Appearance of storage lipid (triglycerides) in somatic embryos of peanut (arachis hypogaea L.)

Summary We estimated the level of triglycerides (triacylglycerol) at intervals of 2 wk during somatic embryogenesis in peanut. The initial triglyceride content in the leaflet explants was depleted during the formation of embryogenic tissue. It increased with the onset of somatic embryogenesis. Concentration of triglyceride in a fully developed embryo increased further if incubated in the same dehydrated medium for a longer period of time. Transferring these embryos to fresh medium led to germination of somatic embryos with a depletion of storage lipids.
