A leaf spot diseases of English holly caused by an undescribed species of Sclerophoma

Creator:: Brown, William M., 1935-
Abstract:: English holly culture in Oregon has been threatened by the development of red leaf spots which prevent sale of cut holly. Chemical, mechanical and insect injury and boron deficiency have been shown in the past to cause different types of red leaf spotting, but the cause of holly scab, a...

Cytokinin production by Agrobacterium tumefaciens

Creator:: Kaiss-Chapman, Richard Wilkinson
Abstract:: Certain plant-associated prokaryotes such as Corynebacteriurn fascians and Agrobacterium tumefaciens are known to produce substantial levels of cytokinins. In view of the fragmentary and presumptive evidence available on the quantitative and qualitative levels of cytokinins produced by A. tumefaciens, it was decided to conduct a study of the cytokinins produced...

Cytokinin biosynthesis in crown gall tumors

Creator:: Akiyoshi, Donna E.
Abstract:: Using combined HPLC-RIA, cytokinin levels in a series of tobacco crown gall tumors, having altered morphologies as a result of transposon mutagenesis were examined. Average trans-ribosylzeatin levels in the shoot-producing tumors (tms mutants) and root-producing tumors (tmr mutants) were 1400 pmol/gm and 0.97 pmol/gm, respectively. Cytokinin/auxin ratios were highest in...

Structural Results and Approximation Algorithms in Minor-free Graphs

Creator:: Le, Hung V.
Abstract:: Planarity has been successfully exploited to design faster and more accurate approximation algorithms for many graph optimization problems. The celebrated theorem of Kuratowski completely characterizes planar graphs as those excluding K_5 and K_{3,3} as minors. Kuratowski's theorem allows one to generalize planar graphs to H-minor-free graphs: those that exclude a...

The influence of climate change and restoration on stream temperature

Creator:: Diabat, Mousa
Abstract:: Water temperature is an essential property of a stream. Temperature regulates physical and biochemical processes in aquatic habitats. Various factors related to climatic conditions, landscape characteristics, and channel structure directly influence stream temperature. Numerous studies indicate that increased average air temperature during the past century has led to stream warming...
