Our study was to develop a rapid and successful method for promoting asymbiotic seed germination and growth and development of protocorm like bodies (PLBs) and subsequent plantlets of Phalaenopsis orchid. Four basal media i.e. Murashige and Skoog (MS), half strength MS (½MS), Knudson C (KC) and, Vacin and Went (VW) supplemented with coconut water and peptone were examined for their effectivenes...

Abstract—Soil samples were collected from and around Alkomos cement factory, Alkomos town, Libya. Soil physiochemical properties were determined. In addition, olive leaves were scanned for their fungal content. This work can conclude that the results obtained for the examined physiochemical characteristics of soil in the area studied prove that cement dust from the Alkomos cement factory in Lib...
assessment and management of the environmental impacts of forest harvesting operations have become increasingly critical factors in practicing commercial forestry. this study investigated soil disturbance from a forest logging system operation on an 8-hectare mixed broadleaved stand in compartment no. 309 in gorazbon district in kheyrud educational and research forest. the objective of this stu...
Bu çalışma, farklı dozlardaki melatonin (MEL) uygulamalarının (0, 5, 10 µM) kireçli ortamda yetiştirilen çilek fidelerinin yaprak, gövde ve köklerindeki bazı mineral element içerikleri üzerine etkilerini belirlemeyi amaçlamıştır. Deneme “Albion” çeşidine ait frigo fideler ile 1:1 oranında torf perlit %1 kireç ilave edilmiş karışımla doldurulan saksılarda yürütülmüştür. Farklı gelişim aşamaların...
in this research the effect of randomly reinforced soil and soil cement with different percent of cement and fiber and different length of fiber was investigated. samples were prepared according to the maximum dry unit weight and optimum water content due to the corresponding compaction curves. compressive and tensile strength were conducted on samples for different curing times. regression equ...
