Abstract

The biochemical responses of tomato ( Lycopersicon esculentum Mill.) roots to different concentrations of the hormonal elicitors, salicylic acid (SA) and indole acetic acid (IAA), as presoaking treatments, on the healthy and Orobanche ramosa -infected plants were studied in pot experiment under control conditions. Application of SA and IAA activate the production of proline and soluble proteins in tomato roots, where their levels were more pronounced in the infected than the healthy plants. Moreover, both elicitors increased the levels of phenolics and flavonoids accompanied by stimulations in the activities of phenylalanine ammonia lyase (PAL), peroxidase (POX) and polyphenol oxidase (PPO) in tomato roots, where the magnitude of induction were more obvious in infected plants than healthy one. Also, microscopic examination revealed the anatomical differences observed in both untreated healthy and infected plants as well as in plants treated with SA and IAA. The present results indicate the effectiveness of SA and IAA in enhancing resistance of tomato to retard the incidence of infestation by Orobanche. These biochemical and histological changes involved in plant defense mechanisms may be one of the basic ways participate in the action of SA and IAA for increasing resistance in tomato against Orobanche ramosa . Keywords : Orobanche ramosa ; tomato, Induced resistance, Phenolics, PR-proteins . *Corresponding author : Shahnaz Al-Wakeel (e-mail: shahnazalwakeel@yahoo.com) (Received: 12.04.2012 Accepted: 17.07.2012)

诱导系统抗性:一种防治番茄分枝帚状油菜的创新方法
采用盆栽试验,在对照条件下,研究了不同浓度激素激发剂水杨酸(SA)和吲哚乙酸(IAA)对番茄健康植株和番茄病植株根系的生化反应。SA和IAA的施用激活了番茄根部脯氨酸和可溶性蛋白的产生,在感染植株中脯氨酸和可溶性蛋白的水平比健康植株更明显。此外,两种激发子均能提高番茄根中酚类和黄酮类物质的含量,同时刺激根中苯丙氨酸解氨酶(PAL)、过氧化物酶(POX)和多酚氧化酶(PPO)的活性,且诱导程度在侵染植株中较健康植株明显。显微镜检查还发现,未处理的健康植株和感染植株以及经SA和IAA处理的植株在解剖结构上存在差异。本研究结果表明,SA和IAA在提高番茄抗病能力、延缓赤蛾侵染方面具有一定的效果。这些涉及植物防御机制的生化和组织学变化可能是SA和IAA增强番茄对番茄斑蝽抗性的基本途径之一。关键词:山核桃;番茄,诱导抗性,酚类物质,pr蛋白。*通讯作者:Shahnaz Al-Wakeel (e-mail: shahnazalwakeel@yahoo.com)(收稿日期:12.04.2012,收稿日期:17.07.2012)
