Opis:
This theoretical article presents a case for a new approach to the teaching of word recognition in English as a foreign language to young learners in Polish early years education, arguing that there is a need for greater attention to explicit instruction in alphabetic principles, selected phonics and decoding skills. Research in first language (L1) English and foreign language (L2) development of word recognition skills is outlined. Differences between the orthographies of Polish and English are highlighted. Approaches used in L1 early reading instruction are contrasted with those commonly applied in L2 settings. The need for more explicit instruction is rationalized on the basis of a brief description of impressions from 20 hours of classroom observation. The second part of the paper presents some principles for the design of materials to introduce alphabetic principles of English and elements of phonics to support word recognition, with examples. The ability to recognize words rapidly and with ease is a key skill, which, unless mastered early, could potentially have a negative impact on the whole of a child’s language education.

Opis:
The article examines the possibilities of fostering young L2 learner print awareness via teaching for conversing about and reflecting on writing. In order to achieve this goal the present author conducted the qualitative research on a group of 2nd-graders engaged in the performance of a series of open-ended L2 written tasks accompanied by L1 cues. The analysis of collected data shows that drawing children’s conscious attention to writing might encourage the constructive transferability of linguistic skills from L1 to L2, thus being conducive to the development of logical thinking necessary for the enhancement of their print awareness.

scoping review
Opis:
This scoping review explores the causal relationship between morphological instruction and reading development in young L2 learners by synthesizing 12 primary studies published between 2004 and 2019 (N = 1,535). These studies focused on reading English as the target language and involved participants between kindergarten and Grade 12 from four countries (China, Egypt, Singapore, and the USA). Findings suggested that (a) morphological instruction led to consistent and positive gains in L2 children’s morphological awareness and vocabulary knowledge, and the effect sizes (Cohen’s ds) ranged from small to large; and (b) the relationship between morphological instruction and other outcomes such as phonological awareness, word reading accuracy, word reading fluency, spelling, and reading comprehension was inconclusive. Notably, transfer effects of L2 English morphological instruction on novel word learning in English or on reading development in an additional language were only examined and observed in four primary studies. Discussion was provided regarding future instructional and research design.

Opis:
At the stage of the first or second leaf christmas rose seedlings were pricked to pots or to multiple pots, the roots being rolled or nipped off during the operation. The quality of young plants was estimated by determining the fresh weight, number, and length of leaves and roots. The best quality of young plants was obtained from christmas rose seedlings pricked at the stage of the second leaf and with roots rolled when planted to pots.
Siewki ciemiernika białego pikowano do doniczek lub wielodoniczek, w stadium pierwszego lub drugiego liścia właściwego, zwijając lub uszczykując korzenie w trakcie tej czynności. Jakość rozsady oceniono, określając świeżą masę, liczbę i długość liści oraz korzeni. Dobrą jakość rozsady uzyskano z siewek ciemiernika białego, których korzenie zwijano w trakcie pikowania do doniczek w stadium drugiego liścia właściwego.

Opis:
The aims of the study were to identify the fungi associated with the decay of thin roots (1-5 mm) of 1, 3 and 15-year-old Fraxinus excelsior plants and to estimate the pathogenicity of certain fungi. In total, 400 fungal isolations were performed from which 334 cultures were obtained. Altogether, 26 species of fungi were identified. The following species were most frequently obtained, independently of plant age and origin: Alternaria alternata, Chaetomium globosum, Cryptosporiopsis sp., Fusarium oxysporum, F. solani and Cylindrocarpon destructans. The last three of these were then used in an inoculation test. F. oxysporum caused the death of over 80% of 2-month-old seedlings grown in boxes containing perlite and kept in a growth chamber.

Opis:
Phytochemicals, proximate, minerals and anti-nutrient compositions of young cocoyam (Colocasia esculenta) leaves were determined using standard methods. Qualitative and quantitative analyses for phytochemicals confirmed the presence of bioactive constituents such as alkaloids, flavonoids and saponins in appreciable amounts, while terpenes, cardiac glycocides and tannins were only present in trace concentrations. Mineral analysis revealed that K recorded the highest content - with 214.00 ± 2.11 mg/100g, followed by Ca - 157.10 ± 1.47 mg/100g, Mg - 63.00 ± 0.58 mg/100g, P - 32.00 ± 0.61 mg/100g, while Fe had the lowest value - 0.10 ± 0.14 mg/100g. Proximate composition analysis of C. esculenta leaves indicated that CHO, protein and crude fibre were present in high quantities (35.22, 17.10 and 16.41 % respectively), while fat was at the lowest content (8.82%). Anti-nutritional factor analysis of young leaves of C. esculenta indicated that phytates was present in huge quantity - 11.03 ± 0.12mg/g, followed by oxalates - 7.62 ± 0.14 mg/g, while tannins recorded the lowest anti-nutritional contents - 0.12 ± 0.06 mg/g. This study has also revealed that the young leaves of C. esculenta contain appreciable levels of bioactive components (phytochemicals such as as alkaloids, flavonoids and saponins; minerals K, Ca, Mg, P and Fe) and appreciable amounts of CHO, protein and crude fibre. The results of anti-nutrients analysis showed high contents of phytate and oxalate. The last is probably responsible for the itching effect and also interferes with the utilization of essential nutrients. Thus, young leaves of C. esculenta provide appreciable quantities of nutrients and thus can rival other conventional vegetables normally consumed in Nigeria.

Opis:
The effects of drought stress, stress by increased nitrogen depositions and the combined effect of the two stress factors on the growth of Norway spruce Picea abies (L.) Karst. were studied in two stands. The drought stress was induced by reducing atmospheric precipitations by 60% and the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a rate corresponding to 100 kg N ha–1 year–1. All stress factors under study affected the height increment of the above-ground part, the length and colour of needles, and the biomass, vertical distribution, functionality and mycorrhizal infection of fine roots. The root system responded to the simulated stresses right from the the very first year of their action, exhibiting a greater damage than the above-ground part of the plant. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors.
