Abstract
Cytoplasms of two maize (Zea mays L.) inbreds, GA 199 and GT 112 with a nuclear genotype in common, were used to determine if the maternal cytoplasm of an inbred line can influence nutrient absorption.
Significant cytoplasmic differences occurred in the absorption of NO3, NH4 and K during the 0–10 and 11–20 day seedling growth periods. Maternal cytoplasm had no significant effect on the total absorption of the other nutrients evaluated. Root and shoot dry‐weights of plants with GT 112 cytoplasm were 13 and 18%, respectively, below those of plants with GA 199 cytoplasm.
