The gel that surrounds the tomato seed contains chemicals that prevent seed germination. This may seem counterintuitive, but many seeds come equipped with mechanisms that stall germination until the time is right.

The ‘Do Nothing’ Method You extract the seeds, wash them under running water and dry them. Don’t use a paper towel because the gel around each seed sticks tightly to the paper once it is dry. To reduce this sticking problem use wax paper or a ceramic dinner plate.

Abstract. In tomato (Solanum lycopersicum) fruit, the number of locules (cavities containing seeds that are derived from carpels) varies from two to up to 10 or more. Locule number affects fruit shape and size and is controlled by several quantitative trait loci (QTLs).

Tomato is the same as a berry. It is developed from multicarpellary syncarpous gynoecium. The endocarp and mesocarp are fused to form a pulp. Because of the pericarp and the skin, the tomato is fleshy.

Ideally, tomato seeds are dried to preserve them for storage before the next planting season. During this time, the seeds are dormant. However, gardeners advocate that before planting, it is important to soak your seeds before planting.

Arabidopsis seed coat mucilage represents a very promising model system to explore secondary cell wall polysaccharides biosynthesis. Once extruded, the non-adherent outer layer mucilage is easily removed by gently shaking in water. However, the adherent mucilage is recalcitrant to chemical agents and vigorous shaking.

How To Save Tomato Seeds

1. Remove the Seeds: Select very ripe tomatoes and wash them.
2. Ferment the Seeds: Let the jars sit at room temperature (ideally between 70 to 80 degrees F) for 1-2 days to let them ferment (if the room temperature is cool it may take an extra day or two.

Our tomato slice is divided into four irregularly shaped compartments, called carpels. Our Standard Blossom’s ovaries have 5 equally sized and shaped carpels, but ovaries of flowers in other species may have more or fewer, and many display just one compartment, thus showing no subdivision at all.

Every tomato seed has a tiny tomato plant inside. When the conditions are just right, tomato seeds will germinate. As the seed germinates, the radicle or young root first appears and grows down into the ground. The cotyledons or seed leaves then appear and grow up towards the Sun and the young plant develops true leaves.

Anatomy of a Tomato Plant. As with all organisms, a tomato’s primary objective is to reproduce and carry on its genetic line. Every element of the plant’s anatomy is designed to reach this goal. Roots seek out water and nutrients, which the semi-woody main stem carries through vascular tissues to the leaves, flowers and developing fruit.

The female reproductive organ, the ovary, is located at the base of the pistil. The ovary contains the ovules. Once the ovules are fertilized, an embryo can develop and form seeds that will be found inside the tomato fruit.

Nearer to the skin of the tomato are the vascular bundles, which carry water and nutrients to the interior of the fruit, which are enclosed in the pericarp, or outer flesh of the tomato. Michelle Z. Donahue has worked as a journalist in the Washington, D.C., region since 2001.
