Effect of 24-epibrassinolide on salinity-induced changes in loquat (Eriobotrya japonica Lindl)
This study was carried out to investigate the role of 24-epibrassinolide (24-EBL) in inducing loquat plant salt tolerance. Plants were treated with five levels of salt, so that the electrical conductivity (EC) of 0.5 (control), 2, 4, 6 and 8 dS m-1 was established in pots. Then, the plants were spr...

Then, the plants were sprayed with different concentrations of 24-EBL (0, 0.25, 0.5 and 0.75 mg l-1).
