Banana is one of the oldest cultivated fruit trees in the world, which originated in Asia, Malaysia and southwest China. Nowadays, banana cultivation originated from wild bananas with long stems and sharp leaves. Both kinds of wild bananas can produce seeds and grow normally. However, banana with pointed leaves has small fruit and good taste, but its ability to resist harsh environment is poor and it is not easy to grow. However, long-stemmed bananas have strong adaptability, but the taste is not good; Moreover, the seeds of both bananas are hard and inconvenient to eat.
People let these two kinds of bananas cross, and under the conditions of artificial cultivation, irrigation and fertilization, wild bananas are slowly cultivated into new varieties, which changes the hard characteristics of seeds. In fact, now we will see rows of brown spots in banana pulp, that is, degraded seeds. Degraded A seeds can't grow bananas, so people use banana buds and underground stems to cultivate new banana trees through asexual reproduction.
