Abstract

A b s t r a c t. The nutrient content and the morphological and anatomical features of kernels were compared for 11 breeding lines of tritordeum and three Triticum durum cultivars. The kernel shape descriptors were examined using digital image analysis, and the contents of four basic nutrients were determined. Tritordeum grain had a significantly higher content of protein, fat, ash and fibre than durum wheat grain. In turn, the values of one kernel weight, kernel thickness and hardness were significantly lower in tritordeum. Tritordeum kernels are elongated, relatively small, with a deep crease and a small cross-sectional area. All lines differed considerably with regard to the examined phenotypic attributes. Tritordeum lines and the reference cultivars were most effectively distinguished based on fibre content, spike length, spikelet number per spike, and kernel number and weight per spike.

小麦——谷物中基本营养物质的含量以及籽粒的形态和解剖特征

**本工作由教育部和科技部资助，项目编号:010/ RID/2018/19，资助金额为1200万兹罗提(兹罗提)。比较了11个小麦品种和3个硬粒小麦品种的营养成分含量和籽粒形态解剖特征。利用数字图像分析对籽粒形状描述符进行了检测，并测定了4种基本营养素的含量。小麦籽粒的蛋白质、脂肪、灰分和纤维含量均显著高于硬粒。单粒重、粒厚和硬度在三氮唑下均显著降低。三棱核呈细长状，相对较小，折痕深，横截面积小。所有品系在表型性状方面差异很大。以纤维含量、穗长、每穗小穗数、每穗粒数和每穗粒重为指标，对三合秆系和对照品种进行了最有效的区分。单粒重、全粒面积、折痕深度和折痕底部到籽粒边缘的距离是最不显著的性状。结果表明，在中欧地区，三粒小麦比硬粒小麦多积累19%以上的蛋白质和43%以上的纤维。经检验的三刚体品系虽然产量潜力比现代硬粒葡萄品种低两倍，但前景非常光明。介绍:三体，基本营养成分，截面，颗粒，形状分析

期刊介绍： The journal is focused on the soil-plant-atmosphere system. The journal publishes original research and review papers on any subject regarding soil, plant and atmosphere and the interface in between. Manuscripts on postharvest processing and quality of crops are also welcomed. Particularly the journal is focused on the following areas: implications of agricultural land use, soil management and climate change on production of biomass and renewable energy, soil structure, cycling of carbon, water, heat and nutrients, biota, greenhouse gases and environment, soil-plant-atmosphere continuum and ways of its regulation to increase efficiency of water, energy and chemicals in agriculture, postharvest management and processing of agricultural and horticultural products in relation to food quality and safety, mathematical modeling of physical processes affecting environment quality, plant production and postharvest processing, advances in sensors and communication devices to measure and collect information about physical conditions in agricultural and natural environments. Papers accepted in the International Agrophysics should reveal substantial novelty and include thoughtful physical, biological and chemical interpretation and accurate description of the methods used. All manuscripts are initially checked on topic suitability and linguistic quality.
