Yes: The amount of saliva is more during the day and is increased as we eate or think of eating. The pavloving reflex.

Yes: The biological significance of decreased saliva during sleep is unknown and it is unclear how the oral cavity compensates for this period of relative dryness. The amount of saliva produced is greatest during the waking hours of the day and diminishes dramatically during sleep and may represent another process in the human body that displays a circadian rhythmicity.
