In a hairy root culture of Tanacetum parthenium treated with yeast extract (YE), silver nitrate (AgNO3) and microalgal glycoproteins (MGPS), contents of four spiroketal enol ether type diacetylenes were mesured. The elicitors transiently reduced contents of three constitutive spiroketal enol ethers and selectively enhanced accumulation of cis-C13-spiroketal enol ether epoxide ((E)-3,4-epoxy-2-(2,4-hexadiynylidene)-1,6-dioxaspiro[4.4]nonane) in the roots. The most abundant formation of cis-C13-spiroketal enol ether epoxide was observed after 48-96 h of AgNO3 treatment and 96 h of YE treatment (over 3-fold increase compared with the control). The applied elicitors caused enhanced liberation of cis-C13-spiroketal enol ether epoxide to the culture medium. The results show that diacetylene accumulation pattern in the elicited hairy roots is affected in a similar manner, irrespectively of the elicitor applied.

The obligate oomycete Sclerospora graminicola (Sacc.) Schroet, is the incitant of downy mildew disease, which is the main constraint in pearl millet production worldwide. Different elicitors from Trichoderma hamatum UOM 13, e.g. mycelial extract and cell wall glucans, were assessed for their resistance elicitation efficiency and the possible underlying mechanisms. Both mycelial extract and cell wall glucans of T. hamatum UOM 13 positively influenced seed quality parameters of pearl millet, significantly enhanced seed germination and seedling vigor in comparison to the untreated control. Seed priming with cell wall glucan elicitors of T. hamatum UOM 13 suppressed downy mildew on susceptible pearl millet seedlings under greenhouse conditions by induction of systemic host resistance. Of the different elicitor delivery methods tested, transplant root dip was more effective than seed treatment and foliar spray. A combination of transplant root dip + seed treatment + foliar spray was significantly more effective than the single delivery methods. The induced resistance corresponded to up regulation of genes of important defense proteins upon pathogen inoculation. Transcripts of genes of defense enzymes glucanase, phenylalanine ammonia lyase, peroxidase and polyphenoloxidase were significantly increased due to the T. hamatum UOM elicitor effect. Expression of hydroxyproline-rich glycoprotein genes, known to play an important role in cell wall cross-linking, were also up regulated in response to T. hamatum UOM cell wall glucan treatment. This study emphasizes the role of T. hamatum UOM as a potential elicitor of downy mildew resistance in pearl millet and presents novel insights into the involvement of important defense proteins mediating such as resistance trigger.

The effect of the application of salicylic acid (SA) and hydrogen peroxide (H2 O2 ) was evaluated on sensory quality traits of two commercial sweet bell pepper varieties, Fascinato and Orangela, by descriptive sensory evaluation, principal component analysis (PCA), and Multivariate Analysis of Variance (MANOVA). A sensory descriptive lexicon was established for the sweet pepper and an intensity score was assigned for 25 sensory attributes in all the samples. Such intensity score was performed by twelve trained panelists. Among the results it was shown that foliar application of elicitors to pepper crop produced signifi cant differences in sensory traits of the harvested fruits. MANOVA allowed detecting differences in aroma profi le among treatments and varieties, showing important changes depending on the combination of elicitors applied on each variety. The principal component analysis (PCA), showed that the PC1 explained 81.02%, while PC2 explained 9.24% of the variance in the results. A strong correlation between varieties and treatments 2 (36 mM H2 O2 ) and 4 (0.1 mM SA and 36 mM H2 O2 ) with PC1 was observed. Treatments 2 and 4 were related to changes in aroma and flavor traits. Fascinato was more susceptible to the effect of elicitor than Orangela. Therefore, elicitor combinations used in this experiment were capable to improve sensory quality of peppers, and not only promote an increase in shelf life as previous studies have shown.

One of the major problems of agricultural production has been to improve the sowing qualities of seeds to increase yields of various crops. In this regard, of particular interest is the control technology of vegetable organisms by "address the impact of" signals of the physical nature. Plasma treatment of seeds influences the growth and development of the amaranth. The effectiveness of treatment depends on the exposure time of the exposure. The largest positive treatment effect of the plasma on the growth, development and yield of amaranth has been observed when the exposure 60 seconds, leading to increased yields.
