Abstract

The study was conducted at the Ishaqi palm plant affiliated with the Department of Horticulture/Ministry of Agriculture during the growing season of 2021 on date palm trees of the Khastawi variety to study the response of the yield traits of the Khastawi date palm trees to the injection of microelements, jasmonic and citric acid. The study included three factors: The first factor is the injection of microelements with three treatments: injection with water only, symbolized by D0, iron injection at a concentration of 300 mg, and iron sulfate. Palm1 , symbolized by D1, and boron injection through boric acid at a concentration of 40 mg Palm-1 , symbolized by D2. The second factor is the treatment of injections with the Jasmonic growth regulator, which was injected three days after the injection with the microelements and with the same number of additions (0, 50, 100) micrograms. L-1 is symbolized by G0, G1, and G2 sequentially. The trees were injected with the microelements and the Jasmonic growth regulator before Immunization, after vaccination in 20 days, and after 40 days. The third factor was injection with citric acid and included three levels (0, 500, 1000) mg l-1 symbolized by S0, S1, and S2 sequentially. The results showed that the D2 treatment was significantly superior in the average diameter, length, size and weight of the fruit and the total yield, as it reached 24.86 mm, 3.46 cm, 11.10 cm, 10.07 g, 36.00 kg.palm-1 sequentially, while the comparison treatment gave the lowest average for the traits. As for the effect of jasmonic acid, the injection treatment was superior to (100 µg L-1 ). (G2) gave the highest average for the diameter, length, size, weight of the fruit, and the total yield, which reached 25.90 mm, 3.63 cm, 12.09 cm, 10.93 g, and 35.96 kg. Palm-1, respectively, while the comparison treatment gave the lowest average for the traits above as for the effect of citric acid. The treatment exceeded 1000 mg.L-1 (S2) gave the highest rate in the diameter, length, size, and weight of the fruit, and the total yield, reaching 24.84 mm, 3.49 cm, 11.13 cm, 9.04 g, and 36.30 kg. Palm-1, respectively, while the comparison treatment gave the lowest average for the traits above, as the two- and three-interactions showed. The research factors have significant differences for all the studied traits. Keywords: Trace elements, jasmonic acid, citric acid, Khastawi variety.

注射微量元素、茉莉酸和柠檬酸对某些椰枣产量特征的影响

这项研究于 2021 年生长季节在农业部园艺司下属的伊沙奇棕榈种植园进行，对象是哈斯塔维（Khastawi）枣树，目的是研究哈斯塔维（Khastawi）枣树的产量性状对微量元素、茉莉酸和柠檬酸注射的反应：研究包括三个因素：第一个因素是微量元素的注射，有三种处理方法：仅用水注射（用 D0 表示）、注射 300 毫克浓度的铁和硫酸铁。以 D1 表示，通过硼酸注入浓度为 40 毫克（Palm-1）的硼，以 D2 表示。第二个因素是茉莉生长调节剂的注射处理，在注射微量元素三天后注射，添加量相同（0、50、100）微克。L-1依次用 G0、G1 和 G2 表示。苗木在免疫前、免疫后 20 天和 40 天内分别注射了微量元素和茉莉生长调节剂。第三个因素是注射柠檬酸，包括三个水平（0、500、1000）毫克升-1，依次用 S0、S1 和 S2 表示。结果表明，D2 处理在果实的平均直径、长度、大小、重量和总产量方面明显优于其他处理，依次达到 24.86 毫米、3.46 厘米、11.10 厘米、10.07 克、36.00 千克/棕榈-1，而对比处理的平均性状最低。至于茉莉酸的效果，注射处理优于（100 µg L-1）。(G2）的果实直径、长度、大小、重量和总产量的平均值最高，分别达到 25.90 毫米、3.63 厘米、12.09 厘米、10.93 克和 35.96 千克。就柠檬酸的影响而言，对比处理的上述性状平均值最低。超过 1000 mg.L-1 的处理（S2）在果实直径、长度、大小、重量和总产量方面的比率最高，分别达到 24.84 mm、3.49 cm、11.13 cm、9.04 g 和 36.30 kg/Palm-1。而对比处理在上述性状上的平均值最低，这也是两两交互作用和三两交互作用的结果。研究因子对所有研究性状都有显著差异：微量元素茉莉酸柠檬酸哈斯塔维品种
