A method of picking tomato seeds

Abstract

The invention relates to a method for extracting tomato seeds. The method comprises the following steps: carrying out short-time fast fermentation on an extracted tomato juice seed mixture with pulp and seeds under a seed extracting condition by adopting a mode of adding fermentation mother liquid, wherein the seed extracting condition comprise preparation of the fermentation mother liquid: after fermenting the tomato juice seed mixture with pulp and seeds, which is extracted in the first step, under the normal temperature for 18 to 20 hours, filtering by using a gauze, taking supernatant as the fermentation mother liquid, and preserving fresh supernatant which is fermented and filtered in the same day as next fermentation mother liquid every time; extracting the seeds and fermenting; after completely fermenting, cleanly washing by pouring into gauze cloth or carrying out rinsing and separating by putting into a centrifugal tomato seed separator, and then airing on the gauze or airing in a cool and dry place. According to the method for extracting the tomato seeds, disclosed by the invention, the time span of tomato seed extraction during a seed sampling period can be remarkably shortened, seed germination during the seed sampling period can be effectively avoided, and the seed quality and the seed sampling efficiency are increased.

Description

technical field [0001] The invention relates to the technical field of tomato breeding, in particular to a method for picking tomato seeds. Background technique [0002] The traditional artificial tomato seeding method is to cut the harvested mature tomato fruit from the middle, squeeze out and scrape the seeds in the seed cavity and put them in the container. Because there is a layer of pectin on the outside of the seeds, when the seeds in the cavity are squeezed out and scraped clean, the seeds will inevitably stick together with the pulp and juice to form a mixture of fleshy, seeded and placenta gelatinous substances. At the same time, this layer of pectin can Inhibit germination and make the seeds stick to each other, the seeds are not easy to wash out, so the unfermented seeds are difficult to handle. The fermentation process is very critical in the process of picking tomato seeds, especially in the process of artificial seed picking. The layer of pectin outside the se...

Problems solved by technology

When the varieties with few samples are fermented naturally, because the mixture of meat, seeds and placenta jelly is less, and the fermentation time is long, the mixture evaporates before the fermentation is complete, and high-quality seeds cannot be obtained.
