Magnetic Resonance Imaging (MRI) and light and scanning electron microscopy (SEM) were used to follow time-dependent morphological changes and changes in water status of tulip bulbs (Tulipa gesneriana L., cv. 'Apeldoorn') during bulb storage for 12 weeks at 20 degrees C (non-chilled) or 4 degrees C (chilled) and after planting. MR images reflecting the(More)
Plant mitochondrial genomes (mtDNAs) are large and undergo frequent recombination events. A common phenotype that emerges as a consequence of altered mtDNA structure is cytoplasmic-male sterility (CMS). The molecular basis for CMS remains unclear, but it seems logical that altered respiration activities would result in reduced pollen production. Analysis of(More)
Parameter sensitive MRI experiments were performed on tulip bulbs before and after storage at two different temperatures, 4 degrees C (chilled), and 20 degrees C (non-chilled). Quantitative measurements of the amount of magnetization transfer (MT) in the storage scales of the bulbs, were compared to the average values of the relaxation rates R(1) and R(2),(More)
