If the female parent bears bisexual flowers, removal of anthers from the flower bud before the anther dehisces is referred to as emasculation.
Removal of anthers/stamens from the flower bud before the anther dehisces is referred to as emasculation.
Emasculation is the process of anther removal or stamen removal using forceps from a bisexual flower during the hybridization. This process involves the removal of stamens or anthers.
Emasculation. 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.
So, the correct answer is 'Emasculation'
IV.
The shoot apex tends to inhibit outgrowth of axillary buds, a phenomenon called apical dominance. Removal of the shoot tip leads to growth of these buds to produce lateral shoots.
Removal of apical (terminal) bud of a flowering plant (or pruning of a flowering plant) leads to. A. promotion of lateral branches. B. formation of adventitious roots on the cut side.
Emasculation means A removal of stamens before anthesis.
If the young stamens, (i.e., male unit) is removed artificially, the flower still has its pistil, (i.e., female unit) intact. Thus, cross pollination can occur.
Emasculation is the removal of stamens from female parent before they burst and shed their pollens.
So, the correct answer is 'Emasculation'
Emasculation is the process of removal of anthers before anther dehiscence i.e. before they are mature and release pollen grains.
Removing the small bean like anthers before they are covered in pollen will: 1.) prevent getting pollen everywhere which can stain both inside the flower and cloth.
The dehiscence of anther leads to the release of pollen grains. The anther ruptures at a specific site. If this site is on the outer side it is called extrorse dehiscence, if it is on the inner side it is introrse dehiscence and if it is towards other anthers it is called latrorse dehiscence.
It consists of the following stages: (1) Expansion of the epidermis and endothecium cells and deposition of U-shaped wall thickenings inside the latter. (2) Enzymatic opening of the septum between two locules. (3) Mechanical rupture of the tapetum.
The stomium is the region of the anther where dehiscence occurs.
The lack of pollen grains will make the plant male sterile.
A bisexual (or “perfect”) flower has both stamens and carpels, and a unisexual (or “imperfect”) flower either lacks stamens (and is called carpellate) or lacks carpels (and is called staminate).
So, the correct option is ' Emasculation'.
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.
The process of removing stamens or anthers from a flower before they dehisce or destroy the pollen grains without affecting the female reproductive organs. Bagging: To prevent pollination by unwanted pollen, the emasculated flower is enclosed in a bag. This is known as bagging.
Cuttings (Striking)
The most straightforward method of propagating plants is cutting or striking, in which a piece of parent plant containing at least one stem cell is removed and embedded in moist soil or other medium to form new roots. Some plants will root in water.
In zoology, abscission is the intentional shedding of a body part, such as the shedding of a claw, husk, or the autotomy of a tail to evade a predator. In mycology, it is the liberation of a fungal spore. In cell biology, abscission refers to the separation of two daughter cells at the completion of cytokinesis.
