“…Therefore, biochar addition to the peat, could result in a change in strawberry fruit composition, which could make them less susceptible for B. cinerea infection. This effect of biochar on the overall composition of the strawberry fruits will be tested in future experiments, based on the protocol described in Palencia et al (2016). …”

Adding biochar, the solid coproduct of biofuel production, to peat can enhance strawberry growth, and disease resistance against the airborne fungal pathogen Botrytis cinerea. Additionally, biochar can induce shifts in the strawberry rhizosphere microbiome. However, the moment that this biochar-mediated shift occurs in the rhizosphere is not known. Further, the effect of an above-ground infection on the strawberry rhizosphere microbiome is unknown. In the present study we established two experiments in which strawberry transplants (cv. Elsanta) were planted either in peat or in peat amended with 3% biochar. First, we established a time course experiment to measure the effect of biochar on the rhizosphere bacterial and fungal communities over time. In a second experiment, we inoculated the strawberry leaves with B. cinerea, and studied the impact of the infection on the rhizosphere bacterial community. The fungal rhizosphere community was stabilized after 1 week, except for the upcoming Auriculariales, whereas the bacterial community shifted till 6 weeks. An effect of the addition of biochar to the peat on the rhizosphere microbiome was solely measured for the bacterial community from week 6 of plant growth onwards. When scoring the plant development, biochar addition was associated with enhanced root formation, fruit production, and postharvest resistance of the fruits against B. cinerea. We hypothesize that the bacterial rhizosphere microbiome, but also biochar-mediated changes in chemical substrate composition could be involved in these events. Infection of the strawberry leaves with B. cinerea induced shifts in the bacterial rhizosphere community, with an increased bacterial richness. This disease-induced effect was not observed in the rhizospheres of the B. cinerea-infected plants grown in the biochar-amended peat. The results show that an above-ground infection has its effect on the strawberry rhizosphere microbiome, changing the bacterial interactions in the root-substrate interface. This infection effect on the bacterial rhizosphere microbiome seems to be comparable to, but less pronounced than the effect of biochar-addition to the peat. The biological meaning of these observations needs further research, but this study indicates that biochar and an above-ground pathogen attack help the plant to recruit rhizosphere microbes that may aid them in their plant growth and health.

“…[13] demonstrated that the substrate of hydroponically grown long-mat seedlings could replace the traditional substrate or nutritive soil in rice seedling production. However, the physical and chemical properties such as bulk density, ion content and ion adsorption capacity of substrates, especially organic substrates, exhibit significant differences among regions [14,15] , which sometimes leads to the growth and yield attained with mixed substrates vary obviously under different cultivation practices [16,17] . At present, most of commercial mixed substrates sometimes have difficulty to meet the needs of crop varieties, which may lead to slowed growth, reduced yields and other serious consequences [7,18] .…”

In soilless culture, a suitable mixed substrate that provides a balanced and stable rhizosphere environment is vital for promoting plant growth. The present study was undertaken to establish seven prediction models of physical and chemical properties, including bulk density (DB), total porosity (TP), water-holding porosity (WHP), air porosity (AP), WHP/AP, electrical conductivity (EC) and cation exchange capacity (CEC) of mixed substrate based on regression equations of measured values from 76 substrate combinations. These seven models were verified using the measured values of 12 mixed substrates, and the average relative prediction errors (REs) were all less than 10%. A comprehensive property prediction model was established by weighted summation of the seven models of physical and chemical properties. According to the set values of DB, TP, WHP, AP, WHP/AP, EC and CEC, the comprehensive property model predicted the six mixture proportions of mixed-substrate, as verified using the measured values. This study is the first to establish prediction models for the physical and chemical properties of mixed substrates. The comprehensive property model could be used to evaluate the physical and chemical properties of commercial mixed substrates, and to provide the optimal mixture substrate formulations according to the setting property value of production requirement.

La fresa (Fragaria x ananassa Duchesne) es un cultivo importante en México y el mundo. Para incrementar el rendimiento se han explorado varios sistemas de producción, como los sistemas hidropónicos. El objetivo de este estudio fue determinar el efecto de cultivares de fresa, densidades y estratos de plantación en sistema hidropónico piramidal, en el desarrollo de las plantas, producción y calidad de frutos. El estudio se realizó en Salinas de Hidalgo, SLP, México, en el ciclo primavera-otoño de 2017. El factor estrato impacto en el desarrollo y rendimiento del cultivo, con el estrato alto se incrementó el número de hojas, ancho de la corona, número de frutos y rendimiento (23.5 kg m-2), y cantidad de sólidos solubles en comparación con los inferiores. Las plantas en estratos intermedios fueron menos productivas, probablemente por la sombra causada por las de estrato más alto. La densidad y el cultivar no tuvieron efecto significativo en el desarrollo, rendimiento y calidad de fruto.
