Influence of sett fresh weight and depth of planting on performance of arracacha.
The Journal of Agriculture of the University of Puerto Rico, 2021 Quantitative information on the performance of arracacha is limited as to the influence of sett size and depth. Setts for propagation of this crop vary in size and fresh weight. Depth of planting appears to influence yield. The objectives of this study were to evaluate the influence of combinations of sett fresh weight and depth of planting on ...

Starch - Stärke, Volume 77, Issue 2, February 2025.The breadmaking potential of starches from Andean roots and tubers is compared to that of cassava, and related to their physicochemical, thermal, pasting properties, and their digestibility. The bread volume is negatively correlated with the WBC and starch damage. Oca and cassava starch shows the largest volumes. Oca bread crumb shows improved alveolar

Peroxidase activity in roots of arracacha affected by pH and temperature
Acta Scientiarum. Agronomy, 2011 In this paper, roots of arracacha (Arracacia xanthorrhyza Bancroft) were stored at 5oC to induce chilling injury symptoms and stress-related peroxidase activity. Later, peroxidase kinetic activity was determined in different pH and temperature conditions. For this, soluble crude extract was sequentially saturated with ammonium sulfate, obtaining a semi-

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Costa Rica
EFSA Journal, Volume 22, Issue 11, November 2024.Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica.
