Growth process of bamboo shoots

Detailed explanation of bamboo shoot growth process

1, prophase: it is the continuation of underground growth of bamboo shoots. Although the stem tip is outcropped, the stem is still in the soil, and the lateral expansion growth is obvious, the internode length is very small, the basal nodes take root one after another, and the height growth is very slow, and the average daily growth is only 1 ~ 2 cm.

2. Ascending period: the elongation and growth of internodes in the underground part of bamboo shoots basically stopped and became the stem base of bamboo poles in the future. A large number of bamboo roots germinate and the root system gradually forms. The internode growth activity of bamboo shoots moves from underground to aboveground, and the growth speed is gradually accelerated, and the growth amount is correspondingly increased, generally reaching 10 ~ 20cm per day.

3. Peak period: It is the fastest growing period of bamboo shoots. While the bamboo roots continue to elongate and begin to develop lateral roots, the height growth of bamboo shoots is rapid and stable, rising in a straight line. Growth peak 1 day and night length can reach about1m. Bamboo shoots began to fall off at the base, and the upper branches began to spread, and the high growth rate changed from fast to slow. Bamboo shoots gradually transition to the young bamboo stage. In addition to the tip covered with bamboo shoots, under the action of light, chlorophyll is produced between the middle and lower nodes, which turns into green "bamboo green" for photosynthesis, providing some nutrients for the growth of bamboo shoot seedlings.

4. Late stage: Young bamboo shoots bend, branches extend rapidly, and the high growth rate decreases obviously, and finally stops. After all the bamboo shoots are peeled off and the branches grow, all the bamboo leaves spread out to form a new bamboo.
