摘要
为了探明增香栽培对优质香稻品质和产量的影响,以4个优质常规香稻、4个优质杂交香稻品种为试验材料,以常规和增香两种栽培措施进行大田对比试验,测定各优质香稻的脯氨酸质量分数、品质、理论产量及产量构成因素.结果表明:与常规栽培相比,供试香稻的脯氨酸质量分数和整精米率、杂交香稻的蛋白质质量分数与胶稠度显著提高,杂交香稻的垩白度与垩白粒率以及供试香稻的直链淀粉质量分数显著降低;供试香稻的淀粉黏滞性RVA谱特征值整体呈下降趋势,下降程度不等,其中杂交香稻的起浆温度显著上升,而常规香稻的冷胶黏度、起浆温度以及峰值时间变化无统计学意义;常规香稻的食味值显著下降,而杂交香稻的食味值变化无统计学意义.除此之外,增香栽培对理论产量及产量构成有不同影响,其中杂交香稻的产量及有效穗数显著升高,穗粒数和千粒质量变化无统计学意义.
Abstract
To investigate the effect of aroma-enhancing cultivation on the quality and yield of high-quality aromatic rice,four high-quality conventional fragrant rice varieties and four high-quality hybrid aromatic rice varieties were used as experimental materials to conduct comparative field experiments with conven-tional and aroma-enhancing cultivation methods in this study.Each high-quality aromatic rice was meas-ured for proline content,grain quality,yield,and yield composition.Compared with conventional cultiva-tion,the proline content and head-milled rate of aromatic rice,and the protein content and gel consistency of hybrid aromatic rice were significantly increased.The degree of chalkiness and the rate of chalkiness grain of hybrid aromatic rice and the amylose content of the aromatic rice decreased significantly.The RVA spectrum characteristics of starch viscosity of fragrant rice showed an overall decreasing trend with different degrees of decline.The pasting temperature of hybrid aromatic rice increased significantly,while cool paste viscosity,pasting temperature,and peak time of conventional aromatic rice showed no signifi-cant changes.There was a significant decrease in the flavor score of conventional aromatic rice,but no sig-nificant change in the flavor score of hybrid aromatic rice.In addition,aroma-enhancing cultivation had different effects on yield and yield composition.Among them,the yield and effective panicles of hybrid ar-omatic rice significantly increased,while the number of grains per panicle and thousand grain weight did not show significant changes.
