Stachyose: an early product of photosynthesis in squash leaves.
It was hypothesized that stachyose is translocated by squash because stachyose is supplied to the phloem loading system by the photosynthetic system. To test this hypothesis, (14)CO(2) was supplied to squash leaves. The nonphosphorylated sugars containing (14)C were studied. A large proportion of (14)C appeared in stachyose very early in the time sequence, tending to confirm the hypothesis.
