Physiological Role of Fenugreek Seeds as Biological Control for Tomato Wilt Disease.

Abstract
A greenhouse pot experiment was conducted to study the allelopathic potential of fenugreek (Trigonella foenum-graecum L.) seed incorporated into the soil on some physiological and biochemical changes associated with the growth and development of tomato (Lycopersicon esculentum Mill.) plants. Also, the ability of different fenugreek treatments to overcome the deleterious effects induced by Fusarium oxysporum f. sp lycopersici on tomato plants was studied.
HPLC analysis of fenugreek seed revealed the presence of eight phenolic compounds including: salicylic, syringic, vanillic, chlorogenic,
p-coumaric, p-hydroxybenzoic and protocatechuic acids, as well as•••-• coumarin. Six of these phenolics were similarly present in fenugreek powder and extract, but varied in their concentrations. In addition, the
two other compounds were detected only in the fenugreek seed powder.
Incorporation of the upper layer of soil with fenugreek seed extract at the lower concentrations of 0.25% and 0.50% (v/w, extract/soil) and with seed powder at the lower rates of 0.05% and 0.10% (w/w, powder/soil) stimulated the root and the shoot growth of tomato plants throughout the different stages of growth. This positive response was concomitant with the accumulation of total phenolic compounds,
