Kuswantoro H, Ginting E, Utomo JS, Yusnawan E. 2019. Performance of agronomical and seed biochemical traits of soybean genotypes in relation to their tolerance to and preference by Nezara viridula. Biodiversitas 20: 356-363. Qualitative and quantitative variations of biochemical compounds in plant organs is one of the causes leading to infestation by a certain pest which prefers to feed on particular genotypes than other genotypes. Objectives of this study is to find out the relationship of selected agronomical features and seed biochemical contents of soybean genotypes with their tolerance to Nezara viridula and also the preference of N. viridula to these genotypes. A total of 50 soybean germplasm were grown at Muneng research station during the dry season of 2016. The variability of the tested germplasm was reflected in the diversity of agronomic characters and seed biochemical contents. There was a significant positive correlation among the studied seed biochemical parameters, namely protein, methionine and cysteine contents. The protein and cysteine contents did not relate to N. viridula preference, but it was related to soybean tolerance against N. viridula. It was indicated by the insignificant positive correlation of protein and cysteine contents with the number of unfilled pods and the negative correlation of protein and cysteine contents with the ratio of number of unfilled pods to the total number of pods. Methionine content increased N. viridula preference, but it had no effect on soybean tolerance. Five genotypes, namely MLGG 0164, MLGG 0195, MLGG 0103, MLGG 0896 and MLGG 0196 were selected based on high seed biochemical contents which can be used as gene sources in soybean breeding programs. Among these five genotypes, MLGG 0195 had high protein, methionine and cysteine contents, but it was not tolerant to N. viridula. Hence, this genotype should be cultivated by controlling N. viridula optimally. MLGG 0196 had the highest methionine content, relatively high cysteine content, and N. viridula tolerance. This genotype can be used to improve seed biochemical content and plant tolerance against N. viridula.

Abstract Background The etiology of reflux esophagitis (RE) is multi-factorial. This study analyzed the relationship of depression, anxiety, lifestyle and eating habits with RE and its severity and further explored the impact of anxiety and depression on patients’ symptoms and quality of life. Methods From September 2016 to February 2018, a total of 689 subjects at Xuanwu Hospital Capital Medical University participated in this survey. They were divided into the RE group (patients diagnosed with RE on gastroscopy, n = 361) and the control group (healthy individuals without heartburn, regurgitation and other gastrointestinal symptoms, n = 328). The survey included general demographic information, lifestyle habits, eating habits, comorbidities, current medications, the gastroesophageal reflux disease (GERD) questionnaire (GerdQ), the Patient Health Questionnaire-9 depression scale and the General Anxiety Disorder-7 anxiety scale. Results The mean age and sex ratio of the two groups were similar. Multivariate logistic regression analysis identified the following factors as related to the onset of RE (p < 0.05): low education level; drinking strong tea; preferences for sweets, noodles and acidic foods; sleeping on a low pillow; overeating; a short interval between dinner and sleep; anxiety; depression; constipation; history of hypertension; and use of oral calcium channel blockers. Ordinal logistic regression analysis revealed a positive correlation between sleeping on a low pillow and RE severity (p = 0.025). Depression had a positive correlation with the severity of symptoms (rs = 0.375, p < 0.001) and patients’ quality of life (rs = 0.306, p < 0.001), whereas anxiety showed no such association. Conclusions Many lifestyle factors and eating habits were correlated with the onset of RE. Notably, sleeping on a low pillow was positively correlated with RE severity, and depression was positively related to the severity of symptoms and patients’ quality of life.

Weightlifting is a discipline where technique and anthropometric characteristics are essential to achieve the best results in competitions. This study aims to analyse the relationships between body composition, limb length and barbell kinematics in the performance of weightlifters. It consists of an observational and descriptive study of 19 athletes (12 men [28.50 ± 6.37 years old; 84.58 ± 14.11 kg; 176.18 ± 6.85 cm] and 7 women [27.71 ± 6.34 years old; 64.41 ± 7.63 kg; 166.94 ± 4.11 cm]) who met the inclusion criteria. A level I anthropometrist took anthropometric measures according to the methodology of the International Society for the Advancement of Kinanthropometry (ISAK), and the measurement of the barbell velocity was made with the software Kinovea. In terms of body composition, both genders are within the percentage range of fat mass recommended for this sport. In female weightlifters, there is a positive correlation between foot length, maximal velocity in the Snatch (ρ = 0.775, p = 0.041), and performance indicator in the Snatch and the Clean & Jerk (ρ = 0.964, p < 0.001; ρ = 0.883, p = 0.008, respectively). In male weightlifters, a positive correlation between tibial length and average velocity of the barbell in the Snatch is observed (ρ = 0.848, p < 0.001). Muscle mass percentage correlates positively with performance indicator in both techniques (ρ = 0.634, p = 0.027; ρ = 0.720, p = 0.008). Also, the relative length of the upper limb is negatively correlated with the performance indicator (ρ = −0.602, p = 0.038). Anthropometry and body composition may facilitate skill acquisition among this sport population, contributing to increase the limited body of scientific knowledge related to weightlifting.

