Seed dispersal 
Seed Collection  Mature fruits are collected either from the clumps or from the ground by hand picking prior to the appearance of wrinkles on the seed coat (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002).
Transportation of seeds  Fruits collected in moist gunny bags are transported to the nursery as early as possible (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002).
Seed processing  Spread out the fruits in a ventilated room. No special processing is nacessary (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002).
Seed storage  Recalcitrant (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002). The seeds are viable for only 10 to 30 days and thus cannot be stored for long (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002)

Seed emptiness  No information (Chacko et al., 2002).
Seed pre treatment  Not required (Chacko et al., 2002).
Germination type  Hypogeal (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002).
Germination percentage  90 (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002).
Germination period  13 to 20 days (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002).
Nursery technique  Fresh seeds are sown horizontally soon after collection in raised nursery beds filled with soil and sand mixture under partial shade. Seedlings are pricked out when they are 5 to 6 cm tall and potted in polythene bags of 22.5 cm x 17.5 cm filled with soil. Seeds are also dibbled directly in polythene bags (Seethalakshmi and Muktesh Kumar, 1998; Chacko et al., 2002).

Vegetative propagation 
Pests  No information (Chacko et al., 2002).
