Embodiment 1

[0050] figure 1 It is a flow chart of the method for determining the color change characteristics of Ranunculus ranunculus according to Embodiment 1 of the present invention

[0051] see figure 1 , the method for determining the color change characteristics of ranunculus ranunculus, comprising:

[0052] A method for determining the flower color variation characteristics of ranunculus, comprising:

[0053] Step 101: Obtain the flower color measurement values ​​of ranunculus that are measured by the colorimeter for multiple consecutive days.

[0054] This step 101 specifically includes:

[0055] Obtain the flower color brightness L of Ranunculus measured by the colorimeter in consecutive days * , flower color red and green degree a * and flower color yellow blue degree b * ;According to the flower color red and green degree a * and the flower color yellow-blue degree b * Calculate chroma According to the color brightness L * , the flower color red and green degree a ...

Embodiment 2

[0075] Select the top flower of the main stem of the ranunculus variety "Jiaoyan Yangpeony Brick Red", use a colorimeter to measure the color of the area to be tested at a fixed time every day, record the L*, a*, b* values, measure 3 times, and take the average value. In this example, the measurement time is from 9:30am to 10:00am, and the measurement time is from the opening of the outer petals to the loosening of the outer petals, and the measurement area is the center position of the upper third of the upper surface of the outer petals. On the basis of L*, a*, b* values, according to and Calculate the chroma C* and the color difference E*; according to where Y jv (t j ,t j+1 )=s v (t j ,t j+1 )·λ(a j ), Calculate and obtain the dynamic value of suit change. Table 1 is the dynamic value of the pattern change speed of the second embodiment.

Abstract

The invention discloses a method and a system for determining flower color change characteristics of Ranunculus japonicus. The method comprises the following steps of: obtaining flower color measurement values of Ranunculus japonicus measured continuously for a plurality of days; calculating the change speed of the pattern color corresponding to each pattern color measurement value according to the pattern color measurement value; the absolute value of the acceleration of pattern change corresponding to the measured value of each pattern color is calculated according to the pattern color change speed; calculating a velocity change state value of each pattern color measured value in two consecutive days according to the pattern color change speed; According to the absolute value of the acceleration of pattern color change, the trend value of each pattern color change speed in each day was calculated; calculating the eigenvalue of each color measurement on a daily basis according to thevelocity change state value and velocity change trend value; for each color measurement value, the daily variation eigenvalues are summed to obtain the variation dynamic value of each color measurement value. The method and the system of the invention can dynamically explain the changing state and the trend of the whole flower color of Ranunculus japonicus, thereby scientifically and accurately determining the flower color changing characteristics of Ranunculus japonicus.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method and system for determining the color change characteristics of ranunculus ranunculus. Background technique [0002] Ranunculus belongs to the genus Ranunculus in the family Ranunculaceae. It is a flower used in pots, cut flowers and flower beds that has developed rapidly in recent years. The annual sales volume of ranunculus in my country reaches 25-40 million cut flowers, and the profit is more than 45%. In developed regions such as Europe and Japan, the output and value of ranunculus in winter and spring have reached the second place in the cut flower market, occupying an important position in the international flower auction market, and have great research and application value. Ranunculus is rich in flower colors. In addition to common colors, it also has rare colors such as green, brown, and purple blue; the same color system has light, medium, and dark transition colo...
