e0“on winter wheat compared W1 (jointing-stage irrigation) vs. W0 (no spring irrigation) as main plots, with subplots of NP (no priming), HP (hydropriming), and MP (melatonin priming)”
e3“Correspondingly, spike number and yield under W1 were higher by 13.7% and 23.0% than that under W0, whereas 1000-grain weight was significantly reduced by 4.9%”
e1“As a pivotal wheat production base, the North China Plain”

- Intervention effect Under water-limited conditions, water productivity of melatonin-primed wheat was 8.4% higher than with no priming.
- Mechanism Melatonin-primed winter wheat had enhanced seedling quality, which underlies the increase in spike number and 1000-grain weight.
