Abstract
Description
Technical Field
[0001] The invention relates to the technical field of plant diversity analysis, and in particular to a method for analyzing physical traits of flowering cabbage plant diversity. Background Art
[0002] Chinese cabbage is a famous specialty vegetable in South China. It has many varieties and close genetic relationships. Therefore, accurate identification of plant diversity is very important for germplasm resource evaluation. The traditional method is to directly use plant traits such as plant height, spread, number of leaves, leaf weight, main stem length, main stem thickness, main stem weight, single plant weight and number of branches for simple direct comparison. It is also often combined with statistical software such as Excel, DPS, SPSS for systematic correlation analysis, principal component analysis and cluster analysis. For example, eight traits such as plant height were used to evaluate the plant diversity of 27 Chinese cabbage. The results showed that the main stem thickness, main stem weight, leaf weight and single plant weight all had large coefficients of variation, and the correlation between some traits reached a significant level, showing rich plant diversity. Most of the information of Chinese cabbage can be represented by two principal components, the main stem factor and the leaf factor. Excellent Chinese cabbage is characterized by increased height, thickness and weight of the main stem, and reduced number of leaves and weight. Cluster analysis divided the 27 Chinese cabbage into three categories. The values of eight traits of the 18 Chinese cabbage in the first category were low, the values of the seven Chinese cabbage in the second category were higher than those of the first category, and the main stem thickness and weight were the largest. The main stem thickness and weight of the two Chinese cabbage in the third category were lower than those of the second category, and the values of the other traits were the highest. Traditional methods can accurately identify the plant diversity of germplasm resources. The more traits used for plant evaluation, the larger the amount of data, and the more reliable the results, but the analysis results are difficult to achieve the purpose of being simple, batch, direct and intuitive.
[0003] Therefore, in order to address the problem that traditional analysis is difficult to achieve simplicity, batch, directness and intuition, a physical trait analysis method for Chinese cabbage plant diversity can be designed, that is, multiple complex botanical traits are converted into three simple physical traits for statistics, the botanical trait comparison is reduced to the physical trait comparison, and the botanical trait cluster analysis is converted into the physical trait cluster analysis, so as to achieve simplicity, batch, directness, intuition, strong logic and high credibility of the analysis results. Summary of the invention

When the ρ value of a certain sample is greater than or equal to the median of all the samples measured, it means that the luxuriance of the plant is large.
[0013] Preferably, when conducting a physical cluster analysis of Chinese flowering cabbage plant diversity, all varieties are first sorted and classified according to the main stalk volume ratio, and the main stalk volume development degree is evaluated according to the median. Secondly, they are sorted and classified according to the stalk-leaf weight ratio, and the main stalk weight development degree is evaluated according to the median. Finally, they are sorted and classified according to density, and the luxuriant growth degree of the plants is evaluated according to the median.
[0014] Preferably, when investigating plant traits, the main stalk height The height from the root of the main stalk to the top of the main stalk when viewed from the front; the diameter of the main stalk The diameter of the thickest part of the main stem.
[0015] The whole plant is simulated as a cylinder, and the plant volume is calculated according to the cylinder volume formula: plant volume = π*square of the spread radius*plant height. =π* * , calculate the main stalk volume according to the cylinder volume formula, the main stalk volume = π * the square of the main stalk radius * the main stalk height, =π* * .
[0016] Preferably, when investigating plant traits, plant height It is the height from the ground to the top of the plant when viewed from the side; It is the longest distance and the widest distance when looking down at the leaves of the plant.
[0017] As a preferred method, when measuring the trait value using a ruler, microcaliper and balance, the main stem diameter The unit is millimeter, the other volume measurement units are centimeters, and the weight measurement unit is grams.
[0018] Example 1 1. Plant traits survey: The properties were measured using a ruler, microcaliper and balance. The unit of measurement for volume was centimetres, except for the diameter of the main stem, which was millimetres. The unit of measurement for weight was grams.
[0019] The nine characteristics of Chinese cabbage plants investigated were: plant height ( )、Development( )、Number of leaves( )、Ye Chong( )、Main stalk height( )、Main stalk diameter( )、Number of lateral branches( )、Main stalk weight( ) and plant weight ( ).
[0020] 2. Methods and formulas for converting and simplifying plant traits into volume, weight and density: 2.1 Main stalk volume ratio: The plant height is the height from the ground to the top of the plant when viewed from the side, and the spread is the longest and widest distances of the surface where the leaves of the plant are located when viewed from above. The plant is simulated as a cylinder as a whole, and the plant volume is calculated according to the cylinder volume formula. The formula is: =π* * The main stalk height is the height from the main stalk root to the main stalk top when viewed from the front side, and the main stalk diameter is the diameter of the thickest part of the main stalk. The main stalk volume is calculated according to the cylindrical volume formula, which is: =π* * The main stalk volume ratio (main stalk volume / total plant volume) reflects the percentage of the main stalk in the plant volume. A large ratio indicates a high proportion of the main stalk and good development of the main stalk. A small ratio indicates a high proportion of leaves and good development of the leaves. The formula is: =(π* * ) / (π* * ).
[0021] 2.2 Stalk-leaf weight ratio The stalk-leaf weight ratio is the ratio of the main stalk weight to the leaf weight. A ratio of 1 indicates that the main stalk and the leaf weight are equal, a ratio less than 1 indicates that the leaf weight is large, and a ratio greater than 1 indicates that the main stalk weight is large. The formula is: = / .
[0022] 2.3 Density The density ρ is defined as the sum of the number of leaves, lateral branches, and main stalks divided by the plant volume to indicate the abundance of leaves, lateral branches, and main stalks within the plant volume. The formula is ρ=( + +1) / .
[0023] 3. Comparative classification evaluation After the botanical characteristics of each variety resource are calculated in Excel according to the above formula, they are listed in the Excel table according to the number and characteristics. According to the purpose of the investigation, they are compared, classified and evaluated according to volume, weight and density.
[0024] Table 1 is the botanical traits of 29 Chinese cabbage samples, and Table 2 is the classification table of physical properties of the botanical traits of 29 Chinese cabbage samples.
[0025] Table 1 Botanical characteristics of 29 Chinese flowering cabbage samples Table 2 Physical properties of 29 Chinese cabbage After directly converting the 9 botanical traits in Table 1 into the 3 physical traits in Table 2, the evaluation results divided the 29 varieties into 11 categories. The volume, main stalk weight and growth luxuriance of different resources can be distinguished intuitively. It has the advantages of being simple, batch, direct and intuitive. The analysis results are highly logical and credible, which is suitable for the preliminary analysis, comparison and evaluation of a large number of Chinese cabbage germplasm resources, saving a lot of time, manpower, financial and material resources, deepening perceptual understanding, lowering the threshold for plant diversity research, and objectively evaluating the plant diversity of Chinese cabbage.
[0026] The embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
