Cucumber (Cucumis sativus L.) is one of the most widely consumed fruit vegetables throughout the world. In the present study, the effects of different concentrations of salicylic acid (0.00, 0.001, 0.01, 0.10, and 1.00 mM) and two methods of its application (foliar spraying or seed priming) were investigated on morphological and physiological traits of greenhouse cucumber cv. Dream. The application methods were one-time foliar application in four-leaf stage of seedlings and seed priming in salicylic acid solutions for 24 h. Results showed that the highest values for stem length, number of branches, number of leaves, number of fruits per plant, fruit diameter, fresh and dry weight of stems, and dry weight of leaves and fruits were obtained in seeds priming of 0.01 mM salicylic acid and other measured traits were also improved compared with control. In addition, the prevalence of disease was not observed in 0.01 mM salicylic acid. Furthermore, in treatment of 0.01 mM salicylic acid, stem diameter and stem fresh weight showed a significant increase compared with control. The highest fresh and dry weight and root volume were obtained by foliar application of 0.01 mM salicylic acid. The highest percentage of potassium and phosphorus in leaf samples were observed by foliar application of 0.10 and 1.00 mM salicylic acid. Thus, the best values for the measured traits were observed by seed priming with 0.01 mM salicylic acid.

水杨酸对黄瓜生理和形态性状的影响

黄瓜（Cucumis sativus L.）是全世界食用最广泛的水果蔬菜之一。在本研究中，研究了不同浓度的水杨酸（0.00、0.001、0.01、0.10和1.00 mM）及其两种施用方法（叶面喷洒或种子灌浆）对温室黄瓜cv形态和生理特性的影响。 。梦想。施药方法为四叶苗一次叶面施药，水杨酸溶液中种子引发24 h。结果表明，在0.01 mM水杨酸种子灌浆中，获得了最高的茎长，枝数，叶数，单株果实数，果实直径，茎的干重和鲜重以及叶和果的干重。与对照相比，酸和其他测量的性状也得到改善。此外，在0.01 mM水杨酸中未观察到疾病的流行。此外，与对照相比，在处理0.01 mM水杨酸时，茎直径和茎鲜重显着增加。通过叶面施用0.01 mM水杨酸可获得最高的鲜重和干重以及根部体积。叶面施用0.10和1.00 mM水杨酸可观察到叶片样品中钾和磷的最高含量。因此，通过用0.01 mM水杨酸引发种子，可以观察到最佳的性状值。01 mM水杨酸。叶面施用0.10和1.00 mM水杨酸可观察到叶片样品中钾和磷的最高含量。因此，通过用0.01 mM水杨酸引发种子，可以观察到最佳的性状值。01 mM水杨酸。叶面施用0.10和1.00 mM水杨酸可观察到叶片样品中钾和磷的最高含量。因此，通过用0.01 mM水杨酸引发种子，可以观察到最佳的性状值。
