Groundnut is an annual legume and important oilseed crop in the world. In order to evaluate the influence of the topping height and application methods of Zinc (Zn) and Calcium (Ca) nano-chelates on quantitative and qualitative characteristics of groundnut, these experiments were carried out during the 2016–2017 cropping seasons on groundnut in Iran. Both foliar and in soil applications of Zn and Ca nano-chelates improved groundnut yield. Foliar application of Zn nano-chelate in combination with topping the main stem 20 cm above the ground produced the highest 100-seed weight (82.19 g), seed yield per unit area (2722.5 kg.h^?1), harvest index (57.53%), biological yield (6540.00 kg.h^?1), oil yield (1486.76 kg.h^?1), protein yield (742.66 kg.h^?1), seed Zn content (12.08 ppm) and Ca content (35.86 ppm). The application of Zn nano-chelate had different positive influences on vegetative and reproductive growth of groundnut plants. Generally, optimizing of the nutritional status in groundnut plants with Ca and Zn supplements is recommended to enhance the quantitative and qualitative yield of groundnut.  相似文献

本试验旨在研究春花生秧与夏花生秧的常规营养成分,并应用康奈尔净碳水化合物-蛋白质体系(CNCPS)评价其营养价值及其在奶牛瘤胃中降解特性的差异。采集河南地区春花生秧样品16个,夏花生秧样品28个,测定其干物质(DM)、粗蛋白质(CP)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)、粗脂肪(EE)、钙(Ca)、磷(P)、粗灰分(Ash)、酸性洗涤木质素(ADL)、淀粉、中性洗涤不溶氮(NDFIP)、酸性洗涤不溶氮(ADFIP)、非蛋白氮(NPN)、可溶性蛋白(SCP)含量及总能(GE)。选取3头装有永久性瘤胃瘘管的中国荷斯坦干奶牛,饲喂同一种全混合日粮(TMR),采取尼龙袋法测定花生秧的DM、CP、NDF和ADF在奶牛瘤胃中的72 h降解率,并计算其降解参数及有效降解率,应用CNCPS计算其碳水化合物和蛋白质组分,评定花生秧的营养价值。结果表明:1)春花生秧的CP、Ash、Ca、SCP含量极显著高于夏花生秧(P <0.01),NDF、ADF、ADL含量和GE极显著低于夏花生秧(P <0.01),P含量显著低于夏花生秧(P <0.05)。2)春花生秧的DM、CP、NDF、ADF有效有降解率显著高于夏花生秧(P <0.05)。3)春花生秧的快速降解真蛋白质(PB1)、中速降解真蛋白质(PB2)、快速降解碳水化合物(CA)、非结构性碳水化合物(NSC)含量极显著高于夏花生秧(P<0.01),NPN(PA)、碳水化合物、中速降解碳水化合物(CB2)含量显著低于夏花生秧(P<0.05),不可降解真蛋白质(PC)、不可降解碳水化合物(CC)含量极显著低于夏花生秧(P<0.01)。由此可见,春花生秧的营养价值优于夏花生秧,且瘤胃降解率均高于夏花生秧,其在瘤胃中的利用率较好,饲用价值更高。  相似文献   

Regulatory effects of reactive oxygen species on the production of PAI-1 in 3T3-L1 adipocytes and its related possible mechanisms     

CHEN Bao-ying  WEI Jing-guo  WANG Wei  XU Amin  WEI Long-xiao  CUI Guang-bin  YU Jun 《园艺学报》2009,25(6):1160-1164

AIM: To investigate the regulatory effects of reactive oxygen species (ROS) on the production of plasminogen activator inhibitor 1 (PAI-1), and try to determine the signaling cascades involved in it. METHODS: 3T3-L1 cells were cultured and differentiated into mature adipocytes. Cell viability was measured by MTT. The PAI-1 mRNA expression levels were evaluated by quantitative real-time PCR. Quantification of the PAI-1 protein levels secreted into conditioned medium was performed by multiplex immunoassay and sandwich ELISA. The phosphorylation status of protein kinases was determined by Bio-Plex phosphoprotein assays. RESULTS: In 3T3-L1 adipocytes, H2O2 significantly augmented the expression of PAI-1. Also, H2O2 activated several signaling pathways including ERK1/2, JNK, Akt, p70 S6K and JAK/STAT. Verified by protein kinase inhibitors, Akt, JAK/STAT and ERK1/2 may participate in the H2O2-induced increase in PAI-1. CONCLUSION: H2O2 markedly up-regulates the production of PAI-1 in 3T3-L1 adipocytes via some intracellular signaling pathways such as Akt, JAK/STAT and ERK1/2.  相似文献   

Cellular changes in the anterior pituitary of the domestic fowl during growth, sexual maturity and laying     

S O Amin  A B Gilbert 《British poultry science》1970,11(4):451-458

All the cell types in the hen's anterior pituitary varied in number during the period from 10 weeks to adulthood; there was often an associated change in apparent functional activity. The cells most affected were the gonadotrophs (both FSH and LH) and luteotrophs; changes in these cells were associated with the onset and maintenance of sexual maturity. Follicle‐stimulating hormone cells were the first to increase in number and activity and this was correlated with a general increase in steroid output from the ovary, as measured by the oviduct weight increase. With the onset of follicular maturation LH cells became obvious. Prolactin cells increased in number with the presumed general increase in circulating oestrogen. Acidophilic somatotrophs decreased with increasing age; thyrotrophs became more numerous about sexual maturity and it is thought that this reflects the general increase in metabolic rate which occurs at this time.  相似文献

