Anggrek Dendrobium sp. adalah salah satu jenis anggrek yang diminati dalam pasar anggrek. Masalah kekeringan merupakan kendala aktivitas pertumbuhan secara fisiologis maupun morfologis. Salah cara dapat digunakan untuk mengembangkan kultivar resisten terhadap cekaman yaitu dengan seleksi kultur in vitro planlet PEG 6000. Tujuan penelitian ini mengetahui kisaran konsentrasi 6000 toleran dan meng...

C-phycocyanin from Spirulina platensis was purified in aqueous two-phase systems (ATPS) of polyethylene glycol (PEG)/potassium phosphate, varying the molar mass of the PEG. Results using a full factorial design showed that an increase in the concentration of salt and decrease in the concentration of PEG caused an increment in the purification factor for all the ATPS studied. Optimization of the...

In Central Europe, European beech (Fagus sylvatica L.) wood has a high potential for the production of construction and decorative materials, with aim replacing Norway spruce, oaks, other traditionally used tree species. However, biological resistance wood—to decaying fungi, molds, insects—is low, in damp conditions its must be increased suitable preservatives or modification methods. present e...

Seed is a fundamental tool to carry out breeding processes and for the propagation of crops; however, seed generally has low irregular germination. Passion fruit (Passiflora) species are economically important Ecuador, which main exporter passion concentrate in Latin America. Ecuadorian farmers propagate new plants by seeds establish orchards or extend their cultivated area. The objective this ...

The comparative assessment results of the hypoglycemic activity a combined preparation containing microcapsules with phytocomposition consisting Glycyrrhiza glabra L. extracts, dry extract Galega officinalis L . , Mentha piperita ., and gliclazide, are discussed in article. Methods for obtaining an original PEG-6000 shell described. aim study was to develop optimal technology antidiabetic subst...

Wheat is an important cereal crop worldwide that often suffers from moisture deficits at the reproductive stage. Polyethylene glycol (PEG)-treated hydroponic conditions create negative osmotic potential which is compared with moisture deficit stress. An experiment was conducted in a growth chamber to study the effects of PEG on root hair morphology and associated traits of wheat varieties. Plan...
