Wheat is the most widely grown crop globally and an essential source of calories in human diets. Maintaining and increasing global wheat production is therefore strongly linked to food security
Increased Cell-Wall Mass and Resistance to Freezing and Snow Mold during Cold Acclimation of Winter Wheat under Field Conditions
Carbohydrate accumulation Cell-wall mass Cold acclimation Freezing resistance Snow mold resistance
2009/7/23
Accumulation of soluble carbohydrates plays an important role in enhancement of resistance to freezing and snow mold of plants during cold acclimation. Nevertheless, few studies have examined whether ...
Factors in the Reduction in Grain Number in Winter Wheat by Early-Sowing in Yamaguchi
Early sowing cultivation Grain number per spike Grain number per spikelet Multiple regression Spike development period Spikelet number per spike Temperature Winter wheat cultivar
2009/7/23
Grain number per spike of wheat is lower in early sowing than in the conventional standard cultivation in Yamaguchi, Prefecture, Japan. Components of the grain number per spike in five cultivars were ...
Effects of Irrigation and Straw Mulching on Microclimate Characteristics and Water Use Efficiency of Winter Wheat in North China
Irrigation Microclimate Straw mulching Water use efficiency Winter wheat
2009/7/23
In North China, irrigation is required to obtain a high yield from winter wheat; this results in rapid aquifer depletion. The primary objective of this study was to investigate the influencing mechani...
Factors Causing -Amylase Activation and Low Falling Number in Winter Wheat Variety Kitanokaori
Amylograph viscosity α-Amylase activity Falling number Pre-harvest sprouting
2009/7/7
Amylograph viscosity, an important index of wheat quality, is sometimes lowered by high α-amylase activity in grain caused by pre-harvest sprouting. In a new winter wheat variety, Kitanokaori, the pe...
