The results showed that the levels of arginine and arginase were the highest in cotyledons, which decreased slowly during plant development, followed by leaves and stems, with roots being the lowest.
The large amount of PAO could be found in the cytoplasm of parenchyma in cotyledon and in the cell membranes and intercellular spaces of cortical parenchyma in phyllogen.
Bamboo is also a monocarpic plant. But it can take more than 100 years for some bamboo species to flower, and even then, sometimes their roots push up new plants.
