Seedlings of Chrysalidocarpus lutescens, Dracaena deremensis and marginata were grown in plastic containers filled with sphagnum peat-moss to assess the effects three different water systems on plant growth, saving nutrient removal during experimental period. The experiment lasted for 8 weeks consisted systems. These an open draining system fertigated a standard solution (system T0) two closed ...

somatic embryogenesis is a new approache to plant mass in vitro propagation. this method influences by elements and their components in medium. in order to investigate the effects of different media and it,s role on somatic embryogenesis of carrot, a cbd experiment with four replications (including 12 treatments) was conducted. to do this, carrot petioles (with 1 cm dimension) in induction phas...

Objective: To evaluate water consumption in ornamental plants (geranium, gazania and petunia) two substrates with different particle sizes (fine coarse) of tezontle peat moss, through a suction irrigation system, which uses porous capsules as emitters. Design/methodology/approach: The experimental design was complete randomized blocks, six treatments (three species substrates) four repetitions ...

Elemental analyses (H, N, C, O, S), bulk isotope analyses (C, N) and C content of pyrolysis products from Sphagnum moss, underlying peat from a bog and the bog water (Hohlohsee, Black Forest, Germany) were performed to identify humi®cation processes in the early diagenesis of peat formation and to determine the origin of dissolved organic matter (DOM) in the bog lake. Atomic ratios of bulk elem...

Nitrogen rate and time of application are among the major abiotic factors limiting productivity maize. The research was, therefore, carried out to examine response two maize varieties (Omankwa Pioneer hybrid) four different times N : P K 15 fertilizer during growing season in Ghana. experiment was arranged a randomized complete block design with eight treatment combinations three replications. ...

Peatland ecosystem services include drinking water provision, flood mitigation, habitat provision and carbon sequestration. Dissolved organic carbon (DOC) removal is a key treatment process for the supply of potable water downstream from peat-dominated catchments. A transition from peat-forming Sphagnum moss to vascular plants has been observed in peatlands degraded by (a) land management, (b) ...
