摘要
气候变化显著影响谷物的品质特性,积温、昼夜温差、降雨量、气体浓度比例等气候因子均不同程度影响谷物的生长环境,导致植物体内的生理生化代谢途径发生改变,进而改变植物体的性状,对谷物品质产生一系列影响。该文总结了不同气候因子对谷物的外观品质、蒸煮品质、营养品质、食味品质影响的研究进展,多种研究表明气候因子对谷物的颜色光泽、粒径大小、谷粒完整度、谷物蒸煮过程中的吸水率、膨胀率、碘蓝值、固形物含量、籽粒形态微观变化、谷物中挥发性成分、谷物中蛋白质、脂肪、淀粉、微量营养元素等均产生不同程度的影响。各种气候因子对谷物品质的影响存在单一或复合作用,但多种气候因子的复合互作关联作用调节机制还有待进一步研究。
Climate change significantly affects the quality characteristics of cereals.Climate factors such as accumulated temperature,daily temperature difference,rainfall and gas concentration and ratio affect the growing environment of cereals to varying degrees,leading to the changes of physiological and biochemical metabolic pathways of plants,and changes the traits of plants,which could have a series of effects on the quality of cereals.This paper summarized the research progress of different climatic factors affecting on the appearance quality,cooking quality,nutritional quality and eating quality of cereals.Many studies showed that climate factors had different effects on the color luster,particle size,grain integrity,water absorption,swelling rate,iodine blue value,solid content,microscopic changes of grain morphology,volatile components,protein,fat,starch and trace nutrients in grains.There are single and compound effects of various climatic factors on the quality of cereals,but the regulation mechanism of the compound interaction of various climatic factors still needs to be further studied.
