Daffodil Days

Distribution of Ditylenchus dipsaci in Daffodil Bulbs.

cots in the family Commeliaceae. The basic morphology of these plants appears to favor root-knot nematode development in aboveground plant parts. Leaves of both plants develop in the crown near the soil; they are large, 20-30 cm long, and densely arranged so that nematodes on younger leaves are protected from direct solar irradiation. The dense pubescent foliage, especially the convoluted young...

Catching the User - User Context through Live Logging in DAFFODIL

This demo will present the logging facilities to capture the user context within the Daffodil framework during a live search in computer science data sources. We propose to use the Daffodil system as an experimental framework for the evaluation and research of interactive IR. The system already provides a rich set of working services and available information sources. These services and sources...

Carbohydrate-binding specificity of the daffodil (Narcissus pseudonarcissus) and amaryllis (Hippeastrum hybr.) bulb lectins.

The carbohydrate binding specificity of the daffodil (Narcissus pseudonarcissus; NPA) and amaryllis (Hippeastrum hybr.; HHA) lectins, isolated from extracts of their bulbs by affinity chromatography on immobilized mannose, was studied by quantitative precipitation, sugar hapten inhibition, and affinity chromatography on the immobilized lectins. These lectins gave strong precipitation reactions ...
