Fresh weight and number of shoots of grapevine in vitro shoots in −S and +S growing conditions

	Fresh weight (g)		Number of shoots
Weeks	+S	−S	+S	−S
0	0.12b	0.12b	1b	1b
2	0.19a ± 0.02	0.09b ± 0.03	1.75a ± 0.49	1.03b ± 0.16

In vitro shoots were grown for 2 weeks in medium with (+S) and without (−S) sulphur. Each value is the mean of the FW of ten in vitro shoots ±SD. Different letters indicate significant differences at p < 0.05.
