Abstract

Climate variability is a major challenge concerning food security; therefore, there is a need for pragmatic solutions to improve agricultural production. Henceforth, this study was planned to optimize the planting time of exotic safflowers under the prevailing conditions in Faisalabad, Pakistan. A study was executed by employing a split-plot design with six safflower accessions and five sowing dates ranging from 31 October 2019 to 31 December 2019. The results of the experimental safflower accession PI-198990 produced significant seed yields (2432 kg ha−1, 2772 kg ha−1 and 2366 kg ha−1) when sown on 30 November 2019, 15 December 2019, and 31 December 2019, respectively. On the other hand, on 31 October 2019 and 30 November 2019, sown safflower accessions PI-208677 and PI-250187 were the best performers, respectively. However, a higher achene oil percentage (31.5% and 30.8%) was noted in accessions PI-250187 and PI-314650 when sown on 31 December 2019 and 15 December 2019, respectively. The highest oleic acid content (22.92% and 22.83%) was determined in accession PI-314650 when planted on 30 November 2019 and 15 December 2019, respectively, whereas a higher linoleic acid content was observed on 31 October 2019 and 30 November 2019. Stability analysis showed that safflower accession PI-210834 was the most stable under all sowing environments, followed by PI-314650. Correlation analysis showed that oil percentage showed a negative correlation with phenological traits and growing degree days, and oil yield showed a strong positive relationship with heads, seed yield, biological yield, thousand seed weight, and harvest index.

气候多变性如何影响红花（Carthamus tinctorius L.）产量、油脂和脂肪酸的播种日期

气候多变是粮食安全方面的一大挑战；因此，需要务实的解决方案来提高农业产量。因此，本研究计划在巴基斯坦费萨拉巴德的现有条件下优化外来红花的种植时间。研究采用分小区设计，有六个红花品种和五个播种日期，播种日期从 2019 年 10 月 31 日到 2019 年 12 月 31 日不等。实验红花品种 PI-198990 在 2019 年 11 月 30 日、2019 年 12 月 15 日和 2019 年 12 月 31 日播种，分别产生了显著的种子产量（2432 千克/公顷-1、2772 千克/公顷-1 和 2366 千克/公顷-1）。另一方面，在 2019 年 10 月 31 日和 2019 年 11 月 30 日播种的红花品种 PI-208677 和 PI-250187 分别表现最佳。然而，在 2019 年 12 月 31 日和 2019 年 12 月 15 日播种的品种 PI-250187 和 PI-314650 的瘦果油百分比较高（31.5% 和 30.8%）。分别在 2019 年 11 月 30 日和 2019 年 12 月 15 日播种的品种 PI-314650 的油酸含量最高（22.92% 和 22.83%），而在 2019 年 10 月 31 日和 2019 年 11 月 30 日播种的品种亚油酸含量较高。稳定性分析表明，在所有播种环境下，红花品种 PI-210834 的稳定性最好，其次是 PI-314650。相关性分析表明，出油率与物候性状和生长度日呈负相关，出油率与头数、种子产量、生物产量、种子千粒重和收获指数呈较强的正相关。
