What is the difference between auxanometer and Crescograph?
A crescograph is a device that is used to measure the rate of growth in plants. An auxanometer, also known as an arc-indicator, is a device that is used to measure the growth of plants.
What is auxanometer function?
An auxanometer (Gr. auxain= “to grow” + metron= “measure”) is an apparatus for measuring increase of growth in plants. In case of an arc-auxanometer (see picture), there is a thin cord fixed to the plant apex on one end and a dead-weight on the other with a pointer indicating against an arc scale.
Who invented auxanometer?
Koningsberger
An auxanometer also known as an arc-indicator is defined as an apparatus which is used for measuring the growth in plants. The meaning of auxanometer is auxin stands for to grow and metron stands for the measure. This apparatus was invented by Koningsberger.
How will you obtain plant growth by auxanometer?
Step 1: Take ordinary scale. Step 2: Measure ground stem up to the growing point of the plant. Step 3: Use Indian ink and mark at regular intervals to measure the length of root, stem, and girth of the trunk.
What is a crescograph used for?
A crescograph is a device for measuring the growth in plants. It was invented in the early 20th century by Sir Jagadish Chandra Bose. The Bose crescograph uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant (or its roots).
Which of the following can be measured by Auxanometer?
Option A- Growth in length: Auxanometer is an instrument which is used to measure the growth rate of a plant in terms of length with the help of an arc indicator. Sensitive auxanometer also records growth of even a few micrometers.
