Selva) were transferred to nutrient solutions with or without iron. After 35 d of growth, plants in the solution without iron became chlorotic and had morphological changes in roots typical of iron\u2010deficiency chlorosis (IDC). Acidification of the nutrient solution was also observed. We tested a grass\u2010clipping extract to correct IDC in strawberry plants by foliar application to some chlorotic plants. We also assessed the effects of this product on plant growth, Fe allocation, as well as morphological and physiological parameters related with IDC. After the second spray, leaf chlorophyll increased in the youngest expanded leaves. The total content of iron in plants increased from 1.93 mg to 2.37 mg per plant after three sprays, accounting for 80% of the total iron supplied by the extract. Newly formed roots from sprayed plants had a normal morphology (no subapical swollen zone) but a higher ferric chelate\u2013reductase (FC\u2010R; EC 1.16.1.17) activity per root apex compared with roots from plants grown with iron or untreated chlorotic plants. Acidification of the nutrient solution continued in sprayed recovered plants. The results suggest an uncoupling of the regulation of morphological and physiological mechanisms related to IDC: FC\u2010R activity seems to be controlled by roots on their own or together with shoots, while morphological changes in roots are apparently regulated only by the level of iron in shoots.<\/jats:p>","DOI":"10.1002\/jpln.201000215","type":"journal-article","created":{"date-parts":[[2011,4,12]],"date-time":"2011-04-12T01:59:55Z","timestamp":1302573595000},"page":"473-479","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Strawberry recovers from iron chlorosis after foliar application of a grass\u2010clipping extract"],"prefix":"10.1002","volume":"174","author":[{"given":"Maribela","family":"Pestana","sequence":"first","affiliation":[]},{"given":"Irina","family":"Domingos","sequence":"additional","affiliation":[]},{"given":"Florinda","family":"Gama","sequence":"additional","affiliation":[]},{"given":"Susana","family":"Dandlen","sequence":"additional","affiliation":[]},{"given":"Maria\u00a0Gra\u00e7a","family":"Miguel","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o","family":"Castro Pinto","sequence":"additional","affiliation":[]},{"given":"Amarilis","family":"de Varennes","sequence":"additional","affiliation":[]},{"given":"Pedro\u00a0Jos\u00e9","family":"Correia","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2011,4,11]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"A.
