Controlled pollination is a process of plant hybridization generally used in horticulture and genetic experiments. Traditionalplant breeding programmes require the involvement of the human hand to promote the reproductive process in plants. This can be achieved by controlled pollination. In this process, the pistillate flowers are wrapped in a transparent bag to safeguard them from undesired pollen grains. When these flowers are ready, they are brushed or dusted with the selected pollen to achieve the desired characteristics.

S In Artificial Hybridization

Hybridization proceeds in two steps:


We know hybridization is the method of selective breeding. Thus, anthers have to be removed from a bisexual flower before they release pollen grains. This step of removal of anther using forceps is termed as emasculation. In the case of unisexual flowers, this step is not necessary.


Bagging is the protection of emasculated flower from contamination by undesirable pollen grains. Here the flower is masked by a bag, still, the flower attains receptivity. In unisexual flowers, bagging is done before the flowers are open.

Emasculation and bagging ensure that the female flower is completely protected from contamination.

Once the flower attains stigma receptivity, the desired pollens are dusted on the stigma. This is resealed for further developments.

Hence, artificial hybridization ensures that the right type of pollen has been transferred to the stigma of the flower. In addition, the chance of fertilization is high. Through this approach, a variety of strains of crops can be developed and it improves the quality of crop with desirable characters.

Why Do You Need To Emasculate

Emasculation is commonly utilized by plant breeders to produce higher quality plant hybrids. It is by cross-pollinating two individuals specimens with two distinct desirable characteristics. Due to the cross-pollination, involving the pollen grains , and the egg cells that are both assumed to carry the needed qualities of the two individual samples, a superior variety is expected to be produced. This, hypothetically, would possess the aforementioned two distinct characteristics.

Artificial Hybridization In Plants

Artificial hybridization is the process in which only desired pollen grains are used for pollination and fertilization.

Pollination is the process of reproduction in plants in which plants transfer pollen grains from anther to stigma. Pollination can be of two types:

  • Cross-pollination
  • Self-pollination

For successful pollination to occur, pollen and stigma should be compatible. Incompatibility may lead to rejection of pollen grains. This situation is undesirable, especially in commercial crop production. Therefore, artificial hybridization was developed.

The Importance Of Tagging

This step helps to keep track of your plant breeding program either on a small or large scale. Using a thread tied to the flowers bag, information such as the dates of emasculation and pollination, and parent plants are normally written on the tags.

A simple yet fascinating process, emasculation allows us to manipulate and improve the plants in our environment, from the small hobbyist scale to the large commercial industry plant breeding. Emasculation proves to be an important methodology in botany.

Emasculation is a method to prevent plants from self-pollination. If you want to have your backyards full of quality plants, you can try the several methods mentioned above. Remember that you have to follow the right process, so you can have the expected results as planned.

What Is Emasculation In Plants

Emasculation may sound alienating and intricating for ordinary people because it is an academic and scientific connotation. But in general, it is a botanical process or technique that is simple and straightforward. So, what is emasculation in plants exactly?

Emasculation is a method of artificial hybridization where you remove the stamens of a flower without removing the female reproductive organ. In bisexual flowers, emasculation is essential to prevent self-pollination. In monoecious plants, male flowers are removed.

This is a full guide on everything you need to know about emasculation!

    Emasculation is the process of removal of anthers in bisexual flowers to prevent self-pollination. It is carried out in the following steps:

    It is a technique to prevent the fertilization of stigma from undesired pollen by covering the emasculated flower with butter paper. It is useful in a plant breeding programme because only desired pollen grains for pollination and protection of the stigma from contamination of undesired pollen.

    Pollination is a method where pollen grains are picked from an anther, which is the male part of a flower and transferred to the flowers female part called the stigma. All plants having flowers completely rely on the pollination method for reproduction. There are 2 types of pollination Self Pollination and Cross-Pollination.

    After dusting the pollen grains on the stigma of the emasculated flower, it is rebagged, and tag with relevant information such as date of emasculation, date of pollination, details of male and female parents, etc. are attached with plants. This is known as tagging.

  • What Is Emasculation

    Emasculation is a term commonly used in botany and biology, which refers to the practice of intervening with a bisexual plants pollination process. It is when the anthers-part of the plants male organ is removed to prevent self-pollination. With this, the female organ, called the stigma, must be left undamaged and will be subjected to cross-pollinating with another specimen with the desired characteristics.

    What Is Pollination

    When the desired male parent plant identified, its pollen grains are collected and transferred to the emasculated flower to crossbreed the two distinct origins. This step is usually performed in the morning as the plant undergoes an anthesis-the period of flowering, which starts when its flower buds open. The fertilized flower is usually re-bagged after this step.

    With this method, you will be removing the male gametes in your preferred flower to prevent it from pollinating itself. However, usually, flowers emerge in numbers within a single plant, giving the emasculated flower plenty of sources to fertilize their eggs. To combat this, breeders usually bag the emasculated inflorescence to isolate it from the other flowers, preventing unintended self-pollination.

    This technique also assures the breeder that no random cross-pollination would occur due to the transfer of pollen grains from nearby plants. Others consider deflowering the specimen, leaving only the emasculated plant.
