Oxygen uptake characteristics of the roots of three Rumex species were compared, and related to kinetics of the respiratory system and to root anatomy. The observed differences could not be explained by differences in fundamental characteristics of the oxygen uptake system: with all three species, cytochromemediated respiration contributed 70% and cyanideinsensitive (alternative) respiration 30...

Little is known how the deep root systems of perennial crops contribute to deeper and better resource use when intercropped with annuals in arable fields. Therefore, we aimed at measuring capacity deep-rooted perennials, alfalfa ( Medicago sativa L.) curly dock Rumex crispus access nutrients located under neighboring 1.0 2.5 m soil depth. Alfalfa were able tracer sources 15 N Cs) placed a dista...

Computer vision can lead toward more sustainable agricultural production by enabling robotic precision agriculture. Vision-equipped robots are being deployed in the fields to take care of crops and control weeds. However, publicly available datasets containing both image data as well from navigational robot sensors scarce. Our real-world dataset RumexWeeds targets detection grassland weeds: Rum...

Antiproliferative and antioxidant activities and mycosporine-like amino acid (MAA) profiles of methanol extracts from edible wild-harvested (Chondrus crispus, Mastocarpus stellatus, Palmaria palmata) and cultivated (C. crispus) marine red macroalgae were studied herein. Palythine, asterina-330, shinorine, palythinol, porphyra-334 and usujirene MAAs were identified in the macroalgal extracts by ...
