Influences of Stock and Scion on Alkaloid Synthesis and Transformation.

It is desirable and necessary to reexamine the influences of stock andl scion oIn alkaloid synthesis and transformation using plants which behave differently witlh respect to alkaloid formation (4). Experiments were conducted in the greenhouse for 3 years in an attempt to separate the effects of root, or stock, from those of the top, or scioIn, on alkaloid synthesis and transformation. Some of the grafting combinations reported in this paper resenmbled those prepared previously by Dawson (2), but plants witlh various degrees of ability in alkaloid synthesis were included in this study.
