Statice ornamental plants have a great potential for use in urban landscapes, producing cut flowers and flowering pot plants. Based on the previous reports, it was our hypothesis that the use of humic materials (HM) and salicylic acid (SA) can improve the growth and yield, and also the resistance of static plants to many harsh environmental conditions. Therefore, the effect of HM at 4 concentrations of 0 (control), 2, 4 and 6 g.m⁻² (which were added as basal at the beginning of planting at the transplanting stage) and the effect of SA at 4 concentrations of 0 (control), 1, 2 and 3 mM (applied as a foliar solution every two weeks until the flowering stage was started) were evaluated on the growth characteristics of Limonium sinuatum (L.) Mill. cv. Qis Mix (Graines Voltz, France) in the research station of Horticultural department, University of Tehran in 2017−2018. Statice seeds first were planted in 45 cells trays, 50 mL volume each, containing equal volumes of peat and perlite, and 30 days’ later seedlings transferred to the pots (4 L of volume) containing sandy loam field soil and kept grown for 4 months in the field condition inside the hole in the soil level prepared for the pots. The results showed that number of cut flowers produced per pot and growth traits was significantly increased under 1 mM treatment of SA and 6 g m⁻² treatment of HM compared to control, but physiologically responded in terms of reduced ion leakage, less malone dialdehyde accumulation, less accumulation of hydrogen peroxide, and improved antioxidant enzymes activity with 1 mM of SA and with 4 g m⁻² of HM. Findings reveal that a given concentration of SA foliar application could be an alternative improvement treatment instead basal application of HM in case facing harsh environmental conditions during statice cultivation.

毋庸置疑的观赏植物在城市景观中具有巨大的潜力，可生产切花和开花盆栽植物。基于以前的报告，我们的假设是使用腐殖质材料（HM）和水杨酸（SA）可以提高生长和产量，并且还可以改善静态植物对许多恶劣环境条件的抵抗力。因此，HM在4种浓度为0（对照），2、4和6 gm ^-2（在移植阶段的种植开始时作为基础添加）的作用以及SA在4种浓度为0时的影响（（对照），1、2和3 mM（每两周以叶溶液形式施用，直到开花阶段开始）评估了枸杞（Limonium sinuatum）的生长特性（L.）米尔。简历。2017年至2018年，在德黑兰大学园艺系研究站的Qis Mix（法国Graines Voltz）。首先将静植种子种植在45个细胞托盘中，每个托盘50 mL体积，包含等量的泥炭和珍珠岩，然后30天后将幼苗转移到装有沙壤土田地的花盆（4 L体积）中，并保持生长4个月在田间条件下为盆内的土壤水平孔做好准备。结果表明，在1 mM的SA处理和6 gm ^-2的处理下，每盆切花的数量和生长性状显着增加。与对照组相比，HM的治疗，但是在1 mM的SA和4 gm ^-2的HM下，在减少离子泄漏，减少马龙二醛积累，减少过氧化氢积累和改善抗氧化酶活性方面具有生理反应。研究结果表明，在静态种植过程中遇到恶劣环境条件的情况下，给定浓度的SA叶面施肥可以替代HM基础施肥，而不是改良施肥。
