Physiological and agronomic response of potato periderm russeting to measures for control of common scab

Creator:: Callihan, R. H. (Robert Harold), 1933-
Abstract:: Management factors used for studies on potato scab control were evaluated for their effect on tuber russeting and related biochemical and anatomical parameters during 1971 and 1972. Russet Burbank potatoes were irrigated in 1971 to maintain high available soil moisture (between 90% and field capacity) for 0, 3, 6 and...

Nutrient uptake by conifer seedlings as influenced by root CEC and competing species

Creator:: Schöne, Dieter Hans-Friedrich
Abstract:: The objectives of this study were to establish a suitable method for the measurement of the root cation-exchange capacity of conifer seedlings, and to examine possible influences of this root characteristic on nutrient absorption from a Bellpine soil under greenhouse conditions. The exchange sites of fresh, excised roots were saturated...
