traditionally, in suburbs of tabriz city, northwest iran (gps 38˚06΄n, 46˚15΄e, mean temperature of 6.6-20.0°c, sandy loam soil type), different types of vegetables including cabbages have been cultivated for many years. the cabbage cyst nematode, heterodera cruciferae was reported as one of the plant parasitic nematodes infecting kohlrabi (brassica oleracea l. var. gongylodes) and white cabbag...

It was previously reported that magnesium ion inhibited carbonic anhydrase (Bamberger and Avron 1975 Plant Physiol 56: 481-485). Studies with partially purified carbonic anhydrase from spinach (Spinacia oleracea L.) chloroplasts show that the effect was the result of the chloride counterion and not the magnesium ion. Enzyme activity was reduced 50% upon addition of 3 to 10 millimolar MgCl(2) or...

Corn (Zea mays, L.), bean (Phaseolus vulgaris L.), barley (Hordeum vulgare L.), spinach (Spinacia oleracea L.), and sugarbeet (Beta vulgaris L.) grown under iron deficiency, and Potamogeton pectinatus L, and Potamogeton nodosus Poir. grown under oxygen deficiency, contained less chlorophyll than the controls, but accumulated Mg-protoporphyrin IX and/or Mg-protoporphyrin IX monomethyl ester. No ...

Acetate concentration in spinach (Spinacia oleracea L.) leaf tissue has been determined by direct measurement in a leaf extract to oe 70 |xm or less. Additional evidence for such low acetate levels came from isotope dilution experiments where the [ l 14C]acetate incorporation into fatty acids was assayed using purified chloroplasts in the presence o f tissue extracts. Pyruvate dehydrogenase com...

The present study was designed to investigate the protective effect of the aqueous extract of Portulaca oleracea against hyperglycemic, oxidative damage and inflammation in the serum of streptozotocin (STZ)-induced diabetic rats. In the present study, the rats were divided into the following groups of 8 animals each: control, untreated diabetic, 3 Portulaca oleracea (100, 200, 400 mg/kg/d)-trea...
