The leaves are simple, alternate and elliptical in shape, measuring up to 23 cm in length and 11 cm in width. The margins of the leaves are entire with a shiny dark green surface and prominent veins.
The flowers of Solanum hypopsilum Bitter are hermaphroditic and form clusters of 10 to 15 flowers per inflorescence. The flowers are petiolate, pentamerous, and measure up to 2 cm in diameter with a diameter of 2 cm. The corolla is white and has 5 petals and a yellowish green color in the center.
Uses
The fruits of Solanum hypopsilum Bitter are edible and are commonly consumed in Bolivia. They resemble figs and have a sweet and sour flavor. The plant is also used in traditional Bolivian medicine to treat various ailments such as digestive problems, respiratory issues, and skin diseases.
Additionally, the leaves and stems of Solanum hypopsilum Bitter have been shown to have potent antioxidant and anti-inflammatory properties. This makes it a promising candidate for the development of natural remedies for the treatment of various diseases.
Light Requirements
Solanum hypopsilum Bitter requires a lot of light to grow properly. It needs around 8 to 10 hours of direct sunlight daily. However, during the hottest parts of the day, some shade may be necessary to prevent the leaves from burning. If grown indoors, it is essential to place the plant near a sunny window or under grow lights.
Temperature Requirements
The ideal temperature range for Solanum hypopsilum Bitter is between 60°F and 80°F (15°C to 27°C); however, it can tolerate temperatures slightly higher or lower than this range. It is important to keep the plant away from drafts, as temperature fluctuations can damage the plant. The plant will not survive in freezing temperatures and should be moved indoors during winter if grown in colder climates.
Soil Requirements
Solanum hypopsilum Bitter prefers well-draining soil that is slightly acidic with a pH range of 5.5 to 6.5. It is best to fertilize the plant during the growing season with a balanced fertilizer. The plant also thrives in nutrient-rich soil that is high in organic matter such as compost or leaf mold. When grown in containers, it is important to choose a pot with good drainage holes to prevent water buildup, which can cause root rot.
Cultivation Methods
Solanum hypopsilum Bitter can be grown in well-drained soils that are rich in organic matter. The plant prefers full sunlight and moderate temperature. It can be propagated through stem cuttings, seeds, and suckers. For propagation through stem cuttings, choose healthy stems with a few leaves and dip the cuttings in rooting hormone before planting them in a rooting medium.
Watering Needs
During the growing season, Solanum hypopsilum Bitter requires moderate watering. Overwatering can lead to root rot, and under-watering can cause the leaves to wilt. Watering should be done in the morning or evening to avoid the hot sun. It is advisable to water the plant deeply once a week rather than frequent, shallow watering.
Fertilization
For healthy growth and plant development, it is advisable to fertilize Solanum hypopsilum Bitter with a balanced fertilizer. Apply fertilizer during the growing season, preferably after every six weeks. Apply the recommended amount of fertilizer according to the manufacturer's instructions and carefully spread it around the base of the plant, avoiding contact with the leaves.
Pruning
Solanum hypopsilum Bitter needs to be pruned regularly to maintain its shape and control its height. Pruning should be done during the dormant season to avoid damaging the active growth parts. Cut off the damaged, diseased, or dead parts of the plant. Use sterilized pruning tools to avoid introducing infections to the plant. In addition, remove the suckers regularly to prevent overcrowding of the plant.
Propagation of Solanum hypopsilum Bitter
Solanum hypopsilum Bitter is a rare plant species endemic to Ecuador. Propagating the species can help in the conservation of the plant. The plant can be propagated in several ways, including:
Seed propagation
Seed propagation is one of the most common methods of propagating Solanum hypopsilum. The seeds should be harvested from mature fruits at any time during the fruiting season and sown immediately. The ideal medium should be light but nutrient-rich. Seedlings require a lot of light and humidity to grow. They should be transplanted to individual pots when they are about two months old.
Cutting propagation
Another method of propagating Solanum hypopsilum is through cutting. The cuttings should be taken from the stem tips, removing all the leaves except the top pair. The cuttings should be dipped in hormone rooting powder and planted in a well-draining medium. The pots should then be covered with a plastic bag to maintain humidity and warmth. Cuttings will take several weeks to develop roots and should be transplanted to individual pots when they are about two to three months old.
Tissue culture propagation
Tissue culture propagation is also an effective method of propagating Solanum hypopsilum, especially in large-scale production. This method involves taking tiny pieces of plant tissues and culturing them in a nutrient-rich medium. The tissue culture is then transplanted to a growing medium and covered to create a humid environment. The plantlets can be transplanted to individual pots when they are about three to four months old.
Overall, several effective methods can be used to propagate Solanum hypopsilum Bitter. The propagation technique chosen depends on factors such as the resources available, time available, and the desired outcome.
Disease Management
Solanum hypopsilum Bitter is vulnerable to several diseases, which include:
- Phytophthora root rot: This disease is caused by Phytophthora infestans. Symptoms include root rotting and stem girdling. To manage this disease, it is recommended to avoid planting in poorly drained soils and treating the soil with fungicides.
- Bacterial wilt: This disease is caused by Ralstonia solanacearum. Symptoms include wilting and death of the whole plant. To manage this disease, it is recommended to use disease-free seeds or seedlings, avoid planting in infected soils, and removing infected plants immediately.
- Early blight: This disease is caused by Alternaria solani. Symptoms include dark brown spots on leaves and fruits. To manage this disease, it is recommended to practice crop rotation, removing infected leaves, and managing irrigation to avoid creating a wet environment.
Pest Management
Solanum hypopsilum Bitter is vulnerable to several pests, which include:
- Aphids: These small insects suck the sap of the plant, causing stunting and yellowing of the leaves. To manage aphids, it is recommended to remove them by hand, use insecticidal soap, or introduce natural predators like ladybugs.
- Spider mites: These tiny pests suck the sap from the plant and leave a fine webbing on the leaves. To manage spider mites, it is recommended to spray the plant with water to wash them off, use insecticidal soap, or introduce natural predators like predatory mites.
- Leaf miners: These pests lay their eggs on the leaves, and the larvae tunnel through the leaf tissue, leaving brown trails. To manage leaf miners, it is recommended to remove infected leaves, use insecticidal soap, or introduce natural predators like parasitic wasps.
