From: Foliar application of 24-epibrassinolide enhances leaf nicotine content under low temperature conditions during the mature stage of flue-cured tobacco by regulating cold stress tolerance

Fig. 4

Foliar application of different EBR compounds significantly represses the expression of senescence-promoting genes (NtCP1 and NtCP23) and promotes the expression of senescence-repressing genes (NtPSA1 and NtMC) during the development of upper leaves. CK2, B1, B2 and B3 indicate as shown in Fig. 2. 10 d, 20 d, 30 d, 40 d and 50 d indicate as shown in Fig. 2. The data presented are the mean ± SD. Different letters indicate significant differences among the treatments based on Duncan’s test (P < 0.05)
