Fig. 1: EBR suppresses ethylene-induced fruit abscission and the expression of LcACS1/4 and LcACO2/3 in litchi.

a Ethylene production in fruitlets after ethylene (ET) or ethylene plus 2,4-epibrassinolide (ET + EBR) treatment. b Cumulative abscission rate of fruitlets after ET or ET + EBR treatment. c–f qRT-PCR analysis of LcACS1/4 and LcACO2/3 expression at the fruitlet abscission zone after ET or ET + EBR treatment. Letters indicate that the differences between the control and treatments were significant (p < 0.05).
