“…Matsum and Nakai) is commonly cultivated in continuous cropping systems in monoculture and this can lead to serious problems including poor plant growth and declining production over time (Zhou and Everts, 2004). Some studies have shown that cucurbit crops are vulnerable to autotoxicity which leads to nutrient uptake disorders (Yu and Matsui, 1994) and promotion of soil-borne disease development (Ye et al, 2004). Watermelon is an important cucurbit crop species whose allelopathic potential has recently attracted widespread interest.…”

Allelopathic potential of watermelon in hydroponic culture was investigated using the continuous root exudates trapping system (CRETS). Laboratory bioassays and high-performance liquid chromatography (HPLC) were used for quantification of phytotoxins in different plant tissues and root exudates collected using XAD-4 resin. Seedling growth of both watermelon and lettuce was significantly inhibited by watermelon root exudates and the degree of inhibition increased with increasing concentration of exudates. Root exudates had inhibitory effects throughout the experiment and these were most pronounced during the period 41-50 days after transplanting. Inhibitory effects of various plant tissues were demonstrated using the bioassay tests. Frulic acid was the dominant component found using HPLC and the amounts of allelochemicals found in the plant extracts were correlated with the bioassay results using the Petri dish test. The results indicate that the allelopathic potential of watermelon may play an important role in the phenomenon referred to as 'soil sickness'. #

“…cucumerinum is the primary cause of vascular wilt in cucumber plants, and it causes substantially reduced cucumber yields in China (1)(2)(3). The symptoms of the disease begin with the development of necrotic lesions, followed by foliar wilting as the pathogen invades the vascular system of the plant, and eventually, plant death (4).…”

cBacillus amyloliquefaciens strains are capable of suppressing soilborne pathogens through the secretion of an array of lipopeptides and root colonization, and biofilm formation ability is considered a prerequisite for efficient root colonization. In this study, we report that one of the lipopeptide compounds (bacillomycin D) produced by the rhizosphere strain Bacillus amyloliquefaciens SQR9 not only plays a vital role in the antagonistic activity against Fusarium oxysporum but also affects the expression of the genes involved in biofilm formation. When the bacillomycin D and fengycin synthesis pathways were individually disrupted, mutant SQR9M1, which was deficient in the production of bacillomycin D, only showed minor antagonistic activity against F. oxysporum, but another mutant, SQR9M2, which was deficient in production of fengycin, showed antagonistic activity equivalent to that of the wild-type strain of B. amyloliquefaciens SQR9. The results from in vitro, root in situ, and quantitative reverse transcription-PCR studies demonstrated that bacillomycin D contributes to the establishment of biofilms. Interestingly, the addition of bacillomycin D could significantly increase the expression levels of kinC gene, but KinC activation is not triggered by leaking of potassium. These findings suggest that bacillomycin D contributes not only to biocontrol activity but also to biofilm formation in strain B. amyloliquefaciens SQR9.

“…which carries many problems with it, such as deterioration of soil physicochemical properties (Ye et al, 2004), adverse effects on soil structure (Huang et al, 2006) and the build-up of soil-borne diseases and autotoxicity (Ahmad et al, 2013). So mono-cropping system has negative impacts on the soil physical properties and structure, thus intercropping system is the better option to address these problems.…”
