In 1.6.2 and earlier fully grown wheat/carrots/potatoes would pop-off into item form when the light level in the block was reduced to 0. Since snapshot 13w36a wheat no longer does this, this includes the current 1.7.2 release.
The screenshots show the results of placing a block above the water, reducing the light level of the wheat to 0. In 1.6.2 the wheat pops off, in the snapshot the wheat remains.
Creative or survival.

Despite being marked as duplicate, and the duplicate being marked as resolved, the behaviour described here remains the same, and has not changed since first reported. Wheat does not pop-off in light level 0. This bug remains in all snapshots up to and including 14w08a.
...I will reopen this, but will ask a dev to close this as WAI
This, in my opinion, in or should be marked as Intended because this could make for some very unintended behavior: Wheat popping off at light level 0.
Compare to real life: If you encase wheat, would it pop off imedieatly?
To narrow it down, this behavior started being observable in "snapshot 1.7". I tested each official and development version available in the official launcher from 14w18b down to 1.5.2. The behavior does not occur in 1.6.4 or earlier. In those, crops uproot in light 7 or less.
Was an unintended side effect of removing the light-level check from the "Bush" block type, from which crop blocks inherit. Fixed by adding the original light-level check as an override in the crop block type.
Maybe the fix of this ticket is causing since 14w21b the uprooting of seeds at night below trees, see MC-56041
While this bug to this point only mentions crops, I note that flowers, saplings, and pumpkin/melon stems showed the same behavior change between 1.6.4 and 1.7. I don't know if you'd prefer that to be part of this bug, or a new bug, or if those others are working as intended in not popping off.
