Within a column，means followed by the same letters are not significantly different by the LSD test at P≤0.05 under completely randomized design.Z0:control；Z100:100 mg/L ZJ0273；aa10:10 mg/LBCAAs（valine，leucine，isoleucine）；aa50:50 mg/L BCAAs；aa100:100

A significant reduction in shoot length，fresh and dry weights was recorded in barley seedlings in response to 100 mg/L of ZJ0273（Table 5）.Plants treated with 100 mg/L ZJ0273 alone experienced maximum damage in this hydroponic study，showing reductions of 31.3%in shoot length，30.2%in fresh weight，and 25.0%in dry weight，compared with controls.Exogenously applied BCAAs（10–200 mg/L）in the nutrient solution significantly increased the growth of barley seedlings in terms of shoot length and fresh and dry weights.Application of BCAAs to herbicidefree media also promoted growth of barley seedlings，but the effect on shoot length or dry weight was not significant compared with the control（non-BCAA，nonZJ0237 treated）.Maximum growth（shoot length，fresh and dry weights）of herbicide-stressed seedlings was observed with 200 mg/L of BCAAs.Plants treated with 200 mg/L BCAAs alone showed no significant change in growth.BCAAs significantly promoted barley growth when applied to ZJ0273（100 mg/L）-stressed plants，causing increases of 37.0%in shoot length，38.1%in fresh weight，and 33.9%in dry weight，compared with the 100 mg/L ZJ0273 treatment alone.The fresh and dry weights of the plants remained unaffected when treated with 100 mg/L ZJ0273+200 mg/L BCAAs.No significant changes occurred in the shoot growth of stressed seedlings with 100 or 200 mg/L of BCAAs，suggesting that100 mg/L of BCAAs could be the best concentration for protecting barley seedlings from herbicide stress.Thus，we selected this concentration for the subsequent physiology experiments.
