Induction of useful crop organs through morphogenesis researches.

从形态学、超微结构和生物化学等方面对不定芽、根和体细胞胚的诱导和发育进行了研究。(1)阿坝和油菜素内酯使老化种子成功萌发。胚状体是从谷子种子中发育出来的，继代培养后形成小植株。(2)苹果属植物的体细胞胚在珠心培养、花药培养和叶段培养中都有发生。(3)在牛筋草叶片发育过程中，维管束鞘细胞中的叶绿体、线粒体和微体发生向心性的运动，生长素、放线菌酮和细胞松弛素B抑制了它们的运动。(4)水稻愈伤组织在脱分化过程中ADH活性升高。(5)从水稻小盾片中供给IAA、阿坝和芸苔素对种子根的生长有促进作用，而从根系培养基中供给则无此作用。

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.
