Activity of acid phosphatase (E.C.3.1.3.2.) in wheat seedlings associated with soil stress conditions
Wheat seedlings grown in soil containing high levels of Na C1 or Na2CO3 showed more or less delay in germination, reduction in growth and dry matter accumulation accompanied with increased acid phosphatase (E.C.3...

Effects of different sterols on the inhibition of cell culture growth caused by the growth retardant tetcyclacis
Cell division in cell suspension cultures can be completely blocked by the growth retardant tetcyclacis at a concentration of 10-4 mol l-1. In rice cells it has been demonstrated that the growth inhibition can be...

Dendritic crystal growth in pure4He
Dendritic crystal growth of pure hcp and fcc4He was observed at pressures between 210 and 6500 bar. Dendrite morphology depends on fluid supercooling and crystal phase. At large supercooling, dendrites with side ...
