组培技术在生产上的最大应用就是进行加繁。许多研究人员已经报道过甘蔗的离体繁殖(Prasad Chaturvedi，1992和Dhumale等人，1994)。繁殖率因品种而异，也与生长调节剂的不同含量有关(Nikhade和Raut，1993，Patel等人，2001)。拉胡里生物技术中心正在对三个甘蔗品种进行离体繁殖，以便通过糖厂苗圃向蔗农提供甘蔗种植纯种。  相似文献   

Preliminary studies on combiners and combinations for quality traits in tomato (Lycopersicon esculentum Mill.)     

A. A. Patil  S. S. Patil 《Plant foods for human nutrition (Dordrecht, Netherlands)》1988,38(1):43-49

Line×Tester analysis of 2 testers and 10 lines was conducted for fruit quality characters. Though both general (gca) and specific combining ability (sca) variances contributed significantly for these traits, the contribution of sca variance was more prominent for titratable acidity, total soluble solids and ascorbic acid content, while for pericarp thickness gca variance was more important. The highest gca effects for pericarp thickness, total soluble solids, ascorbic acid content and titratable acidity were recorded by the lines SM, Sioux, TT and SW 72, respectively. Based on pooled gca score, SW 72 was recognised as a good combiner for quality traits. The magnitude and significance of sca effects varied with the characters. Two superior crosses were identified and the implication of combining ability effects on handling these crosses are discussed.  相似文献   

Rapid diagnosis of tuberculosis in dromedary camel (Camelus dromedarius) using lateral flow assay-based kit     

Ranjan  Rakesh  Narnaware  Shirish D.  Nath  Kashi  Sawal  R. K.  Patil  N. V. 《Tropical animal health and production》2018,50(4):907-910

Accurate early antemortem diagnosis of tuberculosis in dromedary camels is difficult due to the lack of reliable diagnostic test. The present study aimed to evaluate a lateral flow assay-based kit (rapid assay kit) in tuberculosis diagnosis that employs immuno-chromatographic detection of antibodies in serum, plasma, or whole blood. In a dromedary camel herd comprising 337 animals located at Bikaner, Rajasthan, India, 50 adult weak camels (11 males and 39 females) were tested by applying a single intradermal tuberculin test (SIDT) and rapid assay kit. A total of 14 animals (2 males, 12 females) were found positive in rapid assay. In SIDT, four animals revealed a positive reaction in the neck region and seven animals in the tail base. Another male animal was found SIDT positive but negative in rapid assay; it died after 12 months. Nine rapid assay positive animals died asymptomatically in 1- to 11-month period revealing postmortem tuberculosis lesions that were confirmed by Ziehl-Neelsen staining and histopathology. No tuberculous lesion was evident in the animal found positive in SIDT alone. Results of the present study indicated that serological tests like rapid assay kit can serve as a reliable test for antemortem diagnosis of tuberculosis in dromedary camel.

Variability in pod and seed traits of <Emphasis Type="Italic">Pongamia pinnata</Emphasis> Pierre ecotypes in North Karnataka,India     

Vinod Kumar Patil  G. R. Naik 《林业研究》2016,27(3):557-567

An evaluation of 30 naturally available candidate-plus trees (CPTs) of Pongamia pinnata was carried out to elucidate the genetic variability and relationship of pod and seed traits and progeny growth traits to select the best planting material with higher productivity. Significant variations were observed in pod and seed characteristics, oil content, and during the progeny trial studies. The highest values were found in 100-pod weight (410.4 gm) and 100-seed weight (195.92 gm) and the phenotypic and genotypic variance was found maximum in 100 pod weight (4364.71 and 4289.93) and 100 seed weight (813.8 and 768.93), respectively. Estimates of the phenotypic coefficient of variance were higher than the genotypic coefficient of variance for all the pod and seed traits and progeny growth traits, which depict the predominant role of the environment. Approximately 99 % of broad-sense heritability was revealed in oil content, followed by 100-pod weight (98.28 %), and canopy growth (96.93 %). Pod thickness shows the highest genetic advance of 56.61 %, followed by pod width (53.43 %) and canopy growth (49.3 %). Pod and seed traits have proven a positive correlation between each other and with progeny growth traits, except a few negative values. Hierarchical clustering by Ward’s minimum variance cluster analysis showed phylogeographical patterns of genetic diversity. K-means clustering revealed that trees from different geographical regions were grouped together in a cluster where as trees from the same geographical area are placed in a different cluster. Seven Pongamia ecotypes (GRP-8, 9, 13, 14, 18, 28, and 29) are found superior in traits, namely 100-pod weight, 100-seed weight, oil content, germination rate, plant height, canopy growth, and collar diameter. The traits 100-pod weight and 100-seed weight are highly correlated with the progeny growth traits and even have higher heritability and genetic advantages.  相似文献   

Supercritical fluid extraction of limonoid glucosides from grapefruit molasses     

Yu J  Dandekar DV  Toledo RT  Singh RK  Patil BS 《Journal of agricultural and food chemistry》2006,54(16):6041-6045

