A field experiment was conducted at Spices Research Sub-Centre (SRSC), Bangladesh Agricultural Research Institute (BARI), Faridpur, Bangladesh during the winter season of 2018-2019 to investigate the influences of transplanting times of seedlings and the varieties on the yield and quality of onion bulbs. There were six levels of transplanting time such as T1: November 15, T2: November 30, T3: December 15, T4: December 30, T5: January 14 and T6: January 29 under the trial. The varieties used in the study were: BARI Onion-1 and BARI Onion-4. The experiment was laid out in a randomized complete block design (RCBD) of factorial concept with three replications. The results revealed that dates of transplanting, varieties and their combined effects had significant effect on the parameters studied with minor exception. The plant height, number of leaves/plant and incidence of bolting were decreased with the passage of transplanting time. The maximum values (54.51 cm, 8.53 and 71.28%) of the aforementioned traits were recorded at early transplanting on November 15, respectively. The reduced percent of bolting (2.22%) was observed at December 30. While no incidence of bolting was found under transplanting on 14-29 January. Bulb diameter, individual bulb weight, yield, total soluble solid content and dry matter content of bulb were increased up to transplanting on December 15. Afterwards the values of aforesaid parameters were gradually decreased. The highest yield (17.65 t/ha), total soluble solid content (17.02 0brix) and dry matter content of bulb (15.95%) were obtained from December 15 insignificantly followed by December 30 (16.30 t/ha). The delayed transplanting on 29 January markedly reduced the yield (6.72 t/ha), total soluble solid content (12.58 0brix) and dry matter content of bulb (11.61%) as well. The variety BARI Onion-4 performed better in respect of yield and yield attributes but it showed inferior quality. The combined effect of December 15 x BARI Onion-4 gave the highest yield attributes and yield of onion followed by the combination of November 30 x BARI Onion-4 and December 30 x BARI Onion-4 while the values among the three treatments were statistically similar.

Background: Phospholipase D (PLD)is closely related to browning and senescence of postharvest longan fruit. Objective: This study investigated the effects of 2-butanol (a PLD inhibitor) on the expression and regulation of PLD during storage of longan fruit at a low temperature. Methods: Senescence-related quality indices showed that the 2-butanol-treated fruit presented lower pericarp browning index, pulp breakdown index and total soluble solid value than the untreated fruit. Results: The fruit treated by 60 µL/L 2-butanol exhibited the strongest inhibition on senescence, which significantly delayed changes in weight, titratable acidity content, total soluble solid content and ascorbic acid content. This treatment maintained a high level of total phenolic content and caused significant inhibition on pericarp browning and pulp breakdown. Through ELISA method, 60 µL/L 2-butanol treatment also reduced PLD activity. Real-time RT-PCR (RT-qPCR) results showed that PLD mRNA expression level was inhibited by 60 µL/L 2-butanol within 15 days. Western-blotting results further confirmed the differential expression of PLD during storage, and a relatively higher expression for PLD protein was found in control compared to the 2-butanoltreated fruit during 15-d storage. Conclusion: These results provided a scientific basis and reference to further investigating postharvest longan quality maintenance by regulating the PLD gene expression.

Abstract This article presents a method to combine QTL results from different independent analyses. This method provides a modified Akaike criterion that can be used to decide how many QTL are actually represented by the QTL detected in different experiments. This criterion is computed to choose between models with one, two, three, etc., QTL. Simulations are carried out to investigate the quality of the model obtained with this method in various situations. It appears that the method allows the length of the confidence interval of QTL location to be consistently reduced when there are only very few “actual” QTL locations. An application of the method is given using data from the maize database available online at http://www.agron.missouri.edu/.

Objective: To systematically review the effectiveness of electromyographic biofeedback interventions to improve pain and function of patients with shoulder pain. Design: Systematic review of controlled clinical trials. Literature search: Databases (Medline, EMBASE, CINAHL, PEDro, CENTRAL, Web of Science, and SCOPUS) were searched in December 2020. Study selection criteria: Randomized clinical trials that investigated the effects of electromyographic biofeedback for individuals with shoulder pain. Patient-reported pain and functional outcomes were collected and synthesized. Data synthesis: The level of evidence was synthesized using GRADE and Standardized Mean Differences and 95% confidence interval were calculated using a random-effects inverse variance model for meta-analysis. Results: Five studies were included with a total sample of 272 individuals with shoulder pain. Very-low quality of evidence indicated that electromyographic biofeedback was not superior to control for reducing shoulder pain (standardized mean differences = −0.21, 95% confidence interval: −0.67 to 0.24, P = 0.36). Very-low quality of evidence indicated that electromyographic biofeedback interventions were not superior to control for improving shoulder function (standardized mean differences = −0.11, 95% confidence interval: −0.41 to 0.19, P = 0.48). Conclusion: Electromyographic biofeedback may be not effective for improving shoulder pain and function. However, the limited number of included studies and very low quality of evidence does not support a definitive recommendation about the effectiveness of electromyographic biofeedback to treat individuals with shoulder pain.
