specific Embodiment 1

[0061] Select the flower bud at the top of the main stem of the double-petaled ranunculus variety "Jianyan Yangpeony Brick Red", and determine the time when the calyx loosens as the first day. Determined as the test area, such as figure 2 As shown, during the period from 9:30am to 10:00am, use a colorimeter to measure the color of the area, record the L*, a*, b* values, measure 3 times, and take the average value. Using the same color measurement method, measure and record L*, a*, b* values ​​at a fixed time (9:30am-10:00am) every two days, and from the seventh day onwards, the time interval becomes every day. Organize L*, a*, b* values, on the one hand according to Calculate chroma and color values ​​C* and E*; on the one hand according to Y jv =s v (t j ,t j+1 )·λ(a j ), calculate the change speed dynamic value Y of E* jv , as shown in Table 1 and Figure 4 shown. in, Among them, Y jv Indicates the dynamic value of the change speed, s v (t j ,t j+1 ) rep...

Embodiment 2

[0067] Select the flower bud at the top of the main stem of the ranunculus variety "Delicate Peony Magenta", and determine the time when the calyx is loosely unfolded as the first day. According to the requirements of the DUS test guidelines, determine the center position of the upper third of the outer petal surface as the test area, such as figure 2 As shown, during the period from 9:30am to 10:00am, use a colorimeter to measure the color of the area, record the L*, a*, b* values, measure 3 times, and take the average value. Using the same color measurement method, measure and record L*, a*, b* values ​​at a fixed time (9:30am-10:00am) every two days, and from the seventh day onwards, the time interval becomes every day. Organize L*, a*, b* values, on the one hand according to Calculate chroma and color values ​​C* and E*; on the one hand according to Y jv =s v (t j ,t j+1 )·λ(a j ), calculate the change speed dynamic value Y of E* jv , as shown in Table 2 and Fig...

Abstract

The invention discloses a method and system for determining a flower color test period of persian buttercup. The method comprises the following steps: determining a test area of persian buttercup to be tested; measuring brightness, redness-greenness and yellowness-blueness of the test area by a colorimeter; calculating a chroma and a color value according to the brightness, the redness-greenness and the yellowness-blueness; calculating a change rate dynamic value of the color value in each florescence phase of the persian buttercup to be tested according to a change rate dynamic model; determining a first period, wherein the first period indicates three continuous phases in which the sum of absolute values of the change rate dynamic values is minimum; and selecting a phase in which the absolute value of the change rate dynamic value is minimum in the first period as a second period, wherein the second period is the flower color test period of the persian buttercup to be tested. By adoption of the method and system disclosed by the invention, the problem of lacking a flower color DUS test sampling period of the persian buttercup at present is overcome, and a scientific and accurateflower color test sampling period method is provided.

Description

technical field [0001] The invention relates to the field of determination of the sampling period for a flower color test, in particular to a method and system for determining the period of a ranunculus flower color test. Background technique [0002] Ranunculus belongs to the genus Ranunculus in the family Ranunculaceae, and it is a flower used in potted plants, cut flowers and flower beds that has developed rapidly in recent years. Ranunculus ranunculus has a wide range of flower color traits. In addition to common color systems, it also has rare color systems such as green, brown, and purple blue; the same color system has light, medium, and dark transition colors. Like other ornamental plants, ranunculus flowers change color continuously throughout the flowering process. However, the Ranunculus DUS test guidelines do not clearly indicate the specific period of the flower color test. The flower color data obtained at different periods in the flowering process are obviou...
