Putrescine and Spermidine in Peas: Effeets on Nitrogen Source and Potassium Supply
Free and total putrescine and, to a lesser extent, spemidine accumulate in both roots and shoots of peas in response to potas stum deficiency and ammomnium supply. Free putrescine responds more
Responses of amino acid metabolizing enzymes from plants differing in salt tolerance to NaCl
The results showed that DDH isolated from the salt-tolerant Atriplex species was adapted to high NaCl concentrations of the tissue, and the inhibition at low substrate concentrations was shown to be competitive.
Uninterrupted voltage supply
The device has an accumulator (14), a charging device (18) for the accumulator supplied from the d.c. voltage supply (12) and a controller (22) which connects the accumulator electrically to the
