Several experiments were conducted in 1997 and 1998 at the Bergerac Tobacco Institute to investigate the effets of variety, nitrogen fertilization and after-curing storage modes on TSNA concentrations in air-cured tobaccos, Burley and dark types. The...

Somatic hybridization provides techniques for overcoming the interspecific incompatibility. This method offers new possibilities for transferring gene groups or families, chromosome parts or chromosomes and cytoplasmic genetic information. It induces...

Due to their genotype and curing mode, air-cured tobaccos usually have a higher content in tobacco-specific nitrosamines (TSNA) than Virginia flue-cured varieties. Two studies were conducted at the Bergerac Institute in 1996 and 1997 to measure the...

Somatic hybrid plants between N. tabacum (IVB ( bar )) and N. megalosiphon ( npt II) were recovered after polyethylene glycol (PEG) - mediated fusion and electrofusion. The hybrid calli were selected on plant regeneration medium on the basis of...

The hydroxybenzonitrile (oxynil) herbicides (bromoxynil and ioxynil) are a family of postemergence herbicides used for dicot-weed control in cereal, onion, and garlic crops. The resistance to these herbicides in monocots appears to be due to the...

Oxynils which include bromoxynil and ioxynil are a family of antidicot post-emergence herbicides used to control weed seedlings in cereal, onion and garlic crops. This selectivity appears to come from the detoxification of the herbicides by a...

The dark tobacco varieties grown in France, especially Burley, receiving a high nitrogen fertilization in order to get satisfactory yield, do not entirely reduce the absorbed nitrogen and accumulate it essentially in lower stalk positions. The first...
