Emasculation is done during artificial hybridisation or artificial pollination between two selected parent plants showing desirable characteristics. It helps to prevent self pollination in a bisexual or monoecious plant.
Removal of stamens or anthers or killing the pollen of a flower without the female reproductive organ is known as emasculation. In bisexual flowers, emasculation is essential to prevent of self-pollination. In monoecious plants, male flowers are removed. (castor, coconut) or male inflorescence is removed (maize).
Emasculation is done in the early morning by removing the anthers of the disc florets in 2 to 3 whorls with forceps and the other florets in the head are removed. About 9-10 am the pollens from desired male parent are collected and dusted on the emasculated head. This process is continued for 2 to 3 days.
Explanation: Emasculation is a process of removal of anther or stamen or the pollen of bisexual flowers without affecting female reproductive parts which are known as pistils. It is done to prevent self-pollination in bisexual flowers.
Solution: Emasculation is the process of removing the male portion of a bisexual flower, the anther. The male reproductive component (stamens) of a flower, usually a bisexual flower, is removed during emasculation. This is done in order to make the flower entirely female.
Hint: Emasculation is the process of removal of male reproductive organ of a flower. It is mainly done in bisexual or monoecious plants.
It is done before the anthers are mature. If in a condition the female parent bears bisexual flowers, then elimination of anthers from the flower bud before the anther dehisces by means of a pair of forceps (a large instrument with broad blades) is necessary. And this step is known as emasculation.
There is a high wastage of pollen grains that need to be produced to ensure fertilization occurs. There are high chances that the good qualities may get eliminated and unwanted characteristics may get added due to recombination of the genes.
Emasculation is followed by bagging the flower and then the desired pollen grains are introduced on the stigma for hybridisation. It is done in the flower which is selected as the female parent because after emasculation only the female reproductive parts of the flower remain in it.
Bagging of the emasculated flowers during hybridisation experiments is essential to prevent contamination of its stigma by undesired pollen grains.
Stigma receptivity is at the peak during morning hours. Emasculation is to be done in the evening hours before the anthers are dehisce and stigma is likely to become fully receptive. Care must be taken not to injure the gynoecium.
Short-term consequences of emasculation include bleeding and infection. Historically, death was also a potential complication, although the prevalence is disputed.
When a man feels emasculated, he will start displaying some fewer masculine traits, including a lack of confidence, a more passive personality, and a tendency to let you make all the decisions. You may not have realized it, but if your man is exhibiting any of these signs, then it could be that he feels emasculated.
Emasculation is the process of removal of anthers before anther dehiscence i.e. before they are mature and release pollen grains.
Emasculation – Emasculation is the process of artificial hybridization where the pollen and anthers of the flower are separated to prevent self-pollination. Bagging – Bagging involves covering the emasculated flower with a bag to prevent pollinating agents from reaching it.
Example Sentences
He plays the role of a meek husband who has been emasculated by his domineering wife. Critics charged that this change would emasculate the law.
D. It is done in flowers of plants selected as a male plant. Hint: Emasculation technique is performed by only plant breeders. It is a process of removal of anthers from a bisexual flower such that self-pollination is not favored.
Emasculation is removal of anther from a bisexual or hermaphroditic flower to prevent self pollination. If the flower is unisexual, or has either one of the gametes, self pollination is not possible within the flower. Hence, emasculation is not required.
Emasculation is a method in which anthers are removed from the flowers to prevent self-pollination.
The anthesis, emasculation and actual crossing are preferably done early in the morning or late afternoon because blooming occurs early in morning & stigma receptivity is high & it is also done during evening because most of the anther dehisce during evening.
Theory. Emasculation is the process of artificial hybridization in which the stamens from the female flowers are removed from bisexual flowers in order to prevent self-fertilization. This process is carried out long before the anthers mature.
Terminology. Effeminate comes from Latin effeminātus, from the factitive prefix ex- (from ex 'out') and femina 'woman'; it means 'made feminine, emasculated, weakened'.
To weaken. The second sense of emasculate is essentially to weaken someone, to enfeeble them. This is not restricted to men, and so no “feminine” version is needed. Weakening a woman and weakening a man are the same thing.
A plant breeding technique in which the stigma of a flower is covered with bags is known as the bagging technique. In the bagging technique, the anthers of a bisexual flower are removed and the flower is wrapped with paper bags or butter paper.
