“…and Bacillus spp., have also been reported to stimulate plant growth under dry conditions. Inoculation under drought conditions increased shoot and root biomass and water content (Marulanda et al 2009). Increased root elongation and root biomass are common in drought-tolerant species (Sharp et al 2004).…”

“…For example, inoculation of white clover (Trifolium repens) with the IAA-producing strains of P. putida and B. megaterium, resulted in increased shoot and root biomass and water content under drought conditions (Marulanda et al 2009). In addition to IAA, abscisic acid (ABA) is another plant hormone that plays an important role in the whole plant response to drought stress.…”

Agricultural uses of plant biostimulants

Background Plant biostimulants are diverse substances and microorganisms used to enhance plant growth. The global market for biostimulants is projected to increase 12 % per year and reach over $2,200 million by 2018. Despite the growing use of biostimulants in agriculture, many in the scientific community consider biostimulants to be lacking peer-reviewed scientific evaluation. Scope This article describes the emerging definitions of biostimulants and reviews the literature on five categories of biostimulants: i. microbial inoculants, ii. humic acids, iii. fulvic acids, iv. protein hydrolysates and amino acids, and v. seaweed extracts.Conclusions The large number of publications cited for each category of biostimulants demonstrates that there is growing scientific evidence supporting the use of biostimulants as agricultural inputs on diverse plant species. The cited literature also reveals some commonalities in plant responses to different biostimulants, such as increased root growth, enhanced nutrient uptake, and stress tolerance.

“…La significancia estadística que se observó en las variables de crecimiento para años (Cuadro 2), indica un comportamiento diferencial entre ciclos, atribuido a las condiciones ambientales que se presentaron. Marulanda et al (2009) señalaron un efecto directo de la humedad, la temperatura y la luminosidad entre otros factores sobre el funcionamiento de los microorganismos.…”

Lilium sp. se ubica entre las especies de mayor importancia en la producción de flores de corte en México, pero su cultivo se basa en la utilización de cantidades importantes de fertilizantes químicos, por lo que es deseable minimizar el impacto sobre el ecosistema sin disminuir la calidad del producto. Este estudio se realizó con el objetivo de evaluar los efectos principales y las interacciones de fósforo, Glomus fasciculatum y Bacillus subtilis, sobre la calidad comercial de f lores de Lilium híbrido oriental Showwinner en condiciones de invernadero. En dos ciclos consecutivos entre 2007 y 2008 se estudiaron 12 tratamientos bajo un arreglo factorial 2∗3∗2 aplicando análisis de varianza, comparación de medias de tratamientos con la prueba de la diferencia mínima significativa (DMS, p= 0.05) y análisis de componentes principales. G. fasciculatum, 22 μg ml-1 de fósforo y B. subtilis tuvieron correlación positiva con peso seco de raíz, altura de la planta, peso seco del tallo, ancho de pétalo, diámetro de la f lor, peso seco de la f lor, vida de la f lor, período de f loración y concentración en los tallos de zinc (Zn), cobre (Cu), potasio (K), nitrógeno (N), fósforo (P) y calcio (Ca). Estos resultados muestran que los microorganismos rizósfericos utilizados, pueden interactuar positivamente para promover el crecimiento y el desarrollo de la planta y mejorar la calidad de Lilium sp. con 22 μg ml-1 de fósforo.

The sunflower (Helianthus annuus L. cv. PAC 36) seedlings were inoculated with plant growth promoting rhizobacteria (PGPR), viz. Azotobacter chroococcum (A+), Bacillus polymyxa (B+), separately and in combination of the two (AB+). Relative water content and seedling growth were maximum in AB+ seedlings under control. Water stress significantly decreased the RWC, growth and dry mass of non-inoculated seedlings. However, inoculated seedlings maintained higher growth even under water stress. Pigments and protein contents decreased under water stress, but higher amount of the same was observed in stressed AB+ seedlings. Enhanced activity of nitrate reductase was recorded in AB+ seedlings with maximum in control. Water stress significantly decreased the nitrate reductase activity. A significant increase in the activity of superoxide dismutase (SOD) in leaves was recorded under water stress except in B+ with maximum increase in non-inoculated seedlings. Catalase (CAT) activity decreased in stressed non-inoculated seedlings while increased in the leaves of A+ and AB+ seedlings. Almost similar trends were recorded for both leaves and cotyledons. PGPR improved the water status in stressed seedlings and thereby physiological and biochemical parameters and thus ameliorated the severe effects of water stress.
