摘要:
为了探究激动素对小麦籽粒产量和品质的影响,以中筋小麦品种济麦22为材料,研究了小麦拔节期、扬花期和花后10 d,3次叶面喷施不同浓度(10 mg/L、25 mg/L、50 mg/L)激动素对小麦品质的影响。结果表明,激动素处理显著增加了小麦穗粒数、千粒质量,进而显著提高籽粒产量,但对小麦籽粒淀粉含量及其组分没有明显影响; 提高了籽粒中清蛋白、谷蛋白及总蛋白质的含量,增加籽粒中K、Ca、P、Fe和Zn矿质元素的含量,降低小麦降落值,提高了小麦出粉率、面团揉混峰值高度和宽度,从而增加面团强度和延展性。
Abstract:
To study the effect of kinetin(KT)on yield and quality of wheat, wheat cultivar(Triticum aestivum L. Jimai 22)was used in this study to investigate the influence on wheat grain quality of foliar application different concentrations of KT at three growth stages(heading, flowering and ten days after flowering). The experiment results are as follows: kernels per ear(KPE)and grain yield were increased, however, total starch and its component contents did not obviously affect by KT treatments; KT increased albumin, glutelin and total protein levels, thereby improving nutrition and process quality of grain protein. KT treatment increased K, Ca, P, Fe and Zn contents of wheat grain, increased flour yield and decreased falling number, and increased dough mixing peak height and width and thus increased dough strength and extensibility.
