Hybridization rates between lettuce (Lactuca sativa) and its wild relative (L. serriola) under field conditions.
Hybridization and introgression between crops and wild relatives may have important evolutionary and ecological consequences such as gene swamping or increased invasiveness. In the present study, we investigated hybridization under field conditions between crop lettuce (Lactuca sativa) and its wild relative prickly lettuce (L. serriola), two cross-compatible, predominantly autogamous and insect...
متن کاملRecombination and spontaneous mutation at the major cluster of resistance genes in lettuce (Lactuca sativa).
Two sets of overlapping experiments were conducted to examine recombination and spontaneous mutation events within clusters of resistance genes in lettuce. Multiple generations were screened for recombinants using PCR-based markers flanking Dm3. The Dm3 region is not highly recombinagenic, exhibiting a recombination frequency 18-fold lower than the genome average. Recombinants were identified o...
متن کاملGrowth and Yield of Lettuce (Lactuca sativa L.) At Abakaliki Agro-Ecological Zone of Southeastern Nigeria
Studies were carried out in 2005 and 2006 raing seasons at four locations (Abakaliki, Ezzamgbo, Ikwo and Okposi) within the Abakaliki Agro-ecological zone of southeastern Nigeria, to determine their suitability for the production of lettuce. The measurements included weather elements, soil physico-chemical propertiesand crop growth and yield. The data collected were subjected to statistical ana...
متن کاملResponses of Lettuce (Lactuca sativa var. longifolia) Against to Different Time Exposure of Air Pollution of Exhaust Emissions
The experiment was conducted in factorial test based on a completely randomized design with three replications in greenhouse of Isfahan University of Technology of Iran. Lettuce seedlings were exposed separately to the exhaust emissions in three different exposure times (10, 20 and 30 days) and after the exposure time, their morphological, physiological and anatomical traits were measured and c...
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 ...
