The anatomies of 44 galls are discussed with special attention given to the development, longevity, and tannin content of the nutritive tissues. Within the main section of the thesis, representative galls from the major cecidogenetic groups, with the exception of bacterial and Australian scale
galls, are studied. These include galls...
Crown gall infected and healthy Kalanchoe pinnata (Lam.)
Persoon plants were analyzed for soluble amino acids. Specifically
the amino acids in young leaf, mature leaf, stem, root, and gall
tissues were quantitatively measured. The plants were inoculated
with the bacterium, Agrobacterium tumefaciens (Smith and Townsend)
Conn., on one side of...
Few discoveries of any importance have been the result of a moment's happy coincidence; rather have they been the fruit of many hours of tedious thought and experiment. This is especially true in the realm of organic chemistry. Here, where progress is made only by the most painstaking experimentation, extensive...
Anyone with an interest in plants or insects, anyone who cares for a lawn, grows a crop, or enjoys an outdoor walk sooner or later will notice galls. The purpose of this booklet is to provide brief answers to some of the common questions that people ask about galls and...
Evaluation of meta-sedimentary bedrock as a source of stored water available
to plants in a mediterranean climate is presented based on: root length distribution
(RLD), root morphology, rock water holding capacity and seasonal pattern of water
depletion. Studies were performed in southwestern Oregon under young stands of
whiteleaf manzanita, ponderosa...
