Specific and intraspecific classification ofSorghum species of the ser.Bicoloria (Snowd.) Ivanjuk. et Doron. and of the ser.Caffra (Snowd.) Ivanjuk. et Doron     

Dr. L. K. Ivanjukovich 《Genetic Resources and Crop Evolution》1981,29(1):273-286

Summary The intraspecific classification of cultivatedSorghum species of the ser.Bicoloria and ser.Caffra is discussed. The classification is based on studies or large living and herbarium collections as well as on the typical and authentic material; published monographs on the genus being made use of. In 8 cultivated species 70 varieties are considered, 8 of them were discovered for the first time. The data received contributed to enlarging the intraspecific systematics of a number of species presented inSnowden's monograph (1936).Parallelism in the evolution for a number of characters, i.e. homologous series, was discovered when intraspecific variability ofSorghum was investigated.The detailed study of the species and of the intraspecific taxons reveals new features of their affinity and differences and contributes to developing the phylogenetic system of the genus.As a result of the studies varieties were found out which would be of practical value for breeding work.

Spezies- und intraspezifische Klassifikation von Arten aus der ser.Bicoloria (Snowd.)Ivanjuk. etDoron. und der ser.Caffra (Snowd.)Ivanjuk. etDoron. der GattungSorghum Moench

Zusammenfassung Die intraspezifische Klassifikation kultivierterSorghum-Arten aus der ser.Bicoloria und der ser.Caffra wird diskutiert. Die Klassifikation basiert sowohl auf dem Studium umfangreicher lebender und Herbarium-Kollektionen als auch auf Typus- und Originalmaterial; publizierte Gattungsmonographien wurden genutzt. Bei 8 Kulturarten werden 70 Varietäten akzeptiert, von denen 8 zum ersten Mal gefunden wurden. Die erzielten Ergebnisse führten zu einer Erweiterung der intraspezifischen Systematik einer Anzahl der Arten, die inSnowden's Monographie (1936) aufgeführt sind.Parallelevolution für eine Anzahl von Merkmalen, d. h. homologe Reihen, wurde bei der Untersuchung der intraspezifischen Variabilität vonSorghum nachgewiesen.Die ausführliche Untersuchung der Arten und der intraspezifischen Taxa läßt neue Grundzüge ihrer Ähnlichkeiten bzw. Unterschiede erkennen und trägt zur Entwicklung des phylogenetischen Systems der Gattung bei.Im Ergebnis der Untersuchungen wurden Varietäten gefunden, die von praktischem Wert für die Züchtung sein können.

Problems ofPapaver somniferum-classification and some remarks on recently collected European poppy land-races     

Dr. Karl Hammer 《Genetic Resources and Crop Evolution》1981,29(1):287-296

Summary The principles of formal classification of cultivated plants are discussed with reference toPapaver somniferum. This species can be divided into 3 subspecies-the ancestral wild race ssp.setigerum (Dc.)Corb. and the two cultivated races ssp.somniferum and ssp.songaricum Basil. differing in geographical distribution and characters of the stigmatic lobes. In both of the cultivated races two convars are accepted on the basis of their indehiscent vs. shattering capsules. Varieties are defined according toDanert (1958) using seed- and flower-colours.Poppies, recently collected in parts of central Europe, are classified according to the proposed system. Unlike other crops, very variable land-races of poppies can still be found in this region. About 20 percent of the totally accepted varieties could be found, containing also races from ssp.songaricum and types with shattering capsules. The handling and maintaining of this material in the Gatersleben gene-bank is briefly discussed.

Probleme der Klassifikation vonPapaver somniferum und einige Bemerkungen zu unlängst gesammelten europäischen Mohn-Landsorten

Zusammenfassung Grundzüge der formalen Klassifikation von Kulturpflanzen unter besonderer Berücksichtigung vonPapaver somniferum werden diskutiert. Diese Art kann in drei Subspecies aufgegliedert werden — die wilde Ausgangssippe ssp.setigerum (DC.)Corb. und die beiden Kultursippen ssp.somniferum und ssp.songaricum Basil., die sich durch ihre geografische Verbreitung und Merkmale der Narbenscheiben voneinander abgrenzen lassen. In beiden Kultursippen werden je zwei Convarietäten unter Zugrundelegung ihres Schließ- bzw. Schüttmohncharakters unterschieden. Varietäten werden nachDanert (1958) anhand der Samen- und Blütenfarben definiert.Die in jüngster Zeit in einigen Teilen Zentraleuropas gesammelten Mohne werden nach dem vorgeschlagenen System klassifiziert. Im Gegensatz zu anderen Kulturpflanzen können in diesen Gebieten noch sehr variable Mohn-Landsorten gefunden werden. Ungefähr 20% der im System aufgeführten Varietäten konnten gesammelt werden, einschließlich einiger Vertreter der ssp.songaricum und von Schüttmohnsippen. Die Bearbeitung und Erhaltung dieses Materials in der Genbank Gatersleben wird kurz diskutiert.

