Common chicory performance as influenced by iron concentration in the nutrient solution.

摘要: An experiment was carried out from February 25 till April 10 of 2010 at the Jaboticabal campus Paulista State University (UNESP), state Sao Paulo, Brazil, viewing to find which would be optimum and phytotoxic levels iron in nutrients solution for common chicory (Cichorium intybus) plants. Iron concentrations were 0.9, 2.7, 8.3, 25 mg L−1. These treatments replicated 4 times experimental units distributed according a randomized complete block design. The nutrient film hydroponic technique (NFT) used. Growth parameters such as plant height number leaves well reproductive green dry mass production evaluated. optimal found between 2.7 8.3 mg L−1 solution. concentration caused toxicity, although no visual sign excess observed.
