Fungi in Living and Dead Stems and Stumps of Pinus mugo on Coastal Dunes of the Baltic Sea
Communities of xylotrophic fungi were studied in wood of Pinus mugo of different qualities: (i) living stems, (ii) cut stumps, (iii) burned snags, (iv) cut burned stumps, (v) stems recently killed by root rot, and (vi) old snags of root rot-killed trees. A total of 277 isolates representing 58 fungal taxa were obtained from 300 wood samples (50 samples per each substrate category). Results of the present study suggested that following different disturbances (tree felling, forest fire or root rot), fungal communities likely evolve in different directions: depending on its origin (cut, burned or killed by the disease), dead wood might be inhabited by principally different microbial assemblages, and that fire has less effect on community structures than tree felling or root rot.

Evaluation of blackberry and hybrid berry cultivars new to Polish climate - Short communication
The following 13 blackberry cultivars new in Poland were tested: Black Butte, Boysenberry, Chester Thornless, Helen, Karaka Black, Kotata, Loch Ness, Loch Tay, Loganberry, and Oregon Thornless. The experiment was conducted between 2005 and 2010 in central Poland with the main focus on resistance of the cultivars to adverse local environmental conditions, as well as to assess the yield and fruit quality. Analysis of data on fruit yield and fruit weight indicated significant differences between cultivars and years. There were slight differences in harvest date from year to year. Cv. Chester Thornless had the greatest yield - avg. 12.9 kg/plant (2007-2008). All of the hybrid berries and the trailing blackberries had yields that were not different - below 3.5 kg/plant. Cvs Black Butte and Karaka Black had the heaviest fruit, above 6.0 g (2006) and up to 10 g per fruit (2007 and 2008). Cv. Oregon Thornless had the smallest fruits - 2.1 g per fruit (2006) and up to 3 g (2007, 2008). The experiment showed that plants were influenced by the Polish weather conditions.

NEEDLY, a Pinus radiata ortholog of FLORICAULA/LEAFY genes, expressed in both reproductive and vegetative meristems
The LEAFY/FLORICAULA genes from Arabidopsis and Antirrhinum are necessary for normal flower development and play a key role in diverse angiosperm species. A homologue of these flower meristem-identity genes, NEEDLY (NLY), has been identified in Pinus radiata. Although the NLY protein shares extensive sequence similarity with its angiosperm counterparts, it is lacking the proline-rich and acidic motifs thought to function as transcriptional activation domains. NLY already is expressed during vegetative development at least 5 years before the transition to the reproductive phase. Expression of NLY in transgenic Arabidopsis promotes floral fate, demonstrating that, despite its sequence divergence, NLY encodes a functional ortholog of the FLORICAULA/LEAFY genes of angiosperms. Expression of the LFY::NLY transgene can largely complement the defects in flower development caused by a severe lfy allele.

Diminished UV radiation reduces the spread and population density of Macrosiphum euphorbiae (Thomas) Hemiptera: Aphididae in lettuce crops
UV-absorbing covers reduce the incidence of injurious insect pests and viruses in protected crops. In the present study, the effect of a UV-absorbing net (Bionet) on the spatio-temporal dynamics of the potato aphid on lettuce plants was evaluated. A field experiment was conducted during three seasons in two identical tunnels divided in four plots. A set of lettuce plants were artificially infested with Macrosiphum euphorbiae adults and the population was estimated by counting aphids on every plant over 7 to 9 weeks. Insect population grew exponentially but a significantly lower aphid density was present on plants grown under the UV-absorbing cover compared to a standard 50 mesh net. Similarly, in laboratory conditions, life table parameters were significantly reduced under the Bionet. Moreover, SADIE analysis showed that the spatial distribution of aphids was effectively limited under the UV-absorbing nets. Our results indicate that UV-absorbing nets should be considered as an important component of lettuce indoor cropping systems preventing pesticide applications and reducing the risk of spread of aphid-borne virus diseases.

Effect of various weather conditions on selectivity of post-emergence herbicides in sugar beet
The basis for selectivity of phenmedipham, desmedipham and ethofumesate, incl. their mixtures, on sugar beet was studied under field conditions. The effect of many herbicides on sugar beet is affected by weather; therefore the sensitivity of sugar beet after herbicide application was studied to determine the effect of environmental conditions on the chemicals selectivity. The effects of herbicides on the rates of CO2 uptake and transpiration, as well as chlorophyll fluorescence (Fv/Fm) of intact plants were measured. Under the optimal spraying conditions, mean Fv/Fm in sugar beet treated with phenmedipham + desmedipham + ethofumesate was 30 % lower compared to untreated check variant, while the value decreased to a lesser extent (15 %) when treated under unfavorable conditions. Treatments with phenmedipham alone caused 10 % decrease and statistically significant differences in relation to environmental conditions at spraying were not observed. Fv/Fm parameter showed that sugar beet was not affected by desmedipham injury as much as by phenmedipham. Photosynthesis was significantly reduced first day after treatment with phenmedipham + desmedipham + ethofumesate when treated under the optimal spraying conditions. The magnitude of net photosynthesis rate decrease was lower when treated with one active ingredient solely. Under the optimal environmental conditions, the sugar beet plants were more affected by herbicides than by the treatment in unfavourable conditions shortly after the herbicide treatment. Later, sugar beet plants recovered substantially.

The impact of different growing years on selected sugar beet growth and yield parameters
The field multifactorial experiment with Renata and Kristall sugar beet genotypes was based on agricultural farm Moèenok in four replicates by chess-board method in 1998 and 1999 (maize growing region, warm and dry climatic region with mild winter, chernozem, medium soil, pH 7.2). The experimental area was 480 square m in both years, 1998 and 1999. Fertilization treatments: treatment A (control) = 0 kg/ha N + 0 kg/ha P + 0 kg/ha K; treatment B = 40 kg/ha N + 35 kg/ha P + 250 kg/ha K; treatment C = 80 kg/ha N + 35 kg/ha P + 250 kg/ha K; treatment D = 120 kg/ha N + 35 kg/ha P + 250 kg/ha K. Farmyard manure (40 t/ha) was applied under forecrop (winter wheat), with minimisation soil treatment (middle soil tillage left out). The growth parameters were calculated as follows: LAI = A/P (square m/square m); NAR = (W2_W1)/(t2_t1) . (1/A) (g/square m/day); CGR = (W2_W1)/(t2_t1) . (1/P) (g/square m/day); where: LAI = leaf area index, NAR = net assimilation rate, CGR = crop growth rate, A = leaf area (square m), P = soil area (square m), W1 = leaf dry weight, sugar beet root dry weight at the beginning of the observation interval / on the end of the observation interval W2 (g), t1 = time at the beginning of the observation interval / at the end of the observation interval t2 (day). Biological yield (BU) was determined on the basis of sugar beet roots dry weight and above ground biomass at the time of sugar beet harvesting. Leaf area index (LAI) was detected by planimetric method in 6 repetitions. The material on growth analysis was sampled in terms: 21.5., 30.7., 8.9., 5.10. in 1998 and 28.5., 26.7., 30.8., 24.9. in 1999. The measured values were evaluated in Statgraphic program. Growing years which were meteorologically very different made it possible to identify the growth parameters differences of researched genotypes in strong interaction with the course of weather. Growing year 1999 with precipitation far above the average in vegetation period affected the researched sugar beet genotypes more negatively (as related to final biological dry mass yield and root dry mass yield especially) than growing year 1998 with rainfall deficit. We conclude that growth parameters evaluation is irreplaceable in detecting causality both in genotypically and environmentally caused differences in qualitative and quantitative yield markers.
