Relationship between the change of starch and sucrose contents in flag leaf and the grain dry matter accumulation during heading and grain filling in hybrid rice

Shiguang Li Lianyuan Luo Jun Duan Liang Chengye

With the hybrid rice Weiyou 64 and W6154s×Teqing, the relationship between the changes of starch and sucrose levels in flag leaf and the dry matter accumulation of grains was studied. Sucrose content in flag leaf of the two combinations increased rapidly from 5 to 15 days after heading, which significantly paralleled with the increase of the dry matter accumulation and sucrose content in the grains of the upper part of panicle during the same period. Starch content in flag leaf decreased significantly from 5 to 10 days after heading. Most of the upper grains in panicles ceased to accumulate dry matter and reach plumpness after 20 days of heading. These results suggested that during the filling of upper grains in the combinations the relationship between the sink and the source was balanced and coordinated well. The dry matter of most of the lower grains in panicles was still accumulated slowly after 20 days of heading, and the average weight of lower grains was significantly less than that of the upper grains after ripening. Sucrose level in flag leaf declined fast, while starch level changed less after 20 days of heading, which suggested that the capacity for synthesizing and....

Study of metabolism characteristics of lactic energy system in 100?m race

Shiguang Li

The blood lactate of 30 students of physical education of different level were tested (after) 100?m race and repeated runs of various short distance. It was found that accumulation of blood lactate after 100?m race in subjects of different level in varying degrees and the training level of the subjects remarkably affected the tested blood lactate values. With the gradual increase of the distance of the races,there was a stage of rapid rising in blood lactate values after different (distance) of repeated runs,and therefore tactic energy system plays an important part in 100?m race.

Biological characteristics and fumigation technology for Heterobostrychus hamatipennis Lesne

Anhui Nongye Daxue xuebao (2013)

Yujie He Qinglin Chen Lin Huafeng Maoye Li Yumei Zhang

Heterobostrychus hamatipennis Lesne causes more and more serious damage on the wicker in warehouse in Anhui province in recent years.In order to control it efficiently,we studied its biological characteristics and fumigation technology.The results of feeding in the laboratory and survey in the warehouse were as follows.It has 2 generations a year in Anhui province and overwinter as matured larvae in the injured wickers.The overwintering larvae begin to harm in late March and pupate in late April.A large number of the adults emerge in the middle of May.The adults start to spawn in late May.The larvae of the first generation hatch in early June.The larvae start to pupate in early August.In the middle of August,the first generation adults emerge.About ten days later,the adults start to spawn.In early September,the second generation larvae hatch.And until November,when the new wickers are harvested,the matured larvae would move into the new wickers and overwinter.The fumigation tests were carried out with aluminium phosphide 56% tablet and dichlorvos 80% emulsion in hermetic bags,and the results showed that the mortality in different stages could achieve 100% at 72 h after fumigation with aluminum phosphide 56% tablet at the dose of 12 g.m-3,and the larvae are more sensitive to phosphine than any other stages.Therefore,fumigation control must focus on the stage of recovery of overwintering generation larvae,which is in late March and early April every year,with aluminium phosphide 56% tablet at 12 g.m-3above 72 h.

Aphicidal Activity ofIllicium verumFruit Extracts and Their Effects on the Acetylcholinesterase and Glutathione S-transferases Activities inMyzus persicae(Hemiptera: Aphididae)

Journal of Insect Science (2016)

