To investigate the effects of spermidine on the starch composition and gelatinization characteristics of wheat grains, using the wheat varieties Xinong 538 and Lankaoaizao 8 as experimental materials, four spermidine spray concentrations (0.25, 0.75 and 1 mmol·L-1) were set up at grain-filling stage. The indicators of starch composition, granule size distribution, and gelatinization characteristics of wheat grains were determined and analyzed. The results showed that compared with spraying clear water CK, spraying 0.25 and 0.75 mmol·L-1 spermidine significantly increased the 1 000-grain weight and yield of the two varieties. After the application of spermidine, the amylose content of Xinong 538 and Lankaoaizao 8 decreased and increased, respectively. The amylopectin ratio showed a decreasing trend and a downward increase followed by a decrease with the increase of the application concentration. Overall, spermidine spraying reduced the quantity and volume of A type starch granules in both varieties and increased the quantity and volume of B type starch granules. High concentration (1 mmol·L-1) of spermidine reduced, increased and decreased the peak viscosity, final viscosity, and breakdown of Xinong 538 and Lankaoaizao 8, respectively. 0.75 mmol·L-1 spermidine increased the peak viscosity, trough viscosity, breakdown, final viscosity, and setback of Lankaoaizao 8, while increased the breakdown, setback, peak time, and pasting temperature of Xinong 538. Overall, under the conditions of this experiment, the application of 0.75 mmol·L-1 arginine spray significantly increased the 1 000-grain weight and yield of wheat, and by influencing the amylose content, amylose/amylopectin ratio and type B starch particle composition of wheat, increased the peak viscosity and breakdown of wheat grain starch, thereby enhancing the gelatinization characteristics of wheat and ultimately improving the quality of wheat starch. It is a relatively suitable spraying concentration in wheat production.

为探讨亚精胺对小麦籽粒淀粉组成及糊化特性的影响,以小麦品种西农538和兰考矮早8为试验材料,在灌浆期喷施0.25、0.75和1.00 mmol·L-1浓度亚精胺,测定和分析了小麦籽粒淀粉组成、粒度分布、糊化特性等指标。结果表明,与喷施清水对照相比,喷施0.25和0.75 mmol·L-1亚精胺显著提高了两个品种的千粒重和产量。喷施亚精胺后西农538和兰考矮早8的直链淀粉含量分别降低和提高,淀粉直支比随喷施浓度的提高则分别表现为下降和先升后降的趋势。总体上,喷施亚精胺减少了两个品种的A型淀粉粒数量和体积,增加了B型淀粉粒数量和体积。高浓度(1 mmol·L-1)亚精胺对西农538的峰值黏度、最终黏度、衰减值均产生负效应,但提升了兰考矮早8的这3个指标。而0.75 mmol·L-1亚精胺提高了兰考矮早8峰值粘度、最低黏度、衰减值、最终黏度和回升值,增加了西农538衰减值、回升值、峰值时间和糊化温度。综合来看,在本试验条件下,喷施0.75 mmol·L-1亚精胺显著提升小麦千粒重及产量,并通过影响小麦直链淀粉含量、直/支比和B型淀粉粒组成,提高小麦籽粒淀粉的峰值黏度和衰减值,从而提升小麦的糊化特性,最终改善小麦淀粉品质,在小麦生产上是比较适宜的喷施浓度。

为探讨亚精胺对小麦籽粒淀粉组成及糊化特性的影响,以小麦品种西农538和兰考矮早8为试验材料,在灌浆期喷施0.25、0.75和1.00 mmol·L-1浓度亚精胺,测定和分析了小麦籽粒淀粉组成、粒度分布、糊化特性等指标。结果表明,与喷施清水对照相比,喷施0.25和0.75 mmol·L-1亚精胺显著提高了两个品种的千粒重和产量。喷施亚精胺后西农538和兰考矮早8的直链淀粉含量分别降低和提高,淀粉直支比随喷施浓度的提高则分别表现为下降和先升后降的趋势。总体上,喷施亚精胺减少了两个品种的A型淀粉粒数量和体积,增加了B型淀粉粒数量和体积。高浓度(1 mmol·L-1)亚精胺对西农538的峰值黏度、最终黏度、衰减值均产生负效应,但提升了兰考矮早8的这3个指标。而0.75 mmol·L-1亚精胺提高了兰考矮早8峰值粘度、最低黏度、衰减值、最终黏度和回升值,增加了西农538衰减值、回升值、峰值时间和糊化温度。综合来看,在本试验条件下,喷施0.75 mmol·L-1亚精胺显著提升小麦千粒重及产量,并通过影响小麦直链淀粉含量、直/支比和B型淀粉粒组成,提高小麦籽粒淀粉的峰值黏度和衰减值,从而提升小麦的糊化特性,最终改善小麦淀粉品质,在小麦生产上是比较适宜的喷施浓度。

To investigate the effects of spermidine on the starch composition and gelatinization characteristics of wheat grains, using the wheat varieties Xinong 538 and Lankaoaizao 8 as experimental materials, four spermidine spray concentrations (0.25, 0.75 and 1 mmol·L-1) were set up at grain-filling stage. The indicators of starch composition, granule size distribution, and gelatinization characteristics of wheat grains were determined and analyzed. The results showed that compared with spraying clear water CK, spraying 0.25 and 0.75 mmol·L-1 spermidine significantly increased the 1 000-grain weight and yield of the two varieties. After the application of spermidine, the amylose content of Xinong 538 and Lankaoaizao 8 decreased and increased, respectively. The amylopectin ratio showed a decreasing trend and a downward increase followed by a decrease with the increase of the application concentration. Overall, spermidine spraying reduced the quantity and volume of A type starch granules in both varieties and increased the quantity and volume of B type starch granules. High concentration (1 mmol·L-1) of spermidine reduced, increased and decreased the peak viscosity, final viscosity, and breakdown of Xinong 538 and Lankaoaizao 8, respectively. 0.75 mmol·L-1 spermidine increased the peak viscosity, trough viscosity, breakdown, final viscosity, and setback of Lankaoaizao 8, while increased the breakdown, setback, peak time, and pasting temperature of Xinong 538. Overall, under the conditions of this experiment, the application of 0.75 mmol·L-1 arginine spray significantly increased the 1 000-grain weight and yield of wheat, and by influencing the amylose content, amylose/amylopectin ratio and type B starch particle composition of wheat, increased the peak viscosity and breakdown of wheat grain starch, thereby enhancing the gelatinization characteristics of wheat and ultimately improving the quality of wheat starch. It is a relatively suitable spraying concentration in wheat production.
