Abstract
Supersweet corn (Zea mays L. var. rugosa.) which contain endosperm mutant shrunken -2 exhibits low seed vigor and poor field emergence especially when soil temperature is 10-15 °C. Based on their emergence in the field at low temperature, they can be divided into two groups as tolerant and sensitive cultivars. Two cultivars 'Illini Gold' (Tolerant) and 'Honey 'n' Pearl' (Sensitive) were studied to see any anatomical differences, holes and cracks in the pericarp and air pockets between pericarp and aleurone layer. Significant differences were found in the thickness of pericarp. 'Illini Gold' cultivar has thicker pericarp and thin walled aleurone layer cells. 'Honey 'n' Pearl' has thinner pericarp and less lignified cells of aleurone layer suggesting that sensitive nature of 'Honey 'n' Pearl' is due to its thinner pericarp which provides less resistant to incomig and outgoing water and the nutrients necessary for growth. Air pockets between pericarp and aleurone layer of both the cultivars were prominent.
