Quiescent seeds of Dalbergia miscolobium Benth. were shown to contain lipids and proteins as major storage components in cotyledons and embryos as well. The variations in these compounds were analyzed in four well defined morpho-physiological stages during germination and early plantlet growth. Extractable proteins increasead but their electrophoretic pattern did not change considerably during the observation period which lasted for 12 days after the beginning of imbibition. Decrease in lipid content was first detected in the embryo and subsequently in the cotyledons. The fatty acid composition differed in embryo and cotyledons, the former presenting high proportion of linolenic acid which was essentially absent in the colyledons. The importance of lipid content and composition is discussed in terms of its role as storage compound and in relation to the temperature and humidity conditions prevailing in the Cerrado areas where the plants occur. |
