Nusantara Bioscience 9: 352-360. Ubi kuning is a local genotype of cassava with high beta carotene content but the development of this genotype is still low because of plant disease susceptibility. Objectives of this study were to robust induce and regenerate somatic embryos of ubi kuning in vitro as well as to define a protocol of cyclic somatic embryogenesis of ubi kuning. Different size of leaf lobes, various concentration of picloram and different light conditions were tested to produce an effective and efficient somatic embryos (SEs).The best response of the induction of embryogenic callus was observed in leaf lobes explant with range size of 1-3 mm and >5mm cultured on induction medium (MS + 4% sucrose + 4 μM CuSO4 + 0.1 mM Glutamine + 0.8% Microagar) supplemented with either 10 or 18 mg/L picloram grown under dark light for 4 weeks. Retransferring embryogenic callus to the same medium supplemented with 16 mg/L picloram gave the advanced development of primary somatic embryos (PSEs) after 70 d grown under both dark and light condition treatments. A positive correlation between globular and cotyledon stages was obtained in all treatments (P≤ 0.01). The highest shoot and root growth (30% and 25%) was achieved in the regeneration of cotyledonary like-tissues cultured on callus embryogenic media (CEM) (MS basal+ 2.5 μM CuSO4 + 3% sucrose + 2.75 g/L phytagel) supplemented with 1.6 mg/L of BAP (6-Benzylaminopurine).

Immersion Period

The cultivation of date palm in Indonesia has increased since the last decade. However, the superior date palm seedlings are still limited and most of them are imported from other countries. The mass supply of superior date palm seedlings can be provided by in vitro propagation in the bioreactor. Therefore, the research was conducted to develop a protocol of date palm in vitro propagation by using Temporary Immersion Bioreactor (TIB). The in vitro propagation was carried out through somatic embryogenesis technique using meristematic tissues isolated from offshoots of date palm female clone cv. Zambli as explants. The explants were sterilized and then cultured to produce embryogenic calli and somatic embryos. Afterwards, somatic embryos germination and plantlets formation were conducted in TIB with treatments of immersion period: 3, 10, and 30 minutes every 6 hours, with 8 replications, The results showed that the optimal somatic embryo germination in TIB was with the immersion period of 30 min every 6 h, resulting in the most formation of shoots and fresh biomass weight increment up to nearly threefold in 6 weeks. Thereafter, plantlets formation in TIB with immersion period of 10 min and 30 min every 6 h exhibited similar performances in producing more plantlets with higher total fresh weight and better vigor than those of 3 min every 6 h. However, there were more rooted plantlets in the TIB with immersion period of 10 min every 6 h. Based on the results, an in vitro propagation protocol via somatic embryogenesis in TIB has been successfully developed for mass propagation of date palm cv. Zambli, which produced plantlets with good vigor and rooting.
