Asexual reproduction

Definition - What does Asexual reproduction mean?

In botany, asexual reproduction refers to plant propagation without pollination. These plants do not need to disperse seeds or attract pollinators in order to produce a flower. Because female and male gametes do not merge during asexual reproduction, the offspring is genetically identical to the parent plants. These plants have also been shown to hold up well under stable environmental conditions since they carry identical genes from their parents.

MaximumYield explains Asexual reproduction

There are two main types of asexual plant reproduction: apomixis and vegetative reproduction. During vegetative asexual reproduction, the plant does not produce any spores or seeds. Plants that exhibit vegetative asexual reproduction include garlic, parsnips, daffodils and ginger. In apomixis reproduction, the plants give rise to fresh seeds without any fertilizer since a part of the ovary produces new seeds.

Plants can undergo artificial or natural asexual reproduction. In artificial reproduction, part of the stem is cut and placed in water or humid soil to produce a new root system. Another popular method of artificial asexual reproduction is grafting, whereby plants are attached to the root system of other plants in order to form a new one. In some cases, gardeners may propagate a plant by layering, whereby a portion of the plant’s stem is curved and buried with soil. This can generate a fresh root system which will give birth to a new plant.

While asexual reproduction has a myriad of benefits for both the parent plant and offspring, this method can sometimes lead to overcrowding. In some cases, the plants can become prone to certain botanical diseases due to a lack of genetic variation.
