Summary: | At three stages of fruit ripening of three euonymus species (Euonymus sp.), growth parameters, the development of morphologo-anatomical structure, and the accumulation of neutral acylglycerols (NAG) of fatty acids were studied. It was established that, in all species studied, in the cells of endosperm and cotyledons, as well as in arillus cells, small oleosomes of similar size were formed, whereas in Euonymus europaeus and E. maximowiczianus large oleosomes differing in their sizes also appeared. Independently of fruit age, dry weight of seeds exceeded that of arils by several times. At the determination of separate NAG classes: TAG (1,2,3-triacyl-sn-glycerols) and acDAG (3-acetyl-1,2-diacyl-sn-glycerols), it was shown that the absolute content of acDAG in seeds was 1.5 orders of magnitude higher than that of TAG; in contrast, in arils TAG were much more abundant than acDAG. Euonymus species differed markedly in the growth pattern and NAG accumulation in seeds and arils. |
