Nicotiana glutinosa

Nicotiana glutinosa

Nicotiana glutinosa is a species of flowering plant in the nightshade family (Solanaceae). It is native to South America and is known for its sticky leaves and stems, which are covered in glandular trichomes. This plant is often used in tobacco research due to its resistance to certain diseases that affect other tobacco species.

Description

Nicotiana glutinosa is a herbaceous plant that can grow up to 1 meter in height. The leaves are broad, ovate, and covered with sticky glandular hairs. The flowers are tubular and can be pink, white, or purple, blooming in clusters at the top of the plant. The fruit is a capsule containing numerous small seeds.

Habitat and Distribution

This species is native to the mountainous regions of South America, particularly in countries like Peru, Bolivia, and Argentina. It thrives in well-drained soils and can often be found in disturbed areas, such as roadsides and fields.

Uses

Nicotiana glutinosa is primarily used in scientific research. Its resistance to certain pathogens makes it a valuable model for studying plant pathology and genetics. Additionally, it has been used in the development of transgenic plants for the production of pharmaceuticals.

Cultivation

The plant is relatively easy to cultivate and can be grown from seeds. It prefers full sun and well-drained soil. Regular watering is necessary, but the plant is tolerant of drought once established. It is also resistant to many common pests and diseases that affect other tobacco species.

Related Species

Nicotiana glutinosa is closely related to other species in the genus Nicotiana, including Nicotiana tabacum (common tobacco) and Nicotiana rustica (Aztec tobacco). These species share similar morphological characteristics but differ in their resistance to diseases and pests.
