Megjegyzések:	Greenhouse experiments were conducted to evaluate the utilization of compost derived from grape fruit waste (GFW) as an ingredient in nursery substrates for germination and development of cucumber. A randomized complete block design was used with thirteen treatments (S1-S13) encompassing 100% composted GFW, 60% GFW + 40% poultry manure including hardwood sawdust, 80% GFW + 20% broad bean straw, 80% GFW + 20% poultry manure including wheat straw, 50% coco peat + 50% vermiculite (as a control) and different combination of GFW-based composts with either coco peat or vermiculite. The resulted illustrated that GFW mixed with broad bean straw and poultry manure regardless of its source improved the chemical properties of composted GFW. Composts of GFW were even richer in nutrients, i.e., N, P, K, organic matter, soluble cations and anions and C/N ratio than control (50% coco peat + 50% vermiculite) except pH and electrical conductivity (EC), which was lower. Concentration of Cu, Fe, Cd and Pb were significantly lower in GFW composts than control substrate; while total phenolic content was significantly the highest in single compost of GFW. Mixing GFW composts with either vermiculite or coco peat (at 1:1 ratio by volume) was optimal for seed germination and seedling growth parameters; those combined substrates showed the highest FGP, CGRI, survival rate, and growth parameters in most cases. The negative effects of singly GFW compost can be removed or improved by mixing it with coco peat or vermiculite, so seed germination, seedling growth and survival rate significantly enhanced with mixing GFW-compost with coco peat or vermiculite substrates at ratio of 1:1. These recycled wastes are low cost products that can be usefully used in horticultural nurseries on a commercial scale.

Megjegyzések:	Selenium (Se) is a naturally occurring metalloid element which occurs nearly in all environments. Se is considered as a finite and non-renewable resource on the Earth. The common sources of Se in earth's crust occur in association with sulfide minerals such as metal selenide, whereas it is rarely found in elemental form (Se0). While there is no evidence of Se need for higher plants, several reports show that when Se added at low concentrations, Se exerts beneficial effects on plant growth. Se may act as quasi-essential micronutrient through altering different physiological and biochemical traits. Thus, plants vary considerably in their physiological and biochemical response to Se. This review focusses on the physiological importance of Se forms as well as different Se fertilizers for higher plants, especially plant growth, uptake, transport, and metabolism.

Cím:	Selenium fortification induces growth, antioxidant activity, yield and nutritional quality of lettuce in salt-affected soil using foliar and soil applications / Tarek Shalaby, Yousry Bayoumi, Tarek Alshaal, Nevien Elhawat, Attila Sztrik, Hassan El-Ramady

Megjegyzések:	Aims Distribution of selenium (Se) in soils around the world is not identical and many soils are classified as Sepoor soils. Therefore, Se fortification of crops grown on these soils is crucial, where increasing Se intake by human - below toxic threshold - is vital for better health. The recent work aims to investigate the possible use of Se to alleviate the detrimental effects of soil salinity on lettuce and enhance its growth, yield quality and Se enrichment. Methods Field experiments were conducted during two successive seasons (2016 and 2017) in salt-affected soil (EC 4.49 dS m?1, pH 8.65) using four concentrations of Se (0, 50, 75 and 100 ppm) by three different application methods. Antioxidant capacity, ion leakage, Se content in plant and soil, yield and vegetative parameters of lettuce were measured. Results The results showed that Se addition mitigated the detrimental effect of salinity on lettuce growth and its development. Se application (100 ppm) increased also the head weight, leaf area, leaves dry weight and chlorophyll content by 46.4, 66.4, 61.8 and 31.5%, respectively, compared to control plants. Likewise, catalase (CAT) and ascorbate peroxidase (APX) activities increased by 108.8 and 123.6%, respectively, as a result for using 100 ppm of Se. Otherwise, Se (100 ppm) reduced the electrolyte leakage from lettuce leaves by 68.4% against control. The positive effect of Se (100 ppm) on lettuce under salinity was fully verified with data of total yield which increased by 42.1% over control. Foliar application increased Se content in lettuce without exceeding the toxic level and residual Se in soil was the lowest among other treatments. Conclusion The present work reports that in saltaffected soils spraying lettuce with Se (100 ppm) improves its growth, antioxidant capacity, Se fortification and yield quality.
