Abstract: The present study was undertaken to (a) evaluate the use of the shrunken-2 mutants instead of the standard sweet corn through a transplant routine management, (b) determine the mechanism involved in post transplant sweet maize root restriction and (c) show the effect of container cell volume on vegetative growth which let explain previous field results. Sweet maize mutants hybrids Canner (sugary) and Butter Sweet (shrunken-2) were sown by direct seeded at 1, 2, or 3 L pots or in plastic plug trays (70 cells tray-1) for transplant. The results suggested that acceptance of Butter Sweet shrunken-2 sweet corn mutant would not be able to limited by germination and field emergence. By the other hand, the decrease in shoot growth observed in transplanted maize seedlings would be related to a previously container size root restriction which would not be an extreme case of mechanical impedance. A mechanism associated to changes in the synthesis or translocation of cytokinin from the root apex has been hypothesized.
