| Abstract: | Role of shoot in regulation of Fe~(3+)reductase activity in roots of Fe deficient cu- cumber(Cucumis sativus L.Xintaimici)plants was studied with nutrient solution culture. Iron deficiency induced an increase in Fe~(3+)reductase activity in roots.Cutting-off of either apex,apex and cotyledons or apex and first leaf could not prevent the development of the re- sponse in roots under the Fe deficient condition.Iron deficiency resulted in decrease in Fe contents in different tissues and also in phloem sap,but s... |
