24-Epibrassinolide-Succinic Acid Conjugate Is Involved in the Acclimation of Rape Plants to Salt Stress.

ABSTRACT: The influence of the conjugate of 24-epibrassinolide with succinic acid (tetrahydrosuccinate of 24-epibrassinolide, EBL THS) and 24-epibrassinolide (EBL) on the acclimation of rapeseed plants (Brassica napus L.) to chloride salinity (150 mM NaCl) was investigated. After two weeks of growth in Hoagland-Snyder medium, the rapeseed seedlings were transferred to the same medium supplemented with EBL or EBL THS (10 nM) for 4 h, after which NaCl (150 mM) was added; parameters were taken on the 1st, 3rd, 5th and 7th days. It was established that salt stress inhibited growth processes (by 19-45%), reduced the chlorophyll and carotenoid contents (by 19-50%), photosystem II efficiency (by 13-19%), tissue hydration (by 3.54%), and osmotic potential (by three times), increased lipid peroxidatio
