Salinity is one of the abiotic stresses that affect crop growth and productivity in arid and semi-arid regions. Unfortunately, there are few known methods to mitigate the deleterious impacts of salt stress on the development and yield of vegetable crops. Blue-green algae (cyanobacteria) are endowed with the potential to curb the negative impacts of salt stress as they are characterized by biostimulant properties. The present work aimed to investigate the effects of Roholtiella sp. as a foliar extract on the growth characteristics, physiological and biochemical responses of bell pepper (Capsicum annuum L.) plants under varying levels of salinity conditions. A soilless water experiment was carried out in a greenhouse where bell pepper seedlings were grown under five salt concentrations (0, 50, 200, 150, and 200 mM of NaCl). Growth characteristics, pigments content, relative water content, and antioxidant activity (CAT) were determined. Our results showed that growth parameters, relative water content (RWC), chlorophyll a & b concentrations under salinity conditions were negatively affected at the highest concentration (200 mM). Interestingly, the application of Roholtiella sp. foliar extract enhanced the plant growth characteristics as shoot length increased by 17.014%, fresh weight by 39.15%, dry and weight by 31.02%, at various salt treatments. Moreover, chlorophyll a and b increased significantly compared with seedlings sprayed with water. Similarly, RWC exhibited a significant increase (92.05%) compared with plants sprayed with water. In addition, antioxidants activities and accumulation of proline were improved in Roholtella sp. extract foliar sprayed seedlings compared to the plants foliar sprayed with water. Conclusively, at the expiration of our study, the Rohotiella sp. extract-treated plants were found to be more efficient in mitigating the deleterious effects caused by the salinity conditions which is an indication of an enhancement potential of tolerating salt-stressed plants when compared to the control group.

E-mail: [email protected]  1 RESUMO  Neste estudo, objetivou-se determinar os teores de micronutrientes (Fe, Zn, Mn, B e Cu) nos diferentes órgãos do híbrido de pimentão Elisa, sob fertirrigação em ambiente protegido, em oito épocas de coleta de planta. O experimento foi desenvolvido nas dependências do Departamento de Recursos Naturais - Ciência do Solo, FCA, Botucatu/SP. Constou o experimento de 8 tratamentos (épocas de coleta de planta – 0, 20, 40, 60, 80, 100, 120, e 140 dias após o transplante das mudas) e 4 repetições, sendo cada repetição formada por 4 plantas. Em cada etapa obteve-se os teores dos micronutrientes no fruto, folha, caule e raiz e na planta como um todo. A fertilização no ciclo estudado, 140 dias, foi feita via fertirrigação localizada. Os resultados mostram que os teores de micronutrientes encontrados na planta de pimentão seguem a seqüência: Fe>Zn>Mn>B>Cu. Nos resultados são apresentadas as tabelas com os teores de Fe, Zn, Mn, B e Cu (Tukey a 5%) em cada órgão da planta e da planta como um todo, nas diferentes épocas de avaliação e, os gráficos mostrando o comportamento dos teores de Zn, Mn, B e Cu.  UNITERMOS: Fertirrigação, concentrações de micronutrientes, Pimentão, Capsicum annuum L. e nutrição mineral.   MACUSSI, F.F.N.; VILLAS BÔAS, R.L MICRONUTRIENT CONCENTRATION IN THE BELL PEPPER PLANT DEVELOPMENT UNDER FERTIRRIGATION   2 ABSTRACT  This study aimed to determine the micronutrient contents (Fe, Zn, Mn, B and Cu) in different organs of Elisa bell pepper hybrid under fertirrigation in protected environment in eight harvesting seasons. The experiment was carried out in the Natural Resource Department – Soil Science, FCA, Botucatu. SP, and  consisted of 8 treatments (harvesting season – 0, 20, 40, 60, 80, 100 and 140 days after seedling transplant), and 4 replications, each one composed of 4 plants. In each growth period the micronutrient content in the fruit, leaf, stem, root and  plant as a whole was determined. The fertilization in the study period i.e., 140 days, was performed by local fertirrigation. The results showed that the micronutrient levels found in the bell pepper plant followed the decreasing order: Fe>Zn>Mn> B>Cu. The tables present the Fe, Zn, Mn, B and Cu (Tukey Test at 5%) contents in each plant organ and in the entire plant at different evaluation periods. The charts show the Zn, Mn, B and Cu content variation.  KEYWORDS: fertirrigation, micronutrient concentration, bell pepper, Capsicum annuum L. and mineral nutrition.
