Abstract
Partial desiccation treatment was applied to improve plant regeneration of in vitro callus and embryo cultures of date palm cvs. Barhee and Malkaby. Desiccation was achieved by transferring undifferentiated callus and un-germinated embryos to Petri dishes with double layer of filter paper and then holding in the air current of Laminar flow cabinet for 0.0, 1.0, 2.0, 3.0 and 4.0 hours. After that, they were transferred to MS medium supplemented with 0.1mg/l NAA+ 0.05mg/l BA. Partial desiccation (3 and 4 hours) of callus cultures reduced fresh weight due to reduction of water content and stimulated callus growth, globularization and embryo formation of the two cultivars under investigation. The highest germination percentage was achieved when embryos were desiccated for three hours (83.33 and 60% for Malkaby and Barhee, respectively). Desiccation treatment reduced hyperhydricity. The study suggests that partial desiccation treatment can be useful in stimulating maturation and germination of date palm somatic embryos.
