Preliminary study on phytoalexin induction in cucumber.
Wang J,   Wang B,   Zhao H,   Li B  

Abstract
Inducer can induce new active composition and increase the content of the active composition in the plant. In this paper, we investigated the synthesis and accumulation of phytoalexin in cucumber seedlings which were induced by chemical inducer of the salicylic acid (SA) and physical inducer. Analyzed by experiment of antifungal activity, thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC), the result was that both SA and stress can induce the synthesis and accumulation of phytoalexin in cucumber seedlings. But the content of phytoalexin induced by SA was lower than it induced by stress. And in this paper, another conclusion was that the transduction of physical signal and the chemical signal in the plant depended on the adhesion between cell wall and plasma and active oxidative species producted by stimulation.
