Short Video: How to Measure Growth Rate of Plants

Measuring plant growth is a very simple process and you can do it quickly. If you want to know the growth rate of indoor plants or if you need to calculate the growth rate of the laboratory specimen, you can do it easily. You need a little time to keep track of some easy supplies and factory growth rate.

3 The length and width of the mark. We choose randomly from 4 or 5 leaves. Fix the ruler from the bottom to the tip. Add the measured values ​​and divide by the measured number of measurements. (For example, if using 5-sheet measurement, divide by 5). This is the average leaf length of the day. Record on chart

5 Repeat the measurement every 2 to 3 days. Leaves can grow rapidly. Please check the leaf size every few days to see how they grow. For this purpose you can change the calculation formula of growth rate.

You can calculate leaf growth rate. By changing the growth rate formula like this, you can see how many leaves are growing every day. The formula for this growth rate is L1 = the number of the first leaf, L2 = the number of the second leaf, and T is the number of days between each leaf number.

The calculation formula of blade size is the same as the calculation formula of plant height. Variables are surface area, not height. The formula for the growth rate equation is S1 = first surface area measurement, S2 = second surface area measurement value, and T is equal to the number of days between each. [Four]

6 Create a growth template. After collecting several weeks of leaf traces, you can create templates using these shapes. Please take a piece of paper or cardboard. Make a minimum of tracking and create circles of the same size from the bottom of the paper. You can create up to six large circles. They should form concentric circles outside the first circle. Number each circle. One is the smallest and six are the largest. [Five]

In the future, we can easily measure leaves using this template. Grasp the leaf at the bottom of the paper and place it at the center of the smallest circle. Please mark the largest circle it will fill, do not cross, please record as leaf size

Petiole is a mobile-based precision agriculture recommendation system. It is a tool for measuring plant leaf area. It uses leaf area measurements to monitor dynamics of plant growth and to understand how plants respond to various factors (weather, growth promoters etc). It's like a smart tracker for plant growth

Measure the plants using a small ruler. The plants were measured once a day for 8 days as measured in millimeters from the top of the styrofoam to the top of the plant. After tracking the growth and effectiveness of the plant solution for 8 days, we summarized the information in order to compare the growth over the 8 days. Figure 4 "Thin Processing Growth Profile": These results are from elongation experiments of Brassica plants. It shows that plants treated with GA 3 are still expanding and controls appear to be expanding, but there are not as many plants as GA 3 treatments. Overall, control and GA 3 are much longer than Cycocel treated plants.
