Problems solved by technology

With the increase of the number of branches, the number of leaves may increase, and the utilization rate of the light environment will increase, but the further increase of the number of branches will increase the competition between the leaves of the plant for the light environment, and ultimately limit the growth and development of the plant

Embodiment 1

[0022] Example 1: Detection of apical dominance in peas

[0023] After the plants were decapped, the growth of axillary buds was observed and recorded. Scan, record and measure each axillary bud according to the following method.

[0024] (1) Fix the paper with the line drawn on the glass culture dish to make a line drawing board;

[0025] (2) Put the ruler on the scanner and scan it into an image to obtain the ruler picture;

[0026] (3) Cut pea axillary buds from the main stem, and place each section of axillary buds on the line drawing board in the order of the nodes;

[0027] (4) According to the order of the sections, each section of the axillary buds is gradually transferred to the scanner and scanned into an image to obtain a picture of the axillary buds;

[0028] (5) Utilize ImageJ image processing software to process image, specifically:

[0029] A. Run the ImageJ software, open the scale picture, use the straight line tool to select a distance of more than 3cm fr...

Embodiment 2

[0033] Example 2: Evaluation of the effect of boron treatment on pea growth.

[0034] Pea seedlings in the normal boron concentration (25μmol.L -1 ) and a boron-deficient environment for about 3 weeks, according to the above-mentioned method, the axillary buds of the differently treated plants were placed in order of nodes, and the growth conditions were recorded. From figure 2 It can be seen intuitively that the apical dominance of boron-deficient plants is removed, the terminal buds wither, the axillary buds develop, and the reproductive development is inhibited (no flower buds) (in figure 2 Among them, node 0 is the pea cotyledon insertion point, node 1 is the first node, and so on; pea axillary buds are placed in the order of nodes. The measurement and statistics of bud length do not include the flower buds developed after 7 / 8 nodes treated with boron).

[0035] The length of axillary buds at each node was analyzed, and it was found that the differences in the growth ...

Abstract

The invention discloses a method for evaluating the growth condition of peas. The method comprises the following steps of (1) fixing paper with drawn row lines on a culture dish to make a line drawingplate; (2) placing a ruler on a scanner, and scanning the ruler into an image to obtain a ruler picture; (3) cutting the axillary buds of the peas from the main stems, and placing all the sections ofaxillary buds on the line drawing plate according to a sequence of the sections; (4) gradually transferring all the sections of axillary buds to the scanner according to the sequence of the sections,and scanning the axillary buds into images to obtain axillary bud pictures; and (5) processing the images by using image processing software ImageJ. The evaluation method is high in accuracy and small in error, a large number of samples can be processed in a short time, time and labor are saved, the branch condition is visually reflected, and scientific research and propagation of scientific ideas are facilitated.

Description

【Technical field】 [0001] The invention relates to the field of agricultural planting, in particular to a method for evaluating the growth of peas. 【Background technique】 [0002] Pea is one of the four major edible legume crops in the world. It is rich in starch and protein, and has a low fat content. It is widely used in fields such as grain, vegetables, non-staple food, feed, green manure and land crops. Pea has relatively comprehensive and balanced nutrition. The biological value (BV) of pea protein is 48% to 64%, and the efficiency ratio (PERK is 0.6 to 1.2. Pea protein is rich in lysine, which can be used as a source of lysine. Good raw material. At the same time, because pea contains a large number of chemical components with medical effects, it has been applied to the field of medical care. At present, pea has become an important raw material in medicine, feed, food and other industries, and is also an important test material for environmental monitoring. [0003] As...
