A taxonomic study of the genus Ophionectria Saccardo is presented.
The genus is described and the only remaining species, the type species,
Ophionectria trichospora, is described and figured. Ophionectria
trichospora is compared with Nectria haematococca to define relationships
between the two genera.
All other species formerly placed in Ophionectria are...
Phyllopane microorganisms on the leaf surfaces of bean
(Phaseolus vulgaris L. ), hop (Humulus lupulus L. 'Fuggle-H'),
mint (Mentha piperita L. 'Mitcham') and tomato (Lycopersicon
esculentum Mill. ) has been observed by cultural methods. A leaf
impression method was used to examine both actively growing and
inactive propagules present on...
The objective of this investigation was to develop an acceptable
aspartame sweetened orange sherbet which might offer significant
caloric reduction and cost advantages, and hence be applicable to

A control sherbet, with a preference level equal to a
commercially available orange sherbet was used as the reference.
An...
