weather, pests, and water. Most nutritional problems can be
quickly solved once you know the specific problem, but an
accurate diagnosis is difficult.
Foliar nutrient symptoms can be helpful, if you recognize
The elucidation of the structure of the red pigments of the black
raspberries. Monger variety, was achieved. The components of the
pigment of the berries were (a) cyanidin-3-glucoside, (b) cyanidin-3,
5-diglucoside, (c) cyanidin-3-diglucoside and (d) cyanidin-3-rhamnoglucosido-
5-glucoside. The elucidation was carried out after isolation,
purification, concentration and chromatographic separation of...

Red raspberry, Rubus idaeus L., is a valuable crop for the U.S. Pacific Northwest and clonal propagation is required to produce disease-free plants and for germplasm preservation. One challenge of red raspberry micropropagation is the wide variation in growth response among the cultivars. The studies described in this dissertation were...
