Sativa^
The mature fruit of lettuce is an achene or naked seed, the color of which is determined by the color of its pericarp. The pigments that give the seed its particular color seem to be localized in the pericarp tissues.^ The mode of inheritance of seed color is of immediate practical importance to those breeding lettuce for disease resistance, climatic adaptation, and desirable commercial charact...
متن کاملDepth Controlled Deuteron Irradiation of Lactuca Sativa
In a previous paper (2) the germination and subsequent growth of deuteron-irradiated lettuce seeds was described, with special emphasis on the influence of penetration depth. It was shown that depth of penetration is the predominant factor in eliciting the effects described, i.e., germination percentage and root length are affected at different depth levels. The general phenomena observed in ou...
متن کاملMutants of downy mildew resistance in Lactuca sativa (lettuce).
As part of our investigation of disease resistance in lettuce, we generated mutants that have lost resistance to Bremia lactucae, the casual fungus of downy mildew. Using a rapid and reliable screen, we identified 16 distinct mutants of Latuca sativa that have lost activity of one of four different downy mildew resistance genes (Dm). In all mutants, only a single Dm specificity was affected. Ge...
متن کاملToxic effects of copper-based nanoparticles or compounds to lettuce (Lactuca sativa) and alfalfa (Medicago sativa).
The increased production and use of nanoparticles (NPs) has generated concerns about their impact on living organisms. In this study, nCu, bulk Cu, nCuO, bulk CuO, Cu(OH)2 (CuPRO 2005, Kocide 3000), and CuCl2 were exposed for 15 days to 10 days-old hydroponically grown lettuce (Lactuca sativa) and alfalfa (Medicago sativa). Each compound was applied at 0, 5, 10, and 20 mg L(-1). At harvest, we ...
متن کاملPhytotoxicity effect of Silver nanoparticles on Oryza sativa
Phytotoxicity on Oryza sativa was studied by directly exposing it to silver nanoparticles solutions. Seedlings were allowed to grow at room temperature in Hoagland’s nutrient solutions prior to treatment. Particles were prepared in distilled water by Chemical reductions method. U.V-Vis spectra analysis confirms its formations at 400 nm wavelength. 12 days of phytotoxicity periods in 1000μg/ml c...
