Abstract

The detection of black mould rot infection (Aspergillus niger) in post-harvest sapota fruit was demonstrated by a X-ray imaging technique carried out six, seven and eight days post inoculation. It is suggested that X-ray imaging technology for detection of fungal infection may be useful as an imaging-based sapota sorting system.

Abstract

Pot culture experiments were used to evaluate the inoculation of peppermint plants (Mentha piperita) with Piriformospora indica. The effect of inoculation was observed in growth, yield, and composition of the essential oil of peppermint. Hydro distillation was used to extract oil from the dry matter of the shoot. Subsequently, GC/MS was used to determine their composition. The largest plant heights, dry shoot and root weights, and numbers of nodes were observed in pots that were inoculated with P. indica. The highest essential oil yield was obtained with P. indica-inoculated plants. GC and GC/MS revealed that P. indica enhanced menthol levels. T-test analysis showed that differences between treatment with P. indica inoculation and control were significant in root length, shoot dry weight, number of nodes and essential oil yield

Abstract

During August and September 2016, symptoms and signs of downy mildew were observed on stems and inflorescences of wild radish (Raphanus raphanistrum) plants in field plots in Cuapiaxtla, Tlaxcala, Mexico. Based on morphological characteristics, analysis of rDNA-ITS sequences, and pathogenicity tests on wild radish plants, the causal agent was identified as Hyaloperonospora brassicae. This is the first report of H. brassicae causing downy mildew on R. raphanistrum in Mexico.
