Figure 8.16. The effect of the axis on protein mobilization in mung bean cotyledons. The embryonic
axis was carefuhy removed from dry seeds. The isolated cotyledons ( ) were placed on moist sand
and the intact seeds ( ) on wet vermiculite in darkness (where radicle emergence occurred).
Storage protein (A), proteinase (vicilin peptidohydrolase) (B). and free amino acids (C) were measured at daily intervals over 6 days. After Kem and Chrispeels (1978).
