Abstract: | The annual dynamics of the amount of acylglycerols in the phloem of the Siberian larch has been established. It has been shown that, depending on the phenological state of the wood their amount varies between 0.192 and 1.435%. The triacylglycerols of the phloem form the bulk of the acylglycerols of this tissue over the whole of the annual cycle. The stereovariety composition of the triacylglycerls of the phloem has been studied by the method of stereospecific analysis. It has been established that they have an asymmetric structure. The bulk of them contains acylglycerols in the molecules of which the sn-2 positions are acylated by unsaturated acids.Siberian Technological Institute, Krasnoyarsk.
