Pruning
Prune Parinari robusta Oliv. var. klainei Aubrév. ex Pellegr. in early spring before the new growth begins. Prune any damaged, dead, or diseased branches to prevent the spread of infections. Trim the tree to shape it and remove any crossing branches that can rub against each other and cause wounds. Avoid heavy pruning that can stress the tree and affect its growth.
Propagation of Parinari robusta Oliv. var. klainei Aubrév. ex Pellegr.
Parinari robusta Oliv. var. klainei Aubrév. ex Pellegr., also known as African almond or false shea butter, is a popular tree species that is mainly propagated through sexual and asexual methods. The following are some of the common propagation methods:
Sexual Propagation:
Seeds are the primary source of propagation for Parinari robusta Oliv. var. klainei Aubrév. ex Pellegr. Seeds are obtained from the matured fruits that fall off the tree or are manually harvested. The collected seeds are then cleaned and disinfected in fungicide before planting. Germination is fast, and new plants can be seen within 2-3 weeks of planting.
Asexual Propagation:
Asexual propagation of Parinari robusta Oliv. var. klainei Aubrév. ex Pellegr. is mainly done through vegetative methods, which include grafting and cuttings.
Grafting is the most used method of asexual propagation, and it is mainly done during the rainy seasons. The scion, which is selected from a healthy plant, is grafted onto a rootstock of a closely related plant species. After grafting, the scion and the rootstock are wrapped in a polythene bag to prevent moisture loss, and the grafted plant is planted in a well-drained potting soil. The grafted plant is then maintained under shade for a few weeks until the graft union is established and starts to form new leaves.
Alternatively, stem cuttings can be used for asexual propagation. Cutting materials, preferably obtained from healthy plants, are treated with rooting hormones before planting them in a rooting medium with high water retention capabilities. The cuttings are kept under a misting environment and protected from extreme weather conditions and high winds. The rooting process takes about 4-6 weeks, and the plantlets are then transplanted into pots for further growth and development.
