Consumption of whole-wheat based products is encouraged due to their important nutritional elements that benefit human health. However, the use of whole-wheat flour is limited because of the poor processing and end-product quality. Bran was postulated as the major problem in whole wheat breadmaking. In this study, four major bran components including lipids, extractable phenolics (EP), hydrolysable phenolics (HP), and fiber were evaluated for their specific functionality in flour, dough and bread baking. The experiment was done by reconstitution approach using the 24 factorial experimental layout. Fiber was identified as a main component to have highly significant (P < 0.05) and negative influence on most breadmaking characteristics. Although HP had positive effect on farinograph stability, it was identified as another main factor that negatively impacted the oven spring and bread loaf volume. Bran oil and EP seemed to be detrimental to most breadmaking characteristics. Overall, statistical analysis indicates that influence of the four bran components are highly complex. The bran components demonstrate multi-way interactions in regards to their influence on dough and bread-making characteristics. Particularly, Fiber appeared to have a high degree of interaction with other bran components and notably influenced the functionality of those components in whole wheat bread-making. 相似文献

在盆栽条件下,研究了啤酒糟和白酒糟对连作平邑甜茶幼苗生长及其连作土壤中微生物的影响。结果表明,连作土壤添加酒糟可显著提高平邑甜茶幼苗株高、干样质量、鲜样质量等生物量指标。添加酒糟后土壤中细菌、真菌数量与连作土对照相比也有明显提升。通过聚类分析、主成成分分析和多样性分析发现,加入酒糟后土壤中微生物群落结构发生明显变化,且不同酒糟类型和不同酒糟处理方式造成微生物的群落结构不同;由于酒糟自身携带及灭菌酒糟在土壤中滋生的微生物,促使土壤中优势种群的出现,改变了土壤中微生物群落的多样性指数和丰富度指数。对土壤中的层出镰孢菌(Fusarium proliferatum)进行实时荧光定量分析显示,与连作土壤对照中的层出镰孢菌基因拷贝数相比,啤酒糟、白酒糟、灭菌啤酒糟和灭菌白酒糟处理分别降低了39.1%、58.1%、20.9%和39.2%,酒糟灭菌后减弱了对有害菌层出镰孢菌的抑制作用。综上,苹果连作土壤中加入酒糟后,改变了土壤中微生物的群落结构,降低了有害真菌的数量,减轻了苹果连作障碍现象,其中白酒糟效果更好。 相似文献

滇型杂交粳稻的研究与开发在云南高原已有30多年的历史,为云南水稻增产作出了巨大贡献。然而,我们对滇型杂交水稻在旱作条件下的表型特征特性却知之甚少。本研究的主要目的在于鉴定育成滇型杂交稻组合的耐旱特征特性,并对生长速率,其他表型性状与经济产量的相关关系进行研究,以期为滇型杂交稻旱作节水栽培和今后的耐旱育种提供理论依据。试验结果表明,滇型杂交粳稻品种(组合)耐旱性有显著的遗传差异,其中滇杂35产量和结实率均明显高于其它4个参试品种(组合)。小区产量与每穗实粒数和减数分裂期的生长速率相关系数分别为0.96和0.93,达极显著水平,与结实率的相关系数达0.9,为显著水平,表明在以小区产量为目标的育种项目中,使用这些性状可以大大地提高育种效率。 相似文献

寒地水稻品种子粒灌浆特性差异及其对结实率的影响 总被引:3,自引:0,他引:3
用 L ogistic生长方程 W =K/ (1+ ae-bt)对寒地水稻品种 (系 )强、弱势子粒灌浆过程进行了分析 ,并依配得的 L ogistic方程导出了若干个子粒灌浆特性参数。结果表明 ,强势粒的起始灌浆量、最大灌浆强度高于弱势粒 ,有效灌浆期比弱势粒短 ,最大灌浆速率出现时间和最大灌浆速率期早于弱势粒。强、弱势粒各项灌浆参数均存在品种间差异。相关分析表明 ,强势粒和弱势粒的最大灌浆速率出现时间早、最大灌浆速率期早、平均灌浆强度高 ,弱势粒起始灌浆量大、最大灌浆速率高 ,强弱势粒同步灌浆性强 ;结实率高 ,寒地超高产水稻品种应适当提早抽穗期 ,从而提早弱势粒最大灌浆速率期 ,保证较高结实率水平 相似文献

A study was done on the relationship between Aphelenchoides besseyi and the symptoms of small grains and erect panicles. This is an important rice disease in Jiangsu Province, China. A. besseyi was extracted from small grains and erect panicles and cultured artificially, and then inoculated into bud and leaf sheaths of seedlings of two Oryza sativa cultivars, namely Zhendao 2 and Wuyunjing 7 in a greenhouse. The effect on rice growth, in particular the small grains and erect panicles, was revealed by the extent of the disease, seed expansion stages, nematode load, and nematode mortality. In contrast to healthy seedlings, the height, length, and the numbers of spikelets of unhealthy panicles of Zhendao 2 were decreased by 6.7, 16.4, and 13.5%, respectively. Before anthesis, nematodes were attracted to the leaf sheath and apical meristem, nematode load increased by 40%; after anthesis, nematodes occurred in spikelets principally and the number increased by 90.8%. The percentages of infected seeds and nematode load were highest in plump seeds and lowest in empty seeds. Nematode mortality on grain with normal endosperm was lower than seeds with abnormal endosperm. Results indicated that A. besseyi was the pathogen in rice with the symptoms of small grains and erect panicles. Wuyunjing 7 manifests only the small grains and erect panicles symptoms and not the symptoms of leaf white-tip. These symptoms of small grains and erect panicles are new symptom records for the disease caused by A. besseyi on rice. 相似文献
