Leaf area meter and method for determination of banana leaf area in Brazil
2019-07-27 10:02:12
The leaves are important organs of plants, and photosynthesis and transpiration are all accomplished by the leaves. Therefore, the small area of ​​the leaves has a very important influence on the growth and development of the plants. There are many methods for determining the leaf area, but many methods are not suitable for the banana leaf area of ​​Brazil, mainly because of its large leaf area. Handheld leaf area meters are not available. The inability to use the leaf area meter makes it difficult to measure.
The statistical test results of actual and simulated values ​​of banana leaf area in Brazil show that the average absolute error and standard error of the simulated and measured values ​​of the leaf-volume product obtained from the product of the Brazilian banana leaf length, leaf width and length-width product during the vegetative growth period The correlation coefficient reached a very significant level. The average absolute error, standard error of error, and correlation coefficient between simulated and measured values ​​of leaf and accumulative product obtained by the length and length-breadth product of Brazilian bananas during the buds and budding stages were extremely significant. The level shows that the simulated value is in good agreement with the measured value.
The product of leaf and leaf length, leaf width and length and breadth of banana in Brazil during the entire growth period can be expressed by the same equation. However, this study is different. The reason may be that sampling is different. One strain was taken at random and five strains were modeled. , 5 tests, first, there are few samples; second is that the banana growth period is up to la, the study does not include the characteristics of the samples in each period; third, there is no differential treatment of fertilizer, because the different fertilizer water treatment of banana leaves is also in appearance Difference.
After the analysis of the application of leaf area meter, the data for this study included the entire growth period of two years of different fertilizer treatments, which was more representative; secondly, the study did not test the fitting coefficients in the equations, but this study was different, although The first, second, third and exponential modes of the model reached extremely significant levels. However, when the simulation coefficients were tested, only one function model coefficient reached a very significant level.
