Table 2. Nectar samples with yeasts and nectar samples without yeasts.

Comparisons of average (±SD) concentrations of the three nectar sugars between nectar samples containing yeast cells and nectar samples without cells. t-tests and statistical significance are shown for each sugar.

Nectar sugars	Nectar samples (g of solute per 100 mL solution)		t	d.f	p
	With yeasts	Without yeasts
Sucrose	6.3 ± 7.8	10.6 ± 11.1	4.48	215	<0.0001
Glucose	2.5 ± 3.2	5.5 ± 3.8	7.95	196	<0.0001
Fructose	2.9 ± 2.9	5.6 ± 3.5	8.81	172	<0.0001
