| Summary: | 10, 20, 30, or 40 mg,l-'. For solution culture studies, adjusted to a pH of 6, containing Fe as FE-EDTA at eithe@ 0, and pH of the growing media affected Fe uptake. In two associated with increased symptom severity and higher based media increased over time, thus the cumulative effects cactus. can lead to losses in crop quality. This work was conducted Christmas,"Twilight Tangerine,"Christmas Charm,'and 'Lavender correlated with applied Fe concentration, and if temperature culture, and fertilized with a modified Hoagland's solution, daylength for 16 weeks at 220C /1 80C day/night temperature. development, but was dependent on cultivar susceptibility. Doll'were placed in either a peat-based medium or solution For the peatbased studies, plants were grown in a greenhouse in the occurrence of the Fe toxicity. There did not appear In two other separate studies, results indicate that occurrence of marginal chlorosis of the phyllociade, which of repeated Fe-chelate applications are an important factor phylloclade Fe concentrations. Fe concentrations in peat- plants were placed in a growth chamber and grown under 16 hrs Production of holiday cactus has been limited by the common separate studies, rooted cuttings of Schlumbergera 'White study do not affect the toxicity expression in holiday temperature regimes and pH of the growing media used in this temperature. Increased concentration of FE-EDTA was to be a critical concentration of Fe associated with symptom to determine if poor growth and phylloclade yellowing were under long day conditions (4 hrs night interruption) for 20 weeks at temperature set points of 250C /180C day/night |
