Leaf area duration (LAD) can be calculated by summing the leaf area at each measurement time point throughout the growing season. It is commonly calculated by using the trapezoidal rule to estimate the area under the curve of leaf area over time. This provides an integrated measure of the total leaf area produced by a plant over a specific period.
One common indicator of leaf area in pechay (Chinese cabbage) is the measurement of leaf length and width using a ruler or measuring tape. By multiplying these two measurements together, you can calculate the leaf area. Another method is using specialized tools like a leaf area meter, which provides a more accurate measurement of the total leaf area.
1 cm2= 100 mm2
The best method depends on the accuracy required of your measurements. If you require accurate and precise results, use a scientific instrument that's specially designed to measure the area of leaves. E.g. AM300 Leaf Area Meter
Calculating leaf surface area helps estimate the total surface available for transpiration. Transpiration is the process where water is evaporated from the surface of the leaf into the atmosphere, which is important for plant cooling and nutrient uptake. By knowing the leaf surface area, we can better understand the potential transpiration rate and overall water requirements of the plant.

Leaf surface area is important to measure in plant studies because it provides a quantitative measurement of the leaf's overall size and potential for photosynthesis. Understanding the surface area helps researchers analyze how efficiently plants can exchange gases with their environment, absorb light for photosynthesis, and regulate transpiration. Additionally, leaf surface area data can be used to compare different plant species, assess the impact of environmental factors, and evaluate the overall health and growth of plants.
length x width = area

There is no specific formula for finding the area of a leaf as the shape of leaves can vary widely. One common way to estimate the leaf area is by using a grid method, where the leaf is placed on a grid paper and the number of full squares covered by the leaf is counted. This count can then be used to calculate an approximate area. Alternatively, there are specialized instruments called leaf area meters that can measure the leaf area directly.
It is not possible to calculate the area given only the volume.
Here's what you do... take a graph paper.. the 1mm x 1mm graduated. trace the leaf on the graph paper. remove the leaf. then count the whole squares occupied by the leaf. write down the number. count the half 3/4th filled squares and write the number down. count the number of half filled squares and divide the number by two and write it down. leave out 1/4th filled squares. add the numbers you have written down. the number you get is the surface area of one side of leaf. doubling it will give you the surface area of the entire leaf in sq cm
