Abstract

This study mainly focuses on the proportion and distribution of various nutrient components in shoots, grains, and flowers of the landrace variety of common and tartary buckwheat grown by local farmers in Chamba district of Himachal Pradesh. Among all the samples analyzed, tartary buckwheat grains and common buckwheat grains showed the highest carbohydrate content i.e., 50.81 % and 44.66 %, respectively. In both species lowest carbohydrate content was observed in the flower portion (16–21 %). The highest crude fiber percentage was detected in common buckwheat shoot (41.2 %). The highest protein content was reported in tartary buckwheat shoot (37.99 %), while the lowest protein content was observed in grains of common buckwheat (20.99 %). Common buckwheat showed a slightly higher fat percentage than tartary buckwheat. Oleic acid (OA), linoleic acid (LA), and palmitic acid (PA) are the dominant fatty acids reported from both species. OA (C18:1) and LA (C18:2) are found in the highest amount in grain oil of both tartary and common buckwheat. While in case of shoot oil, PA is the main constituent followed by gondoic acid and LA in common and tartary buckwheat, respectively. Flower oil showed lower content of LA (24.31 %) in case of common buckwheat than tartary buckwheat flower oil (38.65 %). All the studied elements showed variable distribution in different parts of the plant samples. P, S, Na, Fe, and Cu are reported in the highest amount in tartary buckwheat shoots and K is found in maximum concentration (40.40 g/Kg) in common buckwheat grains. The highest level of Ca and Mn was detected in common buckwheat shoot, while that of Zn in tartary buckwheat flowers (90.15 mg/Kg). This study revealed the distribution of various nutrient components in different parts of the landrace variety of buckwheat. This can be implicated in crop breeding programs for the selection of elite landraces and functional food development

喜马偕尔邦昌巴地区普通荞麦和苦荞地方品种籽粒、茎和花营养成分的分布

本研究主要研究喜马恰尔邦昌巴地区当地农民种植的普通荞麦和苦荞地方品种的芽、粒和花中各种营养成分的比例和分布。在所有样品中，苦荞和普通荞麦的碳水化合物含量最高，分别为50.81%和44.66%。在这两个物种中，花部分的碳水化合物含量最低（16 - 21%）。粗纤维含量最高的是普通荞麦芽（41.2%）。其中，苦荞茎部蛋白质含量最高（37.99%），普通荞麦籽粒蛋白质含量最低（20.99%）。普通荞麦的脂肪含量略高于苦荞。油酸（OA）、亚油酸（LA）和棕榈酸（PA）是这两个物种的主要脂肪酸。OA （C18:1）和LA （C18:2）在苦荞和普通荞麦的籽油中含量最高。茎部油的主要成分为PA，其次为贡豆酸，苦荞油的主要成分为LA。普通荞麦花油的LA含量（24.31%）低于苦荞花油（38.65%）。所有研究元素在植物样品不同部位的分布都是可变的。磷、硫、钠、铁和铜在苦荞芽中含量最高，钾在普通荞麦籽粒中含量最高（40.40 g/Kg）。普通荞麦茎部钙、锰含量最高，苦荞花中锌含量最高（90.15 mg/Kg）。本研究揭示了地方品种荞麦不同部位各种营养成分的分布。这可能涉及到作物育种计划，以选择优秀的地方品种和功能性食品开发