Benguo Zhou Sa Wang Tingting Dou Su Liu Mao‐Ye Li

This study aims to explore the aphicidal activity and underlying mechanism of Illicium verum Hook. f. that is used as both food and medicine. The contact toxicity of the extracts from I. verum fruit with methyl alcohol (MA), ethyl acetate (EA), and petroleum ether (PE) against Myzus persicae (Sulzer), and the activities of acetylcholinesterase (AChE) and glutathione S-transferases (GSTs) of M. persicae after contact treatment were tested. The results showed that MA, EA, and PE extracts of 1.000 mg/l caused, respectively, M. persicae mortalities of 68.93%, 89.95% and 74.46%, and the LC50 of MA, EA, and PE extracts were 0.31, 0.14 and 0.27 mg/l at 72 h after treatment, respectively; the activities of AChE and GSTs in M. persicae were obviously inhibited by the three extracts, as compared with the control, with strong dose and time-dependent effects, the inhibition rates on the whole reached more than 50.00% at the concentration of 1.000 mg/l at 72 h after treatment. The inhibition of the extracts on AChE and GSTs activities (EA extract > PE extract > MA extract) were correlated with theirs contact toxic effects, so it is inferred that the decline of the metabolic enzymes activities may be one of important reasons of M. persicae death. The study results suggested that I. verum extracts have potential as a eco-friendly biopesticide in integrated pest management against M. persicae.

Biological characteristics of Metarhizium anisopliae var. major and its virulence to white grubs

Journal of Applied Ecology (2006)

Huafeng Lin Shiguang Li Lei Zhang Pingli Wang Yiwen Zhou

With Beauveria brongniartii and Metarhizium anisopliae var. anisopliae as the reference, this paper studied the biological characteristics and invading ability of Metarhizium anisopliae var. major, a new variety separated from white grubs. The results showed that the optimal culture condition of M. anisopliae var. major was similar with that of other entomopathogenic species, and the optimal temperature was 25 degrees C. Among the three test media, PPDA was the most appropriate one, followed by SDAY and Czapek. M. anisopliae var. major had a stronger virulence than B. brongniartii at lower temperature, with an accumulative mortality of white grubs being 88.23% and 76.47%, respectively, after treated with soil and through spraying, suggesting that M. anisopliae var. major had a good prospect to widely apply in field.

Maternal and neonatal complications after IVF/ICSI-fresh embryo transfer in low-prognosis women under the POSEIDON criteria: a retrospective cohort study

BMC Pregnancy and Childbirth (2023)

Shiguang Li Huifang Tan Huimin Fu Juan Du Peihao Liu

Abstract Background Several studies on pregnancy complications of poor ovarian response (POR) patients did not draw a consistent conclusion. The POSEIDON criteria introduces the concept of “low prognosis” and divides POR patients into four groups based on age, AFC and AMH for individualized management. We analyzed low-prognosis population and patients with regular ovarian response, compared maternal and neonatal complications and discussed the relevant risk factors. Methods A retrospective cohort study was conducted of females who achieved a singleton clinical pregnancy after IVF / ICSI—fresh embryo transfer in a single center from January 2014 to March 2019. Participants with low prognosis, as defined by the POSEIDON criteria, were enrolled in the study groups. The controls were defined as AFC ≥ five and number of retrieved oocytes > nine. Maternal and neonatal complications were compared among those groups. Results There were 2554 cycles in POSEIDON group 1, 971 in POSEIDON group 2, 141 in POSEIDON group 3, 142 in POSEIDON group 4, and 3820 in Control. Univariate analysis roughly showed that Groups 2 and 4 had an increased tendency of pregnancy complications. Multi-variable generalized estimating equations (GEE) analysis showed that the risks of GDM, total pregnancy loss, and first-trimester pregnancy loss in Groups 2 and 4 were significantly higher than in Control. The risk of hypertensive disorders of pregnancy (HDP) in Groups 2 and 3 increased, and Group 4 had an increased tendency without statistical significance. After classification by age, GEE analysis showed no significant difference in risks of all complications among groups ≥ 35 years. In patients < 35 years, the risk of HDP in POSEIDON group 3 was significantly higher than in controls (< 35 years), and there was no significant increase in the risk of other complications. Conclusion Compared to patients with regular ovarian response, low-prognosis population have increased tendency of maternal and neonatal complications. In low-prognosis patients, advanced age (≥ 35 years) might be the predominant risk factor for pregnancy complications. In those < 35 years, poor ovarian reserve could contribute to HDP.
