Plant growth promoting bacteria in Brachiaria brizantha

Brachiaria brizantha is considered one of the preferred fodders among farmers for having high forage yield and large production of root mass. The association of beneficial bacteria with these grasses can be very valuable in the recovery of the pasture areas with nutritional deficiency. With the aim of studying this possibility, we carried out the sampling of soil and roots of B. brizantha in three areas (Nova Odessa-SP, So Carlos-SP and Campo Verde-MT, Brazil). Seventy-two bacterial strains were isolated and used in tests to evaluate their biotechnological potential. Almost all isolates presented at least one positive feature. Sixty-eight isolates produced analogues of indole-3-acetic acid, ten showed nitrogenase activity when subjected to the method of increasing the concentration of total nitrogen (total N) in the culture medium and sixty-five isolates showed nitrogenase activity when subjected to acetylene reduction technique. The partial sequencing of 16S rRNA of these isolates allowed the identification of seven main groups, with the prevalence of those affiliated to the genus Stenotrophomonas (69 %). At the end, this work elected the strains C4 (Pseudomonadaceae) and C7 (Rhodospirillaceae) as promising organisms for the development of inoculants due to their higher nitrogenase activity.

Germination of Roystonea borinquena OF Cook (Arecaceae) Seeds

This work aimed to study the effect of the temperature on the seed germination and to describe the morphology and germination process of disseminules (seeds with stucked endocarp) of R. borinquena species. The fruits were harvested and had their pulp (exocarp and mesocarp) removed and the disseminules were shade dried. The experimental design was entirely randomized and six treatments were performed (temperature conditions: constant at 25, 30 and 35 degrees C; alternated at 25-35 and 20-30 degrees C; and room temperature) with four replications with 25 disseminules per plot, placed in plastic boxes (gerbox) containing vermiculite. The germination rate and germination speed index were calculated, and the data were submitted to the variance analysis, and the means compared by the Tukey test. For the morphological studies, the external and internal sides of the disseminules, the embryo and the representative germination stages were sketched. The samples were fixed in FAA (formalin - acetic acid - ethyl alcohol). It was concluded that the highest germination rate and faster germination were at the constant temperature of 35 degrees C and alternated of 25-35 degrees C. The seeds are albuminous, with a hard endosperm that takes almost the entire interior of the disseminules; the embryo is lateral, peripheral and poorly differentiated; the germination is adjacent.

The time course of aggressive behaviour in juvenile matrinxa Brycon amazonicus fed with dietary L-tryptophan supplementation

This study evaluated the influence of dietary L-tryptophan (TRP) supplementation on the time course of aggressive behaviour and on neuroendocrine and hormonal indicators in juvenile matrinxA Brycon amazonicus. Supplementation with TRP promoted a change in the fight pattern at the beginning of an interaction with an intruder, resulting in decreased aggressive behaviours during the first 20min. The decrease in aggression did not persist throughout the interaction but increased at 3 and 6h after the beginning of the fight. Monoamine levels in the hypothalamus were not influenced by TRP before or after the fight; however, the hypothalamic serotonin (5-HT) concentration and the 5-hydroxyindole-3-acetic acid (5HIAA):5-HT ratio were significantly correlated with the reduction in aggressive behaviour at the beginning of the fight. Cortisol was not altered by TRP before the fight. After the fight cortisol increased to higher levels in B. amazonicus fed with supplementary TRP. These results indicate that TRP supplementation alters the aggressive behaviour of B. amazonicus and that this effect is limited to the beginning of the fight, suggesting a transient effect of TRP on aggressive behaviour. This is the first study reporting the effects of TRP supplementation on the time course of aggressive interaction in fishes. (C) 2013 The Fisheries Society of the British Isles
