Effect of 2 d of 0.174 mm sulfide on numbers of emergent laterals and lateral root growth 18 d after treatment

	Sulfide	Post-sulfide*	Control
No. of emergent laterals per cm length of root†	2·98 ± 0·64a	33·53 ± 2·3b	32 ± 1·5b
Length of laterals (mm)†	0·35 ± 0·24x	3·44 ± 0·45y	3·9 ± 0·31y

Means ± s.d., n = 12.

Treatment time was 2 d.

^*New adventitious roots produced post-sulfide.

^†Laterals produced post-treatment period.

Significant differences (Tukey test: P < 0·05) between treatments are indicated by letters.
