The leaves have a gnegum high nutritional value and constitute an important source of protein, essential amino acids and mineral elements[ ].

Leafy stems remain fresh for at least a week after harvesting[ ]. The dry matter content of the fresh leaves is much higher than for other dark or medium green leaf vegetables. This gives a feeling of firmness during preparation, hence certain consumers consider the leaves as a substitute for meat[ ].

The leaves of this species are somewhat thinner africanumm paler than the dark green leaves of the related Gnetum buchholzianum[ ]. The mature seed is 15 – 15mm long, enclosed in a somewhat drupaceous orange-tinted gnetu.

The tubers are sometimes eaten – especially at times of scarcity[ ]. Climbing members of this genus growing in Asia yield a potable sap[ ]. This species should also be looked at in this respect[ ].

The leaves are chewed to mitigate the effects of drunkenness and they are taken as an enema against constipation[ ]. Applied externally, the chopped-up leaf serves as a dressing on warts and boils to hasten maturation[].

Gnetum africanum – Useful Tropical Plants

A plant of humid, lowland tropical rainforests, being found at elevations from afriicanum level to 1, metres[ ]. It grows best in areas where the annual rainfall is around 3, mm[ ]. Succeeds in dappled shade in the woodland. Plants growing in full sun produce thinner leaves which are not so well liked by consumers[ ]. The plant tolerates a range of habitats and environmental conditions[ ].

Cultivated plants need to be given some support, such as a tree, to grow into[ ]. The plant forms two distinct types of stem. Growing up from the base, the stems produce only small, scale-like leaves, and they grow rapidly towards the light. Higher up, side shoots are formed with fully-developed leaves[ ].

The plant continues to ggnetum during the dry season and new shoots may develop where the stem has been cut or where side shoots have been removed[ ]. New shoots are also formed from rhizomes that spread along the forest floor[ ]. Current methods of harvest from wild stands are very destructive[ ]. Controlled harvesting, in which only side shoots or parts of stems are collected, allows new shoots to develop where a stem has been cut or where side shoots have been removed[ ].

Preliminary observations indicate that 3 – 4 harvests per year are possible, still allowing for substantial regrowth. More frequent harvesting will result in thin leaves that are considered inferior[ ]. The first harvest may take place 6 – 9 months after planting.

The total lifespan of the plant is estimated at over 10 years[ ]. This may double in subsequent years[ ]. Under wild conditions, the plant grows and forms underground tubers or roots that store plant food reserves. These can remain alive for many years when the vegetation and the plant growth above ground are cleared gneetum the soil surface is laid bare[ ]. A dioecious species, both male and female forms need to be grown if fruit and seed are required.

Female plants are often have stronger stems, and are africajum vigorous and productive than male plants[]. Plants For A Future have a number of books available in paperback and digital form. Our new book to be released soon is Edible Shrubs.

Seed – difficult to germinate in nursery conditions, though the plants self-sow successfully in the wild[ ]. It is assumed that seeds need pre-treatment, such as passing through the intestines of a bird, fruit bat, squirrel or other animal, before they germinate[ ]. Seed is normally found only in the tree canopy[ ]. Seed collection is thus far from easy, a further reason why the plant is hardly cultivated[ ]. Methods of vegetative propagation using leafy stem cuttings have recently been developed.

It is recommended that leaf blades of cuttings be trimmed in half[ ]. Nursery beds under shade and made of well-decomposed sawdust or fine river sand can be used for propagation[ ]. Ectomycorrhizae assist the roots in absorption of nutrients; the most fnetum species reported is Scleroderma sinnamarense.

After about 6 weeks the rooted cuttings are transferred to polythene sleeves, bamboo pots or other containers where they remain for a further 2 – 3 months. Field planting, preferably next to a young tree or shrub, takes place at the beginning of the rainy season[ ].
