Overview

Explores how low-temperature stress affects yield formation in winter wheat cultivars, suggesting structural adaptations as critical indicators.

Key Points

  • The aim is to understand how low-temperature stress during the jointing stage alters the source-flow-sink system in winter wheat.
  • Selected three wheat cultivars with different winter habits.
  • Subjected them to six temperature levels from -6 °C to 8 °C.
  • Analyzed vascular bundle traits and their impact on photosynthesis, dry matter, and yield.
  • Zhenmai 12 and Jimai 22 ceased photosynthesis at 0 °C and -3 °C, respectively.
  • Leaf vascular bundle area decreased with increased low-temperature stress.
  • Dry matter in leaves decreased by 15-20%, while root dry matter increased by 20-30%.
