Note: most peaks of moso bamboo occurred during April to June (big) and the second peak in October to December (small), and the lowest value occurred during the period between January and March. ^aThe percent of first peak value to total litterfall. ^bThe percent of second peak value to total litterfall. ^cThe percent of lowest value to total litterfall.
