When leaves of Bryophyllum marnierianum are detached from the plant, plantlets develop from primordia located at their margins. Leaves excised with a piece of stem attached do not produce plantlets. Severing the major leaf veins overcomes the inhibitory effect of the attached stem, indicating that the control agent is transmitted through the vascular system. A possible mechanism is that an inhi...
Genetic engineering technology has been successfully used in many plant species, but is limited in woody plants, especially in bamboos. Ma bamboo (Dendrocalamus latiflorus Munro) is one of the most important bamboo species in Asia, and its genetic improvement was largely restricted by the lack of an efficient regeneration and transformation method. Here we reported a plantlet regeneration and A...
Most of the microspore-derived embryos can not regenerate normally in rapeseed. The effects of gibberellins (GA3), abscisic acid (ABA), and embryo desiccation on normal plantlet regeneration were studied. The donor plants were grown in a growth chamber at day/night temperatures of 15/10˚C with a 16/8h photoperiod, respectively. Microspores were isolated from whole buds of 2.5-3.5mm in length, c...
Experiments were carried out for optimization of conditions for morphogenic callus production and regeneration of carrot (Daucus carota L.) using four cultivated cultivars in Iran. Hypocotyl segments were cultured on medium supplemented with 0.2 mg/l 2,4-D for callus initiation and proliferation. Small portions of calli (25 mg) were cut and transferred to new media with different concentrations...
