The aim of the study was to determine influence habitat, cultivar and developmental growth stage on catalase activity in soil under two amaranth cultivars – Rawa (Amaranthus cruentus L.) Aztek hypochondriacus × Amaranthus hybridus L.). In a 3-year field experiment (2013–2015), amaranth’s plants were grown wide-row spacing good wheat complex south-eastern Poland (50°71'N, 23°04'E). included 4 va...

Tolerance to defoliation can be defined as the degree to which productivity is affected by photosynthetic area reduction. This trait was studied in grain amaranth (Amaranthus cruentus and A. hypochondriacus), which are considered to be a highly defoliation-tolerant species. The physiological and biochemical responses to increasing levels of mechanical leaf removal up to total defoliation were q...

Amaranth (Amaranthus sp.) is an underutilized pseudo-cereal with excellent nutritional and functional properties. The compositions, anti-nutritional mineral content of two species were evaluated by using standard procedures. Completely Randomized Design (CRD) was used for nutritional, treatments five replications. compositions Amaranthus cruentus hypochondriacus shown a significant difference (...
