Abstract: To further understand the morphological and structural diversity in early ontogeny of angiosperms,the developmental process and characteristics from zygote to seedling stage were studied. The results showedthat the embryo development of G. scabra belonged to Solanad type,endosperm development was nuclear type,the differentiation of seed embryo was incomplete when seeds scattered from the capsule,and most seedsdeveloped to the stage of heart-shaped embryos or torpedo embryos. When the seed germinated,the radiclerelied on the elongation of the hypocotyl cells to break through the seed coat,forming a root ring at the junctionof the hypocotyl and the radicle,and then the root ring hair developed on the root ring. The hair extension grewfaster than the radicle at the initial stage. In the development of the radicle,normal root hairs graduallyappeared at the tip. The seedlings in the cotyledon state were stagnated for at least 10 days before true leafdevelopment was seen,but while the growth was stagnant on the ground,the underground radicle continued togrow. The characteristics of these organ development sequences reflected the original aquatic relict of theancestors,and adapted to more arid habitats,which was the further evolution of the secondary terrestrialspecies.
