Propagation of Gliricidia sepium
Gliricidia sepium, commonly known as madre cacao or quickstick, is a fast-growing, medium-sized, leguminous tree that is highly valued for various purposes, including reforestation, erosion control, agroforestry, fodder, and medicine. Propagation of this plant is relatively easy and can be done using several methods, including seeds, cuttings, and root suckers.
Propagation by Seeds
Propagation of Gliricidia sepium by seeds is the most common method. The seeds are collected from mature pods that turn brown and start to split open. The seeds are then washed, dried, and stored in a cool and dry place. Before sowing, the seeds are treated with hot water or sulfuric acid for 10-15 minutes to break the hard seed coat and improve germination. The treated seeds are then sown in seedbeds or containers filled with a well-draining potting mix and kept moist. The seeds usually germinate within 7-14 days.
Propagation by Cuttings
Propagation of Gliricidia sepium by cuttings is relatively easy and results in faster growth compared to propagation by seeds. Stem cuttings of about 30-40 cm long and 1-2 cm in diameter are collected from healthy and mature plants during the dormant season. The lower leaves are removed, and the cut end is dipped in rooting hormone powder. The cuttings are then planted in a well-draining potting mix and kept moist. The cuttings usually root within 2-3 weeks and can be transplanted to a larger container or directly to the field.
Propagation by Root Suckers
Propagation of Gliricidia sepium by root suckers involves digging up the plant and cutting off the young shoots that emerge from the roots. The cuttings are then planted in a well-draining potting mix and kept moist until they develop a good root system. The plants can then be transplanted to the field. This method of propagation is advantageous as it results in genetically similar offspring and helps maintain the desired characteristics of the parent plant.
Disease and Pest Management for Gliricidia sepium
Gliricidia sepium, commonly known as quickstick or madre de cacao, is a multipurpose tree species widely used for its medicinal, agricultural, and industrial purposes. However, like any other plant, it is susceptible to various diseases and pests that can negatively affect its growth and yield. Therefore, it is crucial to implement disease and pest management strategies to ensure the healthy growth of the plant.
Common diseases affecting Gliricidia sepium
The most common diseases that affect Gliricidia sepium are leaf spots, stem cankers, and root rot. Leaf spots are caused by fungal or bacterial infections and appear as small brown or black spots on leaves. Stem cankers, on the other hand, are caused by bacteria or fungi that attack the bark and wood, leading to the formation of sunken lesions and the wilting of shoots. Root rot is caused by soil-borne fungi that attack the roots, causing them to rot and leading to the wilting and death of the plant.
Disease management strategies
To manage these diseases, it is crucial to plant disease-free and healthy seedlings. Proper sanitation and hygiene practices should also be implemented, such as removing and destroying infected plant parts and disinfecting tools and equipment. Fungicides can also be applied to control fungal infections, while bactericides can be used to control bacterial infections.
Common pests affecting Gliricidia sepium
