What is the life cycle of sorghum?

Grain sorghum goes through three distinct stages of development after emergence – seedling development, panicle initiation and reproduction. The time required for the plant to go through each stage is dependent upon hybrid maturity and temperatures encountered during the growing season.

Is Sorghum bicolor invasive?

Sorghum halepense is an extremely invasive noxious weed with a worldwide distribution. High seed production and an extensive rhizomal system makes it difficult to eradicate.

Is Sorghum bicolor an annual or perennial?

Most varieties are annuals, but there are a few tropical perennial sorghums, and some folks have managed to hybridize annual grain sorghum (Sorghum bicolor subsp. bicolor) with cold-hardy wild perennial Johnson grass (Sorghum halepense). These rare perennials provide the basis for this collaborative effort.

What is meant by Sorghum bicolor?

Sorghum bicolor, commonly called sorghum (/ˈsɔːrɡəm/) and also known as great millet, durra, jowari / jowar, or milo, is a grass species cultivated for its grain, which is used for food for humans, animal feed, and ethanol production. S. bicolor is typically an annual, but some cultivars are perennial.

Plant growth and physiology 4.1 the sorghum plant The sorghum plant’s botanical name is Sorghum bicolor (L.) Moench, and it is a member of the Poaceae family. It is a perennial, tropical C4 grass capable of growing beyond physiological maturity of the grain.

When does the panicle of a sorghum plant bloom?

In fact, some hybrids begin blooming as soon as the panicle has completely emerged from the leaf sheath. STAGE 6: FLOWERING Flowering or blooming is the most critical stage in the life of the sorghum plant. A plant begins flowering from the top of the panicle and progresses downward.

What should the growth rate of sorghum be?

The rate of growth depends upon temperature and moisture primarily, but it can also be influenced by soil fertility, insect and disease damage. 2The optimum temperature range for growth is 12–34°C. Growth rates are very sensitive to temperature and moisture, as well as soil fertility and insect and disease damage.

What is the botanical name for sorghum grass?

The sorghum plant’s botanical name is Sorghum bicolor (L.) Moench, and it is a member of the Poaceae family. It is a perennial, tropical C4 grass capable of growing beyond physiological maturity of the grain. The hybrids available for grain production may be either determinate or indeterminate in setting the number of tillers for grain production.
