Abstract

The importance of Nigella sativa plant is increasing day by day in many medical and nutritional fields, and the demand for it is increasing in foreign markets. Therefore, we chose the nigella plant to study the effect of spraying with a natural growth stimulant (Ascobein) at concentrations of zero, 50, 100 and 150 ppm on the productivity of seed and oil, as well as its effect on the activity of antioxidants. The results showed that the concentration of 100 ppm gave the highest values of vegetative growth traits; (Plant height (86.3 and 89.5cm), Number of branches (21.7 and 25.1), Fresh and Dry weight per plant (118.43 and 143.85gm, 23.86 and 28.29gm/plant) respectively for both seasons. Also, results revealed that foliar application of 100 ppm (Ascobein) improved the seed yield/plant (16.95 and 19.74gm), Oil % (45.73 and 48.02%), DPPH% (99.04 and 102.39%), TPC (447.17 and 450.54 mg GAE/g) and TFC (110.19 and 114.43 mg QE/g) for both seasons 20/2021 and 21/2022. The percentage of major fatty acids in nigella seeds oil has been estimated (Linoleic, Oleic, Palmitic and Stearic).

天然生长刺激物(Ascobein)对黑草种子和油脂生长及产量的影响

黑草在许多医疗和营养领域的重要性日益提高，国外市场对黑草的需求量也在不断增加。因此，我们选择黑草植物，研究了在0、50、100和150 ppm浓度下喷洒天然生长刺激剂(Ascobein)对黑草种子和油脂产量的影响，以及对抗氧化剂活性的影响。结果表明:100 ppm的浓度对营养生长性状的影响最大;(株高86.3 cm和89.5cm)，枝数21.7 cm和25.1 cm，单株鲜重和干重分别为118.43 gm和143.85gm, 23.86 gm和28.29gm/株)。在20/2021和21/2022两季，叶面施用100 ppm (Ascobein)可提高单株种子产量(16.95和19.74gm)、油%(45.73和48.02%)、DPPH%(99.04和102.39%)、TPC(447.17和450.54 mg GAE/g)和TFC(110.19和114.43 mg QE/g)。估计了黑油籽油中主要脂肪酸的百分比(亚油酸、油酸、棕榈酸和硬脂酸)。
