Peatlands play an important role in the global carbon (C) cycle due to their large C storage potential. Their C sequestration rates, however, highly vary depending on climatic and geohydrological conditions. Transitional mires are often characterised by floating peat with infiltration of buffered groundwater or surface water. Sphagnum mosses grow on top, producing recalcitrant organic matter an...

Aloe vera is one of the most popular cactus-type plants in global market due to its widespread uses pharmaceutical, cosmetic, food, and decorative purposes. The present study derived callus cultures from plant leaves, then reproduced on agar-solidified MS medium June December 2021 at University Mosul, Iraq. Results revealed that + 3.0 mg L-1 benzyl adenine (BA) proved suitable for induction lea...

To study the effect of different substrates on growth and yield of gerbera, this experiment was carried out as randomized completely block design with 14 treatments and 3 replications. Treatments were as fallowing: fine sand, peat+fine sand (25%+75%), peat+fine sand (50%+50%), perlite+peat (75%+25%), perlite+peat (50%+50%), perlite+peat (25% +75%), perlite+peat+expanded clay (25%+70%+5%), perli...

Terrestrial mosses are commonly used as bioindicators of atmospheric pollution. However, there is a lack of standardization of the biomonitoring preparation technique and the efficiency of metal adsorption by various moss species is poorly known. This is especially true for in vitro-cultivated moss clones, which are promising candidates for a standardized moss-bag technique. We studied the adso...

Sphagnum (spp.) is widely distributed in permafrost regions around the arctic and subarctic. The moisture content of the moss layer affects the thermal insulative capacity and preservation of permafrost. It also controls the growth and collapse history of palsas and other peat mounds, and is relevant, in general terms, to permafrost thaw (therrnokarst). In this study, we test and calibrate seve...

This study was conducted at Abi – Jarash farm, Damascus, Syria, during 2018/2019 and 2019/2020 growing seasons. The aim of this comparing the effect three different cultivation techniques saffron (Crocus sativus L.), which were soilless cultivation, within nutrient film technique (NFT), in substrates (mixture peat moss- perlite), addition to soil. An increasing vegetative growth measurements re...
