| ABSTRACT This study investigated whether inoculation of Azospirillum brasilense in the seeds or sowing furrow could reduce the need for nitrogen fertilizer application in the corn grown in the first and second crop harvest. The experiments were conducted, in the municipality of Chapadão do Sul, MS, Brazil, in the first crop harvest (2014/2015) and in the second crop harvest (2016). The early maturity hybrids CD 384 HX and P3132H were used in the first and in the second harvest corn, respectively. In both experiments, the experimental design was the randomized blocks with eight treatments and three repetitions. At the silking (R1 stage), the leaf N concentration, relative chlorophyll index and nitrate reductase activity were measured, at the physiological... |

| Aspasia variegata occurs naturally in the savanna of the Mato Grosso do Sul State, Brazil and it has been widely collected for its beautiful flowers. Additionally, its habitat has been greatly reduced and little or no investigation of its spread has been performed. Aiming to establish a protocol to obtain seedlings of the orchid A. variegata, different compositions of culture medium were tested to identify which one provided better in vitro growth and development and to assess the influence of these media in seedling acclimatisation. Thus, seeds obtained from mature capsules were inoculated in Knudson culture medium for 120 days until the protocorm stage. They were transferred to different culture media formulations, including MS and Knudson with half or... |
