Complementary Evaluation of Iron Deficiency Root Responses to Assess the Effectiveness of Different Iron Foliar Applications for Chlorosis Remediation
Iron deficiency in plants is caused by a low availability of iron in the soil, and its main visual symptom is leaf yellowing due to a decrease in chlorophyll content, along with a reduction in plant growth and fruit quality. Foliar sprays with Fe compounds are an economic alternative to the treatment with expensive synthetic Fe-chelates applied to the soil, although the efficacy of foliar treat...
متن کاملAlkaline stress and iron deficiency regulate iron uptake and riboflavin synthesis gene expression differently in root and leaf tissue: implications for iron deficiency chlorosis
Iron (Fe) is an essential mineral that has low solubility in alkaline soils, where its deficiency results in chlorosis. Whether low Fe supply and alkaline pH stress are equivalent is unclear, as they have not been treated as separate variables in molecular physiological studies. Additionally, molecular responses to these stresses have not been studied in leaf and root tissues simultaneously. We...
متن کاملSelection of olive varieties for tolerance to iron chlorosis.
Under certain conditions, olive trees grown on calcareous soils suffer from iron chlorosis. In the present study several olive varieties and scion-rootstock combinations were evaluated for their tolerance to iron chlorosis. Plants were grown over several months in pots with a calcareous soil, under two fertilization treatments. These consisted of periodic applications of nutrient solutions cont...
متن کاملIron deficiency-induced secretion of phenolics facilitates the reutilization of root apoplastic iron in red clover.
Phenolic compounds are frequently reported to be the main components of root exudates in response to iron (Fe) deficiency in Strategy I plants, but relatively little is known about their function. Here, we show that removal of secreted phenolics from the root-bathing solution almost completely inhibited the reutilization of apoplastic Fe in roots of red clover (Trifolium pratense). This resulte...
متن کاملThe Phosphorus-Iron Relationship in Genetical Chlorosis.
Variegation of leaves is found widely distributed in the genera of the plant kingdom. Many forms are of great intrinsic beauty and are therefore a common feature in estates and gardens. The chlorotic areas usually appear as pale edges of varying width and regularity around and overlying an otherwise apparently normal green leaf, but very often whole leafy branches may appear colourless while ot...
