The correlation coefficient between the leaf length and leaf width and the leaf area was calculated, and if the correlation coefficient was measured at a significant or extremely significant level, the regression equation was calculated again, and the leaf area measured by the checker method was used as a control for the t test. Verify the reliability of the regression equations that are obtained, and then follow the regression equation to create a correspondence table with leaf area at a certain distance.
The results showed that the difference between leaf traits (leaf length, leaf width) and leaf area of ​​Citrus reticulata leaves was not significant. However, from the scatter plots of leaf length, leaf width, and leaf area, it can be seen that the actual observed values ​​of leaf width and leaf area are closer to the regression line, which suggests that the leaf area estimated by the width of the leaves of the mandarins is appropriate. In order to test the reliability of the leaf area as estimated by the leaf width regression equation, the paired data t test using the leaf area measured by the grid method was compared to show that t<0105, indicating that the leaves were calculated using the leaf width regression equation. There is no significant difference in the leaf area measured by the area method and the grid method. Therefore, it is accurate and reliable to use the leaf width regression equation to determine the leaf area.
When the leaf area analyzer method was used to determine the leaf area of ​​the mandarin, this method was rapid, simple and can be measured in large quantities without damaging the plants. It is an ideal method for determination. In the determination of other plant leaves, the application of this instrument is also worth recommending and is an important instrument for modern plant research.
Leaf area analyzer plays an important role in the determination of citrus leaf area
The non-leaf organ is one of the most important organs in the growth process of citrus. The size of its leaf area has an important influence on the yield of citrus. However, there is a certain degree of objectivity in the determination of citrus leaf area. Because the details of Lugan branch are short, and the apricot is also small, and the number is large, there are many inconveniences in the determination process. If the determination is performed in vitro, Affects plant growth and development. Therefore, in the determination of the leaf area of ​​the dried mandarin orange, a leaf area meter that does not damage the leaf can be used for the measurement analysis.
