Vase life of Heuchera L. leaves following the application of benzyladenine

The aim of this study was to assess vase life of leaves harvested at two dates – in the spring and summer, for 3 cultivars of Heuchera L. following the application of benzyladenine in spraying of maternal plants one day prior to leaf harvest. Leaves of cultivar ‘Southern Comfort’ were most durable, while those of cultivar ‘Purple Petticoats’ – least durable. Leaves harvested in summer had a longer vase life, except for leaves of cultivar ‘Plum Royale’. BA (300 and 600 mg·dm-3) in leaves of cultivar ‘Plum Royale’ improved vase life only in leaves harvested in the summer. BA (100 and 300 mg·dm3) in cultivar ‘Purple Petticoats’ – in leaves harvested in spring, while when used at a concentration of 300 and 600 mg·dm-3 – in those collected in the summer. BA (100–600 mg·dm-3) in cultivar ‘Southern Comfort’ considerably improved vase life of leaves cut in the spring and summer. BA inhibited protein degradation. In the tested cultivars in leaves, harvested in the spring and summer, treated with benzyladenine the content of saccharides was higher

Wpływ mikoryzacji na wzrost, kwitnienie Sinningia speciosa (Lodd.) Hiern oraz zawartość barwników chloroplastowych, cukrowców i białka w liściach

The research was conducted on two cultivars of Sinningia speciosa (Lodd.) Hiern: ‘Defiance’ and ‘Blanche de Meru’. Plants were cultivated with or without symbiosis with endomycorrhizal fungi. In order to evaluate the biochemical changes in the leaves of Sinningia speciosa at the vegetative growth stage the content of chlorophyll a+b, carotenoids, protein and saccharides was determined. Plant growth parameters, such as height, diameter, number of leaves and number of initiated flower buds, were determined when first flower was developed. Mycorrhizal plants of Sinningia ’Defiance’ and ‘Blanche de Meru’ had more flower buds, 66.7 and 57.1%, respectively. The mycorrhization had a positive influence on the content of chlorophyll a+b in the leaves of Sinningia speciosa ‘Defiance’, whereas in the Blanche de Meru cultivar this dependence was observed only in the ninth and tenth week of cultivation. At the vegetative stage the mycorrhized plants had a higher content of carotenoids in their leaves, except for the tenth week of cultivation in the Defiance and the seventh and tenth weeks of cultivation in the Blanche de Meru cultivar. The mycorrhization did not influence the content of protein in the cultivars under investigation, except for the ninth week of cultivation. The highest content of saccharides in the leaves of Defiance and Blanche de Meru cultivars was noted at the beginning of vegetation and it was similar in the mycorrhized and non-mycorrhized plants.W badaniach oceniano wpływ grzybów endomikoryzowych na zmiany, w fazie wzrostu wegetatywnego, zawartości chlorofilu a+b, karotenoidów, białka i cukrowców w liściach Sinningia speciosa (Lodd.) Hiern ‘Defiance’ i ‘Blanche de Meru’. Jakość roślin (wysokość, średnica, liczba liści i pąków kwiatowych) określono w fazie, gdy na roślinach rozwinął się pierwszy kwiat. Mikoryzacja siningii odmian Defiance i Blanche de Meru stymulowała tworzenie się pąków kwiatowych. Na roślinach mikoryzowanych rozwinęło się średnio o 66,7 i 57,1% więcej pąków kwiatowych, odpowiednio dla Defiance i Blanche de Meru., Mikoryzacja miała pozytywny wpływ na zawartość chlorofilu a+b w liściach odmiany Defiance. U odmiany Blache de Meru zależność tą obserwowano tylko w 9 i 10 tygodniu uprawy. W fazie wzrostu wegetatywnego mikoryzowane rośliny miały większą zawartość karotenoidów w liściach, za wyjątkiem odmiany Defiance w 7. tygodniu uprawy i odmiany Blanche de Meru w 7. i 10. tygodniu uprawy. Mikoryzacja nie miała wpływu na zawartość białka w liściach badanych odmian, za wyjątkiem 9 tygodnia uprawy. Podwyższoną zawartość cukrowców u obu odmian odnotowano pod koniec fazy wegetatywnej, zarówno u mikoryzowanych jak niemikoryzowanych roślin

Mycotic complications of shunt infection in children with primary hydrocephalus. Recently, the incidence of fungal infections in children, including cbildren with shunt-dependent hydrocephalus, has increased. The analysis comprised 8 cbildren treated in the III Clinic of Pediatrics of ICZMP during the period of 12 months (12% of all infectious complications of the shunt system). The clinical picture of fungal infection included Symptoms of shunt dysfunction: febrile conditions, vomiting, distress and loss of appetite. The most common pathogens isolated from the cerebro-spinal fluid were fungi from the Candida species. Mean value of pleocytosis in the cerebro-spinal fluid was 812 cell/μ, and mean protein concentration was 311 mg/dl. Treatment consisted of monotherapy with Dillucan, monotherapy with Ancotil or combined treatment with Ancotil and Amphotericine B. The drugs were administered intravenously and intraventricolarly after removal of the shunt and application of external drainage. Sterility of cerebro-spinal fluid was obtained in the shortest time with the use of Ancotil. Propbylactic application of antifungal drugs decreases the frequency of infections in children with shunt-dependent hydrocepbalus
