seed dormancy is a temporary failure of a viable seed to germinate. various methods are used for breaking seed dormancy, depending on plant species and type of dormancy. three seed populations originated from esfahan, semnan and fars provinces were exposed to different seed dormancy breaking treatments such as mechanical and chemical scarification, humid chilling, ga3 and polyethylenglycol 6000...

Chickpea (Cicer arietinum L.), an important leguminous crop has a dwindling croparea everyday due to climate change, and the overall yield declined. In controlled conditionexperiment, four distinct levels of drought were applied ten different varieties chickpeas in petridish using polyethylene glycol (PEG) @ 0, 10, 20, 30%. As differentiating factors, germinationrate, plumule, radicle lengths u...

A series of thermoplastic polymer electrolytes have been prepared employing poly(ethylene oxide) (PEO) as a polymer matrix, bis(trifluoromethane sulfonimide) (LiTFSI), and different room-temperature ionic liquids (RTIL) with bis(fluorosulfonyl)imide (FSI) or TFSI anions. This formulation makes them safe and non-flammable. The electrolytes have been processed in the absence of solvents by melt c...

Polydiacetylene (PDA) micelles coated with either carboxylate-, ammonium-, or methoxy-polyethyleneglycol (PEG) chains were assembled and loaded with a fluorescent dye (DiO). Their interaction with MCF-7 human breast tumor cells was investigated by epi-fluorescence microscopy and fluorescence-activated cell sorting (FACS) to determine their internalization pathway and intracellular fate. It was ...

Various liquid phases for glass capillary columns have been evaluated for gas-liquid chromatographic analysis of methyl ester trimethylsilylether derivatives of bile acids from serum and bile. Bile acid analysis is rapid and exhibits high separation efficiency with a 20 X 0.3 mm glass capillary column whose internal surface is covered with a crystal layer of barium carbonate and coated with pol...

ANNA W. I. VAN DAM-BAKKER AND OTHERS '958 3. The growth rate of young rats, given the high-protein and the low-protein moieties of the diet on alternate days was less than that of pair-fed, litter-mate control animals consuming both moieties together. 4. Intermittent protein feeding likewise impaired lactational capacity of the mothers and retarded recovery of the haemoglobin content of the blo...
