A Glass Bead Semi-Hydroponic System For Intact Maize Root Exudate Analysis And Phenotyping, Martha G. Lopez-Guerrero, Peng Wang, Felicia Phares, Daniel P. Schachtman, Sophie Alvarez, Karin V. Van Dijk
Department of Agronomy and Horticulture: Faculty Publications
Background: Although there have been numerous studies describing plant growth systems for root exudate collection, a common limitation is that these systems require disruption of the plant root system to facilitate exudate collection. Here, we present a newly designed semi-hydroponic system that uses glass beads as solid support to simulate soil impedance, which combined with drip irrigation, facilitates growth of healthy maize plants, collection and analysis of root exudates, and phenotyping of the roots with minimal growth disturbance or root damage. Results: This system was used to collect root exudates from seven maize genotypes using water or 1 mM CaCl2, …
The Structure And Reproduction Of Corn, T. A. Kiesselbach
The Structure And Reproduction Of Corn, T. A. Kiesselbach
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The primary purpose of this paper is to summarize investigations concerning the structure and reproduction of the corn plant (Zea mays L.). Because of wide interest in the reproductive process in connection with breeding and genetic studies the floral development, fertilization, and embryology are especially stressed. The morphology and development of the vegetative organs is also included. The botanical relationship, origin, genetics and breeding of corn are briefly considered.
Freezing Injury Of Seed Corn, T. A. Kiesselbach, J. A. Ratcliff
Freezing Injury Of Seed Corn, T. A. Kiesselbach, J. A. Ratcliff
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The object of the investigations in this bulletin has been to determine the conditions under which freezing injury may occur to seed corn; to indicate, if possible, the vital changes in the embryo resulting in such injury; and to point out ways by which seed corn of strong vitality and satisfactory yielding capacity may be obtained.
