Effects of 2,4-D auxin on callus production for cvs Lorentii and Hahnii of Sansevieria trifasciata. (a) Callus induction, (b) fresh callus mass, (c) fresh mass gain index, (d) callus area, and (e) callus increase index were evaluated after 42 days of growth with different doses of 2,4-D. Values are means ± SD. Means with different letters are significantly different according to Tukey’s test (p ≤ 0.05).
