BACKGROUND AND AIMS Some frost-tolerant herbaceous plants droop and wilt during frost events and recover turgor and posture on thawing. It has long been known that when plant tissues freeze, extracellular ice forms. Distributions of ice and water in frost-frozen and recovered petioles of Trifolium repens and Escholschzia californica were visualized. METHODS Petioles of intact plants were cryo...
LINDOW, S. E., D. C. ARNY, and C. D. UPPER. 1978. Erwinia herbicola: a bacterial ice nucleus active in increasing frost injury to corn. Phytopathology 68: 523-527. Cell suspensions of an isolate of Erwinia herbicola from a herbicola, frost damage was not significantly different from corn leaf were active in ice nucleation at -2.3 C and below, that to controls. The amount of damage increased gre...
The current US corn grading system accounts for the portion of damaged kernels, measured by timeconsuming and inaccurate visual inspection. Near infrared spectroscopy (NIRS), a non-destructive and fast analytical method, was tested as a tool for discriminating corn kernels with heat and frost damage. Four classification algorithms were utilized: Partial least squares discriminant analysis (PLS-...
