Determination of the content of lignin in tobacco.

Plant	WT	4CL			CCoAOMT
		1	2	3	1	2	3
Average lignin content %	4.86	8.31	10.51	7.14	9.13	7.54	8.34
SD	0.983	1.457	2.819	0.404	2.318	0.507	1.365
Sig		<0.05	<0.01	<0.05	<0.01	<0.05	<0.01

For every tobacco genotype 3 plants were measured (n = 3), 3 technical repetitions were done per plant sample. SD, standard deviation from selected lines. Sig, the level of significance, data was compared through t-test.
