Embodiment 1

[0046] 1. Artificial accelerated aging test

[0047] The Jimai 22 wheat seeds were packed into nylon mesh bags, 500 grains per bag, 16 bags in total were labeled, and placed in a blast drying oven at 41° C. (relative humidity RH=98%). The seeds were aged for 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15 days respectively. After the aging, the seeds were taken out and dried back to the original weight at room temperature.

[0048] 2. Standard germination test

[0049] Take 300 grains for each of the above-mentioned treatments, and 100 grains constitute one repetition. Disinfect the seeds with 1% sodium hypochlorite for 5 minutes and rinse them three times.

[0050] This test adopts the paper bed germination method. Clean the germination box and sponge, soak the germination paper (USA Anchor Company, specification 25cm*38cm) and the sponge, put the germination paper on the sponge and put it into the germination box together.

[0051] Put the sterilized wheat seeds on...

Abstract

The invention provides a modeling method for measuring vitality of wheat seeds, and particularly relates to the technical field of seed vitality measuring. The invention provides the modeling method for measuring the vitality of the wheat seeds. The modeling method for measuring the vitality of the wheat seeds comprises the following steps of measuring the vitality of the seeds to obtain vitality index data, wherein the vitality index data comprises germination rate, germination potential, simple vitality indexes and fresh weight; dyeing the activated seeds by using a tetrazole solution to obtain dyed seeds; removing background colors and endosperm parts of scanning results after the dyed seeds are scanned, and extracting phenotypic characteristic data of seed embryo areas to obtain scanning data; and analyzing the scanning data and the vitality index data and establishing a regression model. Through a model constructed by using the modeling method for measuring the vitality of the wheat seeds, e the problem of too strong subjectivity of manual judgment can be reduced, and the advantage of simple operation is achieved.

Description

technical field [0001] The invention relates to the technical field of seed vigor measurement, in particular to a modeling method for measuring wheat seed vigor. Background technique [0002] Seed vigor is an important indicator of seed quality and quality, which is related to seed germination rate and emergence rate, seedling growth potential, plant stress resistance and production potential. The determination of seed vigor is also an indirect method to quickly identify the germination ability of seeds. Accurate vigor determination methods can truly reflect the germination ability and maximum germination potential of seeds, especially for some seeds with long dormancy period. [0003] At this stage, it takes a long time to measure germination force by conventional germination test, and the life span of seeds varies. In order to determine whether the seeds can be used for sowing and determine the sowing amount, it is necessary to carry out efficient measurement of seed viabi...
