Other claims from this paper (9)

Intervention effect Freezing at stem elongation changed grain morphology and yield characters.
Intervention effect In most cultivars, grain length-width ratio, roundness and sterile spikelets increased under low temperature.
Intervention effect In most cultivars, grain equivalent diameter, grain area and 1000-grain weight decreased.
Intervention effect In most cultivars, grain yield decreased.
Association After stem-elongation freezing, leaf SOD activity and soluble sugar content were dominant factors affecting grain yield, especially SOD activity.
Observation Nine named cultivars belonged to the high freeze-resistance group.
Observation Linmai 2, Weimai 8, Yannong 19 and Zimai 12 belonged to the low freeze-resistance group.
Observation Seven other cultivars had medium freeze resistance.
Recommendation The authors identify seedling stage as critical for selecting wheat freeze resistance.
