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)”
e5“Longer roots under MP, which were 15.4% and 10.6% higher than that under NP and HP respectively”
e1“As a pivotal wheat production base, the North China Plain”

- Intervention effect Melatonin priming increased spike number by 4.1% compared with hydropriming.
- Intervention effect Under one spring irrigation (W1) spike number was 13.7% higher than without spring irrigation (W0).
- Intervention effect Under jointing-stage irrigation (W1) yield was 23.0% higher than without spring irrigation (W0).
- Intervention effect Under jointing-stage irrigation (W1) 1000-grain weight was significantly reduced by 4.9% compared with no spring irrigation (W0).

- Intervention effect Melatonin priming increased tillering number by 4.0% compared with hydropriming.
- Intervention effect Melatonin priming increased dry matter accumulation by 13.9% compared with no priming.
- Intervention effect Melatonin priming increased dry matter accumulation by 6.6% compared with hydropriming.
- Intervention effect Roots under melatonin priming were 15.4% longer than without priming.
- Mechanism Longer roots under melatonin priming enhanced later soil water absorption in the deeper soil layer.
- 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.