HighlightsThe relationship of vibration and header loss was studied by multi-point vibration measurement and loss collection test.There was an approximately linear positive correlation between total header vibration and total rapeseed header loss.The header frame was analyzed and optimized through modal simulation and testing.The total rapeseed header loss of the improved header was reduced by 33.2% to 46.9%.Abstract. In view of the current large rapeseed header losses of rape combine harvesters, the effects of the header on rapeseed header loss were studied from the perspective of vibration. First, the vibrations at various measuring points on the header during rape harvest were studied using a data acquisition and analysis system while performing collection tests of rapeseed header loss with the sample slot method. The relationships between total header vibration and total rapeseed header loss and between vertical cutter vibration and rapeseed vertical cutter loss were shown to have a positive correlation, and they all increased with the increase in engine speed. Vertical cutter loss accounted for 31.2% to 42.4% of the total rapeseed header loss. Modal analysis and optimization of the header frame were then performed by simulation and test. The natural frequencies of the first-order and second-order modes of the optimized header were increased, and the possibility of resonance with other working parts was eliminated. Finally, the improved header was tested during rape harvest. The results showed that the total vibration of the improved header was reduced by 19.9% to 43.9%, and the total rapeseed header loss was reduced by 33.2% to 46.9%. The vertical cutter vibration was reduced by 30.5% to 49.8%, and the rapeseed vertical cutter loss was reduced by 20.8% to 34.7%. In addition, the vibration and rapeseed loss of the improved header had relatively slow rates of increase with the increase in engine speed. The method of reducing rapeseed loss by reducing the header vibration achieved an obvious and positive effect.

The study was carried out to determine length-weight relationship and sex ratio of a freshwater fish Amblypharyngodon mola (Hamilton 1822) collected from Dekar haor of Sunamganj district during the period of January to August 2017. A total of 2000 fishes were collected for the study and categorized these fishes into three groups namely males, females and combined sexes. Among 2000 mola 777 were male and 1223 were female. Length-weight equations and the correlation coefficients obtained for males, females and combined ones were: males Y = –1.97 + 3.00X, r = 0.883; females Y = –2.30 + 3.41X, r = 0.914 and combined Y = –2.11 + 3.16X, r = 0.904. Female’s A. mola attained more weight with the increases in length. Value of correlation coefficient ‘r’ was 0.883 for male and exhibited highly positive correlation between length and weight. On the contrary, ‘r’ value for female was 0.914 and it had also strongly positive correlation between length and weight relationships. Length-weight relationship of A. mola for male, female and combined sexes showed allometric pattern of growth. Condition factor ‘K’ for male, female and combined sexes was 1.09, 1.05 and 1.06, respectively and indicated better condition of fishes. The highest sex ratio (1 : 2.05) was found in May and the lowest (1 : 1.33) was in February. Dominance of females over males throughout the year was observed with an average ratio of male and female 1 : 1.57. Therefore, results of the study indicate that the existing hydrobiological conditions of the haor are conducive for food availability, free movement, feeding and better growth of the fish. Asiat.

AbstractThe biology of Telenomus chloropus Thomson was studied on eggs of Nezara viridula (L.) which had been reared on the stink bug resistant soybean, Glycine max (L.) Merrill, genotype PI 171444 and the susceptible cultivar Davis. Time of development of T. chtoropus from egg to adult emergence was not significantly different in eggs oviposited by N. viridula reared on either Davis or PI 171444. However, successful emergence of T. chloropus from host eggs was significantly lower for parasitoids that developed in eggs from N. viridula reared on PI 171444. Longevity of adult T. chloropus was not significantly different between females that were allowed or denied oviposition regardless of the genotype fed the host. Total fecundity of T. chloropus reared from eggs of N. viridula fed PI 171444 was one-half that of parasitoids from the Davis treatment. Although ovipositional patterns over the lifetime of parasitoids from the 2 treatments were similar, the mean number of progeny produced per day was significantly greater in the Davis treatment. Also, the ovipositional period of parasitoids from the PI 171444 treatment was shorter than for parasitoids from the Davis treatment.