African horsesickness virus was isolated from blood samples of street dogs in Aswan Province in Arab Republic of Egypt. Of six isolated "dog strain" African horsesickness viruses, three viruses designated D2, D6 and D10 have been identified as type 9 African horsesickness virus. Methods of isolation, tissue culture adaptation, serological indentification and typing are described. Horses experimentally infected with dog viruses showed febrile reaction and characteristic clinical and pathological signs of African horsesickness. Reisolation of African horsesickness virus type 9 was achieved from the horses during serial passages.  相似文献

Histological and immunohistochemical investigations of ovarian interstitial glands during non‐breeding season in camels (Camelus dromedarius)          下载免费PDF全文

MM Awad  RH Mohamed  YA Amin  HA Hussein 《Reproduction in domestic animals》2018,53(4):872-879

The aim of this was to investigate the histology and immunohistochemistry of interstitial glands during non‐breeding season in camel ovaries. A total of 21 mature, non‐pregnant and apparently healthy camels aged between 8 and 12 years were slaughtered. The ovaries were removed within 15 min, cleaned from adipose tissue, weighted and examined grossly. The histological preparation was made, and then, the blocks were cut at 3–5 microns thickness and stained by H&E for histological examinations. Moreover, some sections were stained with Sudan Black for lipid detection. Immunohistochemical analysis of paraffin‐embedded ovarian tissues was performed to detect the localization of S‐100, vimentin, progesterone receptors (PR) and oestrogen receptors (ER). Immunoreactive signals were detected using UltraVision Detection System. The results revealed that the interstitial glands were located in the cortical region and they were arranged in various arrangements either single, in couple or in groups rich in lipid droplet. All interstitial gland arrangements were enclosed by connective tissue capsules containing fibroblasts and collagenous fibres separated them from the surrounding ovarian structures. Both interstitial glands and their surrounding CT were penetrated by several blood vessels. There was a strong immunoreactive signal for S‐100 in the nuclei of interstitial cells, and no signals were detected either in cells of the interstitial glands or their connective tissue with PR. We could conclude that the interstitial gland is distinct in ovary of camel and further studies are needed to elucidate its rule in steroid synthesis.  相似文献   

Anesthetic Efficacy of Clove Oil,Propofol, 2‐Phenoxyethanol,and Ketamine Hydrochloride on Persian Sturgeon,Acipenser persicus,Juveniles          下载免费PDF全文

Anesthetics are commonly used in the aquaculture industry to reduce stress and prevent mortality of fish during transportation, handling, and surgical procedures. This study assessed the efficacy of four anesthetic agents (clove oil, propofol, 2‐phenoxyethanol [2‐PE], and ketamine hydrochloride) on Persian sturgeon, Acipenser persicus, juveniles. In addition, results of the first experiment were used to evaluate sedation concentrations suitable for transportation of Persian sturgeon. The concentrations of anesthetics or sedatives evaluated in the first experiment were: 25, 50, 75, and 100 mg/L for clove oil; 1, 1.25, 2.5, and 5 mg/L for propofol; 110, 330, 550, and 770 mg/L for 2‐PE; and 1250, 2500, 3750, and 5000 mg/L for ketamine hydrochloride. Results show significant reduction in time to anesthesia and significant increase in recovery time with increase in concentration of all anesthetics. The most clinically useful concentrations of anesthetics tested were between 25 and 50 mg/L for clove oil, less than 1 mg/L for propofol, 330 mg/L for 2‐PE, and none of the tested concentrations for ketamine hydrochloride. In the second experiment, juveniles were placed in low concentrations of anesthetic solutions for 24 h and survival assessed. The four anesthetics tested are suitable for light sedation during transportation of A. persicus juveniles. Results are helpful to scientists working with Persian sturgeon aquaculture and restocking programs.  相似文献   

The scaling technique in Palmer Drought Severity Index; generalized calibration and modification     

Tudeshki AR  Sichani SA  Nazemossadat SM  Karamouz M  Javanmard S 《Pakistan journal of biological sciences: PJBS》2008,11(5):702-710

The scaling technique in calculating Palmer Drought Severity Index (PDSI) has specific properties, which is considered in details, in this study. The Palmer scaling method contains a physically-based weighting factor called climatic characteristic coefficient, K. This factor, is the ratio of average moisture demand to average supply in a regional water balance, whose related coefficients and involved equation parameters should be calibrated according to any special case study. Therefore, in this study, the generalizing procedure of obtaining K-value with no dependency on particular area, in addition to some modifications in the process was analytically developed. The generalized procedure has an appropriate potential for various purposes such as; correctly identifying analytical K-formula, simplifying its application, recognizing its limitations and moreover it can be used in other researches for developing its advantages. The proposed procedure and its modifications also applied for a case study (e.g., Maharlue catchment, Fars province, Iran). The outputs of the application validated the suggested modifications; therefore, the obtained K-values can be used for other studies in the region.  相似文献
