“…In relation to nitrogen fertilization, the response of radicchio varieties differs, as high and low nitrogen demanding varieties were previously reported [47]. The average values (n=3) with different lowercase letters in a row are significantly different (P<0.001; differences between the fertilizers), and those with different uppercase letters in a column are significantly different (P<0.001; differences between the varieties).…”

“…Theoretically, the surface area of the branched root system can be wider than that of the tap root system with a smooth straight shape. Cassan et al (2008) suggested that the nitrogen use efficiency of witloof chicory during the root production could be genotype dependent. The authors also pointed out that further breeding effort may enlarge the genetic variability of the species for the nitrogen metabolism and it can expand the geographical adoptability of this crop.…”

“…Our former work on the inbred lines (NS1, Alg, NR1 and NR2) (Richard-Molard et al, 1999) as well as the work on the commercial hybrid lines (Cassan et al, 2008) suggested a negative relation between nitrogen reserves content in the tuberized root at the beginning of the forcing process and nitrogen reserves mobilization. In the present work, the hypothesis of a genetic association of these traits is supported by the coincidence of the QTLs of these traits on LGs 1 and 3 under N− and on LG 6 under both N conditions.…”

“…In our previous studies, carried out by Richard-Molard et al (1999) on four chicory lines (NR1, NR2, NS1 and Alg) and Cassan et al (2008) on a set of 13 F1 hybrids, we have shown that nitrogen supply during the vegetative phase influenced dry weight partitioning between the shoot and the tuberized root in a genotype-independent manner. The shoot/root dry weight ratio increased with the increase in nitrate supply as a result of an increase in the shoot dry weight with, however, almost no effect on the tuberized root dry weight, as previously observed by Améziane et al (1995).…”
