Evaluating the effect of Brasinolide on the salinity tolerance of spring onion (Allium fistulosum L.) under saline irrigation conditions
Main Article Content
Abstract
Spring onions are an essential spice in Vietnamese food preparation for its favor and aroma. Tra Vinh, one of the coastal provinces, is greatly affected by climate change and saline intrusion. Hence, this study was conducted to access the effects of Brasinoline (Br) on the growth of Spring onion under normal conditions and salt stress events. The experiment embraced four Br concentrations (0 ppm, 0.05 ppm, 0.1 ppm, and 0.15 ppm) under both fresh water and 3‰ saltwater irrigation conditions, distributed according to the 2-factor Randomized Completely Block Design (RCBD). Preliminary results, with concentrations of Br 0.1 ppm and 0.15 ppm, show a high increase in leaf length, number of leaves/brush, number of shoots, stem diaphragm and plant green weight. Under 3‰ salt water irrigation conditions, Br concentration of 0.15 ppm showed supporting effectively the growth of Spring onions equivalent to that in fresh water.
