Scientific name: Parinari curatellifolia Family: Chrysobalanceae Common names: Mobola plum, grysappel, bosappel, Mmola, Mbulwa, Mobola, Muvhula, Umkhuna Origin and distribution Mobola plum is native to Africa. It is widely distrib- uted from Senegal and Kenya to the southern part of Mpumalanga and Swaziland, towards Zim- babwe and the northern part of Limpopo Province. Growing areas in South Africa It is found in the wild in Mpumalanga and Limpopo provinces. Description Mobola plum is an evergreen, tropical fruit tree with a mushroom-like shape and grows up to 20 m tall. Stem The stem is bare and dense, with a round to mush- room-shaped crown and branches that droop all around. At certain times of the year, particularly in hot weather, it can emit an unpleasant odour. Bark The bark is dark grey and rough. Leaves The leaves are dark green on top, hairy and grey to yellow underneath on a short petiole. Flowers Mobola plum flowers are small, white and sweet- scented and occur in short panicles (4 to 6 cm diameter) in the leaf axils. The stalks and calyx are covered with yellowish, woolly hairs. The bisexual flowers have five sepals, five petals, seven or more stamens and a two-chambered ovary. The sta- mens are joined at the base in a ring that is insert- ed into the mouth of the receptacle. Fruit Fruit is oval to round and 30 to 50 mm long, yellow- red in colour, turning brown as it ripens. It has a rough, scaly skin, with golden coloured warts on the surface. Climate and soil requirements, temperature The mobola plum is sensitive to extreme weather, such as frost and cold winds. It grows well at mean minimum and maximum temperatures of 10 ºC and 30 ºC, respectively. Rainfall Mobola plum mostly grows in areas with a mean annual rainfall of ±400 mm. Soil It prefers light yellowish-brown to reddish-yellow, sandy clay loams, red to dark red, friable clays with a laterite horizon, and yellow-red loamy sands. This tree occurs primarily on well-drained soils, fairly acid and sandy soils. Cultivation practices PROPAGATION The plant is propagated through seed, coppice or suckers. Soil preparation Soil preparation is best done a month or more be- fore planting so that the soil has time to settle. Dig a 60 cm deep by 1, 2 m square hole, incorporat- ing as much organic material as possible with the aim to get the soil into a crumbly texture. Planting Collect fresh seeds from the tree. Clean the flesh away and dry the seed in the shade. Pretreat the seed by immersing them in boiling water for 15 minutes and allowing them to cool and then soak- ing for 24 hours. Sow the seeds in river sand in a flat seedling tray. Press the seeds down until they are level with soil surface and cover with a thin layer of sand. Transplant the seedling into a nursery bag when they reach the 3-leaf stage. Transplant the seedling into the veld or garden after two years. Pest control Infestation of weevils’ larvae in the stone of P.cura- tellifolia destroys the seed and induces leaf drop. Nematodes and ground beetles (Carabids) can be used as biological control agents. The nema- todes can be introduced into the soil where they are active to feed on the weevil larvae. Ground beetles also feed on weevil grubs, pupae and
