Wilt And Cold Resistance Of Self-Fertilized Lines Of Alfalfas, George L. Peltier, H. M. Tysdal
Wilt And Cold Resistance Of Self-Fertilized Lines Of Alfalfas, George L. Peltier, H. M. Tysdal
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The relative reactions to cold and wilt of self-fertilized lines of alfalfa through to the fifth generation are reported. Some of the reasons for undertaking a breeding program are given as well as methods used in the controlled cold and wilt determinations. Preliminary studies showed that reinoculating healthy individuals which had already resisted one wilt infection test served to eliminate additional plants, but the percentage healthy was much higher after the reinoculation than after the first inoculation. The foundation materials from which selections were made consisted of selected plants from a number of old Nebraska fields and a large collection …
The Effect Of A Controlled Nitrogen Supply With Different Temperatures And Photoperiods Upon The Development Of The Potato Plant, H. O. Werner
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The potato (Solanum tuberosum Linn.) is grown under a great variety of conditions with regard to temperature, length of day, intensity and character of light, texture, fertility, and moisture of soil, and atmospheric humidity. There is need for a better understanding concerning the internal response of the potato plant to these external conditions when they are applied, either singly or in combination with each other, and the resulting morphological response, especially with regard to the tuberization process. It has been the object of this investigation to determine the relation of the nitrogen supply to the processes of stolon and …
Cephalosporium Wilt And Die-Back Of The White Elm, R. W. Goss, Paul Raymond Frink
Cephalosporium Wilt And Die-Back Of The White Elm, R. W. Goss, Paul Raymond Frink
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A new disease of the white elm has been found to be common in eastern Nebraska. The causal organism has been isolated and its pathogenicity proved by inoculation. The fungus belongs to the genus Cephalosporium and is considered to be the same as that described by Curtis May of Ohio and found by him in specimens obtained in Iowa, Missouri, New York, and Washington, D.C. The morphology and cultural characters of the organism are described.
