You are very welcome. I am not sure how one would determine if there was excessive fructans. I suppose the test would be whether there was any fructans remaining in the flower after it expanded. My guess, pure speculation, is that excess fructans would be of no value to the flower but might be turned to sucrose and exported for use in other parts of the developing scape.

During the nightly period of respiration, are bloom cell contents reclaimed by the plant, then drawn up the stem by the sun into other buds?

The material removed from the dying flower parts would be moved to developing parts of the scape (and also possibly other parts of the daylily) both during the day and the night. Respiration occurs both during the day and the night.

What triggers the bud to finally open? The ripening or maturation process appears to have both a physical and a chemical feedback loop.

Sorry, not something that I am familiar with.
