Abstract

The reaction of field-grown micropropagated bananas, Musa cv. Williams (AAA, Cavendish subgroup) and cv. Goldfinger (AAAB, FHIA-01), to subtropical race 4 Fusarium oxysporum f. sp. cubense (Foc) was compared with the reaction of plants grown from conventional planting material (sections of the rhizome, termed bits). Leaf gas exchange of plants was determined, and growth and dry matter accumulation were measured. Comparisons were made among these parameters from shortly after planting, throughout winter, and into spring when a high percentage of the plants started to show external symptoms of fusarium wilt. Micropropagated bananas were significantly more susceptible to race 4 Foc than plants derived from bits. This was irrespective of planting times, cultivars used, or whether the bits had first been established in containers in the glasshouse (as for micropropagated plants) or been planted directly in the field. This greater susceptibility does not appear to be a consequence of differences in maximum photoassimilation rates, greater photoassimilate demand, or lack of carbohydrate reserves once plants became established.
