Die submontanen krautreichen Buchenwälder auf Silikatböden in der westlichen Tschechoslowakei (Tschechische Sozialistische Republik) zerfallen in vier Assoziationen: 1.Tilio cordatae-Fagetum Mráz 1960 em.Moravec 1977, 2.Tilio platyphylli-Fagetum Klika 1939, 3.Melico-Fagetum Seibert 1954 und 4.Carici pilosae-Fagetum Oberdorfer 1957. DasTilio cordatae-Fagetum ist an niedrigere Bergländer Mittel-, Süd- und Westböhmens gebunden. DasTilio platyphylli-Fagetum ist eine lokal bedingte Assoziation des Westteils des Gebirges ?eské st?edoho?í. DasMelico-Fagetum kommt in Nord- bis Ostböhmen und Nord- und Mittelmähren vor. DasCarici pilosae-Fagetum ist auf die Karpaten beschränkt (ausnahmsweise greift es auf den Ostrand des Böhmischen Hochlandes über). Die Buchenwälder des Hügellandes bei Jevany (Mittelböhmen) und des Gebirges ?elezné hory gehören, trotz dem Vorkommen in submontanen Lagen, demDentario enneaphylli-Fagetum Oberdorfer ex W. etA. Matuszkiewicz 1960 an. Die Zusammensetzung der Assoziationen ist durch pflanzensoziologische Tabellen belegt und ihre Verbreitung auf einer Punktkarte erfasst. 相似文献

1. The oligomeric dicyclohexylcarbodiimide (DCCD)-binding protein of mitochondrial ATPase was studied using (a) the relationship between [14C]DCCD binding and inhibition of ATPase activities and (b) the analysis of the kinetics of inhibition. 2. The [14C]DCCD binding to bovine heart mitochondria is linearly proportional to the inhibition of ATP hydrolysis up to a 50% decrease of the original activity resulting in 0.6 mol DCCD bound covalently to the specific inhibitory site (Hous?t?k, J., Svoboda, P., Kopecký, J., Kuz?ela, S?. and Drahota, Z. (1981) Biochim. Biophys. Acta 634, 331–339) per mol of the fully inhibited enzyme. 3. Kinetics of the inhibition of both the ATPase activity (heart and liver mitochondria) and ADP-stimulated respiration (liver) reveal that 1 mol DCCD per mol ATPase eliminates both the synthetic and the hydrolytic activities. It is inferred that the activity-binding correlation underestimates the number of DCCD-reactive sites. 4. The second-order rate constant of the DCCD-ATPase interaction (k) is inversely related to the concentration of membranes, indicating that DCCD reaches the inhibitory site by concentrating in the hydrophobic (phospholipid) environment. 5. At a given concentration of liver mitochondria, comparable k values are obtained both for the inhibition of ATP hydrolysis (k=5.35·102M?1·min?1) and ADP-stimulated respiration (k=5.67·102M?1·min?1). 6. It is concluded that both the synthetic and the hydrolytic functions of ATPase are inhibited via a common single DCCD-reactive site. This site is represented by one of the several polypeptide chains forming the oligomer of the DCCD-binding protein. The inhibitor-ATPase interaction does not exhibit cooperativity, indicating that the preferential reactivity towards DCCD is an inherent property of the inhibitory site. 相似文献

Aminoethoxyvinylglycine (AVG) applied as a droplet (3 l, 0.1 mM) to the plumule of seedlings of both the short-day plantChenopodium rubrum and the long-day plantChenopodium murale counteracted to a great extent or even canceled the inhibition of flowering due to exogenous indole-3-acetic acid (IAA). This effect was more pronounced with the two substances administered simultaneously than with later application of AVG alone. AVG by itself in some cases promoted the percentage of flowering in bothChenopodium species. Application of IAA to the shoot apex was shown to elevate ethylene production in both species, whereas application of AVG alone was shown to suppress it. Thus, ethylene may be considered an active agent of flowering inhibition brought about by IAA application. 相似文献

Following the “Index of new names” (Theurillat etMoravec 1991a), the present work collects the names of syntaxa (in the sense of the Code of Phytosociological Nomenclature,Barkman et al. 1986) above subassociation rank typified in 1989. The list comprises 110 names of syntaxa. 相似文献

Penicillium cyclopium growing in a surface culture with 2-ketoglutarate or glutamate as a sole carbon source produced ethylene in two phases. The first peak of ethylene production (EP 1) was associated with aerial mycelium growth whereas the second peak of ethylene production (EP 2) occurred with formation and maturation of conidia. Conidiation was induced by blue light between 120 and 172 h after the culture was started and depended on the presence of a carbon source at the stage of conidiophore initiation. Exogenous phosphate content dropper rapidly before the onset of conidiation. The EP 2 was connected with conidiation via this drop. Addition of phosphate prior to the conidiophore initiation and during conidiation inhibited EP 2 without affecting conidiation, but conidia lacked a green pigment and their germination ability decreased by 905. Exogenous ethylene did not restore normal development. The EP 2 in asporogenic cultures was evoked by incubation in the dark and by phosphate removal. The EP 2 and conidiation were accompanied by an increased oxygen consumption. The EP 1 yield of ethylene depended only on biomass growth and was unaffected by any treatment mentioned above. 相似文献

A mathematical model of the batch cultivation of Claviceps purpurea was formulated. The main attention was devoted to the effect of exocellular and intracellular phosphate on the growth of the mycelium and production of clavine alkaloid under experimental conditions without limitation by carbon and nitrogen sources. The method of nonlinear regression was used ot predict the optional technological regime of the phosphate addition in the batch culture at different time intervals of additions. 相似文献

Cytologic preparations made from the tracheobronchial tree taken by the Schreiber catheter have been scanned by three color
microphotometry. The digitized cell images were processed by the analytical cytodiagnostic programs of the TICAS system. Cells
were sorted into two control groups and five groups of increasing atypia ranging from normal epithelium to invasive squamous
cell carcinoma. Standard statistical tests, including Wilk's Lambda, Rao's V, and the Kruskal-Wallis tests are performed on
these subsets of cell image features. This study demonstrates that discriminant analyses permit differentiation between normal
cells and those from marked atypia or carcinoma and that the classification achieves a high degree of agreement with visual
assignment. 相似文献
