The content of total lipids and lipofuscins was determined in leaves of S. latifolium aerial-aquatic and terrestrial plants at the flowering and fruiting phases. There were no significant differences in the lipid total content between aerial-aquatic and terrestrial plants at the flowering phase. At the fruiting phase, the lipid content was lower in terrestrial plants. Lipofuscins, the so-called senescence pigments, were determined in plants of both ecotypes at the flowering phase, although visible symptoms of senescence were absent. At the fruiting phase, there was an accumulation of lipofuscins in aerial-aquatic and terrestrial plants that may be explained by progressive senescence. The lipofuscin content was higher in terrestrial plants at both phases of ontogenesis. We concluded that earlier and more intensive senescence is typical for terrestrial plants, which are in the conditions of chronic moderate water deficit on the riverside.

The interaction between foliar treatment with 100 mg∙dm–3 of both gibberellic acid 4+7 (GA4+7) and benzyladenine (BA) and vase solution containing 3% sucrose was analysed in cut Lilium ‘Alma Ata’. GA4+7+BA considerably delayed leaf senescence, suppressed anthocyanin accumulation in the leaves of plants held in the sucrose solution and improved the average longevity of the flowers and the vase life of the stems. Sucrose in the vase solution strongly reduced the abscission of leaves and contributed to the enlargement of the top flower. The number of significant interactions between the treatments indicated that the investigated factors acted dependently mainly on flower quality, while their action on leaf quality was mostly independent. Results show that combined treatment with growth regulators and sucrose may considerably increase postharvest quality of cut Lilium ‘Alma Ata’.

Recently transgenic potato plants were created where the 14-3-3 protein derived from Cucurbita pepo was overexpressed or potato endogenous 14-3-3 protein repressed. Detailed analysis of those plants suggested that a isolated 14-3-3 isoforms are involved in the control of plant senescence and carbohydrate metabolism. In this study carbohydrate content, adenine nucleotide level and catecholamine content in tubers and leaves of transgenic plants grown in greenhouse and in a field were compared. Overexpressing of 14-3-3 protein gave rise to increase catecholamine contents and soluble sugars in leaves and a reduction in tubers size and starch content. The repression of 14-3-3 synthesis led to opposite effect, a decrease in catecholamine, soluble sugars contents in leaves, and an increase in tubers size and starch content. It is proposed that 14-3-3 protein affects carbohydrate metabolism in potato via regulation of catecholamine synthesis.
