SUMMARYThe present investigation was designed to assess the range of growth-promoting activities of various rhizosphere bacteria on wheat and oat growing in Lanzhou, China. Detection of the N-fixing bacteria by the acetylene reduction assay-based most probable number (ARA-based MPN) method indicated the presence of significant numbers of N-fixing rhizobacteria, i.e. 5·8×106bacteria/g dry weight of root in association with Chinese wheat varietyV4. A total of 24 rhizobacteria was isolated from wheat and oat grown in Lanzhou, China. These bacterial isolates were studied for growth characteristics, nitrogen fixation, phosphate solubilization and indole acetic acid (IAA) production. All the isolates were motile and gram negative. Acetylene reduction activity was detected in all isolates ranging from 124·6 to 651·6 nmol C2H2reduced/h/vial while almost all isolates produced IAA ranging from 0·2 to 5·1 μg/ml. Only two isolates, ChW1 and ChW6, formed clear zones on Pikovskaia's medium, showing the ability to solubilize phosphates. ChW1 and ChW6 were used to develop fluorescent antibodies to check the cross reactivity of the isolates. Inoculation of these bacterial isolates resulted in higher plant biomass, root area and total N content on Chinese wheat varietyNingchun 2and Pakistani oat varietySwanunder controlled conditions. Among the wheat isolates, ChW5 was the best in promoting wheat growth by increasing its root length, root area, shoot dry weight and total N content. Among oat isolates, ChO3, ChO5 and ChO6 showed significant effects on different growth parameters of their host plants. Using the15N isotope dilution method, the highest N fixation contribution (0·73 of total plant N) was observed in the wheat plants inoculated with isolate ChW5. Random amplified polymorphic DNA (RAPD) analysis of seven selected isolates showed that the variation within the isolates from different host crops grown in the same soil was quite large and helpful not only in defining the bacterial strains associated with different host crops but also in defining the distances of isolates from standard strains of rhizobacteria used. In conclusion, the present results indicate that the selected bacterial isolates did promote the growth of wheat and oat in ways that could be harnessed to practical benefit for the farmer and consistent with sustainable agricultural practices in China.

Wheat production is a determining branch within Hungarian crop production (near 1 million hectares). Weather anomalies caused by climatic change confirmed the importance of biological basis (variety, hybrid) in wheat production. The adapting ability and reaction of different wheat genotypes towards nutrient supply were studied in a long-term field experiment on chernozem soil type in case of different pre-crops (sweet corn, sunflower and maize). According to the experimental results of the vegetation 2017/2018 the most highest yield amount of the variety Ingenio sown after the pre-crop sunflower ranged between 2710 kg ha-1 and 8710 kg ha-1, while the hybrid (Hyland) in case of the pre-crop sweet maize between 6556 kg ha-1 and 9270 kg ha-1 depending on the applied nutrient supply level. The studied genotypes showed the highest quality (protein, gluten) in case of the pre-crop sweet maize. In the cropyear of 2017/2018, the protein content of Ingenio ranged between 12.2-14.8%, while the Hyland in case of the pre-crops sweet corn between 9.9-13.9%. The gluten content of the Ingenio genotype changed between 24.9-32.5%, in the case of Hyland ranged between 16.9-27.3% in the studied cropyear.

Effects Of Temperature

Dough quality from grain samples from the Interstate Wheat Variety Trials for 3 cultivars at Wongan Hills and Narrabri in 6 seasons and 4 cultivars at Narrabri, Wagga Wagga and Dooen in 4 seasons was studied in relation to av. daily min. and max. temp. from anthesis to harvest. In greenhouse experiments, wheat cv. Olympic, Hartog and Skua seedlings were raised at day/night temp. of 21/16degreesC and then transferred to 33/28degrees at 14 or 32 d after anthesis. Air temp. influenced wheat baking quality, particularly dough strength, loaf score and volume in both field and greenhouse trials. Dough strength increased with av. daily temp. up to 30degrees and tended to decrease at higher temp. Field data indicated that protein concn was most dependent on max. temp. The cultivars differed in inherent dough strengths but for all cultivars dough strength increased with protein concn, and a strong positive correlation with max. temp. was observed. In the greenhouse, high temp. increased grain moisture loss and shortened the time to maturity. Grain from the higher temp. regime was smaller and the dough particularly resistant to deformation. Loaf volume was very similar for all 3 cultivars but for other quality characteristics responses differed between cultivars.

