Low temperature (LT) during the booting stage of winter wheat can reduce yield, prompting a study using two wheat cultivars: LT-sensitive 'Wanmai 52' and LT-insensitive 'Yannong 19'.
The research involved applying LT treatments (-2°C and 0°C) followed by spraying different concentrations of a growth hormone, 6-benzylaminoadenine (6-BA), to observe its effects on wheat growth and yield.
Results revealed that 6-BA application improved floret development, enhanced physiological traits like sugar and protein accumulation, and ultimately led to a better yield, with the most effective concentration being 20 mg·L for the LT-insensitive cultivar.
