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.

Aim: This study evaluated efficient culture media for the regeneration of elite material through somatic embryogenesis from oil palm zygotic embryos. Methodology: For callus induction, zygotic embryos of four elite genotypes (G1-264T, G2-238DX17P, G3-37DX17P and G4-237T) were cultured on three basal media (Y3, MS and N6) with different auxin 2 mg l-1 (Picloram, 2,4-D and Dicamba) combinations. Subculture was made every month for three passages. It evaluated various callus characters. The embryogenic calli from callus induction media were transferred to the embryo maturation medium and subcultured until the polyembryoids formed. For shoot and root formation, somatic embryo clumps were transferred into regeneration media. In-vitro plantlets with well-grown roots were hardened in pots for six weeks and assessed clonal fidelity using polymorphic SSR primers. Results: Among the treatments, calli from N6+2,4-D, Y3+2,4-D and N6+Picloram showed the highest embryogenic callus potential. G4-237T induced more embryogenic calli (32.982) among genotypes, which was on par with G1-264T (24.196). Embryogenic calli grown on N6 media with Dicamba showed the highest proliferation rate (1.141). After 60 days of culture on regeneration media, the highest number of plantlets per somatic embryogenic clump was obtained from G1-264T on N6 media supplemented with Dicamba. Interpretation: Culture media salt concentration showed a significant difference among media by causing perturbations of auxin flow during somatic embryogenesis affecting callus induction, proliferation and plantlet regeneration. This may be useful for standardizing the genotype-specific regeneration media in oil palm.

ABSTRACT Oil palm is a woody monocot of economic importance due to high oil production from its fruits. Currently, the conventional method most used to propagate oil palm is seed germination, but success is limited by long time requirements and low germination percentage. An alternative for large-scale propagation of oil palm is the biotechnological technique of somatic embryogenesis. The rooting of plants germinated from somatic embryos is a difficult step, yet it is of great importance for later acclimatization and success in propagation. The aim of this study was to evaluate the effect of the auxins indole acetic acid (IAA) and indole butyric acid (IBA) on the rooting of somatic embryos of Tenera hybrid oil palm. Plants obtained by somatic embryogenesis were inoculated in modified MS medium with 10% sucrose and 0.6% agar and supplemented with IAA or IBA at concentrations of 5 µM, 10 µM, and 15 µM, and the absence of growth regulators. After 120 days, the presence of roots, root type, length of the longest root, number of roots, number of leaves, and shoot length were analyzed. Growth regulators were favorable to rooting; plants cultivated with IBA growth regulator at 15 µM showed higher rooting percentage (87%) and better results for the parameters of number of roots (1.33) and shoot length (9.83).

AbstractAuxin affects the growth and development of in vitro plantlets including root induction. An experiment was conducted to determine the combination and concentration of auxin for rooting of oil palm plantlets in liquid medium.Unrooted plantlets of oil palm MK 649 clone with height 6 – 7 cm and 2 – 3 leaves were used as material source. The plantlets were cultured in de Fossard liquid medium. The treatments used were combinations of NAA and IBA at 0, 5,10 and 20 μM. The results show that 10 μM NAA combined with 20 μM IBA gave the highest percentage of rooting of oil palm plantlets (73.3%) in 10 weeks. NAA and IBA concentration influenced significantly rooting percentageand root quality and there was a significant interaction between the two auxins. Root initiation response of oil palm plantlets to NAA was higher than to IBA. The best of oil palm root class which indicates root quality was obtained in a medium with 10 μM NAA + 20 μM IBA. The aerial parts of the plantlets grew well in term of shoot height, leaf number and shoot diameter especially in a medium with 10 μM NAA + 20 μM IBA. AbstrakAuksin berpengaruh terhadap pertumbuhan dan perkembangan planlet in vitro, termasuk terhadap induksi akar. Penelitian ini bertujuan untuk menentukan kombinasi dan konsentrasi auksin yang tepat dalam pembentukan akarplanlet kelapa sawit in vitro dalam medium cair. Bahan yang digunakan berupa planlet kelapa sawit klon MK 649 tanpa akar dengan tinggi 6 – 7 cm dan jumlah daun 2 – 3 helai. Planlet dikulturkan dalam medium de Fossard cair. Perlakuan yang digunakan adalah kombinasi NAA dan IBA dengan konsentrasi 0, 5, 10 dan 20 μM. Hasil penelitian menunjukkan bahwa perlakuan NAA 10 μM dikombinasikan dengan IBA 20 μM menghasilkan persentase pembentukan akar planlet kelapa sawit tertinggi yaitu 73,3% dalam waktu 10 minggu. Konsentrasi NAA dan IBA secara nyata mempengaruhi persentase pembentukan dan kualitas akar serta terdapat interaksi yang nyata antara kedua perlakuan auksin. Respons induksi akar kelapa sawit terhadap NAA lebih tinggi daripada IBA. Kelas akar planlet kelapa sawit terbaik yang menunjukkan kualitas perakaran, juga diperoleh pada NAA 10 μM dan IBA 20 μM. Pertumbuhan dan perkembangan organ bagian atas yang meliputi tinggi tunas, jumlah daun dan diameter tunas menunjukkan peningkatan yang cukup baik terutama pada perlakuan NAA 10 μM + IBA 20 μM.
