AbstractIn the present study, the efficiency of two cryopreservation strategies for oil palm (Elaeis guineensis Jacq.) was compared. If extracted from rehydrated kernels, 65% of the embryos desiccated to around 0.3 g H2O/g DW developed into plantlets after cryopreservation. In contrast, only 25% of embryos (0.12 g H2O/g DW) extracted from cryopreserved dry kernels developed into plantlets. However, this value was increased to 63% if kernels were partially rehydrated before freezing until the water content of embryos reached 0.3 g H2O/g DW. This study emphasizes the importance of partial rehydration of oil palm embryos before cryopreservation.

ABSTRACT Oil palm is economically important as a crop with high oil production. Indirect somatic embryogenesis in oil palm requires a long time for callus induction and plant formation, and it is important to study the embryogenic potential of calli and the mechanisms of somatic embryogenesis. The aim of this study was to test different growth regulators and spermine in induction of embryogenic calli in root explants of oil palm (Elaeis guineensis Jacq). Apex root explants of approximately 0.5 cm were isolated from plants cultivated in vitro and inoculated in Y3 culture medium in the following treatments: A - without growth regulators; B - 1 mg.L-1 picloram (4-amino-3,5,6-trichloro-2-pyridinecarboxylic acid); C - 1 mg.L-1 picloram and 2 mg.L-1 2ip (2-isopentenyladenine); D - 2 mg.L-1 2ip; E - 1 mg.L-1 picloram and 2 mg.L-1 BAP (6-benzylaminopurine); F - 2 mg.L-1 BAP; and G - 14.5 mg.L-1 spermine. After six months of culturing, the calli induced in the treatments were analyzed by light microscopy. The calli induced in the treatments with 1 mg.L-1picloram (B) and treatment with 14.5 mg.L-1spermine (G) exhibited embryogenic characteristics, small and isodiametric cells, forming agglomerates, besides a large amount of starch. Calli of the best treatment (Y3 com 1 mg.L-1 de picloram) were inoculated in Y3 culture medium without addition of growth regulators. After eight months, calli were once more analyzed under light microscopy. All the treatments showed callus formation, except for treatments D and A. Calli of treatment B exhibited cells with embryogenic characteristics that developed somatic embryos.

Abstract The oil palm (Elaeis guineensis Jacq.) is a perennial woody oil crop in the Arecaceae family. Oil palm is well known for a long regeneration time, therefore, in vitro propagation received great enthusiasm from oil palm industries. Somatic embryogenesis (SE) has become one of the most promising clonal propagation techniques in recent times. This study was aimed to determine a protocol for micropropagation somatic embryogenesis from female inflorescences explants of oil palm. The explant used was obtained from the female inflorescences of the oil palm 2.5 years old Tenera variety. The basal media used was Y3 with the addition of the hormone 2,4-D with different concentrations (33,66,99 and 132 mg/L). Callus initiation was formed in 99 mg/L and 132 mg/L 2,4 – D concentration with the basal area and the percentage of callus formation is 31,25% and embryogenic callus was formed from primary callus development in the basal area of female florescence. Embryo somatic induction with cell suspension culture, because the liquid medium is more efficiently used in commercial-scale propagation. The embryogenic callus phase which is generally used in liquid medium is the nodular phase because it is still meristematic so that the potential for cell division is still high and can increase the percentage of embryogenic callus.
