Which plant is soybean?

Which plant is soybean?

soybean, (Glycine max), also called soja bean or soya bean, annual legume of the pea family (Fabaceae) and its edible seed. The soybean is economically the most important bean in the world, providing vegetable protein for millions of people and ingredients for hundreds of chemical products.

Do soybeans grow after flowering?

Soybeans are largely either indeterminate or determinate in growth habit. For indeterminate products, vegetative growth continues after flowering, and the rate of development is directly related to temperature. Determinate products generally complete vertical growth by the time flowering is completed.

When should soybeans flower?

Soybeans can begin flowering about a week before the summer solstice, but generally just after. This means that soybeans are photo period sensitive. They begin the reproductive stage when the nights become longer. They will put on viable flowers for about 50-60 days after.

How long will soybeans flower?

The first is that soybean will produce flowers for ~3 to five weeks, depending upon planting date and environment. Soybean will abort anywhere from 20 to 80% of the flowers that they produce. Generally it is the first and last flush of flowers produced that are most likely to be aborted.

Do soybean plants have purple flowers?

Elevated anthocyanin levels are more common in soybean cultivars with purple flowers, but can occur in cultivars with white flowers as well. Soybean plants with purple stems have been common across Indiana in 2006.

Is soybean a shrub?

The soybean plant is usually an erect bush with woody stems and alternately arranged leaves. Soybean is an annual plant, surviving only one growing season and can reach heights of 0.2–1.5 m (0.7–1.4 ft). Soybean may also be referred to as soyabean or soya and originates from Northeast China.

What color are soybean flowers?

Flower color of the wild relative of soybean, Glycine soja Sieb. & Zucc. is almost exclusively purple; by contrast, 33% (5,544 out of 16,855) of the soybean accessions in the USDA Soybean Germplasm Collections have white flowers (Dr. R.L. Nelson, personal communication 2006).

How many flowers do you get from a soybean plant?

Soybean Flowering From 3 to 15 flower buds develop at each node of the stem. There are two main types of soybean, depending on how flowering occurs. Varieties called indeterminate continue growing upward at the tip of the stem for several weeks after flowering begins lower on the stem.

How are soybeans pollinated?

Soybeans are self-fertilized and thus there is limited need for bee pollination by commercial farmers. Despite this, soybeans are visited by bees, including honey bees. Soybean nectar is a component of most honey produced in the Midwest. Soybean is also visited by other bees.

Do soybeans have white flowers?

The variety planted next to it had purple flowers. First, what color are soybean flowers? The answer is they can be various colors, ranging from white to purple.

What kind of flower does a soybean plant have?

Soybeans form inconspicuous, self-fertile flowers which are borne in the axil of the leaf and are white, pink or purple. Depending of the soybean variety, node growth may cease once flowering begins. Strains that continue nodal development after flowering are termed ” indeterminates ” and are best suited to climates with longer growing seasons.

Why does it take so long for soybeans to flower?

After flowering begins, temperature drives growth through pod development—the warmer the summer, the faster the plant develops. Soybean maturity will be delayed in soybeans that are grown near high intensity roadway lighting because plants perceive the artificial light as an extended day.

Where did the soybean plant originally come from?

Perennial soybean (Neonotonia wightii) originated in Africa and is now a widespread pasture crop in the tropics. Like some other crops of long domestication, the relationship of the modern soybean to wild-growing species can no longer be traced with any degree of certainty. It is a cultural variety with a very large number of cultivars.

When does the reproductive stage of a soybean plant begin?

The reproductive stages begin when the first flower is present on the plant (R1). The first flower is typically towards the bottom of the plant. As the plant moves into full bloom, it enters into R2. The reproductive stages include pod development (R3 and R4), seed development (R5 and R6), and finally maturity (R7 and R8).
