Amino Acids in Different Plant Parts of Normal and Male-sterile Maize (Zea mays L.)
1971
Sarvella, Patricia | Grogan, C. O. | Stojanovic, B. J.
Amino acids were studied in the fertile and malesterile (Terns) versions of the single-cross maize (Zea mays L.) hybrid F44 ✕ F6 and the inbred parents. Samples were taken from leaves, stalks, tassels, ears, husks, and silks at various stages of plant development. Generally, leaves in the fertile versions were higher in amino-acid concentrations, while other vegetative organs showed no differences. However, in hybrid tassels after anthesis and in ears at all sampling dates, the male-sterile version had more amino acids than the normal version. Ears generally contained more total amino acids per unit weight than the other plant parts. The influence of both inbred parents was observed in the amino-acid content of the hybrid.