Limonoid glucosides (primarily limonin 17-beta-D-glucopyranoside, LG) were extracted from grapefruit molasses by supercritical fluid extraction using a supercritical carbon dioxide-ethanol (SC CO(2)-ethanol) system. Extraction conditions to maximize the yield of LG were determined by varying pressure, temperature, ethanol concentration, and extraction time. The highest yield of LG at 0.61 mg/g molasses was obtained at a pressure 48.3 MPa, a temperature of 50 degrees C, 10% ethanol (X(Eth) = 0.1), and 40 min of extraction time at a flow rate of 5.0 L/min. The results demonstrated that SC CO(2) extraction of limonoid glucosides from grapefruit molasses has practical significance for commercial production.  相似文献   

Evaluation of ergonomic risk factors among veterinary ultrasonographers     

Randall E  Hansen C  Gilkey D  Patil A  Bachand A  Rosecrance J  Douphrate D 《Veterinary radiology & ultrasound》2012,53(4):459-464

Between 65% and 91% of human‐patient sonographers report musculoskeletal symptoms related to their work activities. Ergonomic risk factors associated with musculoskeletal symptoms and musculoskeletal disorders (MSDs) include force, repetition, and awkward postures of the upper extremities. We hypothesized that veterinary sonographers experience similar risk factor exposures as their colleagues in human‐patient sonography, and that work‐related exposures may lead to similar prevalence of musculoskeletal symptoms and disorders. The Occupational Safety and Health Administration and Society of Diagnostic Medical Sonography published MSD prevention guidelines in 2003. Similar guidance for sonographers examining animal patients does not exist. This cross‐sectional study was designed to evaluate the prevalence of musculoskeletal symptoms among veterinary sonographers and identify reported risk factors. A 59‐item survey questionnaire was administered via email to veterinary specialists likely to perform ultrasound. Musculoskeletal pain related to performing ultrasound exams was reported by 62% of the respondents. Musculoskeletal symptoms were significantly associated with female gender (odds ratio [OR], 4.55; 95% confidence interval [CI], 2.04–10.19), age (OR, 1.06; 95% CI, 1.01, 1.10), previous work‐related trauma (OR, 6.86; 95% CI, 1.71, 27.40), not consistently using a normal height chair (OR, 2.63; 95% CI, 1.19, 5.80), and 15°–45° abduction of shoulder (OR, 2.34; 95% CI, 1.11, 4.92) . It was concluded that the prevalence of musculoskeletal symptoms among veterinary sonographers was similar to that occurring in human‐patient sonographers. © 2012 Veterinary Radiology & Ultrasound.  相似文献   

Efficient Purification of Heavy-Metal-Contaminated Water by Microalgae-Activated Pine Bark     

Elena Lourie  Vishwanath Patil  Elin Gjengedal 《Water, air, and soil pollution》2010,210(1-4):493-500

Batch experiments were performed to study metal sorption by pine bark and algae-treated bark. The biosorption of copper (Cu), lead (Pb), zinc (Zn), cadmium (Cd), cobalt (Co), and nickel (Ni) in synthetic multimetal aqueous solutions was studied as a function of metal content in solution, and amount and size of bark particles used for sorption. Influence of water hardness (Ca²⁺ only was tested) on the metal sorption process was also evaluated. Metal uptake from solutions with high heavy metal content (i.e. 10× the limit for leachate from landfills) was found to be independent of Ca²⁺ concentration. At low metal content in solution (i.e. 1× the limit for leachate from landfills), uptake of Cu, Zn, Ni, and Cd decreased with increasing Ca²⁺ content in water. Microalgae-treated bark was found to increase the metal sorption efficiency. Air-drying of bark-entrapped algae was shown to be the best method for sorbent drying. In general, the green algae, Chlorella sp. and Pseudokirchneriella subcapitata showed the best results in metal uptake. Sorption of Co, Zn, Ni, and Cd from solution with high levels of both heavy metals and calcium increased by almost 50% with algae treatment of bark was applied. At low levels of metals and calcium content, 100% uptake of Cu and Pb in water was observed. Uptake of other metals from solution with low metal and Ca content was relatively high (50–60%). Low pH (pH 3.0) had no influence on metal sorption from solutions with high metal content. For solutions with low metal content a decrease of metal uptake by 10–15% was observed for all the metals but Pb. Thus, the treatment of bark with microalgae was successful and influenced positively the uptake capacity of the bark.  相似文献   

Degradation rates in soil of 1-benzyltriazoies and two triazole fungicides     

Shantagouda G. Patil  Peter H. Nicholls  Keith Chamberlain  Geoffrey G. Briggs  Richard H. Bromilow 《Pest management science》1988,22(4):333-342

The degradation rates in soil of 1-benzyltriazole together with six analogues having substituents in the phenyl ring and two commercial triazole fungicides, PP450 and triadimefon, were determined at 15°C and 20 % soil water content. The order of degradation rates of the benzyltriazoles was H > 4-OCH₃ > 4-F>4-Cl.4-≥tert-C₄H_g3,4-diCl>3-CF₃. Thus, in general, persistence was enhanced by electron-withdrawing substituents and by lipophilic groups that increased sorption by soil. Of the commercial fungicides, PP450 was degraded very slowly (half-life 578 days) while triadimefon was quickly converted (half-life 15 days) to the corresponding alcohol, triadimenol, which in turn was degraded very slowly. The effects of temperature and soil water content on rate of degradation were studied for 1-benzyltriazole and 1-(4-fluorobenzyl)triazole. The rate of degradation of 1-benzyltriazole was more sensitive to soil temperature and water content than was that of 1 -(4-fluorobenzyl)triazole. The influence of these results on the input data required by models which simulate persistence in field soil is discussed.  相似文献
