Abstract
Photosynthetic characteristics of two important grasses of Indian desert have been studied. Pennisetum typhoides, an important cereal crop, known to have ‚Kranz’-type leaf anatomy and low CO2-compensation point, shows the C-4-dicarboxylic acid pathway for photosynthetic carbon reduction. Lasiurus sindicus, a promising forage grass, has also been shown to possess, for the first time, a typical ‚Kranz’-type leaf anatomy and a very similar CO2-fixation pattern like Pennisetum typhoides. It is remarkable that both species after short time exposure to 14CO2 show a high labelling not only in malate but also in alanine. This may be due to the activity of an aspartic acid decarboxylase.Keywords
