玉米籽粒形态、结构特征与耐破碎性的关系研究
Relationship Between Morphological and Structural Characteristics of Corn Kernel and Its Breakage Resistance
摘要
Abstract
This study aimed to reveal the influence of the morphology and internal structure of corn kernel on its breakage resistance,providing a theoretical basis for the selection and breeding of corn cultivars suitable for mechanical grain harvesting.'DH618','DK159'and'HM1'were selected as tested cultivars,the morphological and structural parameters of kernel were obtained by CT scanning while kernel breaking force was measured by static compression test.The kernel of'DH618'was the largest in length(6.85-14.03 mm),thickness(4.22-7.64 mm)and volume(74.16-313.79 mm3),the proportion of its embryos in kernel was also the highest(10.49%-11.26%).The kernel of HM1 had the largest grain width(5.71-8.75 mm)and the highest subcutaneous cavity ratio(1.26%-2.05%).The relationship between the morphology,structure of corn kernel and its mechanical properties was identified,which would provide an essential reference for the study of corn kernel's characters and conduce to the selection and breeding of corn cultivars favoring mechanical grain harvesting.关键词
