  • Abstract : Alternating temperatures were found to be required for the germination of seeds of Musa balbisiana. The temperature differentials optimal for germination in soil are dependent upon both the high and low temperatures, and range from 8-23 C. Germination is maximal when the seeds are held 6-12 hr at the high (27-35 C) and 12-18 hr at the low (12-18 C) temperatures. Some germination can be induced by short exposures to alternating temperatures followed by constant high temperatures, but continuous exposure to alternating temperatures is necessary for maximum germination. Excised embryos develop better at constant than at alternating temperatures, showing that the mechanisms affected by alternating temperatures reside elsewhere in the seed. Alternating temperatures are also required for germination of mechanically scarified seeds, although the temperature differentials are less than those necessary for intact seeds, indicating that the action of alternating temperatures is not on the permeability of the integuments.
