Abstract:
Leafy vegetables could accumulate nitrate (NO3?) above limits safe for humans, hence it would be advisable to customarily determine their NO3? concentration. We wanted to develop a quick test to determine NO3? concentration in fresh tissue extracts and estimate the error of using this test to identify samples with NO3? concentrations above the World Health Organization (WHO) threshold. There was a positive linear relationship (P < 0.001) between NO3? concentrations determined by the quick test and by potentiometry in dry tissue extracts. Samples were classified as ?acceptable? or ?excessive? according to their potentiometric NO3? concentration, using a critical level of 75% (p) of the observed NO3? distribution. According to the Cate-Nelson model, the quick test identified as ?acceptable? from 5.6% to 15.4% of samples that were in the ?excessive? category. In spite of this error rate, the quick test use would improve consumers? protection, because no controls on vegetables NO3? concentration are available in Uruguay. |

ABSTRACT.
A method is described for obtaining interspecific hybrids between commercial lines of Lotus uliginosus Schkuhr and Lotus corniculatus L. Hybridization was possible between these species using embryo rescue. Two strategies were used to confirm 40 F1 hybrids, that is, flow cytometry and microsatellite simple sequence repeats (SSRs). The L. uliginosus and L. corniculatus parents have significantly different genome size (2.5 ± 0.02 and 2.22 ± 0.02 pg, respectively) and the offspring from the cross had intermediate values. Two SSR primers were polymorphic between the genotypes tested, TM1150 and EH380069. Maternal effect was detected in L. uliginosus genotypes, as determined by greater frequency of F1 hybrids. Recombinant traits were observed in the F1 hybrid progeny. Ninety F1 hybrids resulting from L. uliginosus × L. corniculatus crosses showed different levels of fertility in the polycross; <3% F1 plants produced more than 1000 seeds without embryo rescue while 10% of plants did not flower the first year. The F1 hybrid plants grown under greenhouse conditions exhibited shoot phenotypes similar to L. uliginosus (maternal) whereas F2 phenotypes were similar to L. corniculatus (paternal) in field trials. Rhizome presence was observed in 60% of F2 hybrid plants. The diameters of the root crowns of these plants, however, were similar to that of L. corniculatus.
