| Background At present, species known as camote de cerro (Dioscorea spp.) are found only in the wilderness in Mexico, but their populations are extremely depleted because they are indiscriminately collected, it is urgent to evaluate the conservation status of these plants in order to design conservation genetics programs. In this study, genetic diversity parameters along with cluster analysis based on Jaccard's coefficient were estimated with the objective to assess the efficiency of Random Amplified Polymorphic DNA (RAPD), Inter Simple Sequence Repeat (ISSR), Amplified Fragment Length Polymorphism (AFLP) and Inverse Sequence Tagged Repeat (ISTR) molecular DNA markers in the Dioscorea genus. Results The polymorphic information contents were quite similar... |

| Abstract: The objective of this work was to evaluate the effects of infestation by Meloidogyne javanica on the vegetative development, nutritional characteristics, and antioxidant potential of beet (Beta vulgaris). Inoculation in beet seedlings was performed with 0, 1,000, 2,500, 5,000, and 10,000 eggs and with possible second-stage juveniles (J2) of nematodes. Plants were collected 60 days after inoculation for the evaluation of the nematological and vegetative parameters, the physicochemical composition, and the content and activity of antioxidant compounds. The population levels of M. javanica reduced the mass and diameter of the tuber, comparing inoculum levels of 0 and 10,000 eggs + J2 of nematodes. There was a significant difference for the number of... |

| In a greenhouse pot experiment with kohlrabi, variety Luna, we explored the joint effect of N (0.6 g N per pot = 6 kg of soil) and S in the soil (25-35-45 mg kg-1 of S) on yields, on N, S and NO3- content in tubers and leaves, and on alterations in the amino acids concentration in the tubers. S fertilisation had no effect on tuber yields. The ranges of N content in tubers and leaves were narrow (between 1.42-1.48 % N and 1.21-1.35 % N, respectively) and the effect of S fertilisation was insignificant. S concentration in the tubers ranged between 0.59 and 0.64 % S. S fertilisation had a more pronounced effect on the S concentration in leaf tissues where it increased from 0.50 to 0.58 or to 0.76 % S under the applied dose. The NO3- content was higher in... |
