Sugar Variation in Soybean Seed Assessed with a Rapid Extraction and Quantification Method

Table 3

Means of individual sugars in 20 soybean genotypes over replications of two duplicate extractions.

Sugar	Average sugar content (mg/g)^(a)
	Extraction I		Extraction II
	Replication 1	Replication 2	Replication 1	Replication 2
Glucose	0.18	0.17	0.13	0.12
Fructose	0.12	0.12	0.11	0.05
Sucrose	4.49	4.47	4.82	4.68
Raffinose	0.86	0.91	0.91	0.96
Stachyose	3.41	3.42	3.45	3.45
Total sugar	9.05	9.09	9.35	9.12

^(a)Two duplicate extractions following Giannoccaro et al. [16] were prepared from each sample, and each extraction was analyzed in two replicates.
