Download or read book Evaluation of Chilling Temperatures Affecting Respiration and Net Photosynthetic Rates in Selected Inbred Maize (Zea Mays L.) Genotypes written by Jon Anthony Musgrave and published by . This book was released on 1999 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chilling air and soil temperatures greatly impact the germination ability of early planted crop species. Breeding maize (Zea mays L.) inbreds to be more tolerant of chilling conditions may improve seedling growth in stressful northern latitude seedbeds, decrease exposure to water stress, maximize available photon flux density (PFD), and create higher potential yields. An emphasis on cold-tolerance by maize breeders may have resulted in a substantial shift downward in the baseline temperature for maize germination and plant development. The focus of this research was to examine the respiration and net photosynthetic responses of eight inbred maize genotypes representing a range in field vigor while grown at or subjected to 6°, 8°, 10°, 12°, and 25°C.
