摘要

为了解高粱品种(Rabih、Khair、Inqath)对水杨酸喷洒浓度的响应,于2022年春季在Al-Muthanna大学农学院第二农业研究站进行了田间试验。试验共设12个处理,分别为拉比、海尔、安卡达3个品种,喷施4种浓度的水杨酸(0、60、90、120)ppm。试验按R.C.B.D设计为3个重复,主试验区为3个高粱品种,次试验区为4个水杨酸水平。结果表明,该品种在茎粗、叶面积、籽粒、籽粒等性状上均具有优势。每穗粒数分别为20.35 mm、303.00 cm2和1214粒/穗-1。水杨酸浓度为120毫克。L-1对(no.;穗粒数、千粒重和收获指数分别为- 1461粒/穗、- 33.30 g和- 29.79%。凯尔擅长虽然品种叶面积和茎直径的特点分别(303.9厘米2和20.35毫米),以及一个显著的影响水平120 ppm的特质(开花天数从种植到75%,每个植物的叶子数量,数量的谷物在耳朵,和体重1000粒,籽粒产量、生物产量、收获指数达到93.78天,9.45 leaf-1, 1494年谷物ear-1, 32.96 g,是3.46吨,12.59吨农业,29.76%)顺序。各因子互作对穗粒数影响显著,其中组合(品种Inqath ×水平120 ppm) 2017年穗粒数平均最高。

Response of sorghum cultivars (Sorghum bicolor L.) to spraying different concentrations of salicylic acid
A field experiment was carried out at the second agricultural research station – College of Agriculture – University of Al-Muthanna during spring season 2022, to find out response of cultivars of sorghum (Rabih, Khair, Inqath) to spraying concentrations of salicylic acid. The experiment included 12 treatments represent between three cultivars (Rabih, Khair, Anqadh) and spraying of four concentrations of salicylic acid (0, 60, 90, 120)ppm, The Experiment was designed in split plots according to R.C.B.D with three replicates, The main plots included three cultivars of sorghum, while the secondary sub plots It included four levels of salicylic acid. Results showed that cultivar of Khair was superior at the traits Stem diameter, leaf area, no. of grains per ear which gave (20.35 mm, 303.00 cm2 and 1214 grain per- ear-1) respectively. As for salicylic acid the concentration 120 mg. L-1 was significant on the (no. grains per- ear, weight of 1000 grain and harvest index which gave (1461 grain per- ear -1, 33.30 g and 29.79 %) respectively. while the cultivar Khair excelled in the trait of leaf area and stem diameter (303.9 cm2 and 20.35 mm) respectively, as well as a significant effect of the level 120 ppm in the trait (number of days from planting to 75% flowering, number of leaves per plant, number of grains in ear, and Weigh of 1000 grains, grain yield, biological yield, harvest index (it amounted to 93.78) days, 9.45 leaf-1 , 1494 grain ear-1 , 32.96 g, 3.46 tons ha-1 , 12.59 tons ha-1 , 29.76%) sequentially. Significant effect of the interaction between the factors on the number of grains in the ear, as the combination (cultivars Inqath × level 120 ppm) recorded the highest average amounted to 2017 grain ear-1 .
