When cut the plant will release hormones, auxin, gibberellins largely, which cause and regulate plant growth. Depending on the stage of growth and how and where the cutting/topping was done, the plant will push out two, three or four new main leaders. The plant will not grow as tall as it would have had it not been trimmed. The growth will be spread out between the two, three or four new main leaders. The plant will also push out new growth below where the bud was trimmed making it a bushier plant on top of being a shorter plant. If someone wants four main leaders their best chance to get them is to grow a plant until it's sixth true node begins to grow and then cut the plant back to about a half inch above the second node. More times than not it will result in four or three new main leaders, though two is possible too, just less likely when topping is done that way.

What is apical growth?
It is when growth occurs at the tips of roots and shoots of a plant
What will happen if apical meristem is damaged or cut?
if the apical meristem is damaged or cut the plant will not show growth.
What hormone is responsible for apical dominance?
Apical dominance is a concentration of growth at the tip of a plant shoot, where a terminal bud partially inhibits axillary bud growth by using hormones.
What tissue is responsible for a plant's unceasing growth?
The tissue that is responsible for a plant's unceasing growth is the meristematic tissue. It is also known as growing tip and is located in the buds. It contains undifferentiated cells that promote growth.
What is the function of apical meristem?
Apical meristem is found at the tip of the root and shoot and is made of cells that divide at a rapid pace. The apical meristem helps the plant to grow up above the soil and down into the ground. This growth is called primary growth.
Which part of a plant produces continuous growth at the tips of the stems and roots?
The apical meristem
What is the site of primary growth for plants?
one answer: cell growth, which is caused by photosynthesis.
Where does does plant growth occur?
Primary growth in plants occurs at the apical meristem.
Does plant growth occur at the lateral buds?
Lateral buds develop generally when apical dominance is terminated
When plant cells divide why does growth only continue at the tip of the plant?
Because the apical parts in plants have meristematic cells without differentiation into permanent cells. Also apical buds having active cell division have lesser quantity of growth promoting hormones like IAA and cytokinins etc.
What is growth that makes stems grow taller or roots grow longer called?
The first part of a plant to grow is the root. The mesocotyle of the seed can be differentiated into epicotyle and hypocotyle.
Which plant hormone produced in apical meristems inhibits the growth of axillary buds?
The class of hormones called "Auxins" have this affect on plants.