The combined interactions of mode and tempo on emotional responses to music were investigated using both self-reports and electroencephalogram (EEG) activity. A musical excerpt was performed in three different modes and tempi. Participants rated the emotional content of the resulting nine stimuli and their EEG activity was recorded. Musical modes influence the valence of emotion with major mode being evaluated happier and more serene, than minor and locrian modes. In EEG frontal activity, major mode was associated with an increased alpha activation in the left hemisphere compared to minor and locrian modes, which, in turn, induced increased activation in the right hemisphere. The tempo modulates the arousal value of emotion with faster tempi associated with stronger feeling of happiness and anger and this effect is associated in EEG with an increase of frontal activation in the left hemisphere. By contrast, slow tempo induced decreased frontal activation in the left hemisphere. Some interactive effects were found between mode and tempo: An increase of tempo modulated the emotion differently depending on the mode of the piece.

Abstract. Background: Acute suicidal affective disturbance (ASAD) has been proposed as a suicide-specific entity that confers risk for imminent suicidal behavior. Preliminary evidence suggests that ASAD is associated with suicidal behavior beyond a number of factors; however, no study to date has examined potential moderating variables.  Aims: The present study tested the hypotheses that physical pain persistence would moderate the relationship between ASAD and (1) lifetime suicide attempts and (2) attempt lethality. Method: Students ( N = 167) with a history of suicidality completed self-report measures assessing the lifetime worst-point ASAD episode and the presence of a lifetime suicide attempt, a clinical interview about attempt lethality, and a physical pain tolerance task. Results: Physical pain persistence was a significant moderator of the association between ASAD and lifetime suicide attempts ( B = 0.00001, SE = 0.000004, p = .032), such that the relationship between ASAD and suicide attempts strengthened at increasing levels of pain persistence. The interaction between ASAD and pain persistence in relation to attempt lethality was nonsignificant ( B = 0.000004, SE = 0.00001, p = .765). Limitations: This study included a cross-sectional/retrospective analysis of worst-point ASAD symptoms, current physical pain perception, and lifetime suicide attempts. Conclusion: ASAD may confer risk for suicidal behavior most strongly at higher levels of pain persistence, whereas ASAD and pain perception do not influence attempt lethality.

The Relationship

Parenting behaviors – specifically behaviors characterized by high control, intrusiveness, rejection, and overprotection – and effortful control have each been implicated in the development of anxiety pathology. However, little research has examined the protective role of effortful control in the relation between parenting and anxiety symptoms, specifically among adults. Thus, we sought to explore the unique and interactive effects of parenting and effortful control on anxiety among adults (N = 162). Results suggest that effortful control uniquely contributes to anxiety symptoms above and beyond that of any parenting behavior. Furthermore, effortful control acted as a moderator of the relationship between parental overprotection and anxiety, such that overprotection is associated with anxiety only in individuals with lower levels of effortful control. Implications for potential prevention and intervention efforts which specifically target effortful control are discussed. These findings underscore the importance of considering individual differences in self-regulatory abilities when examining associations between putative early-life risk factors, such as parenting, and anxiety symptoms.

The Way

Abstract. This paper aimed to assess whether differences in the way to conceive happiness, measured by the Orientations to Happiness measure, were associated with specific reactions to negative events. We hypothesized that among orientations to pleasure (portraying hedonism), to meaning (representing a eudaimonic approach to life), and to engagement (derived from the experience of flow), orientation to meaning would have displayed a stronger protective role against recent negative and potentially stressful events. After providing a validation of the Italian version of the Orientations to Happiness measure (Study 1), we performed regression analyses of the three orientations on positive and negative emotions linked to a self-relevant negative event (Study 2), and moderation analyses assessing the interactive effects of orientations to happiness and stressful events on well-being indicators (Study 3). Our findings supported the hypotheses. In Study 2, meaning was associated with positive emotions characterized by a lower activation (contentment and interest) compared to the positive emotions associated with pleasure (amusement, eagerness, and happiness). In Study 3, only meaning buffered the effect of recent potentially stressful events on satisfaction with life and positive affect. Results suggest that orientation to meaning might help individuals to better react to negative events.
