TABLE 4.

Effects of BABA, Ca²⁺, BABA + Ca²⁺, and BABA + EGTA on IAA and ABA content of tobacco seedlings under cold stress.

Treatment	IAA (μg g–1 FW)	ABA (μg g–1 FW)
Cold	0.28 ± 0.03 e	0.91 ± 0.01 d
BABA	0.78 ± 0.02 c	1.30 ± 0.02 b
Ca2+	0.81 ± 0.01 b	1.29 ± 0.01 b
BABA + Ca2+	1.36 ± 0.01 a	1.62 ± 0.02 a
BABA + EGTA	0.46 ± 0.01 d	0.95 ± 0.01 c

The data are means ± SE, n = 3. Different letters in the same column contend a significant difference between treatments at P < 0.05.
