The volatile leaf essential compositions of all 17 serrate leaf margin species of Juniperus (sect. Sabina) of the western hemisphere are reported and compared: J. angosturana, J. ashei, J. californica, J. coahuilensis, J. comitana, J. deppeana, J. durangensis, J. flaccida, J. gamboana, J. jaliscana, J. monosperma, J. monticola, J. osteosperma, J. occidentalis, J. pinchotii, J. saltillensis, and...

The inoculation of a Debaryomyces hansenii strain in dry fermented sausages with reduced fat and salt contents was evaluated in terms of chemical, microbial and consumer acceptability. The implantation of the inoculated yeast strain was confirmed by RAPDs of M13 minisatellite. A reduction of 17e20% salt and 10e16% fat content was achieved. These reductions affected the sausage quality by produc...

Genetic relationships were studied among four taxa in the genus Chaenomeles using isozyme analysis. The band patterns obtained with six polymorphic isozyme systems provided 108 reliable markers, which were scored as unordered multistate traits. A cluster analysis as well as a multidimensional scaling analysis grouped the taxa in agreement with previously published results obtained with RAPD (ra...
