Why does bamboo die after it blossoms?

Bamboo is a relatively common plant. Because bamboo propagates asexually with underground stems, it can only blossom when it is dying or when it is ravaged by water, drought, or insect pests, which is easy to cause people to associate with barren years, disasters and hunger. therefore, some people in China regard it as a sign of fleeing famine and troubled times, so let's take a look at why bamboo died after flowering.

Does bamboo really blossom?

Bamboo blossoms. Bamboo does not blossom and bear fruit every year like ordinary flowering plants, so some people mistakenly think that bamboo does not blossom. In fact, bamboo is a flowering plant, and it has to blossom and bear fruit after a certain period of time. Bamboo will die after flowering because it does not have enough nutrients to continue to grow. White floc usually appears during flowering. There are white filaments and a kind of small particles the size of rice grains in the flower spike, which is called bamboo rice in folk. Bamboo flowering has a great impact on ecology, such as giant pandas will die because of lack of food.

The flowering cycle of bamboo

The flowering cycle length varies with different bamboo species, which is not only affected by heredity, but also related to the natural environment. Some bamboos take more than ten years or decades to bloom, such as Phyllostachys pubescens and Banna sweet bamboos take about 30 years to bloom, Phyllostachys pubescens and Phyllostachys pubescens need 32 years to bloom, some species of Phyllostachys take more than 80 years to bloom, and some even take as long as a hundred years to bloom. For example, osmanthus takes 120 years to blossom. Of course, there are a few exceptions, such as Qunrui bamboo and linear bamboo, which blossom about once a year, while Tang bamboo and filial piety bamboo bloom irregularly.

Why does bamboo die after it blossoms?

Why does the bamboo die after it blossoms? This is a question that people have been puzzled for a long time, and scientists hold different views on it. Some scientists believe that when bamboo grows to a certain age, it is bound to age. In order to reproduce, it will blossom and bear fruit before the end of life. Bamboo flowering consumes the nutrients stored in bamboo whips and poles, and most species, such as Phyllostachys pubescens and pear bamboos, die above ground and underground after flowering. However, a small number of bamboo species, such as Phyllostachys pubescens, Phyllostachys pubescens, Phyllostachys pubescens and so on, die in the aboveground part after flowering, while the buds in the underground part can still be rejuvenated, and some individual bamboo species, such as Phyllostachys pubescens and Phyllostachys pubescens, remain green after flowering, and the underground parts do not die. However, the flower branches should be cut off as soon as possible to reduce nutrition consumption, so as to ensure the normal growth of bamboo forest.
