“…Silver vase bromeliads cultivated under Ca omission or complete Hoagland and Arnon medium (1950) did not show difference on plant growth and plants submitted Ca omission do not exhibit visual symptoms of Ca deficiency (Young et al, 2018), corroborating our results. Ca deficiency symptoms in pineapple initially are observed on the fruit because the demand for calcium is highest at the time of floral differentiation (Malézieux and Bartholomew, 2003).…”

“…The increase of Ca in fertilizer solutions also increase Ca contents in leaves of silver vase bromeliad; conversely, N, P and Mg contents in leaves decreased (Table 2), showing an antagonism effect. Young et al (2018) observed lower values of Ca contents in leaves of silver vase bromeliads on treatment with Ca omission (3.66 g kg -1 ) and the equivalent Ca content as observed on our data on complete treatment (13.00 g kg -1 ).

The present study aimed to evaluate the effect of different concentrations of calcium on growth and development of silver vase bromeliad (Aechmea fasciata). Plants were fertilized three times a week with nutrient solutions formulated with HA solution (Hoagland and Arnon, 1950) modified with 0.25, 2.5, 5, 7.5, 10.0 or 12.5 mM Ca applied into the tank. After 90 days of experimentation, biometric and biomass measurements of root and shoot systems, and chemical analysis of leaves were assessed. The results showed that the concentration of 12.5 mM Ca in nutrient solution is recommended for silver vase bromeliad fertilization.

“…Notwithstanding, low P availability in agricultural soils is a pressing issue that affects over two billion hectares worldwide (Oberson et al, 2001). For instance, P deficiency was reported to cause a significant reduction (5-15%) of crop yield (Shenoy and Kalagudi, 2005) with P-deficient plant symptoms characterized by reddish leaves and necrosis in old leaves tips (Luiz et al, 2018). Generally, P availability in most soils depends on multiple factors, notably the ions concentration and soil pH (Hinsinger et al, 2018).…”

Phosphate Solubilizing Rhizobacteria Could Have a Stronger Influence on Wheat Root Traits and Aboveground Physiology Than Rhizosphere P Solubilization

et al. 2020

Limited P availability in several agricultural areas is one of the key challenges facing current agriculture. Exploiting P-solubilizing bacteria (PSB) has been an emerging bio-solution for a higher rhizosphere P-availability, meanwhile the above-and below-ground interactions that PSB would trigger remain unclear over plant growing stages. We hypothesized that PSB effects on plant growth may be greater on root traits that positively links with aboveground physiology more than the commonly believed rhizosphere P bio-solubilization. In this study, five contrasting PSB (Pseudomonas spp.) isolates (low "PSB 1 ", moderate "PSB 2 and PSB 4 " and high "PSB 3 and PSB 5 " P-solubilizing capacity "PSC") were used to investigate aboveand below-ground responses in wheat fertilized with rock P (RP) under controlled conditions. Our findings show that all PSB isolates increased wheat root traits, particularly PSB 5 which increased root biomass and PSB 3 that had greater effect on root diameter in 7-, 15-and 42day old plants. The length, surface and volume of roots significantly increased along with higher rhizosphere available P in 15-and 42-day old plants inoculated with PSB 4 and PSB 2. Shoot biomass significantly increased with both PSB 2 and PSB 5. Root and shoot physiology significantly improved with PSB 1 (lowest PSC) and PSB 4 (moderate PSC), notably shoot total P (78.38%) and root phosphatase activity (390%). Moreover, nutrients acquisition and chlorophyll content increased in inoculated plants and was stimulated (PSB 2 , PSB 4) more than rhizosphere P-solubilization, which was also revealed by the significant above-and below-ground inter-correlations, mainly chlorophyll and both total (R = 0.75, p = 0.001**) and intracellular (R = 0.7, p = 0.000114*) P contents. These findings demonstrate the necessity to timely monitor the plant-rhizosphere continuum responses, which may be a relevant approach to accurately evaluate PSB through considering below-and above-ground relationships; thus enabling unbiased interpretations prior to field applications.

“…Adequate mineral nutrition is a fundamental factor for bromeliads growth and development in all life stages (Tamaki et al, 2011). Nitrogen, phosphorus and potassium are the most limiting elements for growth and biomass production of silver vase bromeliad, once the omission of these elements causes great decrease in biometric parameters (Young et al, 2018). Furthermore, epiphytic bromeliads fertilized in the roots (substrate) have a greater investment in biomass than when fertilized only in the tanks (Silva et al, 2018).…”

The bromeliads are desirable vase plants because of the flowering bract and the usually large, bold, colored and exotic format of the leaves that forms a cistern. The main function of epiphytic bromeliads roots is the fixation on the substrate, while water and nutrients uptake are performed mainly by leaves. However, recent studies have shown that the roots of epiphytic bromeliads can also help in the absorption of water and nutrients, contributing to plant growth and development. The present study aimed to evaluate the importance of the root system in the mineral nutrition of an epiphytic ornamental bromeliad silver vase bromeliad (Aechmea fasciata) that occurs in Brazil. 80 plants were cultivated for 240 days in plastic pots (900 mL) containing composted pine bark and were subjected to 5 treatments with 50 mL of 0% (control), 25%, 50%, 75% and 100% Hoagland & Arnon (HA) nutrient solution, applied twice a week only onto the substrate. Biometric and biomass variables of root and shoots, as well as macro- and micronutrients content in silver vase bromeliad leaves were evaluated. Results showed that all biometric and biomass parameters increased with the application of increasing HA solution concentrations, while the nutritional content in leaves showed different responses, with increase in nitrogen and potassium, decrease in calcium, phosphorus, magnesium, manganese, copper, sulfur, iron and zinc. We conclude that silver vase bromeliad grows better when fertilized with 75% or 100% HA solution on the substrate. We emphasize that the roots of the epiphytic silver vase bromeliad are functional and plays important roles in its nutrition and growth.
