Specific Gravity of Corn Stem Sections1

D. L. Thompson2

Specific gravity (dry), i.e., dry weight/green volume, of 50-mm stem sections of corn (Zea mays L.) was significantly correlated with stalk lodging, stalk rot rating, crushing strength, rind thickness, and puncture rating. Dry weight of sections was similarly correlated. Two other types of specific gravity (green and absolute) were generally not as well correlated. Specific gravity and dry weight evaluations were obtained approximately 1 month after pollination, were determined independntly of lodging stress, and were useful measures of stalk strength.

Key Words: Lodging • Stalk breakage • Stem strength • Dry weight • Density
