I'm trying to get just the orders of magnitude of this ratio in different kinds of crops, especially crops where the root is the main storage organ, versus crops that allocate most resources to leaves, fruit etc.
Thanks!
It is difficult to get information at one place. We need to scan literature crop wise for root shoot ration. It is good point to discussion. Let us have views.

It's a brilliant issue for discussion. I'm not certain about any typical root-shoot ration, but quite optimistic to have some significance of this type of ratios.
Let us go thorough related literature.
@ Yonatan. the ratio varies with the carbon allocation, therefore it depends on the environment and the crop genetic potential. The root to shoot ratio (R:S, defined as dry weight of root biomass divided by dry weight of shoot biomass) depends upon the partitioning of photosynthate which may be influenced by environmental stimuli. Therefore, if there is any least available, that is valid only for the particular climate. It may not be possible to generalize.
