Cattle Horn Shavings: A Possible Nitrogen Source for Apple Trees

IMapple: a source-sink developmental model for ‘Golden Delicious’ apple trees

Functional structural botanical tree models are one of the most difficult models in biology. We introduce IMapple, a model for ‘Golden Delicious’ apple (Malus × domestica) trees based on source-sink descriptions of plant resources. Our model uses precise geometrical representations with high quality polygonal meshes and geometric details. We introduce a novel simulation algorithm that provides ...

A Viroid Resembling Hop Stunt Viroid in Infected Apple Trees with Apple Scar Skin Disease in the Northeast of Iran

Abstract Background and Aims: Apple scar skin disease (ASSD) is one of the destructive diseases of pome fruits which is caused by ASSVd. Case presentation: We report molecular detection of ASSVd in symptomatic apples cv. Red Delicious with simultaneous presence of a new variant of HSVd from Khorasan Razavi province. Conclusion: This is the first report on the association of HSVd with...

Insects as a Nitrogen Source for Plants

Many plants have evolved adaptations in order to survive in low nitrogen environments. One of the best-known adaptations is that of plant symbiosis with nitrogen-fixing bacteria; this is the major route by which nitrogen is incorporated into plant biomass. A portion of this plant-associated nitrogen is then lost to insects through herbivory, and insects represent a nitrogen reservoir that is ge...