New botanical variants ofTriticum sphaerococcum Perc. andTriticum spelta L. developed by hybridization of species from the genusAegilops L. withTriticum aestivum L     

Dr. Bogdan Bochev 《Genetic Resources and Crop Evolution》1981,29(1):361-367

Summary As a result of the hybridization ofAegilops ovata auct. non L. with theTriticum aestivum L. cultivar Bezostaja 1, new biological variants ofT. sphaerococ-cum Perc. have been obtained. Besides the basic morphological and biological characters, they possess also some new useful features, such as better expressed winter hardiness, resistance to fungal diseases, and higher content of protein. New botanical varieties ofT. spelta L. are a result of hybridization betweenAe. crassa Boiss. ssp.vavilovii Zhuk. (2n = 42) and different cultivars ofT. aestivum. Some of them have useful biological and agricultural characters and are considered to be of interest to further utilization in plant breeding. Thus, on the basis of all these results, new suggestions about the origin of the genusTriticum are made. At the same time, the new biological variants of both of these species increase the possibilities of their practical utilization in wheat breeding.

Neue botanische Varietäten vonTriticum sphaerococcum Perc. undTriticum spelta L. aus Kreuzungen von Arten der GattungAegilops L. mitTriticum aesti-vum L.

Zusammenfassung Durch Kreuzungen vonAegilops ovata auct. non L. mit der Sorte Bezostaja 1 vonTriticum aestivum L. wurden neue biologische Varianten vonT. sphaero-coccum Perc. erhalten. Neben den morphologischen und biologischen Merkmalen besitzen sie auch einige neue nützliche Eigenschaften, wie bessere Winterfestigkeit, Resistenz gegenüber Pilzkrankheiten, und einen höheren Proteingehalt. Neue botanische Varianten vonT. spelta L. sind Ergebnis von Kreuzungen zwischenAe. crassa Boiss. ssp.vavilovii Zhuk. (2n=42) und verschiedenen Sorten vonT. aestivum. Einige von ihnen weisen nützliche biologische und pflanzenbauliche Eigenschaften auf und können daher für eine künftige Anwendung in der Pflanzenzüchtung interessant sein. Auf der Grundlage dieser Ergebnisse werden neue Vermutungen über den Ursprung der GattungTriticum angestellt. Die neuen biologischen Varianten beider Arten erweitern die Möglichkeiten ihrer praktischen Nutzung in der Weizenzüchtung.

The Relationship Between Yield and Fructan Exo-Hydrolases Activity in Two Drought Resistant Wheat Cultivars Grown Under Different Fertilizer and Tillage Treatments     

Wei Chen  Sang-Soo Kwak  Anthony Egrinya Eneji 《Journal of plant nutrition》2015,38(1):13-27

Using two drought resistant wheat (Triticum aestivum L.) cultivars, ‘Changwu134’ and ‘Changhan58,’ a field experiment was conducted in ChangWu Agro-ecological Experiment Station on China's Loess Plateau during 2008 and 2009 to compare the effects of different fertilizer and tillage treatments on the fructan contents as well as fructan exo-hydrolase (FEH) activity in relation to wheat yield. We found that ‘Changhan58’ had greater yield and fructan content in the penultimate internode and higher FEH activity than did ‘Changwu134.’ For ‘Changhan58.’ applying 195 kg·ha^?1(120 +75) N plus 45000 kg·ha^?1 of pig manure and 120 kg·ha^?1 phosphate under conservation tillage produced the highest yield (6769 ka/ha), fructan content in penultimate internode, water use efficiency (WUE), as well as FEH activity among the fertilizer and tillage treatments. Therefore, routine soil management for wheat should focus on combined use of manures and inorganic fertilizer to enhance the amount and transportation efficiency of WSC and ultimately ensure greater yield.  相似文献

VERTEBRAL OSTEOSCLEROSIS IN A CAT SECONDARY TO RHABDOMYOSARCOMA     

Martha L.  Moon  DVM  MS Geoffrey K.  Saunders  DVM  MS Robert A.  Martin  DVM 《Veterinary radiology & ultrasound》1990,31(1):39-41

A 5–year–old cat was presented for pelvic limb weakness. Sclerosis of the vertebral body of T–10 was visible on thoracic radiographs. A compressive lesion at this area was noted on myelography. A tumor was partially removed at surgery, but the cat was killed because of poor postoperative response. Rhabdomyosarcoma was diagnosed at necropsy, with bone marrow necrosis and myelofibrosis, and new bone proliferation of the body of T–10. Causes of bone necrosis are discussed.  相似文献   

PSITTACINE SKULL RADIOGRAPHY     

J.R. Paul-Murphy    DVM  P.D. Koblik  DVM  MS  G. Stein  DVM  D.G. Penninck  DVM 《Veterinary radiology & ultrasound》1990,31(4):218-224

The psittacine skull is a complex anatomic structure, frequently traumatized but difficult to adequately image with standard radiographic procedures. Multiple views including a ventrodorsal, a lateral, and complementary oblique projections are necessary to fully evaluate potential skull fractures in the avian patient. Magnification radiography is a relatively easy procedure that aids the review of small osseous structures. Familiarity with psittacine skull anatomy greatly facilitates radiographic interpretation of cranial trauma.  相似文献   

EQUINE RENAL ULTRASONOGRAPHY: NORMAL AND ABNORMAL     

D.G. PENNINCK  DVM    H.M. EISENBERG  VMD DIPLOMATE ACVR  E.E. TEUSCHER  DVM    A. VRINS  DVM 《Veterinary radiology & ultrasound》1986,27(3):81-84

The kidneys of three clinically normal horses were evaluated ultrasonographically, utilizing a standardized approach. The normal renal architecture, including cortex, medulla, pyramids, renal sinus fat, collecting system, and intrarenal vessels, was evaluated.
A horse with hematuria was examined in the same manner and a mass was found in the right renal pelvis.
Ultrasonographic determinations were correlated with gross anatomy, clinical signs, and pathologic findings of a renal pelvic adenoma.  相似文献
