Abstract

Length and dry-matter content of root and shoot, relative rate of photosynthesis and activities of ribulose 1,5-diphosphate carboxylase and phosphoenolpyruvate carboxylase were studied in seedlings of two hybrids and their parents. Heterosis for these characters was fairly high during the early stages of growth but declined with time, resulting in almost no heterotic advantage. Growth and photosynthesis, when split into components, appeared to show Mendelian dominance in the F1 hybrids. Complementation of these processes in the F1 and interaction among them eventually made the F1s markedly superior to their parents.
