项目摘要

Induction and the development of shoots, roots and somatic embryos was studied with morphology, ultrastructure and biochemistry. (1) Successuful germination of aged seeds was made by ABA and brassinolode. Embryoids were developed from millet seeds and subcultured resulting in plantlet formation. (2) Somatic embryos arose throught nucellus culture, anther culture and leaf segment culture of Malus. (3) Centripetal disposition of chloroplasts, mitochondria and microbodies was occurred in the bundle sheath cells during the development of Eleusine coracana leaves and its movement was inhibited by auxin, cycloheximide and cytochalasin B. (4) The activity of ADH in rice callus increased in the process of dedifferentiation. (5) When supplied from rice scutellum, IAA, ABA and brassinolide accelerated the seminal root growth but not from root medium.

通过形态学、超微结构和生物化学研究了芽、根和体细胞胚的诱导和发育。 (1)ABA和油菜素使老化种子成功发芽。胚状体由小米种子发育而来，并进行传代培养，从而形成幼苗。 (2)通过苹果属的珠心培养、花药培养和叶段培养产生体细胞胚。 (3)牛筋草叶片发育过程中束鞘细胞内叶绿体、线粒体和微体发生向心配置,其运动受到生长素、放线菌酮和细胞松弛素B的抑制。(4)水稻愈伤组织去分化过程中ADH活性增强。 (5)当从水稻盾片供给时，IAA、ABA和油菜素内酯加速了种子根的生长，但不是从根培养基供给的。
