Two lines of Picea omorika (Panc.) Purkyn? were compared with respect to germination percentage as well as specific activity and isoenzyme pattern of catalase, superoxide dismutase, and peroxidase (POD) during germination. Line A had a higher germination percentage and higher enzyme activities in dry seeds and seedlings compared to line C. Peroxidase activity was not detected in dry seeds, but measured up to 10 U/g and 28 U/g on the 7th day of germination in lines C and A, respectively. The most abundant POD basic isoform in seedlings of both lines (pI 8.2) was not found previously in needles of adult Serbian spruce trees of the same lines. .

The study was carried out in Serbian spruce (Picea omorika Panc/Purkyn?) plantations in the western Serbia. The paper presents results of the analysis of crown development. The following elements were analyzed: total tree height, height of the crown base, absolute and relative crown length, maximal crown diameter, coefficient of crown spreading and degree of crown girth. We discuss approaches to the modeling of tree crown growth and development, growing under favorable environmental and stand conditions, without anomalies in development. In order to establish the relationship between analyzed factors, regression analyses were applied. Data fitting was by the analytic method, by the implementation of Prodan?s functions of growth, linear and parabolic function. Received models can be used for the simulation of various growth and developing processes in forest.

Adenosylmethionine Synthetase

Expression of S-Adenosylmethionine synthetase (SAMS) gene in pigeon pea (Cajanus cajan L.) was analyzed by qRT PCR during abiotic stresses viz., drought, heavy metal (CdCl2) and cold. Maximum expression of SAMS gene in the leaves were observed at 3 days after drought stress with 15% PEG. Conversely, its expression was not detected in leaves and roots at cadmium stress but transcripts were down regulated as compared to the control. After 6 days of stress expression of SAMS gene was increased in leaves and roots as compared to the control but it was lower than its expression at 3 days after stress. The activities of antioxidative enzymes like glutathione reductase, glutathione-s-transferase, ascorbate peroxidase and metabolite constituents like polyamines and glycine betaine were also analyzed. The activities of antioxidative enzymes and concentration of glycine betaine showed remarkable increase in response to all stresses, except ascorbate peroxidase in heavy metal stress.

AbstractFluorescence-detected linear dichroism (FDLD) microscopy provides observation of structural order in a microscopic sample and its expression in numerical terms, enabling both quantitative and qualitative comparison among different samples. We applied FDLD microscopy to compare the distribution and alignment of cellulose fibrils in cell walls of compression wood (CW) and normal wood (NW) on stem cross-sections of juvenile Picea omorika trees. Our data indicate a decrease in cellulose fibril order in CW compared with NW. Radial and tangential walls differ considerably in both NW and CW. In radial walls, cellulose fibril order shows a gradual decrease from NW to severe CW, in line with the increase in CW severity. This indicates that FDLD analysis of cellulose fibril order in radial cell walls is a valuable method for estimation of CW severity.

The double-spined bark beetle Ips duplicatus (Coleoptera: Curculionidae, Scolytinae) is an invasive forest pest having a broad range of coniferous hosts within Europe. We found this species to be also developing in the Serbian spruce Picea omorika. Ips duplicatus infested 14 (52%) of 27 P. omorika mature trees in an arboretum garden in northern Slovakia in Central Europe during the summer of 2019. Logs from the upper part of stems of P. omorika trees placed in eclectors in the laboratory, yielded a total of 179 individuals of three scolytine species, with prevalence of I. duplicatus. Our results show that I. duplicatus also colonized less likely host such as the Serbian spruce, causing threat to this ornamental tree and contributing to its mortality in urban habitats during hot and dry summer weather.
