The balance between reactions involving free radicals and processes which ameliorate their effect plays an important role in the regulation of plant senescence. In this study a method was developed to isolate peroxisomes and mitochondria from carnation (Dianthus caryophyllus L. cv Ember) petals. Based on electron microscopy and marker enzyme levels, the proportion of peroxisomes to mitochondria...

The lipid microviscosity of microsomal membranes from senescing cut carnation (Dianthus caryophyllus L. cv. White Sim) flowers rises with advancing senescence. The increase in membrane microviscosity is initiated within 3 to 4 days of cutting the flowers and coincides temporally with petal-inrolling denoting the climacteric-like rise in ethylene production. Treatment of young cut flowers with a...

Exposure of carnation (Dianthus caryophyllus L.) flowers to ethylene evokes the developmental program of petal senescence. The temporal relationship of several aspects of this developmental program following treatment with ethylene was investigated. Exposure of mature, presenescent flowers to 7.5 microliters per liter ethylene for at least 6 hours induced petal in-rolling and premature senescen...

The article presents the results of mycological studies conducted in 2018 and 2019 on territory Boguty Mountains. samples were collected early spring gorges Big massif. An annotated taxonomic list is provided, which includes 21 species micromycetous fungi fungus-like organisms from 17 genera, 11 families, 6 orders, 5 classes, 2 kingdoms. For 4 fungi, systematic position remains unclear. One myx...

Cryptic plant viruses are seed-borne dsRNA-viruses, which co-exist life-long with the host plant, without inducing any apparent symptoms. Since growth conditions and the hostvirus combination (cultivar, strain, isolate, thermotherapy, etc.) are known to influence virus multiplication, we wanted to find out what effect long-term tissue culturing has on the survival of carnation cryptic virus (Ca...

Background. Dianthus basuticus is a commonly used medicinal plant in Basotho traditional medicine for the treatment of diabetes, but there is no report on its safety or toxicity. Therefore, we evaluated the toxicity profile of the hydroethanol whole plant extract of Dianthus basuticus in Wistar rats. Methods. Acute toxicity test was performed with single oral administration of 100-3200 mg/kg bo...
