Embodiment 1

[0017] In this example, representative resources of three varieties of pear trees, namely June fresh pear, Nanguo pear and Puchengxue, were selected for rapid identification of resistance to rot, including the following steps:

[0018] (1) Take the annual dormant branches of the above-mentioned two pear tree varieties from the time when the leaves fall to before the germination, and peel off the epidermis in the middle of the branches. The area of ​​the epidermis is about 1 square centimeter, and the epidermis is fixed with transparent glue On white paper, repeat 5 times;

[0019] a. Scan the epidermis fixed on the white paper with a scanner of 300bpi precision, and save the image;

[0020] b. Use photoshop image processing software to select a unit skin area with evenly distributed lenticels with a square selection tool, and check the pixel value Sa of the unit skin area in the "Histogram" column in the "Image" menu;

[0021] c. Increase the "Brightness" and "Contrast" of th...

Embodiment 2

[0028] In this embodiment, 38 representative resources of pear tree varieties are selected, involving 12 species and an interspecific hybrid in different countries and regions, and the degree of resistance to rot of these 38 pear tree variety resources is identified, including the following steps:

[0029] (1) Select the above 38 representative resources of pear tree varieties in December, take 3 annual dormant branches around the canopy, peel off the epidermis in the middle of the branches, and use transparent adhesive to fix the epidermis on white on paper

[0030] a. Scan the epidermis fixed on the white paper with a scanner of 300bpi precision, and save the image;

[0031] b. Use photoshop image processing software to select a unit skin area with evenly distributed lenticels with a square selection tool, and check the pixel value Sa of the unit skin area in the "Histogram" column in the "Image" menu;

[0032] c. Increase the "Brightness" and "Contrast" of the image, selec...

Abstract

The invention discloses a method for quickly identifying pear rotting-resistant disease. The method includes utilizing a rule that 'lenticel relative area' of one-year-old pear dormant branches and disease attack degree of an artificially-inoculated tree are obviously in position correlation to select the one-year-old pear dormant branches, and grading the rotting-resistant disease of the pear by testing the 'lenticel relative area' of epidermis of the branches. Compared with the prior art, the method has the advantages of quickness, simplicity, convenience and high efficiency.

Description

technical field [0001] The invention relates to a method for identifying pear tree diseases, in particular to a rapid identification method for pear tree rot resistance. Background technique [0002] Pear tree rot occurs in all major pear producing areas in my country, especially in Xinjiang, Northwest, North China and other places. According to the current survey, the rate of diseased strains of Korla fragrant pears in Xinjiang has reached 50% to 80%, and the rate of diseased strains of crisp pears in Northwest China has reached 30% to 50%. Rot disease has the characteristics of wide occurrence area, high incidence rate, and difficulty in control. In pear orchards with serious incidence, the trees are full of diseased scars, incomplete branches, and even cause a large number of dead trees or destroyed orchards, which seriously threatens the healthy development of my country's pear industry. . [0003] Through the development of new technologies and the integration of vario...
