“…However, this tendency is not generally valid for all nematode species and all plant hosts. In the case of the banana Prata-Ana, the decreased egg and gall mass/root and number of second juveniles of Meloidogyne javanica per defined soil volume were not observed in silicon treated plants [170] and there were no ameliorative effects of Si in maize plants infested by this pathogen. On the other hand, significant positive effects of Si were observed in soybean, common bean, and rice [161].…”

Silicon (Si) is not considered an essential element, however, its tissue concentration can exceed that of many essential elements in several evolutionary distant plant species. Roots take up Si using Si transporters and then translocate it to aboveground organs. In some plant species, root tissues are also places where a high accumulation of Si can be found. Three basic modes of Si deposition in roots have been identified so far: (1) impregnation of endodermal cell walls (e.g., in cereals, such as Triticum (wheat)); (2) formation of Si-aggregates associated with endodermal cell walls (in the Andropogoneae family, which includes Sorghum and Saccharum (sugarcane)); (3) formation of Si aggregates in “stegmata” cells, which form a sheath around sclerenchyma fibers e.g., in some palm species (Phoenix (date palm)). In addition to these three major and most studied modes of Si deposition in roots, there are also less-known locations, such as deposits in xylem cells and intercellular deposits. In our research, the ontogenesis of individual root cells that accumulate Si is discussed. The documented and expected roles of Si deposition in the root is outlined mostly as a reaction of plants to abiotic and biotic stresses.

Silicates have the potential to induce disease resistance in plants. Induction of nematode resistance usually results from paralysis of nurse cell development or activation of the hypersensitivity response. This study aimed to evaluate the effects of silicon (Si) treatment on the penetration and development of Meloidogyne javanica in various crops. The experiment was set up in a randomized (3 × 4) + 1 factorial design, with 3 Si sources (Silifort®, Rocksil® and wollastonite), 4 crops (maize, rice, common bean and soybean) and 1 treatment control (distilled water). The Si treatments included adding wollastonite to the soil 10 days prior to seedling transplantation, or spraying with solutions of Silifort® or Rocksil®, 2 days after seedlings transplantation. Twelve days after transplantation, the plants were inoculated with 1000 eggs and eventual second‐stage juveniles (J2) of M. javanica. At 3, 8, 13 and 18 days after inoculation (DAI), the plants were harvested and nematode penetration evaluated by optical microscopy. All Si treatments adversely affected development of M. javanica in soybean, common bean and rice and reduced nematode penetration of rice roots. Silifort® and wollastonite reduced nematode penetration in common bean and soybean roots, respectively. However, none of the Si treatments influenced the variables analysed in maize. The results of this study illustrate the potential of Si treatment to control M. javanica parasitism in plants.

Resumo -O objetivo deste trabalho foi avaliar o efeito de indutores de resistência abióticos no controle da fusariose (Fusarium guttiforme) do abacaxizeiro na fase pré-colheita, em área de ocorrência natural da doença, e verificar se promoveram alterações físico-químicas e bioquímicas nos frutos. Os produtos testados foram fosfito de potássio, fosfito de cálcio, fosfito de cobre, Agro-Mos, silicato de cálcio, Biopirol e Bion pulverizados em campo, nas dosagens recomendadas pelos fabricantes. Fosfito de potássio, Biopirol e fosfito de cobre foram os mais eficientes na redução da incidência da fusariose do abacaxizeiro em campo, com 91,67, 70,01 e 67,68% de controle, respectivamente. As análises físico-químicas mostraram que os tratamentos não promoveram alteração no pH, nos sólidos solúveis totais e na acidez total dos frutos, enquanto, nas análises bioquímicas, apenas a β-1,3-glucanase apresentou menor atividade em relação à testemunha (água destilada esterilizada), com exceção do tratamento com fosfito de potássio. Assim, a adubação foliar com fosfito de potássio e fosfito de cobre, assim como o tratamento com o Biopirol, podem auxiliar no controle da fusariose do abacaxi.Termos para indexação: Fusarium guttiforme, Agro-Mos, Bion, fosfitos, silicato. Abiotic resistance inducers for control of pineapple fusariosisAbstract -The objective of this work was to evaluate the effect of abiotic resistance inducers on the control of pineapple fusariosis (Fusarium guttiforme) in the pre-harvest period, in an area with natural occurrence of the disease in the field, and to check for any physicochemical and biochemical changes in the fruits. The products tested were potassium phosphite, calcium phosphite, copper phosphite, Agro-Mos, calcium silicate, Biopirol, and Bion sprayed on the field, at the dosages recommended by the manufacturers. Potassium phosphite, Biopirol, and copper phosphite were the most effective in reducing the incidence of pineapple fusariosis in the field, with 91.67%, 70.01%, and 67.68% of control, respectively. The physicochemical analyses showed that the treatments did not promote change in pH, total soluble solids, and total acidity of fruits, while, in biochemical analyses, only β-1,3-glucanase showed lower expression compared with the control (sterilized distilled water), except for the treatment with potassium phosphite. Therefore, foliar fertilization with potassium phosphite and copper phosphite, as well as the treatment with Biopirol, may aid in the control of pineapple fusariosis.
