Bamboo leaves From the perspective of plant morphology, bamboo has two forms of leaves, namely stem leaves and nutrient leaves. Stem leaves are born on bamboo stalks, also known as stalks, bamboo stalks, bamboo shoots and so on.
The leaves of the bamboo leaves are leafy and the leaves are alternate. The leaves are divided into three parts: leaf sheath, petiole and leaf. The leaf sheath wraps between the twigs, and the inner side of the joint between the sheath and the leaf has a protruding tongue called the lobes. The ear-like protrusions on both sides are called the ear, and the edge of the ear often has shoulder hair. Some bamboo species have neither a leaf ear nor a shoulder hair. Some bamboo leaves have only shoulder hair and no ears.
Bamboo leaves usually have a joint between the leaves and the sheath, and the leaves fall off the joint when they are old. The leaves are generally lanceolate, with a apex acuminate and a base contracted. The size of the leaves varies greatly among the bamboo species. The maximum length can reach 40-50 cm, such as hemp bamboo and dragon bamboo, and the smaller one is 2-3 cm long, such as phoenix bamboo. The leaf regeneration is periodic, usually once a year, and the bamboo is once every 2 years. The buds from the nodes of the deciduous twigs develop into new leafy branches instead of deciduous twigs. Many bamboo species can judge the age of bamboo plants by the number of twigs left by the bamboo leaves when they are renewed.
