In Vitro Flowering and Fruit Setting of Oil Palm Elaeis guineensis Jacq.

In vitro flowering and fruit setting was firstly reported in oil palm micropropagation. Vitroflowering at 10.2% was obtained in MS medium supplemented with 12 mg/l paclobutrazol (PBZ), 8 mg/l α-naphthaleneacetic acid (NAA) in the presence of high concentration of sucrose (7%). However, long term culture of seedlings or plantlets in vitro is needed. Practically, 6 months of culture with routine subculture at monthly intervals was observed. Upon two consecutive subcultures (two months) of vitro-flowering plantlets to ARDA medium efficient fruit setting was obtained. The fruits were small in size with three lobe of stigma. Long section of the fruits revealed only mesocarp without seed. This suggest that fruits might develop parthenocapically.
